Abstract

PURPOSE:To easily realize combined special image effect by controlling stored still image data so as to be transferred while the still images which are being synthesized based on still image data are displayed. CONSTITUTION:A program control means 12 outputs the memory information on a transfer destination (second next) and the memory information on a transfer origin (on air) to a screen control means 10. Further, based on a control table, corresponded memory numbers (the transfer destination is M1 and the transfer origin is M2) are made to be outputted to a transfer means 11. The control means 12 outputs the coordinate of the starting point of the rectangular area of the transfer destination, longidudinal and lateral sizes and the coordinate of the starting point of the rectangular area of the transfer origin to the transfer means 11. In accordance with these, the transfer of still image data by the transfer means 11 is performed. The transfer means 11 performs the image transfer of the image of the area of the rectangular size which is the same as the transfer destination (the image of the rectangular area where (0, 0) and (100, 400) are made the base end stations of a diagonal), making memory (M2) coordinate information on the transfer origin as the starting point, to the area of the same size (the rectanguar area where (0, 0) and (100, 400) are made the base end station of the diagonal) where the coordinate information on the memory (M1) on the transfer destination is made the starting point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an image reproducing apparatus with special effects of the present invention will be described below. FIG. 1 shows an image reproducing apparatus according to an embodiment of the present invention. The optical disc 1 records still image data and effect programs. The effect program is for controlling execution of image effects such as wipe, roll, dissolve, etc., and transfer of still images, as described later.

The optical disc 1 has an image data section for recording still image data and an effect data section for recording an effect program, and the image data section is divided into a plurality of image data areas. Divided into multiple effect data areas. One still image data is stored in one image data area, and one effect program is similarly recorded in one effect data area.
The image data area and the effect data area are numbered in the order of addresses, and the numbers correspond to the designated numbers of the still image data and the effect program.

On the optical disc 1, directory information recording the start addresses of the image data areas and the effect data areas is also recorded, and further volume information such as creation date, disc identification information and various flag information is recorded. Has been done. Therefore, the recorded data area can be specified by specifying the still image data and the number of the effect program, and the recorded data in each data area can be accessed by referring to the directory information.

The optical disc 1 includes a type in which the stored contents are additionally recorded, a type in which the stored contents are erased and rewritable, and the like. It may be a type. The optical disk drive 2 controls reproduction of the optical disk 1 and reads out still image data and effect program. The reproduced still image data is stored in the storage means 3, and the reproduced effect program is stored in the program storage means 8.

The storage means 3 stores still image data, and has, for example, three memories for storing one frame of still image data (M1, M2, M3). Therefore, the storage unit 3 can store still image data for a total of three frames. The synthesizing unit 4 stores the memories M1 and M in which still image data for one frame is stored.
Two memories of 2 and M3 are selected, the still image data stored in the selected two memories are combined according to the combination distribution, and one frame of the combined still image data is transferred to the D / A conversion means 5. Output.

Next, a specific example of the image effect obtained by synthesizing the still image data in the synthesizing means 4 will be described. FIG. 2 shows respective states of the lateral wipe effect and the dissolve effect. First, a case where the display is switched from the still image data in the memory M1 to the still image data in the memory M2 by the horizontal wipe effect (from left to right of the screen) will be described with reference to the upper stage of FIG.

The composite distribution of the still image data stored in the memory M1 and the still image data stored in the memory M2 becomes 1: 0, and the still image data in the memory M1 is monitored by the monitor 6.
Is displayed in. By gradually decreasing the display area (combined distribution) on the screen of the still image data in the memory M1 and sequentially increasing the display area (combined distribution) on the screen of the still image data in the memory M2,
A horizontal wipe effect is realized in which the joint between the still image data of No. 1 and the still image data of the memory M2 moves from left to right.

Further, when the combined distribution of the still image data in the memory M1 and the still image data in the memory M2 becomes 0 to 1, the screen is completely switched and the lateral wipe effect is finished.
Next, a case where the display is switched from the still image data in the memory M2 to the still image data in the memory M3 by the dissolve effect will be described with reference to the lower part of FIG.

The composite distribution of the still image data stored in the memory M2 and the still image data stored in the memory M3 becomes 1: 0, and the still image data in the memory M2 is monitored by the monitor 7.
Is displayed in. By sequentially decreasing the pixel density (combined distribution) of the entire still image data stored in the memory M2 and sequentially increasing the pixel density (combined distribution) of the entire still image data stored in the memory M3, The dissolve effect is realized in which the entire still image data in the memory M3 gradually rises on the screen while the entire still image data in the memory M2 gradually sinks on the screen.

Further, when the combined distribution of the still image data in the memory M2 and the still image data in the memory M3 becomes 0 to 1, the screen is completely switched and the dissolve effect ends. D
The / A converter 5 converts the combined still image data for one frame output from the combiner 4 into an analog signal so as to be output to the monitor 6. The monitor 6 displays still image data based on the analog signal obtained by the D / A conversion means 5. For example, the number of effective pixels that can be displayed on the screen is 1035 pixels vertically and 1920 pixels horizontally.

The initial state designating means 7 is means for setting the initial state of the apparatus of this embodiment, which is controlled based on the effect program. The initial state designating means 7 outputs the number of the effect program to be executed to the optical disc drive 2. The memory number currently displayed on the monitor 6 and the memory number to be displayed next are output to the screen management means 10.

In the initial state designating means 7, the initial state may be designated as a parameter of an execution program different from the effect program. That is, when the effect program is designated during execution of the different execution program like a subroutine from the different execution program and the effect program is executed, the effect program is changed from the different execution program to the effect program. As the parameter passed
The initial state of the effect program number, the memory number currently displayed on the monitor 6, and the memory number to be displayed next may be designated.

The program storage means 8 stores the effect program which is designated to be executed by the initial state designating means 7 and then reproduced by the optical disc drive 2. The effect program reproduced at this time is an effect program in a binary representation format that is easy for a computer to handle. That is, the execution of the effect program is performed based on the effect program in the binary representation format.

The program counter 9 sequentially designates execution commands in the effect program. When the information that the execution command has entered the execution stage is input from the program control means 12 which will be described later, the value of the program counter 9 is increased or decreased to specify the next execution command. Screen management means 1
0 performs screen management based on the memory number in which the still image data currently displayed is stored and the memory number in which the still image data to be displayed next, which is obtained by the initial state designating means 7, are stored. .

That is, the currently displayed memory is set as an on-air memory, the memory to be displayed next is set as the next memory, and the memory to be displayed next to the next is set as the second next memory. And the memory numbers (M1, M2, M) in the storage means 3 and these on-air, next and second next.
The screen is managed by providing a management table in which 3) is associated with.

The memory storing the still image data currently displayed is registered in the management table as an on-air memory, and the memory storing the still image data to be displayed next is managed as the next memory. The memory that stores the remaining still image data is registered in the management table as the second next memory and managed.

Further, when the screen control means 10 receives from the program control means 12 which will be described later, information indicating a combination command such as wipe, dissolve, roll or the like for obtaining an image effect by the combination means 4, the combination is carried out. The on-air memory number and the next memory number are output to the means 4. Then, in the synthesizing means 4, the still image data recorded in the on-air memory and the still image data stored in the next memory are synthesized as described above, and the screen is switched.

Further, the screen management means 10 updates the management table after outputting the on-air memory number and the next memory number to the synthesizing means 4. That is, the memory number of on-air is registered in the second next, the memory number of the next is registered in the on-air, and the memory number of the second next is registered in the next.

Therefore, the screen management means 10 is composed by the composition means 4
On the other hand, by constantly outputting the on-air memory number and the next memory number, updating the management table and rotating the displayed memory, the screens are switched one after another. Further, the screen management means 10 receives, from the program control means 12, the memory information of on-air, next, and second next for designating the memory of the transfer destination and the transfer source among the parameters of the transfer command for transferring the image. Then, the necessary memory number is output to the transfer means 11 by referring to the management table.

For example, on-air is M1 in the management table,
When the next information is registered as M2 and the second information is registered as M3, the memory information of the transfer destination is the second next, and the memory information of the transfer source is on-air, the transfer means 11 has the memory number M3 as the transfer destination and the memory number as the transfer source. M
1 is output. The transfer means 11 inputs a transfer command and parameters (transfer destination coordinates, transfer size, transfer source coordinates) for transferring an image from the program control means 12, and the screen management means 10 inputs the transfer destination and transfer source memory. When a number is input, the image is transferred from the memory corresponding to the transfer source in the storage unit 3 to the memory corresponding to the transfer destination in the storage unit 3 based on the input.

The area to be transferred at one time is not limited to a line segment or a rectangle and may be any area. Furthermore, the size of the area transferred at one time is not limited to a part of the still image, but may be the entire size (one frame). Hereinafter, the program control means 12 will be described together with the effect program. First, the effect program will be described.

The effect program is a program which describes the execution sequence of the image effects such as wipe, dissolve, roll, etc. in the above-mentioned synthesizing means 4 and the image transfer in the above-mentioned transfer means 11. Based on this effect program, the image effect is controlled to be executed, and
While the image effect is being executed, it is controlled so that the image is transferred to the memory used for the image effect.

Therefore, a special image effect in which image effects such as wipe, dissolve, roll, etc. and image transfer are combined on the display screen is realized. The effect data area of the effect program includes a header part, a variable initial value part,
Divided into program divisions. The header section records the recording address and data size of the next effect data area.

The variable initial value section is for recording the coordinates required for data transfer, information for memory designation, etc. as initial values of variables. Variables and initial values are recorded in association with each other in the variable initial value part, and each initial value is recorded in units of 2 bytes from the beginning of the variable initial value part. Therefore, when the execution of the effect program is started, the variable initial value part is referred to in order to obtain the initial value required according to the variable in the parameter of each command.

The program section is an area for recording an effect program. FIG. 3 is a diagram showing the contents of the effect program. The program part is formed of commands and parameters as shown in FIG. Each parameter consists of variables and constants. Next, each item of the effect program of FIG. 3 will be described.

Item 1 is a dissolve command for designating the above-mentioned dissolve effect, and a variable (variable 1) indicating the effect execution time is designated as a parameter. Item 2 is a rectangle transfer command, and the coordinates of the start point (variable 2, variable 3) of the rectangular region of the transfer destination, the vertical and horizontal sizes (variable 4, variable 5) and memory information (variable 6,
Transfer destination information consisting of on-air, next and second next) and transfer source information consisting of coordinates (variable 7 and variable 8) of the starting point of the rectangular area of the transfer source and memory information (variable 9) are designated as variables. ing. Further, the coordinate of the start point of the transfer destination rectangular area, the vertical and horizontal sizes, and the increase / decrease value of the coordinate of the start point of the transfer source rectangular area are designated as constants.

Item 3 is a loop command in which the number of loops and the label number are specified as constants as parameters. Further, in the loop command, the label number is set to the command (rectangle transfer command of item 2) which is the loop destination (branch destination). Item N is an end command, and the execution of the effect program ends when this command is executed.

Next, the operation of the program control means 12 executed based on the above-mentioned effect program will be described. The program control means 12 uses the program counter 9
The execution mode is controlled by interpreting the execution command and its parameters specified by. When a synthesizing command such as wipe, dissolve, roll or the like that obtains an image effect by synthesizing by the synthesizing unit 4 is specified among the execution commands,
The combined distribution is output to the combining means 4 and information indicating a combined command is output to the screen management means 10.

Further, when a transfer command for transferring an image is specified among the execution commands, the memory information (on-air, next, second-next information) of the transfer destination information and the transfer source information is sent to the screen management means 10. Then, the remaining coordinates and size information are output to the transfer means 11. For example, in the initial state designating means 7, the on-air memory M
It is assumed that the effect program is executed in a state where it is set to 1, the next is set to the memory M2, and the second next is set to the memory M3.

When the program counter 9 designates the dissolve command of item 1, the program control means 12 obtains from the program storage means 8 a variable for storing the parameter of the dissolve command, that is, the effect execution time, and further the variable initial value part. The effect execution time (for example, 16 seconds) is obtained by referring to, and the initial value is set in the variable 1. Since the effect execution time is selected from among the predetermined candidates,
The composition distribution is calculated based on a composition table in which the composition distribution of the on-air memory and the composition distribution of the next memory are associated with each other and output to the composition means 4.

After that, the information for the command for composition is outputted to the screen management means 10, and the composition means 4 is made to output the on-air memory number M1 and the next memory number M2. Therefore, the synthesizing means 4 starts the function to exert the dissolve effect from the on-air (memory M1) to the next (memory M2). Along with this, the screen management means 10 updates the management table, and the on-air becomes the memory M2, the next becomes the memory M3, and the second next becomes the memory M1.

Next, the program control means 12 instructs the program counter 9 to update the program counter, whereby the program counter 9 specifies the rectangular transfer command of the next item 2. Therefore, the dissolve command of item 1 is executed, and the rectangular transfer command is executed during execution of the dissolve effect that takes a predetermined time (16 seconds) until the effect ends.

The program control means 12 transfers from the program storage means 8 parameters of the rectangular transfer command, that is, transfer destination information consisting of coordinates of the starting point of the rectangular area of the transfer destination, vertical and horizontal sizes, and memory information, and a rectangular area of the transfer source. A variable for storing the starting point coordinates and transfer source information consisting of memory information is obtained, various information is further obtained by referring to the variable initial value part, and an initial value is set in each variable.

For example, the coordinates of the starting point (variable 2, variable 3) of the transfer destination rectangular area are (0, 0), and the vertical and horizontal sizes (variable 4, variable 5) of the transfer destination rectangular area are (vertical 100, horizontal 40).
0), memory information of transfer destination (variable 6) is second next, coordinates of start point of rectangular area of transfer source (variable 7, variable 8)
Is (0, 0), and the memory information of the transfer source (variable 9) is on air.

This transfer destination information is information for specifying the transfer destination memory and area in the storage means 3, and the transfer source information is information for specifying the transfer source memory and area in the storage means 3. Is. The program control unit 12 outputs the memory information (second next) of the transfer destination and the memory information (on-air) of the transfer source to the screen management unit 10, and further, the corresponding memory number (the transfer destination is M1, the transfer destination) based on the management table. Originally, M2) is output to the transfer means 11.

The program control means 12 also outputs to the transfer means 11 the coordinates of the starting point of the rectangular area of the transfer destination, the vertical and horizontal sizes, and the coordinates of the starting point of the rectangular area of the transfer source. Therefore, the transfer unit 11 uses the coordinate information of the memory (M2) of the transfer source as the starting point and sets the images ((0,0) and (100,400) of the rectangular area having the same size as the transfer destination as the end points of the diagonal line. An image of a rectangular area) is an area of the same size ((0, 0) and (1) starting from the coordinate information of the transfer destination memory (M1).
00, 400) to a rectangular area whose diagonal end points are). In this case, the memory M2 serves both as a transfer source buffer for storing the transfer source still image data and as a memory for switching the screen of the dissolve effect.

Further, after the transfer of the image is finished, the program control means 12 causes the program storage means 8 to transfer the coordinates of the transfer destination, the rectangular size, among the parameters of the rectangular transfer command.
Obtain the increase / decrease value (constant) of the transfer source coordinates. In this case, for example, the transfer destination coordinates are (0, plus 100), the rectangle size is (vertical 0, horizontal 0), and the transfer source coordinates are (0, plus 10).
0).

Then, with respect to the variables storing the coordinates and rectangle size of the transfer destination and the variables storing the coordinates of the transfer source,
Add the increase / decrease value described above. Therefore, the variables (variable 2, variable 3) that store the coordinates of the transfer destination are (0, 100),
Variables that store the rectangle size of the transfer destination (variable 4, variable 5)
Becomes (vertical 100, horizontal 400), and the variables (variable 7, variable 8) for storing the transfer source coordinates are (0, 100).

Next, in the same manner, the program control means 12
Obtains the loop command and the number of loops, which are the parameter (constant), and the label number from the program storage means 8 in item 3. The program control means 12 transfers execution control to the command having the same label number. In this case, it is the rectangular transfer command of item 2.

That is, the value of the program counter 9 is decreased so that the rectangular transfer command of item 2 is designated for the program counter 9. Furthermore, the number of loops is, for example, 11
In the case of the number of times, the number of loops is decreased by 1 to 10 times. Then, the program control means 12 obtains the rectangular transfer command of item 2 from the program storage means 8 according to the program counter 9.

At this time, the variable for storing the transfer destination coordinates is (0, 100), the variable for storing the transfer destination rectangle size (vertical 100, horizontal 400), and the variable for storing the transfer source coordinates ((100)). 0, 100), the image transfer similar to the above is performed based on these, the variable storing the transfer destination memory information (second next), and the variable storing the transfer source memory information (on air). I do. Also,
After transfer, by adding each increase / decrease value to each variable,
The variable is updated.

The loop command of item 3 is executed again,
The transfer command of item 2 and the loop command of item 3 are repeated until the number of loops becomes zero. That is, as a result, on the screen of the monitor 6, a rectangular area of 100 pixels in height and 400 pixels in width is displayed from the upper left end point of the screen by the transfer command.
The images are sequentially transferred in the vertical direction along the left side surface of the screen, and the image on the left side of the screen (400 pixels in width) is overcoated.

Although not shown in the effect program of FIG. 3, the image transfer position is moved to the upper right next to the overpainted area on the screen, and a rectangular area of 100 pixels vertically and 400 pixels horizontally is overpainted. It is described that the effect program is ended when a single vertical column (width of 400 pixels) is transferred one after another along with the full screen transfer. Therefore, the still image data of the memory M2 is vertically and vertically arranged in the memory M1 (width 4
(00 pixels) sequentially, and when all the still image data in the memory M2 is finally transferred to the memory M1, the program control means 12 executes the end command of item N, and the effect program ends.

At this time, since the execution time (16 seconds) of the dissolve effect by the dissolve command is much longer than the time from the start of transfer of one rectangular transfer command to the end of transfer, until the dissolve effect is completed. Many transfer commands can be executed. Therefore, for the still image (still image stored in the memory M1) that sinks due to the dissolve effect on the monitor 6 while the dissolve effect is being realized, the memory M2 that is the transfer source buffer is used.
From this, rectangular images are transferred one after another, and in addition to the dissolve effect, it is clear that the images are transferred one after another on the display screen, and different image effects can be realized.

In the above description, the program control means 1
The operation of No. 2 has been described with reference to the effect program of FIG. 3, but will be described with reference to FIG. 4 showing the flow chart of the program control means 12 and FIG. 5 schematically showing the special image effect. In the initial state designated by the initial state designating means 7, the on-air data is stored in the memory M1 as described above.
, The next is set in the memory M2, and the second next is set in the memory M3.

Furthermore, it is assumed that the effect program of FIG. 3 is designated to be executed, and the designated effect program is stored in the program storage means 8.
Further, the memory M1 previously stores still image data schematically showing mountains and clouds as shown in FIG.
It is assumed that the memory M2 stores still image data that schematically represents two trees.

Therefore, the still images of mountains and clouds are displayed on the monitor 6, and the screen can be switched to the still images of two trees by switching the images accompanied by the special image effect described below. Done Referring to FIG. 4, step S1
When the line is designated by the program counter 9 as shown in, the program control means 12 determines whether the command of the designated line is a composite command as shown in step S2.

In this case, since the designated dissolve command of item 1 is a composite command, the process proceeds to step S3. In step S3, it is determined whether or not a value is set in the variable for the composite command. If it is determined that the value has not been set, the process proceeds to step S4 and the initial value is set in the variable.

In this case, since the initial value has not been set in the variable corresponding to the dissolve command, the initial value is set in step S4. Specifically, the program control means 12 obtains from the program storage means 8 a variable 1 for storing the effect execution time which is a parameter of the dissolve command. Further, the effect execution time (for example, 16 seconds) is obtained by referring to the variable initial value part, and this is set in the variable 1.

Next, in step S5, the combined distribution is output. Since the effect execution time is selected from predetermined candidates, the program control means 12 is based on a combining table in which the effect time is associated with the composition distribution for the on-air memory and the next memory. Calculates the composite allocation required to dissolve for 16 seconds, and outputs the obtained composite allocation information to the combining means 4.

Further, in step S6, the program control means 12 outputs information indicating a command for composition to the screen management means 10, and causes the composition means 4 to output the on-air memory number M1 and the next memory number M2. . Therefore, the synthesizing unit 4 starts synthesizing the still image data to perform the dissolve effect from the on-air (memory M1) to the next (memory M2).

Along with this, the screen management means 10 updates the management table in step S7. As a result, the on-air becomes the memory M2, the next becomes the memory M3, and the second next becomes the memory M1. Next, as shown in step S8, the program control means 12 instructs the program counter 9 to update the value of the program counter, and adds "1" to the value of the program counter. Then, the process returns to step S1.

Next, in step S1, the program counter 9 specifies the rectangular transfer command of item 2. Since the rectangular transfer command is not a command for composition, the process moves from step S2 to step S9. Step S
At 9, it is determined whether the command in the designated line is a transfer command. In this case, the rectangle transfer command is
Since it is a transfer command, the process proceeds to step S10.

In step S10, it is determined whether a value has already been set in the variable corresponding to the rectangular transfer command. If a value has not been set in this variable, the process proceeds to step S11, and an initial value is set in this variable. In this case, since the initial value has not yet been set in the variable, the initial value is set in step S11.

Specifically, the program control means 12
From the program storage means 8, parameters of a rectangular transfer command, that is, transfer source information including coordinates of a starting point of a transfer destination rectangular area and memory information, and transfer source information including coordinates of a starting point of a transfer source rectangular area and memory information. Get the variables that store and. Furthermore, the initial values for setting these variables are obtained by referring to the variable initial value part. Then, this initial value is set in the variable.

For example, the coordinates of the starting point (variable 2, variable 3) of the transfer destination rectangular area are (0, 0), and the vertical and horizontal sizes (variable 4, variable 5) of the transfer destination rectangular area are (vertical 100, horizontal 40).
0), memory information of transfer destination (variable 6) is second next, coordinates of start point of rectangular area of transfer source (variable 7, variable 8)
Is (0, 0), and the memory information of the transfer source (variable 9) is on air.

Further, in step S12, the program control means 12 outputs the transfer destination memory information (second next) and the transfer source memory information (on air) to the screen management means 10. Further, based on the management table, the corresponding memory number (transfer destination is M1, transfer source is M2) is output to the transfer means 11. Also, the program control means 12
Outputs to the transfer means 11 the coordinates of the start point of the transfer destination rectangular area, the vertical and horizontal sizes, and the coordinates of the start point of the transfer source rectangular area.

In accordance with this, as shown in step S13, the transfer means 11 transfers the still image data. The transfer unit 11 uses the coordinate information of the memory (M2) of the transfer source as a start point, and a rectangle in which the images ((0,0) and (100,400)) in the area of the same rectangular size as the transfer destination are diagonal endpoints. The image of the area is an area ((0,0) and (1) of the same size starting from the coordinate information of the transfer destination memory (M1).
00, 400) to a rectangular area whose diagonal end points are).

In this case, the memory M2 serves as a transfer source buffer for accumulating still image data of the transfer source and a memory for storing the image to be displayed by switching the screen by switching the screen of the dissolve effect. Is also used as. After the transfer of such still image data is completed, as shown in step S14, the program control unit 12 causes the program storage unit 8 to transfer the coordinates of the transfer destination, the rectangular size, among the parameters of the rectangular transfer command.
Obtain the increase / decrease value (constant) of the transfer source coordinates.

In this case, for example, the coordinates of the transfer destination are (0,
+100), the rectangular size is (vertical 0, horizontal 0), and the transfer source coordinates are (0, +100). Further, as shown in step S15, the program control means 12
Adds the above-mentioned increase / decrease value to each of the variable storing the coordinates and the rectangle size of the transfer destination and the variable storing the coordinates of the transfer source.

Therefore, the variables are as follows. The variables (variable 2, variable 3) that store the coordinates of the transfer destination are (0, 1
00). The variables (variable 4, variable 5) for storing the transfer destination rectangle size are (vertical 100, horizontal 400). The variables (variable 7, variable 8) that store the coordinates of the transfer source are
It becomes (0, 100). Next, in step S16, "1" is added to the value of the program counter 9. As a result, the processing returns to step S1, and the processing target shifts to the loop command of item 3.

Thereafter, the process proceeds to step S17 via steps S2 and S9. In step S17, it is determined whether or not the command designated by the program counter 9 is a loop command. If it is determined that the command is a loop command, the process proceeds to step S18. In this case, the process is step S18.
Move to.

Thereafter, the program control means 12 goes through steps S18, S19 and S20,
Again, the processing is shifted to step S1. At this time, the program control means 12 shifts the processing to the command having the same label number (L1). In this case, the transfer destination is the transfer command of item 2. In addition, in step S18 described above, processing for reducing the number of loops by one is performed. In step S19, it is determined whether the number of loops is equal to "0".

As a result, if the number of loops is not equal to "0", the process proceeds to step S20, and the value of the program counter 9 is set so that the program counter 9 specifies the rectangular transfer command of item 2. When the loop command returns the process to the rectangular transfer command again, the following process is performed.

After steps S2 and S9, the process proceeds to step S10. In step S10, since the variable which is the parameter of the rectangular transfer command has already been set to a value, the process proceeds to step S12. Specifically, the variable that stores the coordinates of the transfer destination is (0, 100),
The variable that stores the rectangle size of the transfer destination is (vertical 100, horizontal 4
00), the variable that stores the transfer source coordinates is (0, 100)
Is set to.

Based on these variables, the variable storing the transfer destination memory information (second next), and the variable storing the transfer source memory information (on air), step S1
At 3, the same image transfer as described above is performed. After the transfer, the variable is updated by adding each increase / decrease value to each variable (step S14, step S1).
5).

In step S16, the program counter 9 again points to the loop command of item 3, and as shown in step S19, the transfer command of item 2 and the loop of item 3 are looped until the loop count becomes "0". Command and repeat. When the number of loops becomes equal to "0", the process proceeds to step S21, and 1 is added to the value of the program counter 9 in step S21.

This completes the processing according to the loop command. By repeating the rectangular transfer command of item 2 and the loop command of item 3 in this way, the following display state occurs on the screen of the monitor 6. That is, in the still image data of the two trees stored in the memory M2 by the transfer command, a rectangular area of 100 pixels vertically and 400 pixels horizontally starting from the upper left endpoint is stored in the memory M1. And are transferred to the same position in the still image data of the cloud.

By repeating the rectangular transfer while shifting the rectangular position of the transfer source and the rectangular position of the transfer destination along the left side surface downward by 100 pixels for each transfer, one line on the left side of the memory M1 (width of 400 pixels). ) Image is the memory M
The image on the left side of the second row (400 pixels in width) is overcoated. Therefore, the image in the state of FIG. 5B is displayed on the monitor 6.

Further, although not shown in the effect program of FIG. 3, this effect program moves the image transfer position to the upper right next to the overpainted area on the screen, and similarly 100 pixels vertically and 400 pixels horizontally. Transfer rectangular areas of pixels one after another along the overpainted area. By repeating this, one vertical column (400 pixels in width) is sequentially transferred to the right side. Therefore, as shown in FIG. 5, the images displayed on the monitor 6 are (b), (c), (d),
It changes from (e).

Then, as a result of the transfer, as shown in FIG. 5F, when the entire screen is transferred, the process proceeds to step S22.
Then, the program control means 12 executes the end command of item N, thereby ending the effect program. Therefore, the still image that schematically shows the displayed mountains and clouds is submerged by the dissolve effect, and
While the still image schematically showing the tree of trees is being emerged, the still image data is transferred so that the still image schematically showing the two trees is gradually and clearly displayed from the left side of the screen. Special image effects can be realized.

In addition to this, since such a special image effect can be realized by performing the dissolve effect and the image transfer in parallel, it can be realized without changing the hardware. Therefore, it is possible to prevent the cost of the heart wear for realizing such a special image effect from increasing. Whether the still image data in the memory M1 is switched to the still image data in the memory M2 by the dissolve effect (16 seconds),
Whether all of the still image data in the memory M2 is transferred to the memory M1 by image transfer or which is performed earlier in time depends on the effect program and is not unique, but needless to say it is not necessarily limited to this. .

In the above-described embodiment, the case where the composite command such as the dissolve command is executed only once has been described. However, for example, it may be executed twice in succession. In that case, the program control means may be used. The control unit 12 controls so that execution of the next compositing command is kept waiting until the information indicating that the execution of the compositing command is completed is received from the composing means 4. Furthermore, when the above-mentioned end command of item N is designated for execution, if the synthesizing means 4 is still performing the synthesizing processing such as dissolve, the program control means 12 ends the synthesizing processing. The execution of the command is waited, and the end command is controlled after the execution of the combining process is completed.

In the above-described embodiment, the entire area of the screen is overpainted by transferring the image of the rectangular area to the entire memory of one frame of the transfer destination. However, the present invention is not limited to this. The coordinates of the start point of the rectangular area are fixed, and the coordinates of the start point of the transfer source rectangular area are moved by a few pixels each time the transfer is performed. A part of the still image may be rolled so that it can be seen, and this may be controlled so that dissolve and wipe are executed at the same time.

The transfer of the image is not limited to the rectangular area, and a vertical line is drawn from the transfer source memory (what is M1, M2, M3) to the transfer destination memory (what is M1, M2, M3). Minute 1
A book or one line segment in the horizontal direction may be transferred every time. Furthermore, in the above-mentioned effect program, the transfer destination information and the transfer source information of the image are specified as the parameters of the rectangular transfer command. However, if a part (or all) of the transfer destination information and the transfer source information are the same, The parameter may be specified by omitting the part (or all) of either one of the information. For example, when the start point coordinates of the transfer destination and the start point coordinates of the transfer source are the same, the start point coordinates of the transfer source are omitted and parameters are designated. At this time, the program control means 12 interprets that the start point information of the transfer destination specified by the parameter is also designated as the start point information of the transfer source.

In this embodiment, a special image effect is realized by transferring images in parallel while the dissolve effect is being executed. However, the present invention is not limited to this, and, for example, a wipe effect may be applied. Images may be transferred in parallel during execution, or in parallel during roll effect execution.
Needless to say, the image may be transferred.

Further, in this embodiment, the two memories (M1, M2) of the transfer destination and the transfer source by the transfer means and the two memories (M1, M2) switched by the combining means are provided.
It was described as the same. However, the present application is not limited to this. For example, if the memory (M3) is replaced by the memory (M
If the same image as in 2) is stored, the two memories of the transfer destination and the transfer source by the transfer means may be (M1, M3), and the two memories switched by the combining means may be (M1, M2). Is displayed. The point is that the transfer process and the combining process may be performed at the same time.

The above-mentioned embodiments are merely examples of the present invention, and various modifications can be made if necessary. The present invention described in the claims includes all those modifications. Is. Further, it is needless to say that the functional blocks of the above-described embodiments may be configured by software or hardware as necessary, and the present invention includes some aspect.
