Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for creating and processing relatively simple color figures such as illustration figures, and more particularly to an apparatus for applying a desired color to each area of a figure.

For example, if you want to color each part of a figure for which only the outline is given, you can display the various colored states as a color image, look at the image, and selectively change the color of each part. , and displaying it may be repeated to obtain a desired color image.

Alternatively, the same thing can be considered when changing the color of a part of a color image. In order to create a color figure in this way, in the past, each pixel of the figure was encoded using PCM, the resulting code was stored in a buffer memo, and at least one point in the area to be colored was combined with the color to be colored. When an operator specifies , the code is replaced each time so that the color of the code in the specified area becomes the specified color.

That is, for example, as shown in FIG. 1, the input figure has three areas d.
, ~d3, and each pixel of the figure has red (R), green (G), and blue (B) as shown in Figure 2.
The degree of color is stored as a code (R, G, B,) for area d, and color information is similarly shown for each area and public. Color information is stored in buffer memory. The color of that area is also changed from code (R303B3) to (R3'
GJ&′), area d3 in the buffer memory
The codes corresponding to were replaced as shown in FIG. Therefore, waiting time is required for code replacement each time the coloring is changed, and since it is performed for each pixel, there is a large amount of processing involved, so a method in which a single control unit controls the buffer memory that can be used for a large number of terminals has been developed. had the disadvantage of being unsuitable. Furthermore, when changing the color designation of a set of terminals repeatedly, it took a long time to process. SUMMARY OF THE INVENTION An object of the present invention is to provide a color graphic creation processing device that has a high processing speed, has a short waiting time when changing colors repeatedly, and can be shared by many terminals.

According to this invention, the code is extracted from the buffer memory at the step of detecting a code in the area to be colored and replacing the detected code with a special code to obtain a display signal, that is, when obtaining a color image signal. When the special code is displayed, this code is switched to the color code designated by the operator and output.

By supplying the display signal obtained in this way to a display device, a color image can be obtained, and it is possible to obtain an image of the designated color without changing the layers in the buffer memory every time the color is converted. In this manner, when the operator specifies various colors and obtains the desired color, the special code in the buffer memory is replaced as necessary with a code that displays the color specified by the operator. The input graphic is encoded, for example, as shown in FIG.

That is, after the code (RiGiBi) indicating the color, there is a code RLii indicating the number of consecutive pixels that change color, the so-called run length.
This is an example of run-length encoding using Assuming that area d3 is the area to be colored, first a code within the area d3 is detected, and the detected code is replaced in the buffer memory with a special code (RoGoBo) as shown in FIG. Next, when extracting a code from the buffer memory at the stage of obtaining a display signal, it is checked whether the extracted code is a special code or not, and if it is not a special code, the color specified by the code is used as is in the display signal. In the case of a special code, color conversion is performed so that the display signal becomes the color specified by the operator (R3'G3'B3') as shown in FIG. That is, when the special code in the buffer memory is decoded, the display color is set to the color specified by the operator. Therefore, when the operator changes the color specified one after another, the special code in the buffer memory is not replaced at all, and the display color in that area changes in real time, and there is no need to wait for coloring. do not have. When the operator obtains the desired color, the special code in the buffer memory is replaced with a code that will display the color specified by the operator, as shown in FIG.

Therefore, the steps of accessing the buffer memory and replacing the stored codes for one area are {1) replacing the code in the area to be colored with a special code; There are only two steps, the step of replacing the code with the color display code assigned to the code, and the operator only has to wait for the code replacement process twice for one area. Conventionally, each time the color specification for one area is changed, code replacement processing is waited for, so the color specification is changed to three times for one area.
If the process is performed more than once, the present invention can process the process at a higher speed. FIG. 6 shows an example of a color figure creation processing device according to the present invention, in which a figure input section 11 inputs a figure that is the basis of a color figure to be created, such as a black and white binary figure or a color figure that requires correction. It encodes and outputs the code, and the code is stored in the buffer memory 12.

The discussion unit 13 discusses the code from the buffer memory 2,
There is no code conversion unit 14, and the proposed code is given to the code processing unit 15. The color specifying section 16 holds the colors to be applied to the area of the figure, for example, R, G, and B.
R, G, and B are initialized at 8 and 19, and R is set from terminal 21.
The value of R is increased by the input of 10, and the value of R is decreased by the input of R-.
, G-, B-, B- from the terminal 23 operate in the same manner, and any desired color can be specified from the outside to the color specifying section 16. The code converting section 14 replaces the color of the special code among the continuously repeatedly read codes with the color of the color specifying section 16 and outputs the special code.

The signal output section 24 includes the code conversion section 14 and the clock generation section 28.
The outputs of these are combined to generate a signal necessary for the monitor 26, for example, N
Output as TSC signal. The color of the area that has become a special code in this way is displayed on the monitor 26 in the color specifying section 1.
6 can be changed arbitrarily by operating it from the outside. The instruction section 25 specifies the area to be colored.

The code processing unit 15 detects a code within the designated area from within the buffer memory 2, and controls the output unit 13 and the writing unit 27 to replace the detected code with a special code. After the operator colors the area several times, when it is confirmed by the reproduced image on the monitor 26 that the desired color has been obtained, the code replacement display S is performed at that point. Then, the code processing unit 15 replaces the special code in the buffer memory 12 with a code representing the color specified by the color specifying unit 16. For example, the configuration of the code processing unit 15 that detects the code within the specified area is Hakama Fumoaki 52, which has already been filed by the present applicant.
-118888 can be used. The clock generator 28 supplies clocks such as synchronization signals. Although one embodiment of the present invention has been described above, the code processing unit 15
Among the codes stored in the buffer memory 12,
The present invention is also applicable to automatically detecting uncolored areas.

In this case, as shown in FIG. 7, a determination bit C for identifying whether the code is a colored code or an uncolored code may be added as a code format, and the determination bit may also be controlled. In this case, in order for the detected colored area to be easily recognized by the operator, the special code is not simply converted into the color of the color specification section 16 by the code conversion section 14, but is obtained by the clock generation section 28. It is sufficient to count the synchronization signals and insert a color obtained by inverting the color bits of the color specifying section 16 once every 30 frames, for example. As explained above, according to the apparatus of the present invention, a specific area of a figure can be colored in any color specified by the operator any number of times in real time without changing the code stored in the buffer memory. Therefore, there is an advantage that there is no need for waiting time every time coloring is performed as in the conventional method. In addition, because it uses a run-length encoding method that allows color display, unlike conventional PCM, the amount of code is not large, and as a result, code replacement in the buffer memory can be performed in a short time, and many It has the advantage that it is easy to multiplex buffer memories compatible with multiple terminals.
