Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for creating an image using a plurality of partial images prepared in advance, and particularly to a technique for changing the drawing color of the partial image.
[0002]
[Prior art]
One of the methods for creating an image is a sprite method. This sprite method is a method of creating an image by combining (combining) partial images such as sprites (objects) and backgrounds. This sprite method has an advantage that an image can be created at a higher speed than other methods. For this reason, it is widely used in devices that require high-speed image creation, such as video game machines.
[0003]
In the creation (drawing) of images by the sprite method, priority is usually set for each partial image, and the partial images are stacked in order from the lowest priority to the higher priority according to the priority set for each partial image ( To be synthesized). In an image created by this combining method, a partial image with a higher priority is shaped to hide a partial image with a lower priority, and the partial image is alternatively displayed on the image. In addition, there is a synthesis method for expressing a partial image hidden in a partial image having a higher priority by mixing the overlapping portions of the partial images at a ratio corresponding to the priority, for example.
[0004]
In a conventional image creating apparatus employing such a sprite method, a desired image can be created by selecting a partial image to be drawn, its position, and the drawing color of the partial image. In addition, for example, animation reproduction can be performed by preparing a plurality of partial images having different shapes little by little and displaying the plurality of partial images by performing time management.
[0005]
[Problems to be solved by the invention]
Even with the above-described conventional image creating apparatus, the user can create an arbitrary image and further an image for animation (moving image) reproduction. It is very common to change a part of the created image, for example, the drawing color. However, since the change must be made for each created image (partial image), many images form one group and used for those images, such as an image for animation (movie) playback. When there are a large number of partial images to be displayed, the drawing color must be changed for each partial image for which the drawing color is desired to be changed. However, the operation is very troublesome and it takes a long time to complete the operation.
[0006]
Normally, the drawing color of a partial image is selected by designating a desired drawing color and a partial image (or part thereof) to be changed to the drawing color in a state where a partial image to be changed is displayed. Is done. Therefore, for each partial image whose drawing color is to be changed, operations such as display of the partial image, designation of the drawing color, and a location where the drawing color is changed must be performed.
[0007]
In addition, the conventional image creating apparatus has been configured to set different modes for displaying the created image (including display as an animation (moving image)) and creating the image. For this reason, when the drawing color is changed for an image for animation reproduction (partial image), the mode must be switched every time the image is changed, which makes the above problem more serious. I was letting.
[0008]
Problems such as cumbersome operations (poor operability) and time-consuming work give a bad impression to the user and are a major factor in reducing product sales. A solution was strongly desired.
[0009]
An object of the present invention is to make it possible to easily and quickly create an image desired by a user.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>
・ Overall configuration of circuit and its operation
FIG. 1 is an overall circuit configuration diagram of a system to which the first embodiment is applied. The system shown in FIG. 1 includes a television 108 and an image creating apparatus that is used by being connected to the television 108.
[0028]
As shown in FIG. 1, this system includes a CPU 101 that controls the entire system, a program / data ROM 102 that stores control programs, various data, and the like, a work RAM 103 that the CPU 101 mainly uses for work, and a CPU 101. Input device 104, VDP (video display processor) 105 that performs image processing using image data stored in program / data ROM 102, sprite (object), and images of each partial image in the background ( An SRAM (static RAM) 106 storing graphic data, an encoder 107 for converting an RGB analog video signal output from the VDP 105 into an NTSC signal, and the television 108 are configured.
[0029]
As the input device 104, for example, a control pad as shown in FIG. 1 is employed. Various keys operated by the user are provided on the control pad 104. Specifically, a cursor movement key KY1 for moving the cursor displayed on the screen of the television 108, a start / stop key KY2 for instructing start / stop of animation reproduction, and an image to be reproduced by animation are the first images. A reset key KY3 for returning to the original position, a determination key KY4 for confirming the contents selected in the creation of the image, a forward frame advance key KY5 that advances the image to be displayed as an animation by one frame in the order direction (forward direction), And a reverse frame feed key KY6 for returning one frame in the reverse direction.
[0030]
An outline of the operation in the above configuration will be described.
The CPU 101 executes a control program read from the program / data ROM 102 to detect a key operation performed on the control pad 104 and control the VDP 105 while using the work RAM 103.
[0031]
The program / data ROM 102 stores image (graphic) data of sprites (objects) constituting the image and background partial images. The sprite (object) is a part for mainly expressing something that moves (including a change in shape), and the other background is a part for expressing the background. The CPU 101 transfers the image (graphic) data stored in the ROM 102 to the VDP 105, and causes the VDP 105 to store the image (graphic) data in the SRAM 106. The CPU 101 determines image (graphic) data to be transferred to the VDP 105 based on predetermined settings, details of operations performed on the control pad 104 by the user, and the like.
[0032]
The VDP 105 to which the image (graphic) data has been transferred from the CPU 101 stores the transferred image (graphic) data in the SRAM 106 in a predetermined format. After the image (graphic) data transferred from the CPU 101 is stored in the SRAM 106, an RGB analog video signal of an image to be displayed is generated for each scanning line using the image (graphic) data stored in the SRAM 106.
[0033]
The RGB analog video signal generated by the VDP 105 is output to the encoder 107. The encoder 107 converts the video signal into an NTSC video signal, which is a television standard, and outputs it to the television 108 in order to display an image represented by the video signal on the screen of the television 108. The television 108 renders an image on the screen by raster scanning the screen.
・ Configuration and operation of VDP105
FIG. 2 is a configuration diagram of the VDP 105.
[0034]
As described above, the VDP 105 controls screen display on the television 108 by generating RGB data of an image to be displayed. The configuration includes the following.
[0035]
First, the CPU interface unit 201 controls an interface at the time of data transfer with the CPU 101.
The SRAM interface unit 202 is an interface when the object generator unit 203 and the background generator unit 205 described later access sprite (object) or background (background) image (graphic) data stored in the SRAM 106. Control. Also, the sprite (object) and background image (graphic) data transferred from the CPU 101 are received via the CPU interface unit 201 and the data bus 214, and the CPU 101 designates them via the CPU interface unit 201 and the address bus 213. It is stored in the SRAM 106 according to the address.
[0036]
The object generator unit 203 and the background generator unit 204 are connected to the sprite (object) arranged at the display coordinates of each dot in the next horizontal display period from the SRAM 106 or the background for each horizontal period (see FIG. 13). The ground image (graphic) data is read and stored in each internal buffer.
[0037]
An object attribute memory (OAM) unit 205 stores display coordinates of sprites (objects) stored in the SRAM 106. The display coordinates correspond to the timing when the object generator unit 205 reads the image (graphic) data of the sprite (object) from the SRAM 106 via the SRAM interface unit 202. The object generator unit 203 reads image (graphic) data of the target sprite (object) from the SRAM 106 via the SRAM interface unit 202 according to the display coordinates of each sprite (object).
[0038]
The image (graphic) data is prepared as a collection of color codes indicating the drawing color of each dot, for example. The priority controller unit 206 assigns one of the color codes output from the object generator unit 203 or the background generator unit 204 for each dot corresponding to each horizontal display period to a predetermined priority ( Select according to (priority) and output.
[0039]
The color look-up table unit 207 stores R (red), G (green), and B (blue) digital data (RGB data) assigned to each color code in separate storage areas, and a priority controller unit. The RGB data assigned to the color code output by 206 is selected and output to the RGB D / A converter 208.
[0040]
The RGB D / A conversion unit 208 converts the RGB digital data output from the color lookup table unit 207 into an RGB analog video signal and outputs the RGB analog video signal.
The oscillator unit 209 generates various clocks necessary for each unit of the VDP 105 to operate.
[0041]
The horizontal / vertical synchronization counter unit 210 is a counter circuit for generating a horizontal synchronization counter value (horizontal synchronization signal) and a vertical synchronization counter value (vertical synchronization signal) necessary for image display in accordance with a clock output from the oscillator unit 209. is there.
[0042]
The decoder unit 211 decodes the horizontal synchronization counter value and the vertical synchronization counter value from the counter value output from the horizontal / vertical synchronization counter unit 210 and supplies the decoded value to each unit in the VDP 105.
[0043]
The video signal generator unit 212 generates a video signal required by the encoder 107 from the horizontal synchronization counter value and the vertical synchronization counter value output from the decoder unit 211, and supplies the video signal to the encoder 107.
[0044]
Next, a schematic operation of the VDP 105 having the above configuration will be described.
As shown in FIG. 3, the VDP 105 according to the present embodiment uses images represented by image (graphic) data output from the generator units 203 to 204 as virtual display surfaces, and superimposes these display surfaces. In this way, a single display screen (image) is formed.
[0045]
In FIG. 3, the background plane is created by the background generator unit 204, and the object plane, blowing plane, and icon plane, which are other display planes, are created by the object generator unit 203. These display surfaces are arranged in the order of the background surface, the object surface, the blowing surface, and the icon surface from the back to the front.
[0046]
The priority of each display surface is set higher for the front display surface. The priority controller unit 206 selects one of the image (graphic) data (color code) output from the generator units 203 to 204 for each dot according to the priority set on each display surface. And outputs it to the color lookup table unit 207. As a matter of course, this selection is performed among the generator units 204 to 206 that output color codes that are symmetrical to the selection. Thereby, each display surface is synthesized in such a way that a display surface with a high priority hides a display surface with a lower priority.
[0047]
The background is assigned to the background, the object to be moved on the display screen is assigned, the balloon containing letters is assigned to the balloon, and the icons have various icons necessary for image creation. Assigned. Specifically, as shown in FIG. 3, a background object and a character are assigned to the object plane, and a palette change icon, a palette icon group, and a cursor icon are assigned to the icon plane. The following description will be made on the assumption that the partial images shown in FIG. 3 are assigned to the respective display surfaces. This is to facilitate understanding by making the description concrete. In addition, the parts arranged on the display surface are expressed as partial images when they are not specified.
[0048]
In the present embodiment, partial images assigned to object planes and balloon planes, that is, characters, background objects, presence / absence display of balloons, and drawing colors of partial images to be displayed are designated for one screen. Image creation is performed. Although a detailed description is omitted, the selection of the partial image to be displayed is performed by, for example, displaying the name of the partial image that can be displayed (assigned to the icon surface), and then the user presses the cursor key KY1, the decision key KY4, It is done by operating.
[0049]
In the present embodiment, in addition to the image (graphic) data of these partial images, data for reproduction as so-called animation for operating these partial images is stored in the program / data ROM 102.
[0050]
4A and 4B are configuration diagrams of data related to character display. FIG. 4A shows an example of the configuration of data for character display, and FIG. These are data stored in the program / data ROM 102.
[0051]
The character display data includes animation data and image (graphic) data.
The animation data in FIG. 4A indicates an image (graphic) data number that is a number assigned to the image (graphic) data and a time during which the image (graphic) data of the image (graphic) data number is displayed. It consists of waiting time. The waiting time is prepared as a value when expressed in a predetermined time unit. <Return to the beginning> command of data # 16 means returning to the first data # 0 of animation data.
[0052]
The movement amount data shown in FIG. 4B includes movement amounts in the X direction and Y direction that the character moves from the previous display position, and a waiting time. These are data for managing the display position of the character. On the other hand, the initial position data is data indicating the initial display position of the character. It consists of an initial X coordinate, a Y coordinate, and a waiting time until the movement amount data is first added.
[0053]
The data shown in FIG. 5A and FIG. 5B are stored in the ROM 102 as background data, which is another partial image to be operated, and display data for balloons. The data structure shown in FIGS. 5A and 5B is basically the same as that of the character shown in FIG. However, in the animation data of the background object in FIG. 5A, there is a <not display> command of data # 0 that does not exist in the animation data of other partial images. This <not display> command is a command for displaying the background of the background surface as it is without arranging the background object on the object surface. In the present embodiment, this <not display> command expresses how the smoke changes between the two prepared background objects and the background portion masked by these background objects.
[0054]
The drawing color of the partial image can be changed by selecting one palette icon from the palette icon group shown in FIG. 3 and specifying the portion (one area constituting the partial image) to be drawn with the selected palette icon. (Set). The palette icon is selected by moving the cursor icon to the position of the desired palette icon and then operating the enter key KY4. The part for which the drawing color is desired to be changed is designated by operating the enter key KY4 after moving the cursor icon to that part.
[0055]
In the present embodiment, a plurality of palette icon groups (pallets) are prepared so as to meet various user requests. The palette change icon is for instructing to change the palette icon group (pallet) to be displayed. Each time the palette change icon is clicked, the palette (pallet icon group) is cyclically switched in a predetermined order. Is displayed. The drawing color data to be displayed for each palette (pallet icon group) is stored in the ROM 102 in the format shown in FIG. 6 (in the figure, the numbers indicated with # are palette numbers). The ROM 102 also stores character data to be displayed in the balloon frame.
[0056]
These various data stored in the ROM 102 are read out by the CPU 101 in accordance with the contents designated by default or the contents designated by operating the control pad 104 by the user. When the CPU 101 reads out these data, the CPU 101 sends the data to the VDP 105 as it is or according to the type of the data.
[0057]
Image (graphic) data sent from the CPU 101 to the VDP 105 is sent to the SRAM 106 via the CPU interface unit 201, the data bus 214, and the SRAM interface unit 202. The SRAM 106 stores the image (graphic) data sent from the CPU 101 in the format shown in FIG. 7 at the address designated by the CPU 101 via the CPU interface unit 201, the address bus 213, and the SRAM interface unit 202.
[0058]
The position where the partial image excluding the background is arranged (displayed) is controlled by setting the coordinate position. The CPU 101 generates data (attribute data) indicating an attribute such as a coordinate position for displaying a partial image (image (graphic) data) stored in the SRAM 106 and sends the data to the VDP 105. The VDP 105 sends this attribute data to the OAM unit 205 via the CPU interface unit 201 and the data bus 214. The OAM unit 205 stores the sent attribute data in the format shown in FIG. 7 at the address specified by the CPU 101 via the CPU interface unit 201 and the address bus 213.
[0059]
As shown in FIG. 7, the image (graphic) data of each partial image and its attribute data have predetermined areas for storing them, and are stored in association with each other. In addition to the priority of the display surface to which each partial image is assigned, the priority within the same display surface is set. The priority in the same display surface is controlled by the position stored in the OAM unit 205 (SRAM 106). In FIG. 7, the higher the priority, the higher the priority. Specifically, on the balloon surface, the balloon character has a higher priority than the balloon frame, and on the icon plane, a higher priority is set in the order of the cursor icon, palette change icon, and palette icon group.
[0060]
As shown in FIG. 7, the attribute data of the partial image includes a left / right reversal flag indicating whether or not the partial image is to be displayed horizontally reversed, and a character for identifying the partial image in the SRAM 106 corresponding to the attribute data. It consists of a number (represented by a character #N (N is an integer) in the figure) and X and Y coordinates for displaying the partial image.
[0061]
The object generator unit 203 accesses the SRAM interface unit 202 at each timing divided in time in each horizontal period. At this time, the object generator unit 203 calculates the timing for storing the image (graphic) data read from the SRAM 106 in the internal line buffer based on the attribute data stored in the OAM unit 205, and the image is generated at that timing. (Graphic) data is stored in a line buffer for each display surface. In these line buffers, image (graphic) data of partial images is stored with priority given to the high priority within the same display surface.
[0062]
The other background generator unit 204 should access the SRAM interface unit 202 at each time-divided timing within each horizontal period and display it from the SRAM 106 within the next horizontal period, separately from the object generator unit 203. One line of background image (graphic) data is read out and stored in an internal line buffer.
[0063]
In this way, in the three line buffers in the object generator unit 203, image (graphic) data (color code) for the next one line to be arranged on the object plane, the blowout plane, and the icon plane, respectively, for each horizontal period Stored every time. The line buffer in the other background generator unit 204 stores image (graphic) data (color code) for the next line to be arranged on the background surface for each horizontal period.
[0064]
The object generator unit 203 and the background generator unit 204 receive the horizontal synchronization counter value output from the horizontal / vertical synchronization counter unit 210, read out the color code corresponding to the count value from the internal line buffer, and execute the priority controller The data is output to the unit 206.
[0065]
When the priority controller unit 206 inputs the color code for each line buffer (display surface) output from each of the generator units 203 and 204, one color code is selected from among the priority levels set for each display surface. Is output to the CLT unit 207.
[0066]
As described above, the CLT unit 207 stores the RGB data assigned to each color code in different storage areas, and converts the RGB data set in the color code output by the priority controller unit 206 into RGB data. The data is output to the D / A converter 208. In the present embodiment, as shown in FIG. 8, a color code is assigned to each type of partial image, and the color codes of the respective parts (areas) constituting the partial image are all unified to the same value ( (Refer to FIGS. 10-12).
[0067]
In the animation reproduction by the sprite method, a method of realizing the operation of the partial image by changing the display position, the shape, or the like is used. In this embodiment, as can be seen from FIG. 4 and FIG. 5, by preparing a plurality of partial images classified as the same type, switching the display of the partial images and moving the display position thereof. The operation of the partial image is realized.
[0068]
In the case of performing animation reproduction, a drawing color is set for each of the prepared partial images. Therefore, conventionally, in order to change the drawing color of a partial image, the drawing color set for each partial image has to be changed, which requires a very troublesome work.
[0069]
In the present embodiment, the present invention is applied to a system that employs a method of generating RGB data of each dot constituting a display screen (after combining each display surface) using the CLT unit 207. Is. For this reason, as shown in FIG. 8, a color code is assigned to each type of partial image, and RGB data set for each color code is stored in a storage area assigned to the color code in the CLT unit 207. The drawing color of the partial image can be changed at once for each type. This simplifies the work required for changing the drawing color and allows the user to finish the work in a short time.
[0070]
10 to 12 show color codes assigned to each region (main part) constituting each partial image assigned to each display surface (background surface, object surface, balloon surface, icon surface).
[0071]
In the present embodiment, characters, background objects, and the like are also composed of a plurality of areas and are expressed by a plurality of drawing colors. For this reason, a plurality of color codes are assigned for each type of partial image.
[0072]
FIG. 10 is a diagram showing the color code assigned to each part constituting the character. As shown in FIG. 10, the character is divided into a plurality of parts (regions) such as hair, skin, and clothes. In the present embodiment, in order to express the action of the character, a plurality of (8 in total) characters prepared in such a plurality of portions (areas) are prepared. However, in each character having a different shape, the color code assigned to the hair is 2, the color code assigned to the skin is 3, and the value of the color code assigned to each area constituting the character is unified to the same value. ing. These color codes serve as identifiers indicating the respective parts (areas) constituting the character.
[0073]
In addition to the prepared background object (see FIG. 5A), the background object masked by the background object is used to express the change (swing) of the smoke. For this reason, as can be seen from FIGS. 8 and 11, a color code is not assigned to the background object, but the color code assigned to the background is shared by the background object. In the background object, a color code 55 is assigned to smoke, a color code 56 is assigned to wood, and a color code 54 is assigned to the roof. Further, as shown in FIGS. 8 and 12, color codes are also assigned to the balloons, palette icons, palette icons of the palette icon group, and cursor icons.
[0074]
The background is divided into a plurality of parts (regions) such as clouds, mountains, ponds, etc., in addition to smoke, trees, roofs, etc. common to the background object. A color code 50 is assigned to the cloud, a color code 51 is assigned to the mountain, and a color code 52 is assigned to the pond. Also in the background and the background object, the color code assigned to each part (area) constituting it becomes an identifier indicating the part (area) to which the part is assigned. Note that a color code 1 in which black is set as the drawing color is assigned to the contour line indicating the boundary of each part (region) regardless of the type of the partial image.
[0075]
The drawing color of each part (area) constituting each partial image is designated by the user. In order to respond to the designation of the drawing color by the user, the RGB data stored in the CLT unit 207 is rewritten. The rewriting is realized by writing the RGB data sent from the CPU 101 via the CPU interface unit 201 and the data bus 214 to the address designated by the CPU 101 via the CPU interface unit 201 and the address bus 213. Thereby, each partial image is expressed by the drawing color designated by the user, and a display screen desired by the user is created.
[0076]
As is well known, the television 108 renders an image by raster scanning the screen. Therefore, the VDP 105 outputs an RGB analog video signal corresponding to the scanning (frame period).
[0077]
The output of the video signal corresponding to the scanning of the television 108 is such that the horizontal synchronization counter value and the vertical synchronization counter value output from the decoder unit 211 are set as a horizontal synchronization signal and a vertical synchronization signal, respectively, and each part of the VDP 105 is set to these counter values. It is realized by operating in response. FIG. 13 is an explanatory diagram of screen display timing. This represents the relationship between each counter value and the display coordinates of the dot indicated by that value, and the operation of each part of the VDP 105 is controlled by each counter value.
[0078]
As shown in FIG. 13, a period in which the horizontal synchronization counter value output from the decoder unit 211 changes from 000h to 2FFh ("h" indicates a hexadecimal number) is one horizontal period, of which 256 counts from 000h to 0FFh A period corresponding to one horizontal synchronization counter value is a horizontal display period for one line of 256 dots, and a period corresponding to the other horizontal synchronization counter values is a horizontal blank period. In addition, a period in which the vertical synchronization counter value output from the decoder unit 211 changes from 000h to 1FFh is one vertical period, and this is a display period for one screen (field) on the television 108. In this vertical period, a period corresponding to 224 counts of vertical synchronization counter values from 000h to 0DFh is a vertical display period of 224 lines in the vertical direction, and a period corresponding to other vertical synchronization counter values is a vertical blank period.
[0079]
From the CLT unit 207 to the RGB value D / A conversion unit 208, every time the horizontal synchronization counter value is counted up, one set (1 dot) of RGB data is output.
[0080]
The setting and transfer of various data from the CPU 101 to the SRAM 106 or the object attribute memory (OAM) unit 205 is executed, for example, in each vertical blank period, thereby changing the display screen every moment. In the present embodiment, rewriting of RGB data stored in the CLT unit 207 is performed using a vertical blank period.
Detailed operation of CPU 101
First, the animation reproduction operation of the CPU 101 will be specifically described with reference to FIGS. 9, 14, and 15. FIG. FIG. 15A shows animation data, initial position data, and movement amount data for a character, and FIG. 15B shows animation data for a background object. These are data for managing the actions of the character and the background object, respectively. FIG. 14 is a timing chart showing an operation example as an animation. This shows how a character and a background object are expressed in motion when animation reproduction is performed with the data shown in FIG.
[0081]
FIG. 9 is a data configuration diagram of the work RAM 103. The CPU 101 performs animation reproduction while using the work RAM 103 as a work area. FIG. 9 shows the configuration of various management data stored in the work RAM 103 by the CPU 101 for performing animation reproduction.
[0082]
As shown in FIG. 9, the management data is divided for each partial image.
The character management data includes a movement amount counter, a movement amount data number, an animation counter, and an animation data number. The movement amount counter and the movement amount data number are data for managing the movement of the character. In the movement amount data in FIG. 15A, the movement amount counter has a waiting time of data # 2, a movement amount data number. Is set with the data number currently being processed (except for data # 2).
[0083]
The animation counter and the animation data number are data for managing the character to be displayed. In FIG. 15A, the animation counter is a waiting time, and the animation data number is the character currently displayed (image (graphic)). Number assigned to (data) is set.
[0084]
The background object management data includes an animation counter and an animation data number. In the animation counter and the animation data number, the waiting time in the animation data in FIG. 15B and the data number currently being processed (excluding the waiting time) are set, respectively. The balloon management data has the same configuration as the background object management data.
[0085]
The animation management data is data for managing animation reproduction as a whole, and includes an animation mode and an animation frame number.
[0086]
The animation mode is data indicating whether animation reproduction is currently being performed or whether the reproduction is stopped (during pause). The animation frame number is data indicating the number of frames that have elapsed since the start of animation reproduction.
[0087]
The frequency of the animation frame is 60 as shown in FIG. The frame frequency of the NTSC system is 30, and one frame is composed of two fields, so one field corresponds to one animation frame. The waiting time prepared for each partial image is a value using this one animation frame as a reference time. The CPU 101 recognizes the time of one animation frame, for example, by inputting the vertical synchronization counter value (see FIG. 13) output from the horizontal / vertical synchronization counter unit 210 of the VDP 105 by the timer function provided therein. .
[0088]
When performing animation playback, for example, when the CPU 101 sets a waiting time in the animation counter of the character management data, the set value is decremented in accordance with the progress of the animation frame. Data in the animation data in the program / data ROM 102 indicated by the number is read (see FIG. 4A), and the character (image (graphic) data) to be displayed next is specified. After specifying the character (image (graphic) data), the animation counter sets a waiting time for displaying the specified character (image (graphic) data), and the animation data number is further next. The data number in the animation data in which the number of the character (image (graphic) data) to be displayed is stored is set. The other counters and data numbers are used in the same manner as described above.
[0089]
In FIG. 15A, all waiting times (data # 1, # 3,..., # 15) in the animation data are 6, and in the movement amount data, the X direction movement amount is 1, and the Y direction movement amount. Is 0 and the waiting time is 1. For this reason, as shown in FIG. 14, the character image (graphic) data is switched every six animation frames, and the display position is moved one by one in the positive direction of the X direction every animation frame. The movement amounts in the X direction and the Y direction are values based on, for example, dots on the display screen. When the movement amount 1 corresponds to 1 dot, the character moves 1 dot every time one animation frame period (1/60 seconds) elapses.
[0090]
On the other hand, in the background object, all waiting times in the animation data are 8 as shown in FIG. For this reason, as shown in FIG. 14, the display (including non-display) of the background object is switched every 8 animation frames.
[0091]
Explanation of processing flow
The operation of the CPU 101 will be described in detail with reference to the operation flowcharts shown in FIGS. Various operation flowcharts are realized by the CPU 101 executing a control program stored in the program / data ROM 102.
[0092]
FIG. 16 is an operation flowchart of the entire process.
When the system power is turned on, first, the initial process of step 1601 is executed. This initial processing is processing for initial setting of the VDP 105 and the like. By executing this processing, the initial screen is displayed on the television 108. Details of the processing will be described later.
[0093]
When the initial processing in step 1601 is completed, next, various keys on the control pad 104 are scanned, and processing for capturing information on the operation states of these various keys is performed (step 1602). When the process of step 1602 is completed, the process proceeds to step 1603.
[0094]
In step 1603, the type of the key that is currently operated is determined from the operation state information of the various keys captured in step 1602. If it is determined in step 1603 that there is no operated key, the process proceeds to step 1619. If it is determined that any key is operated, the processing of steps 1604 to 1618 is executed according to the determination result.
[0095]
If it is determined in step 1603 that the cursor movement key KY1 has been operated, the process proceeds to step 1604. The cursor movement key KY1 includes up / down / left / right keys. In step 1604, the position where the cursor icon is to be displayed next is calculated by performing an operation according to the type of the key operated with the cursor movement key KY1 with respect to the current display position (XY coordinate) of the cursor icon. . The newly calculated display position (XY coordinates) is sent to the OAM unit 205 shown in FIG. 2 as attribute data of the cursor icon in step 1620 described later. Thus, the cursor icon moves on the display screen following the operation performed by the user on the cursor movement key KY1. After the process of step 1604 is completed, the process proceeds to step 1619.
[0096]
If it is determined in step 1603 that the enter key KY4 has been operated, the process proceeds to step 1605. The determination key KY4 is a key for the user to instruct execution of an operation for realizing desired contents as described above. The processing of steps 1606 to 1617 following step 1605 is performed according to the content instructed by the user.
[0097]
In step 1605, it is determined whether or not the cursor icon is on any palette icon in the palette icon group. If the user moves the cursor icon onto any of the displayed palette icons and then operates the enter key KY4, the determination is yes and the process moves to step 1606. Otherwise, the determination is no and the process moves to step 1607.
[0098]
The image (graphic) data for displaying the palette icon group includes a portion where the color code is 0, that is, transparent (see FIG. 8). Since this transparent part (area) is not displayed, if the cursor icon is located in that part (area), it is determined in step 1605 that the cursor icon is not located on the palette icon. . The same applies to a case where it is determined whether or not the cursor icon is positioned on another partial image.
[0099]
Whether or not the cursor icon is positioned on the palette icon is compared with, for example, the XY coordinates of the cursor icon currently stored in the OAM unit 205 and the XY coordinates of the palette icon group stored in the OAM unit 205. By doing. The same applies to a case where it is determined whether or not the cursor icon is positioned on another partial image. The XY coordinates of various partial images stored in the OAM unit 205 are also stored in the work RAM 103, and the CPU 101 reads out the XY coordinates of the corresponding partial image from the work RAM 103 and performs the above determination.
[0100]
When the user operates the enter key KY4 after moving the cursor icon on any of the displayed palette icons, the selected color code (RGB data) assigned to the palette icon is displayed as a partial image (RGB data). It becomes the drawing color that paints the part that composes it). In step 1606, a drawing color changing process is executed in which the RGB data of the color code assigned to the palette icon is used as the RGB data of the color code assigned to the cursor icon. Thereafter, the process proceeds to step 1619.
[0101]
In step 1607, it is determined whether or not the cursor icon is positioned on the palette change icon (see FIG. 3). If the user moves the cursor icon onto the palette change icon and then operates the enter key KY4, the determination is yes and the process proceeds to step 1608. Otherwise, the determination is no and the process moves to step 1609.
[0102]
The palette change icon is for the user to instruct to change the displayed palette (pallet icon group) to another palette (pallet icon group). In step 1608, a palette change process for changing the palette (pallet icon group) to be displayed is executed, and then the process proceeds to step 1619.
[0103]
In steps 1609 to 1617, processing for changing the drawing color at the position to the drawing color set in the cursor icon according to the partial image where the cursor icon is located when the enter key KY4 is operated is performed. Done.
[0104]
In step 1609, it is determined whether or not the cursor icon is positioned on the balloon character (see FIG. 12). If the user operates the enter key KY4 after moving the cursor icon over any of the balloon characters, the determination is yes and the process proceeds to step 1610. Otherwise, the determination is no and the process moves to step 1611.
[0105]
In step 1610, assuming that the user has instructed to change the color of the balloon character, color change processing for changing the balloon character to the drawing color of the cursor icon is executed. After this process is completed, the process proceeds to step 1619.
[0106]
In step 1611, it is determined whether or not the cursor icon is positioned on the balloon frame (see FIG. 12). If the user operates the enter key KY4 after moving the cursor icon within the balloon frame avoiding the balloon characters, the determination is YES and the process proceeds to step 1612. Otherwise, the determination is no and the process moves to step 1613.
[0107]
In step 1612, assuming that the user has instructed to change the color of the balloon frame, color change processing is executed to change the balloon frame to the drawing color of the cursor icon. After this process is completed, the process proceeds to step 1619.
[0108]
In step 1613, it is determined whether or not the cursor icon is positioned on the character (see FIG. 10). If the user moves the cursor icon on the character and then operates the enter key KY4, the determination is yes and the process proceeds to step 1614. Otherwise, the determination is no and the process moves to step 1615.
[0109]
In step 1614, assuming that the user has instructed to change the color of the character, color change processing is executed for changing the portion (area) of the character where the cursor icon is located to the drawing color of the cursor icon. After this process is completed, the process proceeds to step 1619.
[0110]
In step 1615, it is determined whether or not the cursor icon is positioned on the background object (see FIG. 11). If the user moves the cursor icon on the background object and then operates the enter key KY4, the determination is yes and the process proceeds to step 1616. Otherwise, the determination is no and the process moves to step 1617.
[0111]
In step 1616, assuming that the user has instructed to change the color of the background object, a color change process is executed for changing the portion (area) of the background object where the cursor icon is located to the drawing color of the cursor icon. After this process is completed, the process proceeds to step 1619.
[0112]
As described above, the background object arranged to mask a part of the background has a period during which the animation is not displayed. If the user gives an instruction to change the color of the background portion (area) masked by the background object during the period in which the background object is not displayed, the background color changing process in step 1617 is executed, and the cursor icon Change the drawing color of the displayed part. After this process is completed, the process proceeds to step 1619.
[0113]
On the other hand, if it is determined in step 1603 that any of the other keys, that is, the start / stop key KY2, the reset key KY3, the forward frame advance key KY5, or the backward frame advance key KY6 is operated, The animation mode changing process in step 1618 is executed. The animation mode changing process in step 1618 is performed in accordance with the key operated by the user. After this process is completed, the process proceeds to step 1619.
[0114]
In step 1619, animation processing for advancing animation reproduction is executed. When this process ends, a process for transferring data to be transferred to the VDP 105 generated as a result of executing the above-described steps 1604 to 1618 using the vertical blank period (see FIG. 13) is performed. After this transfer process is completed, the process returns to step 1602 and the subsequent processes are executed in the same manner.
[0115]
In this embodiment, as can be seen from the overall processing in FIG. 16 described above, the palette is changed as needed, and partial images such as cursor icons, balloons, characters, and backgrounds are changed according to the key operation provided on the control pad 104. Change the color. For this reason, the troublesome switching operation of the mode setting is avoided, and the user can change the drawing color of the partial image quickly and efficiently. In addition, since the drawing color of the partial image can be changed even during animation reproduction, it is possible to specify a color in consideration of the movement of the partial image.
[0116]
FIG. 17 is an operation flowchart of the initial process executed as step 1601 shown in FIG. By executing this initial process, an initial screen is displayed on the screen of the television 108.
[0117]
First, in step 1701, the OAM unit 205 and the like in the VDP 105 are initialized. When this initialization is completed, next, in step 1702, the animation mode is set to pause, and in the subsequent step 1703, the animation frame number is set to zero. When the processing in these steps 1702 and 1703 is executed, a value indicating 0 is set and 0 is set in the animation management data stored in the work RAM 103, that is, the animation mode and the animation frame number.
[0118]
In step 1704 following step 1703, an animation initial process is performed in which the character is arranged at the display position indicated by the initial position data in FIG. After this process is completed, the process proceeds to step 1705.
[0119]
In step 1705, an animation initial process for arranging the background object according to the animation data of FIG. 5A is executed. In step 1706 following this process, an animation initial process for arranging the balloons in accordance with the display position of the character is executed. After completing this process, the process proceeds to step 1707.
[0120]
In steps 1707 to 1711, a drawing color (RGB data) corresponding to each color code assigned to the outline, character, background, balloon, and balloon is initialized. Specifically, black is set for outlines and balloon characters, and white is set for all others. With this setting, the initial screen has a white background as a background, and the outlines and balloon characters of each partial image are drawn in black on the background.
[0121]
In steps 1712 to 1714 subsequent to step 1711, processing relating to display of the palette and the cursor icon is performed. By performing these processes, the palette (pallet icon group) and the cursor icon are initially displayed in a preset drawing color.
[0122]
First, in step 1712, 0 is set to the pallet number (see FIG. 9) which is pallet management data. In the subsequent step 1713, the selected colors (10 in total) assigned to each pallet icon with the pallet number 0 are read from the program / data ROM 102 (see FIG. 6), and these are stored in the color codes 246 to 255 of the CLT unit 207. Set as the corresponding selected color (RGB data). Thereafter, in step 1714, the drawing color of the cursor icon to which the color code 245 is assigned is set to the selected color of the color code 246 set in step 1713.
[0123]
In step 1715 following step 1714, processing for transferring image (graphic) data to be transferred to the SRAM 106 and data to be written to the OAM unit 205 and CLT unit 207 in the VDP 105 after waiting for a vertical blank period (see FIG. 13). Do. When the processing in step 1715 ends, a series of processing ends.
[0124]
In the work RAM 103, the number of image (graphic) data of each partial image to be displayed, the position at which it is displayed (arranged), and the drawing color (RGB) of the color code assigned to each part (area) constituting it Data) is stored for control management. The result of executing the processing of steps 1704 to 1714 described above is reflected in the control management data stored in the work RAM 103. The processing in step 1715 is performed based on this control management data.
[0125]
Next, with reference to FIGS. 18 to 20, each animation initial process in steps 1704 to 1706 shown in FIG. 17 will be described in detail.
First, the character animation initial process at step 1704 shown in FIG. 17 will be described with reference to the operation flowchart shown in FIG. This character animation initial processing is performed based on the animation data shown in FIG. 4, the initial position data, etc., for character management data stored in the work RAM 103 (see FIG. 9), and data stored in the OAM unit 205 in the VDP 105. This is a process for initial setting.
[0126]
First, in step 1801, the X and Y coordinates stored in the storage area assigned to the character in the OAM unit 205 are read from the program / data ROM 102, and the initial X coordinates of the character's initial position data (see FIG. 4). , Set to the initial Y coordinate. In the subsequent step 1802, the waiting time of the initial position data is set in the movement amount counter (see FIG. 9) constituting the character management data stored in the work RAM 103. Thereafter, in step 1803, 0 is set to the movement amount data number constituting the character management data. As described above, 0 indicates the data indicated by data # 0 in the movement amount data of FIG. After the movement amount data number is set to 0, the process proceeds to step 1804.
[0127]
In step 1804, character image (graphic) data to be stored in the SRAM 106 is specified from the animation data data # 0 in FIG. The specified image (graphic) data is transferred to the SRAM 106 in the process of step 1715 in FIG.
[0128]
In the subsequent step 1805, the animation data # 1 of FIG. 4A, that is, the waiting time is set in the animation counter constituting the character management data. After the setting of the waiting time is completed, in step 1806, 2 is set to the animation data number constituting the character management data. This 2 indicates the data indicated by data # 2 in the animation data of FIG. 4A as described above. After 2 is set in the animation data number, a series of processing ends.
[0129]
FIG. 19 is an operation flowchart of the background object animation initial process executed as step 1705 of FIG. Next, this animation initial process will be described in detail. This animation initial process is a process for initializing the background object management data (see FIG. 9) stored in the work RAM 103 and the data stored in the OAM unit 205 in the VDP 105, similarly to the character animation initial process.
[0130]
First, in step 1901, the animation data of FIG. 5A is read from the program / data ROM 102, and it is determined whether or not the data # 0 is a “non-display” command. If the data # 0 is a “non-display” command, the determination is YES and the process proceeds to step 1902; otherwise, the determination is NO and the process proceeds to step 1903.
[0131]
In step 1902, in order not to place the background object on the object plane, the X and Y coordinates stored in the storage area of the OAM unit 205 assigned to the background object are set to predetermined values outside the screen. After this setting is completed, the process proceeds to step 1905.
[0132]
On the other hand, in step 1903, the X and Y coordinates stored in the storage area of the OAM unit 205 assigned to the background object are set to predetermined X and Y coordinates that mask the portion (area) on the background corresponding to it. To do. In the subsequent step 1904, the number stored in the animation data data # 0 in FIG. 5A (the data # 0 has a number for specifying image (graphic) data unless it is a “non-display” command. Image (graphic) data corresponding to (stored) is specified as image (graphic) data to be transferred to the SRAM 106. After that is completed, the process proceeds to step 1905.
[0133]
In step 1905, the waiting time which is data # 1 of the animation data is set in the animation counter (see FIG. 9) constituting the background object management data stored in the work RAM 103. Thereafter, at step 1906, 2 is set to the animation data number constituting the background object management data. This 2 indicates the data indicated by data # 2 in the animation data of FIG. 5A as described above. After 2 is set in the animation data number, a series of processing ends.
[0134]
FIG. 20 is an operation flowchart of the balloon animation initial process executed as step 1706 of FIG. Next, this animation initial process will be described in detail.
[0135]
In the present embodiment, a character is moved to move the display position. For this reason, in the balloon animation initial process, the balloon and the initial display position of the balloon character are set (determined) based on the initial display position of the character determined by executing the animation initial process of the character in FIG.
[0136]
The total number of balloon characters in the present embodiment is 8, for example, as can be seen from FIG. In the processes of steps 2001 and 2002, the initial display positions are set in a predetermined order for the eight balloon characters.
[0137]
First, in step 2001, the X and Y coordinates stored in the storage area of the OAM unit 205 assigned to the balloon characters are subjected to predetermined calculation processing, for example, with respect to the initial display position (X and Y coordinates) of the character. Set to the X and Y coordinates obtained in step (1). The X and Y coordinates set by executing this step 2001 are for one character. In this step 2001, the number of executions is counted, and the X and Y coordinates of the balloon characters corresponding to the count value are set.
[0138]
In step 2002 following step 2001, it is determined whether or not the X and Y coordinates for eight characters have been set. When the X and Y coordinates are set for all the balloon characters to be displayed, the determination is YES and the process proceeds to step 2003. Otherwise, the determination is no and the process returns to step 2001.
[0139]
In step 2003, the X and Y coordinates stored in the storage area of the OAM unit 205 assigned to the balloon frame are obtained by performing predetermined arithmetic processing on the initial display position (X, Y coordinates) of the character, for example. Set to the X and Y coordinates. Thereafter, the process proceeds to step 2004.
[0140]
In steps 2004 to 2006, initial setting is performed according to the animation data of FIG. 5B read from the program / data ROM 102.
First, in step 2004, image (graphic) data to be displayed as a balloon frame is specified from the number stored as the animation data data # 0. In the following step 2005, the waiting time which is data # 1 of the animation data is set in the animation counter (see FIG. 9) constituting the blowing management data stored in the work RAM 103. Thereafter, in step 2006, 2 is set to the animation data number constituting the blowing management data. This 2 indicates the data indicated by data # 2 in the animation data of FIG. 5B as described above. After 2 is set in the animation data number, a series of processing ends.
[0141]
Next, the animation mode changing process executed as step 1618 in FIG. 16 will be described in detail with reference to the operation flowchart shown in FIG. As described above, the animation mode changing process is executed when the user operates the start / stop key KY12, the reset key KY3, the forward frame advance key KY5, or the backward frame advance key KY6.
[0142]
First, in step 2101, the type of key operated by the user is determined. Subsequent steps 2101 to 2117 are performed according to the type of key operated by the user.
[0143]
If it is determined in step 2101 that the key operated by the user is the start / stop key KY2, the process proceeds to step 2102.
In step 2102, the current animation playback state is determined from the animation mode constituting the animation management data stored in the work RAM 103.
[0144]
If it is determined in step 2102 that the animation is currently being played back, the animation mode is set to pause in step 2103, and then a series of processing ends. If it is determined in step 2102 that the animation playback is currently paused, the animation mode is set to playback in step 2104, and then a series of processing ends.
[0145]
If it is determined in step 2101 that the key operated by the user is the forward frame advance key KY5, the process proceeds to step 2105.
In step 2105, the current animation playback state is determined from the animation mode constituting the animation management data stored in the work RAM 103.
[0146]
If it is determined in step 2105 that the animation is currently being played back, the series of processing ends here. If it is determined in step 2105 that the animation playback is currently paused, the process proceeds to step 2106.
[0147]
In step 2106, the animation frame number constituting the animation management data stored in the work RAM 103 is advanced (added) by the frame advance amount.
[0148]
The frame advance amount is the number of animation frames (one frame period is 1/60 second) advanced by one operation on the forward frame advance key KY5, and the number of frames is the character or background object to be arranged (displayed). It is necessary to set the value so that at least one of the values is switched (frame-advanced). For this reason, the frame advance amount is determined from the values of the animation counters of the character management data and the background object management data, for example. As shown in FIG. 15, when the animation data of the character and the background object is set, the waiting time of the character is 6 and the waiting time of the background object is 8, so the frame advance amount is 6 to 8 (animation By setting the value between the number of frames), frame advance can be reliably realized.
[0149]
In step 2107 following step 2106, frame advance processing is performed in which the character is advanced in the forward direction according to the frame advance amount determined in step 2106. When this is completed, in the next step 2108, the frame advance processing in the forward direction is similarly executed for the background object. After the processing in step 2108 is completed, the series of processing is terminated.
[0150]
If it is determined in step 2101 that the key operated by the user is the reverse frame advance key KY6, the process proceeds to step 2109.
In step 2109, the current animation playback state is determined from the animation mode constituting the animation management data stored in the work RAM 103.
[0151]
If it is determined in step 2109 that the animation is currently being played back, the series of processing ends here. If it is determined in step 2109 that the animation playback is currently paused, the process proceeds to step 2110.
[0152]
In step 2110, the animation frame number constituting the animation management data stored in the work RAM 103 is returned (subtracted) by the frame advance amount.
[0153]
The frame advance amount is the number of animation frames (one frame period is 1/60 second) to be returned by one operation with respect to the reverse frame advance key KY6. The number of frames is the same as the frame advance amount in the forward direction described above. In addition, it is necessary to set the value so that at least one of the character to be arranged (displayed) and the background object is switched. For this reason, the frame advance amount is determined from the values of the animation counters of the character management data and the background object management data, for example. As shown in FIG. 15, when the animation data of the character and the background object is set, the waiting time of the character is 6 and the waiting time of the background object is 8, so the frame advance amount is 6 to 8 (animation By setting the value between the number of frames), frame advance in the reverse direction can be reliably realized.
[0154]
In step 2111 following step 2110, it is determined whether or not the animation frame number returned in step 2110 by the reverse frame advance amount is 0 or less. When the system power is turned on, the initial process of FIG. 17 is executed in step 1601 of FIG. 16, and 0 is set to the animation frame number. When the animation frame number is 0, the display screen on which the animation is reproduced is the initial screen. If the animation frame number is 0 or less, the determination is YES and the process proceeds to step 2114. If the number is greater than 0, the determination is NO and the process proceeds to step 2112. As will be described later, the processing after step 2114 is processing for displaying the initial screen.
[0155]
In step 2112, frame advance processing is performed to advance the character in the reverse direction according to the frame advance amount determined in step 2110. When this is completed, next, in step 2113, the frame advance process in the reverse direction is similarly executed for the background object. After the process of step 2113 is completed, the series of processes is terminated.
[0156]
If it is determined in step 2101 that the key operated by the user is the reset key KY3, the process proceeds to step 2114. In steps 2114 to 2117, as described above, a series of processes for displaying the initial screen is performed.
[0157]
First, in step 2114, the animation frame number is set to zero. Thereafter, in each process of steps 2115 to 2117, an animation initial process (see FIGS. 18 to 20) of each partial image of the character, the background object, and the balloon is executed. After these animation initial processes are finished, a series of processes is finished.
[0158]
The above-described animation mode change process is executed whenever the user operates the start / stop key KY12, the reset key KY3, the forward frame advance key KY5, or the backward frame advance key KY6 on the control pad 104. For this reason, the user can arbitrarily operate the start / stop key KY2, for example, an arbitrary display screen so that animation playback is paused in a state where a character that is easy to specify a desired color is displayed. Can be selected. As a result, for example, even in an animation in which a plurality of partial images (objects) are displayed only for a short period of time, it is possible to easily specify colors for the plurality of partial images (objects), thereby improving the work efficiency. Can do.
[0159]
When the start / stop key KY2 is operated and the animation mode is set to pause, the frame is advanced by operating the frame advance keys KY5 and KY6 to select a desired display screen. Since it can be displayed, the color designation for the partial image (object) becomes easier.
[0160]
Next, each subroutine process of steps 2107, 2108, 2112, and 2113 executed in the above-described animation mode change process of FIG. 21 will be described in detail with reference to the operation flowcharts of FIGS.
[0161]
First, with reference to the operation flowchart of FIG. 22, the character forward direction frame advance processing will be described in detail. As described above, the forward frame advance process is a process of moving the character forward in the forward direction according to the frame advance amount determined in step 2106 in FIG. The entire processing flow is such that the movement amount counter and the animation counter (see FIG. 9) constituting the character management data stored in the work RAM 103 are repeatedly decremented by the frame feed amount, and the decrement is performed once. The character movement amount and the image (graphic) data to be stored in the SRAM 106 are specified according to the value of each counter after decrementing.
[0162]
First, in step 2201, the movement amount counter is decremented. In the next step 2202, it is determined whether or not the value of the movement amount counter after the decrement is zero. If the value of the movement amount counter is greater than 0, the determination is no and the process proceeds to step 2208. Otherwise, the determination is yes and the process moves to step 2203.
[0163]
When the value of the movement amount counter becomes 0, the character is moved as described above. In step 2203, the movement amount data number constituting the character management data stored in the work RAM 103 is viewed, and the movement amount data (refer to FIG. 4B) indicated by the number is the data in the X and Y directions. The amount of movement is added to the X and Y coordinates of the current character stored in the work RAM 103, respectively. The X and Y coordinates are data indicating the display position of the character stored in the OAM unit 205 or to be stored.
[0164]
In step 2204 following step 2203, the waiting time constituting the movement amount data is set in the movement amount counter constituting the character management data. When the setting to the movement amount counter is completed, next, in step 2205, the movement amount data number is advanced (in the present embodiment, 3 is added), and the value is updated. Thereafter, the process proceeds to step 2206.
[0165]
In step 2206, it is determined whether or not the data indicated by the updated movement amount data number is a “return to the beginning” command (see FIG. 4B). If the data is a “return to the beginning” command, the determination is YES, and the process proceeds to step 2207. Otherwise, the determination is no and the process moves to step 2208. In step 2207, the movement amount data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 2208.
[0166]
Steps 2201 to 2207 described above are processes for determining the display position of the character. In subsequent steps 2208 to 2214, processing for determining a character to be displayed is performed.
[0167]
First, in step 2208, the animation counter is decremented. In the subsequent step 2209, it is determined whether or not the value of the animation counter after the decrement is zero. If the value of the animation counter is greater than 0, the determination is no and the process moves to step 2215. Otherwise, the determination is yes and the process moves to step 2210.
[0168]
When the value of the animation counter becomes 0, the character to be displayed is switched as described above. In step 2210, the animation data number constituting the character management data stored in the work RAM 103 is viewed, and an image (graphic) to be newly written to the SRAM 106 from the data in the animation data of FIG. Identify the data.
[0169]
In step 2211 following step 2210, the waiting time in the animation data corresponding to the image (graphic) data is set in the animation counter. When the setting of the waiting time to the animation counter is completed, next, in step 2212, the animation data number is advanced (in the present embodiment, 2 is added) and updated. Thereafter, the process proceeds to step 2213.
[0170]
In step 2213, it is determined whether or not the data indicated by the updated animation data number is a “return to the beginning” command (see FIG. 4A). If the data is a “return to the beginning” command, the determination is yes and the process proceeds to step 2214. Otherwise, the determination is no and the process moves to step 2215. In step 2214, the animation data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 2215.
[0171]
In step 2215, it is determined whether each counter is decremented by the frame advance amount. If the counter is not decremented by the frame advance amount, the determination is no and the process returns to step 2201. Otherwise, the determination is yes and the series of processing is terminated.
[0172]
FIG. 23 is an operation flowchart of the forward frame advance processing of the background object executed as step 2108 in FIG. Next, the background object forward direction frame advance processing will be described in detail with reference to FIG.
[0173]
As described above, this forward frame advance process is a process of frame-feeding the background object in the forward direction according to the frame advance amount determined in step 2106 in FIG. The entire processing flow is such that the animation counter (see FIG. 9) constituting the background object management data stored in the work RAM 103 is repeatedly decremented by the frame feed amount and decremented each time the decrement is performed. The image (graphic) data to be stored in the SRAM 106 is specified according to the value of the later counter.
[0174]
First, in step 2301, the animation counter is decremented. In the next step 2302, it is determined whether or not the value of the animation counter after the decrement is zero. If the value of the animation counter is greater than 0, the determination is no and the process proceeds to step 2311. Otherwise, the determination is yes and the process moves to step 2303.
[0175]
When the value of the animation counter reaches 0, the background object to be displayed is switched as described above. However, unlike a character, in the case of a background object, not only a prepared background object but also a background portion (area) masked by them is used to express a change in smoke. The portion (area) masked by the background object is used by hiding the background object.
[0176]
Therefore, in step 2303, the animation data number constituting the background object management data stored in the work RAM 103 is viewed, and the data in the animation data in FIG. 5A indicated by the number is “not displayed”. Determine whether the command. If the data is a “not display” command, the determination is yes and the process proceeds to step 2304. Otherwise, the determination is no and the process moves to step 2305.
[0177]
In step 2304, the X and Y coordinates of the background object stored in the work RAM 103 are set to values outside the screen. Thereafter, the process proceeds to step 2307. The X and Y coordinates stored in the work RAM 103 are data indicating the display position of the background object stored in the OAM unit 205 or to be stored.
[0178]
On the other hand, in step 2305, since the background object is displayed, the X and Y coordinates of the background object stored in the work RAM 103 are set to predetermined values. In the subsequent step 2306, the image (graphic) data of the background object to be displayed next is specified from the animation data number. Thereafter, the process proceeds to step 2307.
[0179]
The image (graphic) data specified in step 2306 is read from the program / data ROM 102 and transferred to the VDP 105 in step 1620 of FIG. The image (graphic) data is written into the SRAM 106 by the VDP 105.
[0180]
In step 2307, the waiting time of the image (graphic) data specified in step 2306 is set in the animation counter. In the subsequent step 2308, the animation data number is advanced (added 2), and the data number is updated. Thereafter, the process proceeds to step 2309.
[0181]
In step 2309, it is determined whether or not the data in the animation data indicated by the animation data number updated in step 2308 is a “return to the beginning” command (see FIG. 5A). If the data is a “return to the beginning” command, the determination is YES, and the process proceeds to step 2310. Otherwise, the determination is no and the process proceeds to step 2311. In step 2310, the animation data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 2311.
[0182]
In step 2311, it is determined whether or not the animation counter is decremented by the frame advance amount. If the counter is not decremented by the frame advance amount, the determination is no and the process returns to step 2301. Otherwise, the determination is yes and the series of processing is terminated.
[0183]
FIG. 24 is an operation flowchart of the character reverse frame feed process executed as step 2112 in FIG. Next, with reference to FIG. 24, the reverse frame advance processing of the character will be described in detail.
[0184]
As described above, the reverse frame advance process is a process of moving the character in the reverse direction according to the frame advance amount determined in step 2110 in FIG. The entire processing flow is such that the increment of the movement amount counter and the animation counter (see FIG. 9) constituting the character management data stored in the work RAM 103 is repeated by the frame advance amount, and each increment is performed. In addition, the character movement amount and the image (graphic) data to be stored in the SRAM 106 are specified according to the value of each counter after the increment.
[0185]
First, in step 2401, the movement amount counter is incremented. In the following step 2402, it is determined whether or not the incremented movement amount counter value has exceeded the previously set waiting time. If the value of the movement amount counter is larger than the waiting time, the determination is YES and the process proceeds to step 2403. Otherwise, the determination is no and the process moves to step 2408.
[0186]
If the value of the movement amount counter becomes larger than the set waiting time, it means that it is necessary to move the character in the reverse direction. In step 2403, the movement amount data number constituting the character management data stored in the work RAM 103 is returned (3 is subtracted), and the data number is updated. Thereafter, the process proceeds to step 2404.
[0187]
In step 2404, it is determined whether or not the updated movement amount data number is smaller than zero. If the data number is smaller than 0, the determination is yes and the process proceeds to step 2405. Otherwise, the determination is no and the process moves to step 2406. In step 2405, the value of the data number three before the “return to the beginning” command, that is, 0 is set in the movement amount data number. Thereafter, the process proceeds to step 2406.
[0188]
In step 2406, the X and Y direction movement amounts that are data in the movement amount data (see FIG. 4B) indicated by the movement amount data number are stored in the work RAM 103 in the X and Y directions of the current character. Subtract each from the coordinates. As described above, the X and Y coordinates are data indicating the display position of the character stored in the OAM unit 205 or to be stored.
[0189]
In step 2407 following step 2406, 1 is set in the movement amount counter in order to take the timing for subtracting the movement amount for moving the character in the opposite direction from the X and Y coordinates. Thereafter, the process proceeds to step 2408.
[0190]
Steps 2401 to 2407 described above are processes for determining the character display position. In subsequent steps 2408 to 2414, processing for determining a character to be displayed is performed.
[0191]
First, in step 2408, the animation counter is incremented. In the following step 2409, it is determined whether or not the incremented animation counter value has exceeded the waiting time set for it last time. If the value of the animation counter is greater than the waiting time, the determination is yes and the process proceeds to step 2410. Otherwise, the determination is no and the process moves to step 2415.
[0192]
If the value of the animation counter becomes larger than the set waiting time, it means that the character needs to be switched. In step 2410, the animation data number constituting the character management data stored in the work RAM 103 is returned (2 is subtracted), and the data number is updated. Thereafter, the process proceeds to step 2411.
[0193]
In step 2411, it is determined whether or not the updated animation data number is smaller than 0. If the data number is smaller than 0, the determination is yes and the process proceeds to step 2412. Otherwise, the determination is no and the process moves to step 2413. In step 2412, the value of the data number two before the “return to the beginning” command, ie, 14 is set in the animation data number (see FIG. 4A). Thereby, the character can be cyclically switched in the reverse order to the animation reproduction. Thereafter, the process proceeds to step 2413.
[0194]
In step 2413, image data (graphic) to be displayed as a character is specified by looking at the animation data number set in step 2410 or step 2412. In the following step 2414, 1 is set in the animation counter in order to take the timing for switching the character next time. Thereafter, the process proceeds to step 2415.
[0195]
In step 2415, it is determined whether each counter has been incremented by the frame advance amount. If the increment for the frame advance amount is not performed for each counter, the determination is no and the process returns to step 2401. Otherwise, the determination is yes and the series of processing is terminated.
[0196]
FIG. 25 is an operation flowchart of background object reverse frame advance processing executed as step 2113 of FIG. Next, with reference to FIG. 25, the background frame backward frame advance processing will be described in detail.
[0197]
As described above, the reverse frame advance process is a process of moving the background object in the reverse direction according to the frame advance amount determined in step 2110 in FIG. The overall processing flow is such that the increment of the animation counter (see FIG. 9) constituting the background object management data stored in the work RAM 103 is repeated by the frame advance amount, and every time the increment is performed, The image (graphic) data to be stored in the SRAM 106 is specified according to the counter value.
[0198]
First, in step 2501, the animation counter is incremented. In the following step 2502, it is determined whether or not the incremented animation counter value has exceeded the waiting time set for it last time. If the value of the animation counter is greater than the waiting time, the determination is yes and the processing moves to step 2503. Otherwise, the determination is no and the process moves to step 2511. If the value of the animation counter is larger than the waiting time set for it last time, it means that it is necessary to switch the display of the background object.
[0199]
In step 2503, the animation data number constituting the background object management data stored in the work RAM 103 is returned (2 is subtracted), and the data number is updated. In the following step 2504, it is determined whether or not the updated animation data number is smaller than zero. If the animation data number is smaller than 0, the determination is YES, and the process proceeds to step 2505. Otherwise, the determination is no and the process moves to step 2506. In step 2505, the animation data number is set to 2 before the data storing the “return to beginning” command, that is, 4 (see FIG. 5A). After this setting is completed, the process proceeds to step 2506.
[0200]
In step 2506, it is determined whether or not the data indicated by the animation data number updated in step 2503 or 2505 is a “do not display” command. If the data is a “not display” command, the determination is yes and the process proceeds to step 2507. Otherwise, the determination is no and the process moves to step 2508.
[0201]
In step 2507, in accordance with the “not display” command, the X and Y coordinates of the background object stored in the work RAM 103 are set to values outside the screen in order not to display (place) the background object. Thereafter, the process proceeds to step 2310.
[0202]
On the other hand, in step 2508, since the background object is displayed, the X and Y coordinates of the background object stored in the work RAM 103 are set to predetermined values. In the subsequent step 2509, the image (graphic) data of the background object to be displayed next is specified from the animation data number. Thereafter, the process proceeds to step 2510.
[0203]
The image (graphic) data specified in step 2510 is read from the program / data ROM 102 and transferred to the VDP 105 in step 1620 of FIG. The image (graphic) data is written into the SRAM 106 by the VDP 105.
[0204]
In step 2510, 1 is set in the animation counter in order to take the next timing for switching the display of the background object. After 1 is set in the animation counter, the process proceeds to step 2511.
[0205]
In step 2511, it is determined whether or not the animation counter is incremented by the frame advance amount. If the counter is not incremented by the frame advance amount, the determination is no and the process returns to step 2501. Otherwise, the determination is yes and the series of processing is terminated.
[0206]
Next, each change process executed as steps 1606, 1608, 1610, 1612, 1614, 1616, and 1617 in the overall process of FIG. 16 will be described in detail with reference to the operation flowcharts of FIGS.
[0207]
In each of these changing processes, the setting of RGB data assigned to the color code of the corresponding partial image is changed to RGB data according to the content designated by the user.

[0226]
As shown in FIG. 10, the character is composed of a plurality of portions (areas). In step 3002, the character portion (region) where the cursor icon is displayed is obtained, and the RGB data set in the cursor icon color code 245 is used as the color of the character portion (region) where the cursor icon is displayed. Set as code RGB data. The set RGB data is stored as RGB data of the color code of the CLT unit 207 in the VDP 105, and the set is converted into RGB data for each color code stored in the work RAM 103 for control management.

First, in step 3101, it is determined whether or not the color code on the background object on which the cursor icon is displayed when the user operates the enter key KY4 is 1 (outline). If the color code is 1, the series of processing is terminated. Otherwise, the processing proceeds to step 3102.
[0230]
As shown in FIG. 11B, the background object is composed of a plurality of portions (areas). In step 3102, the portion (region) of the background object on which the cursor icon is displayed is obtained, and the RGB data set in the color code 245 of the cursor icon is used as the portion (region) of the background object on which the cursor icon is displayed.

Against. After the RGB data setting is completed, a series of processing is completed.
[0231]
FIG. 32 is an operation flowchart of the background color changing process executed as step 1617 of FIG. Next, the background color changing process will be described in detail with reference to FIG.
[0232]
As described above, the background color changing process is executed when the user operates the enter key KY4 while the cursor icon is displayed on the background. This includes a case where the display position of the cursor icon when the user operates the enter key KY4 in a state where the background object is not displayed is within the area masked by the background object.
[0233]
First, in step 3201, it is determined whether or not the color code on the background on which the cursor icon is displayed when the user operates the enter key KY4 is 1 (outline). If the color code is 1, the series of processing is terminated. Otherwise, the processing proceeds to step 3202.
[0234]
As shown in FIG. 11A, the background is composed of a plurality of portions (areas). In step 3202, the background portion (region) where the cursor icon is displayed is obtained, and the RGB data set in the cursor icon color code 245 is used as the color of the background portion (region) where the cursor icon is displayed.

Against. After the RGB data setting is completed, a series of processing is completed.
[0235]
Each change process shown in FIGS. 26 to 32 is executed when the enter key KY4 is operated. For this reason, the user can set a drawing color to the cursor icon at any time and change the partial image to a desired drawing color regardless of whether or not animation reproduction is performed. Thereby, the color designation work of the partial image is simplified, and the work can be completed in a short time.
[0236]
Next, the animation process executed as step 1619 in FIG. 16 will be described in detail with reference to the operation flowchart shown in FIGS. This animation process is a process for reproducing an animation according to the animation data and movement amount data of each partial image shown in FIGS. 4 and 5 when the animation mode is being reproduced. This animation process is performed every animation frame, that is, every 1/60 seconds.
[0237]
First, in step 3301, the current animation mode is determined. This determination is performed by reading out an animation mode (see FIG. 9) constituting the animation management data stored in the work RAM 103. If the animation mode is being reproduced, the process proceeds to step 3302, and if it is paused, the series of processes is ended here.
[0238]
In steps 3302 to 3315, processing related to character display is performed. As described above, the animation process is performed for each animation frame, and the waiting time in the character's animation data, movement amount data, etc. is a value based on the animation frame period, and is stored in the work RAM 103. The movement amount counter and the animation counter constituting the character management data are decremented, and processing is performed according to the value after each decrement of each counter.
[0239]
First, in step 3302, the movement amount counter is decremented. In the next step 3303, it is determined whether or not the value of the movement amount counter after the decrement is zero. If the value of the movement amount counter is greater than 0, the determination is no and the process moves to step 3309. Otherwise, the determination is yes and the process moves to step 3304.
[0240]
When the value of the movement amount counter becomes 0, it means that it is necessary to move the character. In step 3304, the movement amount data number stored in the work RAM 103 is viewed, and the movement amount data in the X and Y directions, which is data in the movement amount data (see FIG. 4B) indicated by the number, is obtained. Are added to the X and Y coordinates of the current character stored in. The X and Y coordinates are data indicating the display position of the character stored in the OAM unit 205 or to be stored.
[0241]
In step 3305 following step 3304, the waiting time constituting the movement amount data is set in the movement amount counter constituting the character management data. When the setting of the waiting time to the movement amount counter is finished, next, in step 3306, the movement amount data number is advanced (in the present embodiment, 3 is added), and the value is updated. Thereafter, the process proceeds to step 3307.
[0242]
In step 3307, it is determined whether or not the data indicated by the updated movement amount data number is a “return to the beginning” command (see FIG. 4B). If the data is a “return to the beginning” command, the determination is YES, and the process proceeds to step 3308. Otherwise, the determination is no and the process moves to step 3309. In step 3308, the movement amount data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 3309.
[0243]
Steps 3302 to 3308 described above are processes for determining the character display position. In subsequent steps 3309 to 3315, processing for determining a character to be displayed is performed.
[0244]
First, in step 3309, the animation counter is decremented. In the following step 3310, it is determined whether or not the value of the animation counter after the decrement is zero. If the value of the animation counter is greater than 0, the determination is no and the process moves to step 3316. Otherwise, the determination is yes and the process moves to step 3311.
[0245]
When the value of the animation counter becomes 0, it means that it is necessary to switch the display of the character to be displayed as described above. In step 3311, the animation data number constituting the character management data stored in the work RAM 103 is viewed, and an image (graphic) to be newly written to the SRAM 106 from the data in the animation data of FIG. Identify the data.
[0246]
In step 3312 following step 3311, the waiting time in the animation data corresponding to the image (graphic) data is set in the animation counter. When the setting of the waiting time to the animation counter is completed, next, in step 3313, the animation data number is advanced (in the present embodiment, 2 is added) and updated. Thereafter, the process proceeds to step 3314.
[0247]
In step 3314, it is determined whether the data indicated by the updated animation data number is a “return to the beginning” command (see FIG. 4A). If the data is a “return to the beginning” command, the determination is yes and the process proceeds to step 3315. Otherwise, the determination is no and the process moves to step 3316. In step 3315, the animation data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 3316.
[0248]
In steps 3316 to 3325, processing relating to display of the background object is performed. Since the animation process is performed for each animation frame, the animation counter (see FIG. 9) of the background object management data stored in the work RAM 103 is decremented, and the animation counter value after the decrement is obtained. It is done according to the contents.
[0249]
First, in step 3316, the animation counter is decremented. In the subsequent step 3317, it is determined whether or not the value of the animation counter after the decrement is zero. If the value of the animation counter is greater than 0, the determination is no and the process proceeds to step 3326 in FIG. Otherwise, the determination is yes and the process moves to step 3318.
[0250]
When the value of the animation counter becomes 0, it means that it is necessary to switch the display of the background object to be displayed as described above. In addition, there is a period during which the background object is not displayed during animation playback. Therefore, in step 3318, the animation data number constituting the background object management data stored in the work RAM 103 is viewed, and the data in the animation data in FIG. 5A indicated by the number is “not displayed”. Determine whether the command. If the data is a “not display” command, the determination is yes and the process proceeds to step 3319. Otherwise, the determination is no and the process moves to step 3320.
[0251]
In step 3319, in order to hide the background object, the X and Y coordinates of the background object stored in the work RAM 103 are set to values outside the screen. Thereafter, the process proceeds to step 3322. The X and Y coordinates stored in the work RAM 103 are data indicating the display position of the background object stored in the OAM unit 205 or to be stored.
[0252]
On the other hand, in step 3320, since the background object is displayed, the X and Y coordinates of the background object stored in the work RAM 103 are set to predetermined values. In the subsequent step 3321, the image (graphic) data of the background object to be displayed next is specified from the animation data number. Thereafter, the process proceeds to step 3322.
[0253]
The image (graphic) data specified in step 3321 is read from the program / data ROM 102 and transferred to the VDP 105 in step 1620 of FIG. The image (graphic) data is written into the SRAM 106 by the VDP 105.
[0254]
In step 3322, the waiting time of the image (graphic) data specified in step 3321 is set in the animation counter. In the following step 3323, the animation data number is advanced (2 is added), and the data number is updated. Thereafter, the process proceeds to step 3324.
[0255]
In step 3324, it is determined whether or not the data in the animation data indicated by the animation data number updated in step 3323 is a “return to the beginning” command (see FIG. 5A). If the data is a “return to the beginning” command, the determination is yes and the process proceeds to step 3325. Otherwise, the determination is no and the process proceeds to step 3326 in FIG. In step 3325, the animation data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 3326 in FIG.
[0256]
In steps 3326 to 3335 shown in FIG. 34, processing relating to display of balloons is performed. By performing these processes, the display switching of the balloon frame based on the animation data of FIG. 5B is realized.
[0257]
First, in step 3326, the X and Y coordinates stored in the storage area of the OAM unit 205 assigned to the balloon characters are predetermined with respect to the next display position (X, Y coordinates) of the character determined in step 3304, for example. It is set to the value obtained by performing the arithmetic processing. The X and Y coordinates set by executing this step 3326 are for one character. In this embodiment, since eight balloon characters can be displayed, in this step 3326, the number of executions is counted, and the X and Y coordinates of the balloon characters corresponding to the count value are set.
[0258]
In step 3327 following step 3326, it is determined whether or not the X and Y coordinates for 8 characters have been set. When the X and Y coordinates are set for all the balloon characters to be displayed, the determination is YES and the process proceeds to step 3328. Otherwise, the determination is no and the process returns to step 3326.
[0259]
In step 3328, the X and Y coordinates stored in the storage area assigned to the balloon frame of the OAM unit 205 are set to the next display position (X, Y) determined in step 3304 as in the case of the balloon character, for example. Set to a value obtained by performing predetermined arithmetic processing on (coordinates). Thereafter, the process proceeds to step 3329.
[0260]
Steps 3326 to 3328 described above are processes related to display of balloon characters. In subsequent steps 3329 to 3335, processing relating to display of the blowing frame is performed.
[0261]
First, in step 3329, the animation counter (see FIG. 9) stored in the work RAM 103 as one of the blowing management data is decremented. In the following step 3330, it is determined whether or not the value of the animation counter after the decrement is zero. If the value of the animation counter is greater than 0, the determination is no and the process moves to step 3336. Otherwise, the determination is yes and the process moves to step 3331.
[0262]
When the value of the animation counter becomes 0, it means that it is necessary to switch the display of the blowing frame to be displayed as described above. In step 3331, the animation data number constituting the blowing management data stored in the work RAM 103 is viewed, and the image (graphic) to be newly written to the SRAM 106 from the data in the animation data of FIG. 5B indicated by the number. Identify the data.
[0263]
In step 3332 following step 3331, the waiting time in the animation data corresponding to the image (graphic) data is set in the animation counter. When the setting of the waiting time to the animation counter is finished, next, in step 3333, the animation data number is advanced (added 2) and updated. Thereafter, the process proceeds to step 3334.
[0264]
In step 3334, it is determined whether or not the data indicated by the updated animation data number is a “return to the beginning” command (see FIG. 5B). If the data is a “return to the beginning” command, the determination is yes and the process proceeds to step 3335. Otherwise, the determination is no and the process moves to step 3336. In step 3335, the animation data number is set to the top data number, that is, 0 in accordance with the command. Thereafter, the process proceeds to step 3336.
[0265]
In step 3336, the animation frame number stored in the work RAM 103 as one piece of animation management data is incremented. After the increment of the animation frame number is finished, the series of processes is finished.
[0266]
As described above, after the animation process which is step 1619 in FIG. 16 is completed, in step 1620, image (graphic) data to be stored in the SRAM 106 is stored, and attribute data is stored in the OAM unit 205 in the VDP 105. The RGB data is stored in the CLT unit 207 in the VDP 105.

In other words, a common color code is assigned to each type of partial image. However, the present invention is not limited to this, and can be widely applied. For example, in the case of an image having a tree and a water surface in which the tree is reflected, the tree and the tree reflected in the water surface are classified as the same group, and the drawing color is changed for one of them. Accordingly, the other drawing color may be changed accordingly. In such a case, the drawing colors are not necessarily the same.
[0267]
Further, in this embodiment, in order to express the movement of the character itself, display switching of the entire character is performed, but a plurality of objects for masking a part of the character, such as a background object in the background, are prepared, The movement of the character itself may be expressed by switching the display of the object. In this case, the color code assigned to the object may be a color code corresponding to that of the character, and the application of the present invention is easy. This is the same even when a method is adopted in which a plurality of display screens are prepared and the operation of the objects in the display screen is expressed by switching the display of the display screens.
[0268]
In this embodiment, a control pad is used as the input device 104, and a user operates various keys provided on the control pad 104 to set an arbitrary drawing color to a desired partial image. However, an icon or the like may be further displayed on the display screen so that all operations can be performed only with a pointing device such as a mouse. On the contrary, all the operations may be performed with the keys provided on the control pad 104.
[0269]
In this embodiment, the user can use only palettes (pallet icon group) prepared in advance in the program / data ROM 102, but the user can freely set the drawing color (RGB data) of each palette icon. Anyway. For animation data, movement amount data, etc. that determine the operation of each partial image, for example, a plurality of them may be prepared so that the user can freely select from among them, and the user can freely set these data You may be able to do it.

<Second Embodiment>
Outline of the second embodiment
In the first embodiment described above, when the user designates a color for a partial image, the drawing color of the partial image is instantaneously reflected on the drawing color designated by the user. In the second embodiment, when the user designates a color, the drawing color of each character, background object, and background partial image is gradually changed from the original drawing color to the designated drawing color. Is. Thereby, the user can confirm the area where the drawing color is changed by designating the color. In addition, a visual effect can be provided to the user depending on the state of the change.

By executing this process, RGB data newly set as RGB data of the color data in the area specified by the user is written in the corresponding storage area of the CLT unit 207 in the VDP 105, and the displayed drawing color changes. Will do.
[0310]
In step 3811 following step 3810, the color change counter is decremented. In the following step 3812, it is determined whether or not the color change counter after decrement is zero. If the color change time has not elapsed since the user specified the color, the determination is no and the process returns to step 3806. If not, that is, if the color change time has elapsed since the user specified the color, the determination is YES and the series of processing ends.
・ Modification
In the second embodiment, the drawing color of the designated area is gradually changed to the designated drawing color, but the method of changing the drawing color is not limited to this. For example, after gradually changing the drawing color of the specified area to another drawing color that is not specified, specify it through multiple steps so that it gradually changes from that drawing color to the specified drawing color. The drawn color may be changed.
[0311]
Furthermore, instead of gradually changing the drawing color of the area to the designated drawing color, the user can set, for example, a plurality of predetermined drawing colors for the area in accordance with a predetermined order. A desired visual effect may be applied to the area designated by. In the present embodiment, partial images are grouped by type, and each partial image belonging to the group is configured so that, for example, the color code assigned to hair is unified to 2 (see FIG. 10). Since the same color code is assigned to each portion (area), it is easy to apply various visual effects.
<Third Embodiment>
Outline of the third embodiment
In the first embodiment described above, for example, taking a character as an example, the portion (area) of hair, skin, clothes, etc. constituting the character is color code 2 for hair, color code 3 for skin, There is one color code assigned to the portion (area) where the color can be specified. When such color code assignment is performed, the displayed image cannot have a stereoscopic effect. In the third embodiment, such a problem that the first embodiment has is avoided, and the display image has a three-dimensional effect.
[0312]
The configuration of the third embodiment and the operation of each part are almost the same as those of the first embodiment. For this reason, only the part changed from 1st Embodiment is demonstrated.
[0313]
FIG. 39 is a diagram showing color codes assigned to each part (region) of the partial image. FIG. 4A shows the character, and FIG. 4B shows the color code assigned to each part (area) of the background object.
[0314]
As shown in FIG. 39 (a), in the third embodiment, a three-dimensional effect is obtained by providing a gradation of light, medium, and dark on the hair of the character and assigning different color codes to each stage. Is given. For this reason, as shown in FIG. 40A, a storage area for character drawing RGB data is allocated to the CLT unit 207 in the VDP 105, and the set RGB data is stored there.
[0315]
In order to give the other background object a three-dimensional effect, the smoke is provided with a gradation of light, medium and dark as shown in FIG. 39 (b), and a different color code is assigned to each stage. Yes. For this reason, as shown in FIG. 40B, the CLT unit 207 in the VDP 105 is assigned a storage area for background drawing RGB data shared with the background object, and the set RGB data is stored there. The
[0316]
Although description of the color code assignment for the other portions is omitted, a plurality of color codes are assigned to the other portions so as to provide, for example, a three-step gradation in the pond constituting the background. .
[0317]
For example, when the hair is further divided into portions (regions) to which gradations of light, medium, and dark are given, such as a character's hair, in the first embodiment, the further divided portions The drawing color must be specified for each (area). However, in this case, the work for the user to specify a desired drawing color for each partial image becomes complicated, and the time required for the work becomes very long. The same applies to images in which many types of partial images are displayed.
[0318]
In the third embodiment, in order to avoid the above problems, color codes 2 to 4 (see FIG. 39 (a)) are assigned to each part (area) constituting the partial image, for example, in the case of character hair. The parts (areas) that are included are grouped as necessary so that if any part of the group is designated as a color, the drawing colors of the parts (areas) that belong to the group are combined. I am trying to change it.
[0319]
As described in the first embodiment, the drawing color is selected from a palette (pallet icon group). For this reason, in the third embodiment, as shown in FIG. 41, palette data in which three RGB data are set for each selected color is prepared in the program / data ROM 102. For example, the palette number is # 0. When the user designates the selected color 0 as the drawing color of the character's hair, the light RGB data of the selected color 0 is set to the color code 2, and similarly, the middle RGB data is the color code 3 and the dark RGB data. Are set to color code 4, respectively. As a result, the color designation of one part (area) in which gradation is formed can be performed by one color designation, and even in an image in which there are many color-designable areas having a stereoscopic effect, Color designation can be performed easily and in a short time.
[0320]
By the way, as explained in the first embodiment, partial images are divided into groups according to their types, and the color codes assigned to the respective parts (regions) constituting the partial images are unified to the same value. The color designation made for the image is reflected in the other partial images to which the group belongs. In order to distinguish from the group divided according to the type of partial image, hereinafter, the group divided within the partial image will be referred to as a subgroup.
[0321]
In addition, the palette data is not only prepared in advance in the program / data ROM 102, but for example, the user can arbitrarily set the drawing data, or the user can select a drawing color to be set as one selection color from among drawing colors prepared in advance. You may be able to do it.

In step 5202, for example, two RGB data of light and dark of the selected color in the pallet data specified from the pallet number, which is the pallet management data stored in the work RAM 103, and the selected color number, for example, program / data. By reading out from the ROM 102 and performing an interpolation operation using the two read out RGB data, the internal RGB data is created.
[0377]
In Step 5203 following Step 5202, the color code RGB data assigned to each part (area) constituting the subgroup to which the color-specified part (area) belongs is added to the bright data obtained in Step 5202 above. Medium and dark RGB data are set. This RGB data set is performed on the RGB data for each color code stored in the work RAM 103. After the RGB data set is completed, the series of processes is terminated.
[0378]
FIG. 53 is an operation flowchart of the background color changing process executed as step 1617 of FIG. Next, the background color changing process according to the fourth embodiment will be described in detail with reference to FIG.
[0379]
The background color changing process is executed when the user operates the enter key KY4 while the cursor icon is displayed on the background. This includes a case where the display position of the cursor icon when the user operates the enter key KY4 in a state where the background object is not displayed is within the area masked by the background object.
[0380]
First, in step 5301, it is determined whether or not the color code on the background on which the cursor icon is displayed when the user operates the enter key KY4 is 1 (outline). If the color code is 1, the series of processing is terminated. Otherwise, the processing proceeds to step 5302.
[0381]
In step 5302, for example, two RGB data of light and dark of the selected color in the pallet data specified from the pallet number, which is the pallet management data stored in the work RAM 103, and the selected color number, for example, program / data. By reading out from the ROM 102 and performing an interpolation operation using the two read out RGB data, the internal RGB data is created.
[0382]
In Step 5303 following Step 5302, the RGB data of the color code assigned to each part (area) constituting the subgroup to which the color designated part (area) belongs is added to the bright data obtained in Step 5302 above. Medium and dark RGB data are set. This RGB data set is performed on the RGB data for each color code stored in the work RAM 103. After the RGB data set is completed, the series of processes is terminated.
・ Modification
In the fourth embodiment, only the intermediate RGB data is interpolated from the light and dark RGB data of the selected color, but more RGB data is interpolated from the light and dark RGB data. You may do it. As a result, even if the number of members (number of regions) constituting the subgroup differs for each group, it is possible to flexibly cope with it.
[0383]
【The invention's effect】
As described above, according to the present invention, partial images are grouped, and the drawing colors of the partial images constituting the group are managed in an integrated manner. For this reason, only by changing the drawing color of any partial image, the drawing colors of all other partial images to which the group belongs can be changed in accordance with the change. As a result, even when image reproduction such as animation is performed, for example, the overall drawing color can be changed in a short operation and in a short time.
[0384]
Further, the present invention centrally manages the drawing color for a plurality of partial images related to the drawing color or a part thereof, so that the entire drawing color can be changed in a short operation and in a short time. Can do.
[0385]
In addition, the present invention collects a plurality of parts related to drawing colors into one group in a partial image, and when any drawing color constituting the group is changed, drawing of all the parts constituting the group is performed. The color is changed according to the changed drawing color. For this reason, it is possible to change the overall drawing color in a short operation and in a short time.
[0386]
By combining these inventions described above, a greater effect can be obtained, and the overall drawing color can be changed in fewer operations and in a shorter time.
