Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color figure creation processing method, and more particularly to a method for electrically processing and coloring an input figure to edit and create a desired color figure.

Conventionally, when creating color figures, the method used was to draw line drawings on paper or the like with black ink, and then color them with paints such as anime colors. Therefore, the coloring process took a considerable amount of time and required excellent technique. Furthermore, it is difficult to obtain paints of exactly the same color at all times, and if color figures are encoded using a small number of bits, graphic input devices such as commercial TVs
The problem is that the amount of code increases due to camera shading, noise, etc., and the reproduced image becomes untidy. Furthermore, if you wanted to modify the color of a part of a color figure that you had already created, you had to redraw the color figure from the beginning.

In order to eliminate these drawbacks, the present invention automatically detects the region of the input shape so that the coloring and color correction of the input shape can be performed automatically automatically, and when the operator specifies the desired color for the region, the color is changed to that color. The drawings will be explained in detail below.

Note that the region here refers to a set of adjacent pixels having the same color information.

FIG. 1 shows the configuration of an embodiment of the present invention, in which 1 is a graphic input section, 2 is an encoding section, 3 is a buffer memory,
4 is a decoding section, 5 is a mixing section, 6 is a display section, 7 is an area detecting section, 8 is an area display signal generating section, 9 is a color specifying section, 10 is a coloring section, and 11 is a control section.

To operate this, first an input figure is set in the figure input section 1, and this is converted into an electrical signal.
As the graphic input section 1, for example, a flying spot scanner commercial TV camera is used. Encoding section 2
is a part that converts the output signal of the figure input unit 1 into a digital signal and encodes it, and encodes the black part of the figure by making it correspond to "1" and the white part to "0", for example.
Then, the code is stored in the buffer memory 3.
The decoding section 4 reads and decodes the codes stored in the buffer memory 3, and the output signal thereof is mixed with the output signal from the area display signal generation section 8 in the mixing section 5 and displayed on the display section 6. is being done. The area detecting section 7 detects only one area of the input figure, and specifically checks the code stored in the buffer memory 3 and detects the area. The area display signal generator 8 generates a display signal for indicating the area detected by the area detector 7, and is mixed with the output signal from the decoder 4 in the mixer 5. The color specifying section 9 specifies the color to be colored in the area displayed on the display section 6, and uses a pushphone, for example. The coloring unit 10 is the area detection unit 7
The color specification section 9
In response to a designation from , the code of the buffer memory 3 is forcibly converted so that the area becomes the designated color. The control unit 11 controls each unit to sequentially execute the above-described operations on all areas of the input figure.

The flow of the operation of the present invention has been described above, but further explanation will be added regarding the area detection section 7 and the area display signal generation section 8.

FIG. 2 shows the configuration of an embodiment for explaining the area detection section 7 in more detail, in which 701 is a code reading section, 702 is a determination section, and 703 is an area determination section. The code reading unit 701 sequentially reads the contents of the buffer memory 3. The determination unit 702 determines whether the readout code has not been colored yet, and the area determination unit 703 determines the area that includes the uncolored points detected by the determination unit 702. . The area determination unit 703 determines the area by, for example, sequentially tracing the boundary line and sequentially detecting inner points.

FIG. 3 shows the configuration of an embodiment for explaining the area display signal generating section 8 in more detail, in which 801 is an area reading section and 802 is a display control section. The area reading unit 801 reads the area detected by the area detection unit 7, and the display control unit 802 counts vertical synchronization signals for display and turns on/off the display so that the operator can clearly recognize the detected area. This is to perform off control and display blinking on the display unit.

In the case of the present invention, the following method can be adopted as necessary for color correction and region detection order determination.

If the code determination method of the determination unit 702 is configured to detect only codes that have not been colored and have a specific color, the color of the input figure can be easily corrected.

If the region detecting section 7 and the coloring section 10 forcefully change all codes of a specific color in the buffer memory 3 to codes of other colors, a color correction different from that described above can be realized.

In the area detection unit 7, the order in which areas are detected is usually fixed, such as starting from the upper left corner of the input figure, but if an input device that specifies the starting position, such as a light pen, is used, areas can be detected from any position. Can be done.

As explained above, since the area of the input figure is automatically detected and the area is displayed on the display, the operator only has to specify the color, which reduces the time it takes to create color figures. It has the advantages of eliminating the need for paint, and enabling efficient graphical encoding.
