The output data are inputted in a selection circuit 5 where the data are selected so that the selected ones can be written on the bit plane of a designated frame memroy 4. The selected data are written on each corresponding bit plane of the frame memory 4 through a display controller 7. At the same time, each data of red (R), green (G), and blue (B) corresponding to the picture element data of the frame memory 4 are read out from a preset color lookup table 6 and the read out data are inputted in a color CRT9 after they are digital-to-analog converted at a video processor 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a color and pattern composition device that not only corrects and adds a pattern but also creates a pattern, and in particular, combines a plurality of patterns to create a new pattern.

Structure of conventional examples and their problems In recent years, in the fields of printed fibers, textiles, etc., designs drawn by designers are automatically read, corrected, and edited using color design reading devices, microcomputers, color design display devices, etc. Systems are being developed to do this. The basic functions of such a system are generally to read color patterns and to make corrections and additions using a tablet device for inputting coordinates on the pattern display device.

Now, in the creation of such conventional designs, generally the main things were movement, development, nine rotations, four reversals, etc.

There are some models that have a compositing function, but basically, the newly sent compositing pattern data is transferred to the compositing pattern displayed on the color pattern display device. In many cases, each pixel is processed and synthesized using software stored in firmware (fixed program storage) on a microcomputer built into the device. Now, when compositing a pattern like this by handling one pixel data at a time,
In place of the displayed pattern data, if you want to not only rewrite the composite pattern data but also perform compositing of multiple target color data specified in the composite pattern, it will be very difficult for the software to determine the composite target color. There was a problem that it took a long time.

Purpose of the Invention In view of the above-mentioned drawbacks of the conventional art, the present invention provides a method for quickly converting only a plurality of designated target colors among the compositing patterns transferred from a host computer etc. to the displayed compositing pattern. At the same time as combining multiple black and white binary images,
The present invention also provides a color pattern synthesis device that can distinguish overlapping areas as separate data and obtain an arbitrary color scheme image.

Composition of the Invention The color pattern display device according to the present invention has a frame memory consisting of a plurality of bit planes that stores patterns to be synthesized and can be read and written at will. It consists of an extraction circuit that extracts specified target color data from a frame memory, and a selection circuit that selects a bit plane of the frame memory.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a color pattern synthesis device showing an embodiment of the present invention.

First, a command code sent from a host computer or the like and a series of commands consisting of a plurality of parameters are decoded by a microcomputer 2 via an interface 1. Then, the target color is set/read to the target color extraction circuit 3 composed of a random access memory, the mask plane is set to the selection circuit 5 that selects the writing bit plane of the frame memory 4, and furthermore, the target color is read to the target color extraction circuit 3 composed of a random access memory. Parameter settings are made.

On the other hand, pattern data to be synthesized sent from a host computer or the like is inputted to a target color extraction circuit 3 via an interface 1 and a switching circuit IA that switches writing/reading of pattern data. This target color extraction circuit 3 is composed of a random access memory, and sets the contents of the specified target color data as an address to the same value as the value of that address, and sets all contents at addresses other than the target color to 0. It is preset so that Then, when the contents of the design data to be synthesized inputted to the target color extraction circuit 3 are read out from the random access memory in the target color extraction circuit 3 as address data, the data is outputted as ○ except for the specified color. Ru. Of course, if the designated colors are all colors, the contents of the random access memory will all be the same value as each address value, that is, a linear function. It is also possible to perform a color data change process in which a specific color is replaced with another color to make the same color.

Now, the output data from the target color extraction circuit 3 is input to the selection circuit 5, and selected so as to be written into a designated bit plane of the frame memory 4. The selected data is written to each corresponding bit plane of the frame memory 4 via the display controller 7.

At the same time, the preset color lookup table 6 also corresponds to the pixel data in the frame memory 4).

Green (q) and blue (B) data are read out, digital-to-analog converted by the video processor 8, and input to the color CRT 9, where the composite pattern is displayed.

Next, the pattern data for compositing sent from the host computer etc. is basically written into the frame memory 4 through the same route as the pattern to be synthesized.

However, the target color of the composite pattern also needs to be set in advance before transferring the composite pattern data, and the selection circuit 5 also needs to select the bit plane of the frame memory 4 in advance. The bit planes selected by the selection circuit 5 are determined so that they do not overlap each other in the case of a pattern to be combined and the case of a combined pattern. In this way, the writing of the pattern data to be combined into the frame memory 4 and the writing of the combined pattern into the frame memory 4 are performed by dividing the bit plane into two and using the respective bit planes.

On the other hand, 1o is a frame memory for graphics,
In the video processor 8, the image is simultaneously displayed so as to overlay the symbol display in the frame memory 4. moreover,
Coordinate values corresponding to the display screen are input from the coordinate input tablet device 11, and are input to a host computer etc. via the interface 1 via the address converter 12 and the microprocessor 13. is sent to the computer 2 and sent to the cursor generator 14 via the display controller 7.
is input. The cursor generator 14 generates a cursor at the designated coordinate value, and displays the cursor so as to simultaneously overlay it with each memory data of the pattern and graphics.

As a result, while viewing the screen being displayed, the user can also use the coordinate input tablet device 16 to indicate the position of the symbol using the cursor. Note that 15 is a read-only memory (ROM), and the microcomputer 2
The symbol processing software executed by is stored. Specifically, processing software such as movement, expansion, two rotations, two inversions, and filling will be explained about the combination of three types of binary patterns in the composition method.

Figure 2a shows an example in which three types of binary patterns A, B, and C are synthesized, and the number of colors in the composite pattern after synthesis is 2 to the third power, that is, 8. becomes. That is,
Binary pattern A is assigned to the plane of, for example, the least significant bit o out of 8 bits of frame memory 4, binary pattern B is assigned to bit plane 1, and binary pattern C is assigned to bit plane 2. Note that bit planes do not necessarily have to be allocated in order, but they should be made so that they do not overlap for each symbol.
If the symbol is not yet a binary symbol, for example, if the symbol includes a symbol having color numbers ◯ to 4, it is necessary to use bit planes of the same symbol continuously.

FIG. 3a shows an example in such a case. As shown in Figure 3, the color numbers after composition are 10 colors from 0 to 9, but the target color number in pattern B for pattern A is 0.1.
．． Since the four colors 3.4 are the targets of composition, color numbers 6 and 7 do not actually exist in the color numbers after composition.

Next, the configuration of the selection circuit 5 will be explained in more detail with reference to FIG.

FIG. 4 is a block diagram showing the main parts of the bit plane selection circuit 5. As shown in FIG.

Bit plane write mask data 41 from the microcomputer 2 is set in advance in a mask register 43 by a signal from a setting line 42.

Next, each time the symbol data 44 is transferred pixel by pixel, it is set in the parallel input/parallel output shift register 45, and shifted upward by the specified number of bits according to the shift signal 46. This output data is given as input data to each bit plane via a buffer 47. On the other hand, the write signal 48' to the bit plane is gated via the logic element groups 49 and 50 by the output of the mask register 43 mentioned above, and is used as a write selection signal for each bit plane. In this way, the data of the composite pattern is gated and output to a desired bit plane, thereby performing the composite.

Next, the color lookup table will be explained. FIG. 5 shows the lookup table of the color lookup table 6. As shown in FIG. The output data from the frame memory 4 is simultaneously read out and given as address data to a random access memory (RAM) that can be read and written arbitrarily. / Analog conversion to color CRT
9 to display the color corresponding to the color number on the color CRT 9.

Effects of the Invention The present invention significantly reduces the enormous amount of time required to synthesize multiple designs using firmware-based software as in the past, and also enables the synthesis of multiple binary designs. This makes it possible to generate matching areas as different color numbers, and by combining a plurality of simple designs, it is possible to easily create new designs, which is highly effective.
