Abstract

PURPOSE:To reduce th circuit scale of the printer by outputting a preset conversion address corresponding to a readout address based on the mode selected from a storage means storing print mode control information such as erected picture, reversed picture, split picture and magnified picture of a frame picture. CONSTITUTION:When a vertical address counter 14 outputs a readout vertical address in order from '1', for example, 1 is outputted as an initial readout vertical address from a horizontal address counter 16 and readout address changes as 11,21,...,81. When the counter 14 counts 8, a countup signal is fed from the counter 14 to the counter 16 and the counter 16 outputs '2'. Then the read address changes as 12,22,...,82. When the readout address is inputted to the frame memory 2 in this way, the frame memory 2 outputs a picture data corresponding to the readout addresses 11-88 and the picture data is printed out and an erected picture is obtained.

This relates to a printer device that allows you to arbitrarily select printing modes such as reverse image, 90° rotated image, reduced image, enlarged image, etc.

[Prior Art] Printers that print out video based on data on a video screen are conventionally known. A printer device capable of printing out an erect image and a 909 rotated image has been proposed (see Japanese Patent Application Laid-Open No. 63-45984).

[Problems to be Solved by the Invention] By the way, in the conventional example described in the above-mentioned Japanese Patent Application Laid-Open No. 63-45984, only an erect image and a 90° rotated image of the frame image can be printed out. For people, the frame picture is an upright picture, an inverted picture, a split picture,
We have devised a printer device that can print out horizontally reversed images, 90° rotated images, reduced images, enlarged images, etc.

As shown in FIG. 15, this printer device 1 has a frame memory 2 including first and second fields for storing video screen data, and a multiplexer 3 and a multiplexer 4 are connected to the frame memory 2. has been done.

A horizontal up/down counter 5 is connected to the multiplexer 3 for counting by inputting a clock for reading data stored in the frame memory 2 and outputting a horizontal address. The B input of multiplexer 3 has horizontal direction u.
Vertical up/down counter 6 which inputs and counts the count up signal of the up/down counter 5 and outputs a vertical address.
is connected.

Also, the A input of multiplexer 4 has horizontal direction up/down.
A down counter 6 is connected, and a horizontal up/down counter 5 is connected to the B input of the multiplexer 4.

Furthermore, the horizontal direction up/down counter 5
A frequency divider 7 that divides the frequency of the read clock and a left/right inversion key 8 that instructs left/right inversion are connected to the frequency divider 7.
A division instruction key 9 is connected to the , and a read clock is input thereto.

An upright/inverted key 10 for instructing upright/inverted is connected to the vertical up/down counter 6, and a rotation instruction key 11 for instructing rotation to the multiplexers 3 and 4. It is connected.

Next, the operation will be explained.

For example, when obtaining a royal image of 8×8 pixels, the operator selects the upright mode using the upright/inverted key 10.

The read clock passes through the frequency divider 7 in the horizontal direction up
/d o w n is input to the counter 5, and the count value is output as a read address.

At this time, the vertical up/down counter 6 outputs 1 as the initial read address until there is a count up signal from the horizontal up/down counter 5, and the count value is updated as the counter 5 counts up. and output the read address.

Both read addresses are input to the A inputs of multiplexers 3 and 4, and output to the frame memory 2 from the Y outputs.

Therefore, the frame memory 2 can output data corresponding to the read address.

For example, when the horizontal up/down counter 5 sequentially outputs read horizontal addresses starting from 1, the vertical up/down counter 6 outputs 1 as the initial read vertical address. The read address is as shown in FIGS. 16 and 17.
It changes as 11 12 13, 14, 15, 1617.18.

Then, when the horizontal up/down counter 5 or 8 counts, a power count up signal is sent from the horizontal up/down counter 5 to the vertical up/down counter 6, and the vertical up/down counter 5 is counted. d
The o w n counter 6 outputs 2, and the read address is 21, 22, 23, 24, 22.2627.28
and changes.

In this way, the read address is set to frame memory 2.
When the frame memory 2 inputs image data corresponding to read addresses 11 to 88, the image data is printed out by a printing mechanism to obtain an erect image.

Further, when obtaining an inverted image, the operator selects an inverted mode using the upright/inverted key 10.

Then, when the horizontal up/down counter 5 sequentially outputs read horizontal addresses starting from 1, the vertical up/down counter 6 outputs 8 as the previous final read vertical address. The read address is 81.82, 83, 84, 85°86.87.88 as shown in Fig. 16 and Fig. 18.
and changes.

Then, when the horizontal up/down counter 5 or 8 counts, a countdown signal is sent from the horizontal up/down counter 5 to the vertical up/down counter 6, and the vertical up/down counter 5 is counted. /do
The wn counter 6 outputs 7, and the read address is 7.
It changes as 1, 72, 73, 74, 75, 76°7778.

Similarly, when all read addresses are input to the frame memory 2, the frame memory 2 outputs image data corresponding to read addresses 88 to 11, and the image data is printed out by the printing mechanism to obtain an inverted image. .

Further, when obtaining a horizontally reversed image, the operator selects a reverse mode using the horizontally reverse key 8.

Then, the read clock is sequentially read from 1 in the horizontal direction up
When the up/down counter 5 receives the input, the horizontal up/down counter 5 counts down and outputs the read horizontal address sequentially from 8 to 1. At this time, vertical direction up/down
The n counter 6 outputs 1 as the reading vertical address, and the reading address is as shown in Fig. 11 and 1.
As shown in Figure 9, 18.17,16°15.14,1

When the horizontal up/down counter 5 counts 1, the horizontal up/down counter 5 counts 1.
w n Vertical direction up/d o from counter 5
A countdown signal is sent to the wn counter 6, the vertical up/down counter 6 outputs 2, and the read addresses are 28, 27, 26, 25, 24.2B.

It changes to 22.21.

Similarly, when all read addresses are input to the frame memory 2, the frame memory 2 outputs image data corresponding to read addresses 11 to 88, and the image data is printed out by the print mechanism and horizontally reversed. An image is obtained.

Also, when obtaining a 90° rotated image, multiplexer 3
and 4, the horizontal address and vertical address are exchanged and input to the frame memory 2, and the data rotated by 90 degrees is output.

Furthermore, when obtaining a reduced image, the frequency divider 7 changes the period of the read clock to reduce the read address (see FIG. 20).

As described above, the printer device 1 can move up/down in the horizontal direction.
A royal image, an inverted image, and a horizontally inverted image are obtained by changing the up/down direction of the counts of the d o w n counter 5 and the vertical up/down counter 6, and the readout clock is changed by the frequency divider 7 and read out. Since it is configured to reduce the address, the horizontal up/down counter 5 and the vertical up/down counter 5
There is a problem in that the control with the do w n counter 6 becomes complicated, which tends to increase the circuit scale of the device.

It is something to do.

[Operation] Based on the above configuration, the printer device of the present invention has the following features:
Data on the video screen is stored in a frame memory, and a clock for reading data stored in the frame memory is input to a vertical address counter.The vertical address counter, which receives the clock, outputs a vertical address. When the count-up signal of the address counter is input, the horizontal address counter counts the horizontal addresses, and depending on the selection means, the frame image is erect image, inverted image, 2-split image, horizontally reversed image, 90m rotated image, reduced image, enlarged image. horizontal direction in the storage means that stores control information for printing modes such as erect image of frame image, inverted 2-split image, horizontally reversed image, 90° rotated image, reduced image, enlarged image, etc. When the output addresses of the address counter and the vertical address counter are input, the address converted based on the mode selected by the selection means is output from the storage means.

[Example 1] An example of the present invention will be described below with reference to the drawings. Note that the same parts as in FIG. 15 are denoted by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 1, the printer device 1 has a ROM 12 as a storage means connected to the A input of the multiplexer 3 and the B input of the multiplexer 4.
2 is configured to output an address converted into a predetermined designated mode with respect to an input address.

In addition, the A input of multiplexer 4 and the multiplexer 3
The ROM 13 has a ROM 13 as a storage means connected to the B input of the ROM 13, and the ROM 13 is configured to output an address converted into a predetermined specified mode with respect to the input address, and these ROMs 12 and 13 are , has a storage capacity of 32 Kbytes in the embodiment.

Further, the ROM 12 is connected to a vertical address counter 14 that manually counts a read clock for reading data stored in the frame memory 2 and outputs a vertical address, and a keyboard 15 as a selection means. The keyboard 15 is provided with a composition instruction key 15a for instructing composition and a rotation key 15b for instructing rotation.

The ROM 13 contains a vertical address counter 1.

Note that the frame memory 2 has first and second fields, and the addresses in the vertical direction are interlaced (interleaved allocation) to the first and second fields (see FIG. 2).

Next, the operation of this embodiment will be explained.

Frame printing mode As is well known, the video signal in the standard television system is
One frame is made up of an odd field and an even field, and the frame memory 2 has different areas for each of these fields. For this reason, a video printer prints a single image by reading data alternately from both fields. frames can be sequentially printed out, and in the frame printing mode, such data is read out alternately from both fields.

When obtaining a frame stamp image (erect image), the operator instructs frame printing mode using the composition instruction key 15a of the keyboard 15.

Then, ROM1 receives the signal from the composition instruction key 15a.
2 and ROM 13 are set to frame printing mode (see FIG. 3).

The read clock is then input to the vertical address counter 14, which outputs the read address as a count value.

At this time, the horizontal address counter 16 outputs 1 as the initial read address until a count-up signal is received from the vertical address counter 14.

And the read address is ROMI 2 and ROM
1B, is converted by these ROM12 and ROM13 as shown in FIG. 3, and is output.

Then, the output addresses output from the ROM 12 and ROM 1B are input to the eight multiplexers 3 and 4, and output to the frame memory 2 from the Y output.

Further, the frame memory 2 outputs data corresponding to the output address.

For example, when the vertical address counter 14 sequentially outputs read vertical addresses starting from 1, the horizontal address counter 16 outputs 1 as the initial read vertical address, and the read addresses are shown in FIGS.
As shown in the figure, 11.21, 31, 41.51, 61
, 71°81.

When the vertical address counter 14 counts 8, a count up signal is sent from the vertical address counter 14 to the horizontal address counter 16, the horizontal address counter 16 outputs 2, and the read address is 12°22. .32, 42, 52, 62.72
．． It changes to 82.

In this way, the read address is set to frame memory 2.
, the frame memory 2 outputs image data corresponding to read addresses 11 to 88, and the image data is printed out by a printing mechanism to obtain a frame stamp image (erect image) royal image.

Field printing mode When performing video printing, it is possible to print an image using only one of the field data, and in this case, the data in frame memory 2 is limited to the contents of one of the selected fields. is used. At this time, data loss is prevented by reading the data of the selected field twice in duplicate instead of the other field which is originally interlaced scanned.

That is, when obtaining a field stamp image, the operator instructs the field printing mode using the composition instruction key 15a of the keyboard 15.

Then, ROM1 receives the signal from the composition instruction key 15a.
2 and ROM 1B are set to field printing mode (see FIG. 5(a)).

For example, when printing the first field, the read clock is input to the vertical address counter 14, and the vertical address counter 14 outputs the read address as its count value.

At this time, the horizontal address counter 16 outputs 1 as the initial read address until a count-up signal is received from the vertical address counter 14.

The read address is ROM12 and ROM1.
3, is converted by these ROM 12 and ROM 13 as shown in FIG. 5(a), and is output.

Then, the output addresses outputted from ROMI 2 and ROM 13 are inputted to the multiplexers 3 and 4, and outputted to the frame memory 2 from the Y output.

As a result, data corresponding to the output address is output from the frame memory 2, and printing is performed only from the desired field data.

For example, when the vertical address counter 14 sequentially outputs read vertical addresses starting from 1, the horizontal address counter 16 outputs 1 as the initial read vertical address, and the vertical address and horizontal address are Figure 5(a) by ROM1B
The read address is 11, 11, 3.

Then, the output addresses outputted from ROMI2 and ROM1B are inputted to the multiplexers 3 and 4, and outputted to the frame memory 2 from the Y output.

Further, the frame memory 2 outputs data corresponding to the output address.

For example, when the vertical address counter 14 sequentially outputs read vertical addresses starting from 1, the horizontal address counter 16 outputs 1 as the initial read vertical address, and the vertical address and horizontal address are stored in the ROM 12 and ROM 13. It is converted as shown in Figure 6, and the read addresses are 11.31, 51, 71,

It changes to 33.53°73 (see Figure 7).

Therefore, with such overlapping two-time readout, one of the field data is repeated twice in the readout direction to print two identical images. and,
When one field is completed, approximately similar data is read out from the other field, and this is also read out twice, so the multi-field data is printed as two identical images, and as a result, the first It is possible to print a total of four divided teeth, two from the first field and two from the second field.

In this way, the read address is set to frame memory 2.
When input to the frame memory 2, the frame memory 2 outputs image data corresponding to read addresses 11 to 78, and the image data is printed out by a printing mechanism to obtain a four-part image.

Note that if the first field and the second field are subjected to inversion/rotation, which will be described later, different image data will be displayed as 4 as shown in Figure 8.
