【Example】

Example 1. A first embodiment of the present invention will be described. Figure 1
FIG. 2 is a diagram showing a configuration of a data reproducing apparatus according to a first embodiment of the present invention.

It is determined which position of the function button of the menu displayed on the screen of No. 5 is designated by the designating means 1, and when the function is executed, which function is executed based on the position of the designated function button. It is a designated function operation determination means for determining whether or not it is designated. The position detecting means 2, the processing means 4, the time measuring means 6,
The screen movement speed calculation means 7 and the designated function operation determination means 8 are
It is composed of a processor that constitutes a computer system and software or hardware devices that operate on the processor.

The procedure for setting the screen movement speed in the data reproducing apparatus configured as described above will be described with reference to FIG. Similar to the conventional example, for example, in the state where moving image data is being reproduced, the display screen of the display unit 5 is displayed as shown in FIG.
The moving image data and the operation menu as shown in are displayed in the respective display areas. At this time, the user can use the specifying means 1 to specify an arbitrary point on the display screen and select a function from the displayed operation menu, as in the conventional device. When the user wants to change the screen reproduction speed setting, the user inputs a command indicating that the screen reproduction speed is to be set from the designating means 1, and the data reproducing apparatus enters the screen reproduction speed setting mode. Then, the state in which the position is explicitly designated with respect to the data reproducing device by the designating means 1-for example, when the designating means 1 is a tablet as shown in FIG. For example, when the position is aligned and the click button of the mouse is pressed, the length of the specified point moved on the display screen is defined as the stroke amount that is the basis of the screen playback speed setting. At this time, the area defining the stroke amount may be an arbitrary area on the display screen, or a specific setting area may be provided on the display screen for defining the stroke.

When the user starts the operation of defining the stroke amount using the designating means 1, the position detecting means 2 causes the position coordinates (x, x, x) at each designated point in the middle of the stroke as shown in FIG.
y) is sequentially detected and transmitted to the screen movement speed calculation means 7, and at the same time, the time counting means 6 starts measuring the time t ₁ required for this stroke. Then, the definition of the stroke amount ends. For example, when the designating means 1 is a tablet, when the tip of the pen is released from the tablet, when it is a mouse, when the mouse is aligned and the click button of the mouse is released- The means 6 terminates the measurement of the time t ₁ required for this stroke and informs the screen movement speed calculation means 7 of the time t ₁ . The screen movement speed calculation means 7 sequentially calculates the movement distance between the designated points in this stroke from the position coordinates (x, y) of the designated points obtained from the position detection means 2 as shown in FIG. The total moving distance L is shown in FIG.
Calculate as. Then, the screen moving speed v is calculated from the moving time t ₁ measured by the time measuring means 6 as follows. v = L / t ₁ Therefore, when reproducing moving image data thereafter,
The speed v is used as the reproduction speed.

The information of the defined speed v is stored in the memory of the screen moving speed calculating means 7 itself and sent to the designated function operation judging means 8. Based on the quantitative speed information, the designated function operation determination means 8 sets the reproduction speed of the moving image data to v, and the processing means 4 uses that speed for the subsequent reproduction processing of the moving image data. Specifies to play moving image data. According to the designation, the processing means 4 performs the reproduction process of the image data moving at the speed until a new speed is set. As described above, according to the first embodiment, it is possible to match the user's preference with the user's hand without complicating the speed of moving the screen to a constant level for data reproduction, fast-forwarding, rewinding, or the like. It is possible to reproduce image data that moves depending on the reproduction speed.

In the above embodiment, the setting of the reproduction speed in the reproduction processing is described. However, also in the setting of the screen movement speed in the fast forward and rewind processing, a predetermined screen movement speed setting command is input in each mode. By setting the screen moving speed, it is possible to set the screen moving speed in each process similarly to the setting of the reproducing speed in the reproducing process.

Further, when the reproduction speed of the processing means 4 cannot specify any speed infinitely, as shown in FIG. 6, the speed information defined by the specified function operation determination means 8 and the processing means 4 are set. It is also possible to previously create a correspondence table with the reproduction speed and to determine the reproduction speed in the processing means 4 step by step.

Further, as shown in FIG. 7, the total moving distance L in the screen moving speed calculating means 7 may be simply calculated so as to be a linear distance between the start point and the end point of the stroke.

Further, as shown in FIG. 8, in the screen moving speed calculating means 7, a measuring time t in the time measuring means 6 is measured.
_It is also possible to limit the number to ₂ and define the moving speed per measurement time t ₂ as the total moving distance L, the reproduction speed of moving image data is v, the moving amount of one stroke is L, and the set speed to be defined.

In this embodiment, the processing means 4 has been described as a data reproducing apparatus having functions such as reproduction of moving image data, fast-forwarding, and pause, but the type of operation in the designated function operation judging means 8 is made variable. Thus, the processing means 4 uses a processing device that uses a quantitative speed value, for example, a sound reproducing device (which can change the sound reproducing speed) or a screen scrolling device (a scroll reproducing expansion of a still image such as a map). The moving speed can be changed).

Example 2. A second embodiment of the present invention will be described. FIG. 9 is a block diagram of a data reproducing apparatus according to the second embodiment, in which the same or corresponding parts as those in the conventional example and the above-mentioned example are designated by the same reference numerals and the description thereof is omitted. Figure 9
In the reference numeral 9, 9 determines the speed for moving the screen based on the position information from the position detecting means 2 and the time information from the time measuring means 3 and stores it in its own memory, and also moves the currently set screen. It is a screen moving speed determination means for calculating to what extent the speed is changed (relative speed change). The position detecting means 2, the processing means 4, the time measuring means 6,
The screen movement speed determination means 9 and the designated function operation determination means 8 are
It is composed of a processor that constitutes a computer system and software or hardware devices that operate on the processor.

The procedure for setting the screen moving speed in the data reproducing apparatus configured as described above will be described with reference to FIG. As in the case of the conventional example, when moving image data is being reproduced, the display means 5 is displayed in the same manner as in the example described above.
A screen of moving image data and an operation menu as shown in are displayed in respective areas. At this time, the user can use the specifying means 1 to specify an arbitrary point on the screen and select a function from the displayed operation menu, as in the conventional device. When the user wants to change the screen reproduction speed setting, the user inputs a command indicating that the screen reproduction speed is to be set from the designating means 1, and the data reproducing apparatus enters the screen reproduction speed setting mode. When the user starts the stroke amount defining operation using the designating means 1, the position detecting means 2 sequentially detects the position coordinates (x, y) at each designated point in the middle of the stroke, as in the first embodiment. While notifying the screen moving speed determining means 7, the time measuring means 6 starts measuring the time t ₁ 'required for the stroke. Then, the definition of the stroke amount is completed. For example, as shown in FIG. 3 of the first embodiment, if the designating means 1 is a tablet, the pen tip is attached to the tablet. The length of movement of the position of the designated point on the screen while the click button is pressed is defined as the movement amount L ′ in this stroke.
The area for defining the stroke may be an arbitrary area on the screen, or a specific area may be provided on the screen for defining the stroke.

When the user starts the operation of defining the stroke amount by using the designating means 1, the position detecting means 2 causes the position coordinates (x, x at each designated point in the stroke as shown in FIG.
y) is sequentially detected and transmitted to the screen movement speed determination means 7, and at the same time, the time counting means 6 starts measuring the time t ₁ 'required for this stroke. Then, the definition of the stroke amount ends. For example, when the designating means 1 is a tablet, when the tip of the pen is released from the tablet, when it is a mouse, when the mouse is aligned and the click button of the mouse is released- The means 6 completes the measurement of the time t ₁ 'required for this stroke and notifies the time t ₁ ' to the screen movement speed determination means 9. As shown in FIG. 4, the screen moving speed determining means 9 sequentially calculates the moving distance between the designated points in this stroke from the position coordinates (x, y) of the designated points obtained from the position detecting means 2, New movement amount L '
To calculate. Then, the moving speed v'is determined by the moving time t ₁ 'measured by the time measuring means 6 as follows. v ′ = L ′ / t ₁ ′ Then, the screen moving speed determination means 9 sets the currently set moving speed v (which is already stored in the memory when the moving speed is determined) and the calculated moving speed v ′. Then, the speed difference Δv of the moving speed is calculated as follows. Δv = v′−v This moving speed v ′ is stored in the memory of the screen moving speed calculating means 7 itself, and the information of the moving speed difference Δv is sent to the designated function operation determining means 8. Based on the quantitative speed information, the designated function operation determination means 8 sets the reproduction speed of the moving image data as v + Δv, and the processing means 4 uses this speed for the subsequent reproduction processing of the moving image data. Specifies to play moving image data. According to the designation, the processing means 4 performs the reproduction process of the image data moving at the speed until a new speed is set. In this way, by correcting the moving distance of the current stroke and the reproduction speed, the speed v ′ is used as the reproduction speed when reproducing moving image data thereafter.

As described above, according to the second embodiment, it is possible for the user to have his / her preference without the trouble of adjusting the moving speed of the screen at a constant speed by playing back, fast-forwarding, and rewinding the data. It is possible to reproduce moving image data at a reproduction speed adapted to.

In the above embodiment, the setting of the reproduction speed in the reproduction processing is described. However, also in the setting of the screen movement speed in the fast forward and rewind processing, a predetermined screen movement speed setting command is input in each mode. By setting the screen moving speed, it is possible to set the screen moving speed in each process similarly to the setting of the reproducing speed in the reproducing process.

Further, as shown in FIG. 9, 'as long as the, the measured time t _2' measurement time t ₂ with the clock means 6 moving distance per a moving distance L, moving images on the screen moving speed calculator 7 Alternatively, v ′ may be obtained as a change in the speed of data reproduction.

In this embodiment, the processing means 4 has been described as a data reproducing apparatus having functions of reproducing moving image data, fast-forwarding, pausing, etc., but the kind of operation in the designated function operation judging means 8 is made variable. Therefore, the processing means 4
A data processing device that uses a quantitative speed value, such as a sound reproduction device (the sound reproduction speed can be changed),
It can be applied to a screen scroll device (which can change the moving speed of scroll reproduction development of a still image such as a map).

Example 3. A third embodiment of the present invention will be described. 10 is a diagram showing a configuration of a data reproducing apparatus according to a third embodiment of the present invention. In FIG. 10, the same or corresponding components as those of the conventional example and the example are designated by the same reference numerals. The description is omitted. In FIG. 10, 10 is a reproduction movement direction determining means for detecting the reproduction movement direction from the change in the position coordinates output from the position detection means 2, 11 is position information of the position detection means 2, screen movement speed calculation means 7 Of the function button of the menu displayed on the screen of the display unit 5 is determined based on the moving speed information of the display unit and the moving direction information of the reproduction moving direction determination unit 10, and the function is executed. In this case, the operation control means determines which function is specified to be executed based on the specified position. The position detecting means 2, the processing means 4, the time counting means 6, the screen moving speed calculating means 7, the reproduction moving direction determining means 10, and the operation control means 11 are a processor constituting the computer system and software operating thereon, or , Is realized by a hardware device.

The procedure for setting the screen moving speed in the data reproducing apparatus configured as described above will be described with reference to FIG. Similar to the conventional example, when moving image data is being reproduced, the display unit 5 displays a moving image data screen and an operation menu as shown in FIG. 2 in respective areas. At this time, the user can use the specifying means 1 to specify an arbitrary point on the display screen and select a function from the displayed operation menu, as in the conventional device. If the user wants to change the screen reproduction speed, the user inputs a command indicating that the screen reproduction speed is to be set from the designating means 1, and the data reproducing apparatus enters the screen reproduction speed setting mode. Then, the state in which the position is explicitly designated with respect to the data reproducing device by the designating means 1-for example, when the designating means 1 is a tablet as shown in FIG. For example, when the position is aligned and the click button of the mouse is pressed, the length of the specified point moved on the display screen is defined as the stroke amount that is the basis of the screen playback speed setting. At this time, the area defining the stroke amount may be an arbitrary area on the display screen, or a specific area may be provided on the display screen for defining the stroke.

When the user starts the stroke amount defining operation using the designating means 1, the position detecting means 2 detects the position coordinates (x, y) at each designated point in the stroke, as shown in FIG. To the screen movement speed calculation means 7, the reproduction movement direction determination means 10 and the operation control means 11, and the timing means 6 starts measuring the time t ₁ required for this stroke. Then, the definition of this stroke amount ends-for example,
If the designating means 1 is a tablet, when the tip of the pen is released from the tablet, and if it is a mouse, when the mouse is aligned and the click button of the mouse is released-then, the timekeeping means 6 takes the time t ₂ required for this stroke. After the measurement is completed, the time t ₂ is transmitted to the screen moving speed calculation means 7. The screen movement speed calculation means 7 sequentially calculates the movement distance between the designated points in this stroke from the position coordinates (x, y) of the designated points obtained from the position detecting means 2 as shown in FIG.
The total moving distance L is calculated. Then, the moving speed v of the screen is calculated from the moving time t ₂ measured by the time measuring means 6 as described below, as in the first embodiment. v = L / t ₂ Therefore, when reproducing moving image data thereafter,
The speed v is used as the reproduction speed.

The information on the defined speed v is stored in the memory of the screen moving speed calculating means 7 itself and sent to the operation control means 11. The operation control means 11 sets the reproduction speed of the moving image data to v based on the quantitative speed information, and the processing means 4 moves at that speed for the subsequent processing of the reproducing function of the moving image data. Specifies to play the image data.

On the other hand, regarding the moving speed, the moving direction becomes a problem, and the reproducing moving direction determining means 10 determines the moving direction based on the position information of each designated point from the position detecting means 2. For example, with respect to the reference point (for example, the start point), if the moving direction of the designated point is on the right side of the start point on the display screen, it may be assigned as positive scroll movement, and if it is on the left side of the start point, negative scroll movement may be assigned. In the present embodiment, the reproduction direction is determined as follows. As shown in FIG. 11, the reproduction movement direction determining means 10 calculates the direction vector r from each start point coordinate and each end point coordinate of the stroke. Then, as shown in FIG. 12, the reproduction moving direction determining means 10 determines that the normal moving direction is normal reproduction when the x coordinate component of the direction vector r is positive, and the reverse moving direction when the x coordinate component is negative. To decide. Reproduction moving direction determining means 10
The movement direction determined by is transmitted to the operation control means 11. The operation control means 11 instructs the processing means 4 to reproduce the moving image data in the moving direction for the subsequent processing of the moving image data reproducing function. In accordance with these designations, the processing means 4 performs reproduction processing of image data that moves based on the moving direction and the moving speed until a new moving direction is defined. As described above, according to the third embodiment, it is possible to match the user's preference with the user's hand without complicating the speed of moving the screen at a constant speed such as data reproduction, fast-forwarding, and rewinding. It is possible to reproduce image data that moves depending on the reproduction speed and the reproduction direction.

In the above embodiment, the setting of the reproduction speed in the reproduction processing is described. However, also in the setting of the screen movement speed in the fast forward and rewind processing, a command for setting a predetermined screen movement speed is input in each mode. By setting the screen moving speed in this way, the screen moving speed in each process can be set similarly to the setting of the reproducing speed in the reproducing process.

In this embodiment, the processing means 4 is described as a data reproducing apparatus having functions of reproducing moving image data, fast-forwarding, pausing, etc. However, by changing the type of operation in the operation control means 11. The processing means 4 may be used in a processing device that uses a quantitative velocity value or direction, such as a voice reproduction device or a screen scroll device.

Further, the reproduction moving direction determining means 10 is shown in FIG.
As shown in FIG. 3, the screen moving speed calculating means 7 may be incorporated and the position information from the position detecting means 2 may be shared and processed.

Further, as shown in FIG. 8, in the screen moving speed calculating means 7, a measuring time t _{2 in the} time measuring means 6 is measured.
And the moving distance per the measurement time t ₂ is set as the total moving distance L, and the reproducing speed of moving image data is calculated by v,
It may be defined.

₂ is divided and each direction vector r _i is simply obtained from each start point coordinate and each end point coordinate at each measurement time t ₂ .
The direction vector r may be defined from the sum of the respective direction vectors r _i .

At this time, the user can use the specifying means 1 to specify an arbitrary point on the screen and select a function from the displayed operation menu, as in the conventional device. If the user wants to change the screen reproduction speed, the user inputs a command indicating that the screen reproduction speed is to be defined from the designating means 1, and the data reproducing apparatus enters the screen reproduction speed setting mode. And
A state in which the position is explicitly designated with respect to the data reproducing device by the designating unit 1-for example, when the designating unit 1 is a tablet as shown in FIG. With the mouse click button pressed, the length of the designated point moved on the display screen is defined as the stroke amount that is the basis of the screen playback speed setting. At this time, the area defining the stroke amount may be an arbitrary area on the display screen, or a specific area may be provided on the display screen for defining the stroke.

When the user starts the stroke amount defining operation using the designating means 1, the position detecting means 2 causes the position coordinates (x, x, x) at each designated point in the stroke as shown in FIG.
y) is sequentially detected and started to be transmitted to the screen moving speed determining means 7, and the time measuring means 6 starts measuring the time t ₂ 'required for this stroke. Then, the definition of the stroke amount ends. For example, when the designating means 1 is a tablet, when the tip of the pen is released from the tablet, when it is a mouse, when the mouse is aligned and the click button of the mouse is released- The means 6 completes the measurement of the time t ₂ 'required for this stroke and informs the screen movement speed determination means 9 of the time t ₂ '. As shown in FIG. 4, the screen moving speed determining means 9 sequentially calculates the moving distance between the designated points in this stroke from the position coordinates (x, y) of the designated points obtained from the position detecting means 2, New movement amount L '
To calculate. Then, 'This movement velocity v' traveling time measured by the time measuring means 6 t ₂ determines the as follows. v ′ = L ′ / t ₂ ′ Then, the screen moving speed determination means 9 sets the currently set moving speed v (which is already stored in the memory when the moving speed is determined) and the calculated moving speed v ′. Then, the speed difference Δv of the moving speed is calculated as follows. Δv = v′−v This moving speed v ′ is stored in the memory of the screen moving speed calculating means 7 itself, and the information of the moving speed difference Δv is sent to the operation control means 11. Operation control means 11
Then, the reproduction speed of the moving image data is set to v + Δv based on the quantitative speed information, and for the subsequent reproduction processing of the moving image data, the processing means 4 is made to reproduce the image data moving at this speed. Specify to do. According to the designation, the processing means 4 performs the reproduction process of the image data moving at the speed until a new speed is set. In this way, by correcting the moving distance of the current stroke and the reproduction speed, the speed v + Δv is used as the reproduction speed when reproducing the moving image data thereafter.

On the other hand, regarding the moving speed and the moving amount, the moving direction becomes a problem. The reproducing moving direction determining means 10 determines the moving direction based on the position information of each designated point from the position detecting means 2. For example, for a reference point (for example, the starting point),
If the moving direction of the designated point is on the right side of the starting point on the display screen, the scrolling movement in the positive direction may be allocated, and if it is on the left side of the starting point, the scrolling movement in the negative direction may be allocated. In the present embodiment, the reproduction direction is determined as follows. As shown in FIG. 11, the reproduction movement direction determining means 10 calculates the direction vector r from the starting point coordinates and the ending point coordinates of the stroke. The reproduction moving direction determining means 10 is shown in FIG.
As shown in 2, the moving direction of reproduction is defined as normal reproduction in the positive direction if the x coordinate component of the direction vector r is positive, and reproduction in the reverse direction if the x coordinate component is negative. The movement direction determined by the reproduction movement direction determination means 10 is transmitted to the operation control means 11. The operation control means 8 instructs the processing means 4 to perform reproduction in this moving direction for the subsequent processing of the reproduction function of moving image data. According to the designation, the processing means 4 performs the reproduction process of the image data that moves based on the moving direction until the next new moving direction is defined. As described above, according to the fourth embodiment, the user's hand can meet the user's preference without the complexity of adjusting the speed of moving the screen to a constant value for data reproduction, fast-forwarding, rewinding, or the like. It is possible to reproduce image data that moves depending on the reproduction speed and the reproduction direction.

In this embodiment, the processing means 4 has been described as a data reproducing apparatus having functions of reproducing moving image data, fast-forwarding, pausing, etc., but the type of operation in the designated function operation judging means 8 is made variable. Therefore, the processing means 4
A data processing device that uses a quantitative speed value, such as a sound reproduction device (the sound reproduction speed can be changed),
It can be applied to a screen scroll device (which can change the moving speed of scroll reproduction development of a still image such as a map).

Further, the reproducing movement direction determining means 10 is shown in FIG.
As shown in FIG. 3, the screen moving speed calculating means 7 may be incorporated and the position information from the position detecting means 2 may be shared and processed.

Further, as shown in FIG. 8, in the screen moving speed calculating means 7, a measuring time t _{2 in the} time measuring means 6
The moving speed per measurement time t ₂ may be defined as the total moving distance L, and the reproduction speed v of moving image data may be obtained and defined.

Further, as shown in FIG. 13, in the reproduction moving direction determining means 7, a certain measuring time t in the time measuring means 6 is measured.
', Separated, each measured time t _{2' 2} obtains the respective direction vectors r _i in a simplified manner from the starting point and end point in, be define the direction vector r from the sum of each direction vector r _i in the measurement time Good.
