The intention of or will be explained later.

(3) Operation Next, the operation of the first embodiment having the above configuration will be described with reference to FIGS.
This will be described with reference to FIG. Here, a description will be given of a process of spray painting the periphery of the character image (basic image) as shown in FIG. 6B with respect to the character image (basic image) shown in FIG.

First, when the apparatus power is turned on, the CPU 2
Reads out and loads a predetermined image drawing program from the ROM 3, and executes the step SA1 of the spray paint process shown in FIG. In step SA1, various registers / flags in the RAM 4 are initialized, while instructing the VDP 5 to initialize the VRAM 6 and internal registers.

When the initialization in step SA1 is completed, the CPU 2 advances the processing to step SA2, reads the basic image data from the storage area BI of the ROM 3, and writes it in the image area A of the RAM 4. Subsequently, in step SA3, the storage area IM
The cursor coordinate initial values (x ₀ , y ₀ ) are read from X and IMY, and stored in the registers MX and MY of the RAM 4. Next, at step SA4, the CPU 2 stores the cursor image stored in the storage area CI of the ROM 3 on the basis of the cursor coordinate initial values (x ₀ , y ₀ ) stored in the registers MX and MY in the image area B of the RAM 4. Write to.

When the basic image and the cursor image are stored in the image areas A and B of the RAM 4, respectively,
U2 releases the interrupt mask, and DMA-transfers the contents of the image areas A and B to the VRAM 6 in synchronization with the vertical blanking period of the display device 8. That is, when the interrupt mask is released, the CPU 2 executes the interrupt processing shown in FIG. 5 for each vertical blanking period of the display device 8, and writes the basic image and the cursor image respectively written in the image areas A and B of the RAM 4. Are DMA-transferred to the VRAM 6 via the VDP 5 (step SB1). V
The image data transferred to the RAM 6 is displayed on the screen of the display device 8 by the VDP 5. Thereby, for example, the basic image shown in FIG. 6A is displayed on the screen.
In FIG. 6A, the screen display of the cursor image is omitted.

Returning to FIG. 3, the spray paint process will be described. When the mouse 1 is moved and operated while the basic image is displayed on the screen as described above, the result of the determination in step SA5 becomes "YES", and the process proceeds to step SA6. Step SA6
Then, the contents of the registers MX and MY are updated according to the coordinate values (x, y) displaced in accordance with the moving operation, and thereafter, the process returns to step SA4. As a result, the position of the mouse cursor displayed on the screen moves according to the updated contents of the registers MX and MY.

If the mouse 1 has not been moved, the result of the determination at step SA5 is "NO",
CPU 2 proceeds to step SA7. Step S
In A7, it is determined whether or not the mouse 1 has been turned on. Here, if the ON operation is not performed, the determination result is “NO”, and the process returns to the above-described step SA4. However, if the mouse 1 is turned on to perform spray painting, the determination result is “YES”, and the step SA8
Processing proceeds to

In step SA8, the CPU 2 reads the color data (color code) of the dot in the image area A corresponding to the cursor coordinate value (x, y) stored in the registers MX and MY, and sets this in the register RefColor. . That is, the color data (color code) of the portion to be spray-painted on the display screen is stored in the register RefC.
That is, it is stored in color. Thereafter, the CPU 2 returns to FIG.
The process proceeds to step SA9 shown in (1) to determine whether or not a cursor movement instruction has been issued, that is, whether or not the mouse 1 has been moved to trace a portion to be spray-painted.
When tracing on the screen to spray paint,
The mouse 1 is maintained in an on state by performing a so-called drag operation.

In step SA9, when a drag operation is performed to perform spray painting, the determination result is "YES", and the process proceeds to the next step SA10. However, when a drag operation is not performed, the determination result is "YES". "NO", and the process proceeds to Step SA16 described later. At Step SA10, the values of the registers MX and MY are updated in accordance with the drag operation, and the subsequent Step SA
At 11, the display position of the cursor image is moved based on the updated cursor coordinate values (x, y) of the registers MX and MY.

Next, when the flow advances to step SA12, CP
U2 reads out the color data (color code) of the dot on the image area A corresponding to the cursor coordinate value (x, y) stored in the registers MX and MY, and stores it in the register Now.
Set to Color. In step SA13, it is determined whether or not the color data (color code) set in the register NowColor matches the color data (color code) set in the register RefColor.

That is, it is determined whether or not the color (designated color) of the part which is initially determined to be spray-painted matches the color (current color) of the part to be spray-painted now. When the designated color does not match the current color, it is considered that the part other than the designated color is spray-painted, and the determination result is "NO", and the process proceeds to step SA16 without performing the painting process.

On the other hand, if the designated color matches the current color, the result of the determination in step SA14 is "YE
S ", and the process proceeds to Step SA14. In step SA14, first, a dot area within a predetermined range around the dot designated by the cursor is set. For example,
When setting a circular dot area, a group of dots that fall within a radius r around the dot (x, y) designated by the cursor is specified.

In the next step SA15, only the color data (color code) that matches the register RefColor in the set dot area is drawn in a spray shape by changing the color to a specific color. This allows, for example,
In the basic image shown in FIG. 6A, the mouse 1 is turned on in the background portion, the color of the background portion is set to “designated color”, and the mouse 1 is dragged along the periphery of the character image. Then, a spray paint is applied in which the tracing edge is changed to a spray-like specific color by a drag operation. In this case, since only the dots that match the designated color are changed to the specific color, there is no risk of being sprayed on the character image.

When the spray painting is performed, the CPU 2 proceeds to step SA16 to determine whether the mouse 1 has been turned off, that is, whether the drag operation has been completed. Here, when the drag operation has not been completed, the determination result is “NO”, and step S
The process returns to A9, and the above-described process is repeated again. On the other hand, when the drag operation is completed, the determination result is “YE
S ", and the process returns to step SA4 (see FIG. 3) described above.

As described above, according to the first embodiment, the mouse 1 is used in the image portion to be spray-painted.
Set the color of the part to "specified color" by turning on, and drag while dragging the part you want to paint, only the dots that match the specified color in the traced part will become the spray-like specific color Since the color is changed, the operation of designating a mask as in the related art becomes unnecessary, and it is possible to prevent overwriting of a portion other than a desired portion by only a simple designation operation.

B. Second Embodiment Next, a second embodiment will be described with reference to FIGS. Note that the second embodiment has the same configuration as the above-described first embodiment, and a description thereof will be omitted. Hereinafter, a memory configuration and an operation different from those of the first embodiment will be described.

(1) Memory Configuration The memory configuration of the ROM 3 and the RAM 4 in the second embodiment will be described with reference to FIG. In FIG. 7, the same reference numerals are given to the storage areas and registers common to the first embodiment, and the description thereof will be omitted.

First, FIG. 7A is a memory map showing the memory configuration of the ROM 3. The difference from the first embodiment shown in FIG. 2A is that a color data search table CST is provided. That is. In the above-described first embodiment, “specified color” is set, but this can be applied only to a single color area. Therefore, in the second embodiment, the color data search table C is set so that it can be applied to an area where a plurality of colors similar to the designated color are mixed.
ST is provided. This color data search table CST
Is assigned a plurality of similar colors similar to the “designated color” in advance, and reads out the corresponding plurality of similar colors using the color data (color code) of the dot designated by the cursor, that is, the “designated color” as a read address. It is a data table.

Next, FIG. 7 (b) is a memory map showing the memory configuration of the RAM 4. The difference from the first embodiment shown in FIG. 2 (b) is that Registers RefColor (1) to (n) for temporarily storing color data (color code) and color data of a plurality of similar colors read from the color data search table CST in response thereto are provided. Therefore, register RefCol
or (1) stores color data of the dot designated by the cursor, and registers RefColor (2) to (n) store color data of a plurality of similar colors corresponding to the color data (color code) of the dot designated by the cursor. Stored.

(2) Operation Next, the operation according to the second embodiment will be described with reference to FIGS. As in the first embodiment, when the apparatus is first turned on, the CPU 2 reads out and loads a predetermined image drawing program from the ROM 3, and executes step SC1 of the spray paint process shown in FIG. In step SC1, various registers / flags in the RAM 4 are initialized, while instructing the VDP 5 to initialize the VRAM 6 and internal registers.

When the initialization is completed, C
The PU 2 advances the process to step SC 2, reads the basic image data from the storage area BI of the ROM 3, and writes it to the image area A of the RAM 4. Subsequently, in step SC3, the cursor coordinate initial values (x ₀ , y ₀ ) are read from the storage areas IMX, IMY of the ROM 3 and stored in the registers MX, MY of the RAM 4. Then, step S
When the process proceeds to C4, the CPU 2 reads the ROM based on the cursor coordinate initial values (x ₀ , y ₀ ) stored in the registers MX and MY.
The cursor image stored in the storage area CI of No. 3 is R
Write to image area B of AM4.

When the basic image and the cursor image are stored in the image areas A and B of the RAM 4, respectively, the CPU 2 releases the interrupt mask, and synchronizes the image areas A and B with the vertical blanking period of the display device 8. VRA content
DMA transfer to M6 (see interrupt processing in FIG. 5). When the mouse 1 is moved while the basic image and the cursor image are displayed on the screen in this manner, the result of the determination in step SC5 becomes “YES”, and the process proceeds to step SC6. In step SC6, the register M is set according to the coordinate value (x, y) displaced according to the moving operation.
The contents of X and MY are updated, and thereafter, the above-mentioned step SA4
Return to processing. As a result, the updated registers MX,
The position of the mouse cursor displayed on the screen moves according to the content of MY.

On the other hand, if the mouse 1 has not been moved, the result of the determination in step SC5 is "NO", and
CPU 2 proceeds to step SC7. Step S
At C7, it is determined whether or not the mouse 1 has been turned on. Here, if the ON operation is not performed, the determination result is “NO”, and the process returns to step SC4. However, if the mouse 1 is turned on to perform spray painting, the determination result is “YES”. The process proceeds to Step SC8 shown in FIG.

At step SC8, the CPU 2 sets the cursor coordinate values (x, y) stored in the registers MX and MY.
Is read out and the color data (color code) of the dot in the image area A is read out and set in a temporary register (not shown). Subsequently, in step SC9,
Using the color data set in the temporary register, that is, the “designated color” as a read address, the corresponding color data of a plurality of similar colors is read from the color data search table CST. In step SC10, the color data of the dot designated by the cursor is stored in the register RefC.
The color data stored in the color data search table CST is stored in the registers RefColor (2) to (n), respectively.

Next, when the flow advances to step SC11, the CP
U2 determines whether or not there is a cursor movement instruction, that is, whether or not the mouse 1 has been moved to trace a portion to be spray-painted. When the user traces the screen for spray painting, the mouse 1 is kept on by performing a so-called drag operation. By the way, step SC11
When the drag operation is performed to perform spray painting, the determination result here is “YES”, and the process proceeds to the next step SC12. However, when the drag operation is not performed, the determination result is “NO”, and a step described later is performed. The process proceeds to SC18 (see FIG. 10).

In step SC12, the values of the registers MX and MY are updated in accordance with the drag operation, and
At C13, the display position of the cursor image is moved based on the updated cursor coordinate values (x, y) of the registers MX and MY. Next, when the process proceeds to step SC14 in FIG. 10, the CPU 2 reads out the color data (color code) of the dot on the image area A corresponding to the cursor coordinate value (x, y) stored in the registers MX and MY and reads this. Set in register NowColor.

In step SC15, the color data (color code) set in the register NowColor is set to one of the "designated color" and the "similar color" stored in the registers RefColor (1) to (n), respectively. It is determined whether they match. That is, it is determined whether or not the color of the portion that is initially determined to be spray-painted (designated color) and any of its similar colors match the color of the portion where spray-painting is to be performed (current color). If none of them match, it is considered that the parts other than the designated color and the similar color are spray-painted, and the determination result is "NO", and the process proceeds to step SC18 without performing the paint processing.

On the other hand, if the current color matches one of the designated color and any of its similar colors, step SC1
The determination result of 5 is “YES”, and the process proceeds to step SC16. In step SC16, first, a dot area within a predetermined range around the dot designated by the cursor is set. For example, when setting a circular dot area, a group of dots that fall within a radius r around the dot (x, y) designated by the cursor is specified.

Subsequently, in step SC17, the register RefColor (1) is set in the set dot area.
Only the color data (color code) that matches any one of (a) to (n) is drawn in a spray shape by changing the color to a specific color. As a result, in the image portion traced by the drag operation, only the dots that match the designated color and its similar color are changed to the specific color, so that an image that does not include the designated color and its similar color is not designated as a mask. Both can prevent spray paint.

When the spray painting is performed, the CPU 2 advances the process to step SC18 to determine whether the mouse 1 has been turned off, that is, whether the drag operation has been completed. Here, when the drag operation is not completed, the determination result is “NO”, the process returns to step SC11 in FIG. 9, and the above-described process is repeated again. On the other hand, when the drag operation is completed, the determination result is “YES”, and the process returns to step SC4 (see FIG. 8) described above.

As described above, according to the second embodiment, the mouse 1 is turned on at the image portion to be spray-painted to set the color of the portion to the “specified color”, while the “specified color” is set. Are extracted with reference to the color data search table CST, and a portion to be painted is traced while being dragged, so that the traced portion matches the designated color and any of its similar colors. Only the dots are changed to a spray-like specific color. Therefore, as in the first embodiment, overwriting of a portion other than a desired portion can be prevented by a simple designation operation as compared with a conventional device requiring a mask designation, and in a portion where a plurality of colors are mixed. It is also possible to apply.

In the above-described first and second embodiments, the case of spray painting has been described as an example. However, the present invention is not limited to this case. It is possible. In the first and second embodiments, the spray paint is performed in a fixed specific color. However, the spray paint may be performed in a manner in which a color is specified according to a user's specification.

[0055]

According to the present invention, when a position to be drawn in an image displayed on a screen is designated, the color at that position is designated as a drawing target color. It is determined whether or not the color at the drawn position matches the drawing target color, and only when the color matches, the color at the drawing position is drawn in a specific color. Therefore, since a specific color is not drawn in an area other than the drawing target color in the image, overwriting other than a desired portion can be prevented by a simple specifying operation as compared with the conventional one requiring mask specification. can do.
