[0074]
Next, each process performed by the image processing unit 10 will be described with reference to the flowcharts shown in FIGS. The image processing unit 10 sequentially performs sprite processing, background processing, output color data determination processing, and color data output processing. 38 to 39 are flowcharts showing an outline of sprite processing executed by the image processing unit 10. The sprite process is a process of creating image data for one horizontal line on the display screen 14, that is, sprite color data, based on each sprite table set in the sprite surface table setting area of the memory 9.
[0075]
The image processing unit 10 determines whether or not to newly start the sprite process (step S01). When the sprite process is newly started, the execution flag F1 is 0, and a search X coordinate setting register for searching each row of each dot array on the display screen 14 shown in FIG. 10 in the horizontal direction. XR and search Y coordinate setting register YR are each set to 0 (step S02). Next, 1 is set in the execution flag F1, and the start of sprite processing is stored (step S03).
[0076]
The outline of the sprite processing will be described. The processing for determining the color output data set on the sprite surface of each dot in each row of each dot array on the display screen 14 shown in FIG. The first line, the second line, and so on are performed up to the last line, and the sprite processing for one surface of the display screen 14 is completed. The image processing unit 10 ends the sprite processing once when the sprite processing for one row is completed, and proceeds to background processing.
[0077]
After completing the initial setting process of step S02 and step S03, the image processing unit 10 proceeds to step S04 and starts a process of searching for the sprite surface having the highest display priority in the currently set sprite surface. .
[0078]
The image processing unit 10 sets the table number # 0 in the table number register TNO (step S04), searches the sprite table set in the table number register TNO, and determines whether the end flag of the table is 1 (end). It is determined whether or not (step S05).
[0079]
If the search table end flag is not 1 (end), the table number of the table number register TNO is incremented by 1 (step S06), and the process returns to step S05 to search for the next sprite table. That is, a sprite table having an end flag of 1 is searched toward a table having a higher display priority in order, such as table number # 0, table number # 1, table number # 2,. For example, in this example, since the value of the end flag of the sprite table # 6 in which the sprite surface 12G is set is set to 1, when the table number of the table number register TNO is # 6, the discrimination process in step S05 Becomes true. Note that the sprite table with the end flag of 1 has the highest display priority in the current screen display. Therefore, the sprite table with a higher rank than the sprite table with the end flag of 1 is not subject to sprite processing. That is obvious.
[0080]
When the image processing unit 10 finishes searching for the sprite surface having the highest display priority in the currently set sprite surface, the process proceeds to step S07, where one dot of the search coordinates is defined in the sprite table. The process proceeds to a process for determining whether or not the display area is included. Note that the processing related to the determination is started from a sprite table having the highest display priority with an end flag of 1 and is not included in the display area. This is a process of sequentially judging toward the table.
[0081]
The processing relating to the above determination will be described with reference to FIG. 43 as an example. In FIG. 43, the sprite surface 12a is a sprite surface with a higher display priority, and the sprite surface 12b is a sprite surface with a lower display priority than the sprite surface 12a. Each of the points a, b, c, and d is the position of the search dot.
[0082]
First, when the position of the search dot is included only in the high-order sprite surface 12a such as point a and when the display priority is higher than the sprite surface 12a and sprite surface 12a such as point b. A case will be described in which the symbols of the sprite surface 12a which is included in the region where the priority order is overlapped with the lower sprite surface 12b and consequently the display priority order is higher are displayed with priority.
[0083]
Also, as an example, the sprite surface 12a is set in the sprite table of FIG. 15 where the display start coordinates are set to the horizontal direction X1, the vertical direction is set to Y1, the array combination size is set to the horizontal direction h = 3, and the vertical direction v = 2. It shall be.
[0084]
The display range of the sprite surface 12a is that the size of one tile surface 13 is 32 dots in the horizontal direction and 32 dots in the vertical direction, so that the size of the sprite surface 12a is 0 dots to (32 × h) -1 dots in the horizontal direction. That is, 0 dots to 95 dots, 0 dots in the vertical direction to (32 × V) −1 dots, that is, 0 dots to 63 dots (see FIG. 44).
[0085]
When the display start coordinates (X1, Y1) of the sprite surface 12a are within the size of the display screen 14, 0 ≦ X1 ≦ 199 and 0 ≦ Y1 ≦ 159 are satisfied. If the display start coordinates (X1, Y1) of the sprite surface 12a do not satisfy the conditions of 0 ≦ X1 ≦ 199 and 0 ≦ Y1 ≦ 159, the display is not displayed as shown in FIG. It is excluded from the process of determining whether or not. In the following description, it is assumed that the display start coordinates (X1, Y1) of the sprite surface 12a are within the size of the display screen 14.
[0086]
If the display start coordinates (X1, Y1) of the sprite surface 12a are regarded as the coordinate base point (0, 0), the coordinates (XR, YR) of the search dots become (XR-X1, YR-Y1), and XR- If X1 = α and YR−Y1 = β, the coordinates (α, β) of the search dot are 0 when the search dot is included in the sprite surface 12a such as point a or point b in FIG. The conditions of ≦ α ≦ 95 and 0 ≦ β ≦ 63 are satisfied.
[0087]
If the search dot is included in the sprite surface 12G defined by the sprite table # 6 having the highest display priority and the end flag is 1, the image processing unit 10 determines that step S07 is true and determines that step S10 is true. Migrate to
[0088]
Next, the case where the position of the search dot is not included in the higher-priority sprite surface 12a as shown by the point c in FIG. 43 and the display priority is included in the lower sprite surface 12b than the sprite surface 12a will be described. To do.
[0089]
In this case, since the search dot does not satisfy the conditions 0 ≦ α ≦ 95 and 0 ≦ β ≦ 63 included in the sprite surface 12a, the determination result in step S07 becomes false, and the image processing unit 10 proceeds to step S08. Then, it is determined whether or not the table number of the table number register TNO is # 0 (step S08). If the table number of the table number register TNO is the table number # 6 of the sprite table whose end flag is 1, the determination process of step S08 is determined to be false, and the process proceeds to step S09.
[0090]
The image processing unit 10 decrements the table number of the table number register TNO by 1 (step S09), returns to step S07, and searches for the previous sprite table. That is, in this example, the sprite surface in which the search dots are set in the table in order toward the lower display priority order such as table number # 5, table number # 4, table number # 3... Table number # 0. It is determined whether it is included. When the sprite surface 12b of FIG. 43 is set in the sprite table # 5, when the table number of the table number register TNO is # 5, it is determined that the search dot is included in the sprite surface 12b, and the determination in step S07 is performed. The result is true, and the image processing unit 10 proceeds to step S10.
[0091]
Further, when the position of the search dot is in an area where no sprite surface is defined as shown by point d in FIG. 43, the determination result in step S07 is always false and the processing in steps S07 to S08 is performed. The table number of the table number register TNO becomes smaller as # 5, # 4, # 3..., The table number becomes # 0, and it is determined to be true in step S08, and the process proceeds to step S14. .
[0092]
Next, the sprite color data processing when it is determined that the search dot is included in the sprite surface defined by the sprite table will be described.
[0093]
Note that the sprite table with the highest display priority with the end flag of 1 is the table number # 6, and the sprite surface defined by the table number # 6 is the sprite surface 12G shown in FIG. Even if the description is based on the sprite surface 12a, the substantial processing algorithm does not change, so the description will be based on the sprite surface 12a.
[0094]
First, the image processing unit 10 determines whether or not the setting of the sprite surface 12a in the symbol erasure control setting area of the sprite table is symbol erasure (step S10). If the setting value in the symbol erasure control setting area is 0, it is a normal sprite setting, and if the setting value is 1, it is a symbol erasing sprite setting.
[0095]
If the setting value in the symbol erasure control setting area is the setting of the symbol erasing sprite, the process proceeds to step S14, and the search dot in the sprite color data storage area as shown in FIG. The transparent color is set and stored in the storage area corresponding to the search X coordinate, that is, the value of the search X coordinate XR register (step S14), and the process proceeds to step S15.
[0096]
Further, as described above, even when the position of the search dot is in an area where no sprite surface is defined, the process proceeds to step S14, and therefore corresponds to the value of the search X coordinate XR register in the sprite color data storage area. The transparent color is set and stored in the storage area.
[0097]
If the set value in the symbol erasure control setting area is the normal sprite setting, the process proceeds to step S11, and the color data of the search dot at the search coordinates (XR, YR) is determined by the character data in the sprite table # 6. Color data search processing is performed (steps S11 to S13).
[0098]
In the color data search process, first, the search dot of the search coordinates (XR, YR) is included in the tile number of each tile surface constituting the sprite surface 12a defined in the sprite table # 6, and the tile's Find how many dots are defined.
[0099]
As shown in FIG. 44, the sprite surface 12a is composed of tile numbers # 0 to # 5. As described above, if the display start coordinates (X1, Y1) of the sprite surface 12a are regarded as the coordinate base point (0, 0), the coordinates (XR, YR) of the search dots are (XR-X1, YR-Y1). And XR-X1 = α and YR-Y1 = β, the coordinates of the search dot are (α, β).
[0100]
The array combination size is set to horizontal direction h = 3 and vertical direction v = 2, and the size of one tile surface is 32 dots in the horizontal direction and 32 dots in the vertical direction.
In the horizontal direction, α / 32 = S1 (quotient)... M1 (residue)
For the vertical direction, β / 32 = S2 (quotient)... M2 (remainder)
Defined as
The tile number Ti is Ti = (S2 × h) + S1,
The dot number Do is Do = (M2 × 32) + M1,
Is required. That is, the coordinates (α, β) of the search dot correspond to the Do number dot of the Ti number tile.
[0101]
As an example, if the coordinates of the search dot (α, β) = (68,34),
In the horizontal direction, α / 32 = S1 (quotient)... M1 (remainder) = 2.
For the vertical direction, β / 32 = S2 (quotient)... M2 (remainder) = 1.
And
The tile number Ti is Ti = (S2 × h) + S1 = (1 × 3) + 2 = 5.
The dot number Do is Do = (M2 × 32) + M1 = (2 × 32) + 4 = 68.
Thus, the coordinates (68, 34) of the search dot are determined to correspond to the 68th dot of the # 5 tile.
[0102]
Next, the character data of the dot number Do in the tile number Ti is obtained from the address AD in the character ROM 6 of the first tile set in the character number setting area of the sprite table, the obtained tile number Ti, and the dot number Do. Is read from the character ROM 6.
[0103]
4 and 5, since the data for one tile is 256 bytes, the head address of the tile number Ti is AD + (Ti × 256) = AD + 1280, and the character data stored in one record Since the number is 4, the address AD1 where the character data of the dot number Do is stored is defined as Do / 4 = S3... M3.
AD1 = (AD + 1280) + S3, and 16-bit data stored in the address AD1 is read from the character ROM 6. Further, 4 bits from the 4 × M3 bit from the beginning of the read 16-bit data is the character data of the dot number Do in the tile number Ti.
[0104]
In the above example, since the dot number is 68, Do / 4 = 68/4 = 17... 0, and the top address (AD + 1280) + 17 = AD + 1297 of the fifth tile is the character data of the 68th dot of the # 5 tile. The stored address AD1 is obtained, and the 16-bit data stored in the address (AD + 1297) is read from the character ROM 6. In addition, since the character data of the 68th dot of the # 5 tile is 4 × M3 = 4 × 0 = 0, it corresponds to 4 bits from the 0th bit of the read 16-bit data. .
[0105]
When the image processing unit 10 reads the 4-bit character data (0 to 15) corresponding to the search dot as described above, it is designated by the palette number set in the palette select control setting area of the sprite table. The pallet table (A) is selected (see FIG. 18). Character data (0 to 15) is for reading out color data by designating one of 16 colors in the palette table. For example, if the value of the character data is 7, the number 7 in the palette table is used. Color data is read out. The format of the color data is as shown in FIG.
[0106]
When the image processing unit 10 reads the sprite color data designated by the character data from the selected palette table (step S12), the image processing unit 10 searches the sprite color data storage area as shown in FIG. 45 provided in the work area of the memory 9. The sprite color data is set and stored in the storage area corresponding to the search X coordinate of the dot, that is, the value of the search X coordinate XR register (step S13), and the process proceeds to step S15.
[0107]
As described above, when the image processing unit 10 determines the sprite color data of the search dot designated by the search X coordinate setting register XR and the search Y coordinate setting register YR, the process proceeds to step S15, and the search X coordinate setting is performed. The value of the register XR is incremented by 1 to specify the next search dot (step S15), and then it is determined whether or not the search for the dot for one line is completed (step S16). That is, it is determined whether or not the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14. If XR> 199, the image processing unit 10 returns to step S04 and performs a search for the next search dot.
[0108]
As described above, when it is determined that the position of the search dot is included in the sprite surface 12G defined by the sprite table # 6 having the highest display priority with the end flag being 1, the sprite color data processing is performed. It is clear that the sprite color data of the search dot is determined with reference to the sprite table # 6 and the sprite color data processing is not performed for the sprite tables # 5 to # 0 lower than the sprite table # 6. is there.
[0109]
If the position of the search dot is not included in the sprite surface 12G defined by the sprite table # 6 having the highest display priority with the end flag being 1, the sprite table # 5 having the display priority one lower is searched. Thus, if it is determined that the position of the search dot is included in the sprite surface 12 defined in the sprite table # 5, the sprite color data processing refers to the sprite of the search dot with reference to the sprite table # 5. It is obvious that the sprite color data processing is not performed for the sprite tables # 4 to # 0 lower than the sprite table # 5 as the color data is determined.
[0110]
In the sprite color data processing in the sprite table, when the set value in the symbol erasure control setting area is the symbol erasure sprite setting, a transparent color is set as the sprite color data. Further, even when the position of the search dot is in an area where no sprite surface is defined, a transparent color is set as the sprite color data.
[0111]
The processing described above is repeated, and the sprite color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined each time the value of the search X coordinate setting register XR is incremented by one. To go. When the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14, all the sprite color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined. As a result, the image processing unit 10 shifts to background processing.
[0112]
Next, background processing will be described.
[0113]
The background processing is processing for determining background color data for one line of the display screen 14. It is assumed that the entire display screen 14 is included in the background surface 11. FIG. 40 is a flowchart illustrating an outline of background processing executed by the image processing unit 10. When starting the background processing, the image processing unit 10 sets 0 in the search X coordinate setting register XR for searching each row of each dot arrangement on the display screen 14 in the horizontal direction (step S20), and proceeds to step S21. To do.
[0114]
Note that the value of the search Y coordinate setting register YR determines the background color data to be overlapped with the sprite color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR. And a common value.
[0115]
In step S21, the image processing unit 10 reads the background surface horizontal direction display start coordinate B1 and the background surface vertical direction display start coordinate B2 set in the common image control setting table of FIG. 21 (step S21). The process proceeds to step S22.
[0116]
In step S22, the image processing unit 10 shifts the base coordinates (0, 0) of the sprite virtual screen 15 that matches the base point 16 of the display screen 14 based on the read horizontal display start coordinates B1 and vertical display start coordinates B2. 0) The search dot coordinates (XR, YR) specified by the value of the search X coordinate setting register XR and the value of the search Y coordinate setting register YR viewed from 0) are the base coordinates for the background (0 , 0), the coordinates are obtained (step S22).
[0117]
If the search dot coordinates viewed from the background base coordinates (0, 0) are (BX, BY), the background plane horizontal display start coordinates B1 and the background plane set in the common image control setting table of FIG. Based on the vertical direction display start coordinate B2, the base point coordinates (0, 0) = (XR, YR) of the sprite virtual screen 15 are viewed from the base point coordinates (0, 0) for the background (B1, B2). Matches
Search dot X coordinate BX = B1 + XR,
Search dot Y coordinate BY = B2 + YR.
[0118]
After the processing in step S22, the image processing unit 10 reads the character data of the search dot designated by the coordinates (BX, BY) from the character ROM 6 (step S23).
[0119]
First, the number of dots in the number table (number BG character surface) on the background surface 11 shown in FIG. 8 corresponds to the number of dots in the search dot defined by the search dot coordinates (BX, BY).
[0120]
The dot configuration of the BG character surface is the same as the tile surface constituting the sprite surface, and is 32 dots in the horizontal direction and 32 dots in the vertical direction. As shown in FIG. 8, the background surface 11 has 16 horizontal surfaces in the vertical direction. By being composed of 8 BG character planes arranged in a matrix,
In the horizontal direction, BX / 32 = S4 (quotient)... M4 (remainder)
For the vertical direction, BY / 32 = S5 (quotient)... M5 (remainder)
Defined as
The table number TN is TN = (S5 × 16) + S4,
The dot number DN is DN = (M5 × 32) + M4,
Is required.
That is, the search dot of the search coordinate (BX, BY) corresponds to the DN number dot of the TN number table.
[0121]
As an example, if the coordinates of the search dot (BX, BY) = (68, 34),
In the horizontal direction, BX / 32 = S4 (quotient)... M4 (remainder) = 2.
For the vertical direction, BY / 32 = S5 (quotient)... M5 (remainder) = 1.
And
The table number TN is TN = (S5 × 16) + S4 = (1 × 16) + 2 = 18
The dot number DN is DN = (M5 × 32) + M4 = (2 × 32) + 4 = 68.
Thus, the coordinates (68, 34) of the search dot correspond to the 68th dot in the # 18 table.
[0122]
Next, the image processing unit 10 reads the head address AD in the character ROM 6 stored in the TN number table in the background table setting area. Referring to FIG. 9, since the number of character data stored in one record is two, the address AD2 storing the character data of the dot number DN is defined as DN / 2 = S6... M6.
AD2 = AD + S6, and the 16-bit data stored in the address AD2 is read from the character ROM 6. Further, 8 bits from the beginning of the 8 × M6 bit from the beginning of the read 16-bit data becomes the character data of the dot number DN in the table number TN.
[0123]
In the above example, since the dot number is 68, DN / 2 = 68/2 = 34... 0, and the address (AD + 34) obtained by adding 34 to the start address AD of the # 18 table is the dot number DN in the table number TN. The character data stored in the address (AD + 34) is read from the character ROM 6. Further, the character data of the 68th dot in the # 18 table is 8 × M6 = 8 × 0 = 0, and therefore, it is 8 bits from the 0th bit from the head of the read 16-bit data. .
[0124]
When the image processing unit 10 reads the 8-bit character data (0 to 255) corresponding to the search dot as described above (step S23), the image processing unit 10 selects the palette table of the palette table (B) (FIG. 20). reference). Character data (0 to 255) is for reading out color data by designating one of 256 colors in the palette table. For example, if the value of the character data is 16, the character data (0 to 255) is stored in the palette table (B). No. 16 color data is read out (step S24). The format of the color data is as shown in FIG.
[0125]
When the image processing unit 10 reads the sprite color data designated by the character data from the palette table (B), the image processing unit 10 searches for the search dots in the background color data storage area as shown in FIG. 46 provided in the work area of the memory 9. The background color data is set and stored in the storage area corresponding to the value of the search X coordinate, that is, the value of the search X coordinate XR register (step S25), and the process proceeds to step S26.
[0126]
As described above, when the image processing unit 10 determines the background color data of the search dot designated by the search X coordinate setting register XR and the search Y coordinate setting register YR, the process proceeds to step S26, and the search X coordinate is determined. The value of the setting register XR is incremented by 1 to designate the next search dot (step S26), and then it is determined whether or not the search for the dot for one line is completed (step S27). That is, it is determined whether or not the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14. If XR> 199, the image processing unit 10 returns to step S22 and searches for the next search dot.
[0127]
The processing described above is repeated, and the background color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined each time the value of the search X coordinate setting register XR is incremented by one. I will do it. When the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14, all the background color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined. As a result, the image processing unit 10 proceeds to output color data determination processing.
[0128]
Next, output color data determination processing will be described.
[0129]
The output color data determination process refers to the sprite color data for one line of the display screen 14 created by the sprite process and the background color data for one line of the display screen 14 created by the background process. This is processing for determining output color data representing an image that is finally displayed when the sprite surface 12 is superimposed on the ground surface 11. As described above, the display priority of the background surface 11 is set lower than that of the sprite surface 12.
[0130]
FIG. 41 is a flowchart illustrating an outline of output color data determination processing executed by the image processing unit 10. The image processing unit 10 that has started the output color data determination process first sets 0 to the search X coordinate setting register XR (step S30), and proceeds to step S31. That is, the output color data is determined in the order of the first row, the second row,.
[0131]
In step S31, the image processing unit 10 reads the sprite color data stored in the storage area corresponding to the value of the search X coordinate XR register in the sprite color data storage area (step S31). It is determined whether or not the color is transparent (step S32).
[0132]
If it is determined in step S32 that the sprite color data is a transparent color, the image processing unit 10 proceeds to step S33 and sets the value of the search X coordinate XR register in the background color data storage area. The background color data stored in the corresponding storage area is transferred to the storage area corresponding to the value of the search X coordinate XR register in the output color data storage area set in the work area of the memory 9 as shown in FIG. (Step S33), the process proceeds to Step S35.
[0133]
If it is determined in step S32 that the sprite color data is not transparent, that is, if the sprite color data is visible color data, the image processing unit 10 proceeds to step S34. The transferred sprite color data is transferred to the storage area corresponding to the value of the search X coordinate XR register in the output color data storage area (step S34), and the process proceeds to step S35.
[0134]
That is, when the sprite color data is visible color data, the sprite color data is output color data, and when the sprite color data is a transparent color, the background color data is output color data. As described above, as a result of the sprite process, when symbol deletion is set on the sprite surface 12, a transparent color is set. In this case, background color data becomes output color data. .
[0135]
In step S35, the image processing unit 10 increments the value of the search X coordinate setting register XR by one to specify the next search dot (step S35), and then outputs color data for one line of dots. It is determined whether or not the determination has been completed (step S36). That is, it is determined whether or not the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14. If XR> 199, the image processing unit 10 returns to step S31 and performs a search for the next search dot.
[0136]
The process described above is repeated, and the output color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined each time the value of the search X coordinate setting register XR is incremented by one. To go. When the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14, all output color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is determined. Thus, the image processing unit 10 shifts to color data output processing.
[0137]
Next, the color data output process will be described. The color data output process is a process for outputting the output color data for one line created in the output color data determination process to the D / A converter 8.
[0138]
FIG. 42 is a flowchart schematically showing the color data output process. When starting the color data output process, the image processing unit 10 first sets 0 to the search X coordinate setting register XR (step S40), and proceeds to step S41. That is, the color output data is sequentially output in the order of the first row, the second row,.
[0139]
In step S41, the image processing unit 10 sets the output color data in the output color data storage area specified by the search X coordinate setting register XR in the output buffer (step S41), and then proceeds to step S42.
[0140]
The image processing unit 10 that has moved to step S42 outputs the color data set in the output buffer to the D / A converter 8 in the figure in accordance with the timing of the horizontal synchronizing signal and the vertical synchronizing signal shown in FIG. 22 (step S42). . For example, if the value of the search X coordinate setting register XR is 0, 0 dot color data is output.
[0141]
When the output of the color data set in the output buffer is finished, the image processing unit 10 increases the value of the search X coordinate setting register XR by one and designates the next search dot (step S43), and then one line It is determined whether or not the output of the output color data for the minute dot has been completed (step S44). That is, it is determined whether or not the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14. If XR> 199, the image processing unit 10 returns to step S41 and outputs output color data for the next dot.
[0142]
The processing described above is repeated, the output color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is sequentially incremented by one in the search X coordinate setting register XR, and the horizontal synchronization signal In accordance with this timing, output color data from the output color data of the 0th column to the 199th column are output to the D / A converter 8 in order.
[0143]
When the value of the search X coordinate setting register XR exceeds the horizontal size 199 of the display screen 14, all the output color data for one line of the display screen 14 specified by the value of the search Y coordinate setting register YR is all. It is output (step S44).
[0144]
Next, the image processing unit 10 increments the value of the search Y coordinate setting register YR by one and designates the next line (step S45), and the output of the output color data for one surface of the display screen 14 is completed. Whether or not (step S46). That is, it is determined whether or not the value of the search Y coordinate setting register YR exceeds the vertical size 159 of the display screen 14. If YR> 159, the image processing unit 10 proceeds to sprite processing for the next row designated by the value of the search Y coordinate setting register YR.
[0145]
In the sprite processing shown in FIG. 38, since the value of the execution flag F1 remains 1, the image processing unit 10 proceeds to step S17 and sets only the value of the search X coordinate setting register XR to 0 (step S17), the process proceeds to step S04, and the sprite process for the next line designated by the value of the search Y coordinate setting register YR is started.
[0146]
The process described above is repeated each time the value of the search Y coordinate setting register YR is increased by one. That is, sprite color data for one line on the display screen 14 is created, then background color data for one line on the display screen 14 is created, and then the created sprite color data and background color data are referenced. Then, the output color data for one line of the display screen 14 is created, and the process of outputting the output color data for one line of the created display screen 14 is incremented by one for the value of the search Y coordinate setting register YR. Repeat every time.
[0147]
When the value of the search Y coordinate setting register YR exceeds the vertical size 159 of the display screen 14, the output of the output color data for one surface of the display screen 14 is completed, and the image processing unit 10 Then, the value of the execution flag F1 is cleared to 0 (step S47), and the sprite processing, background processing, output color data processing, and color data output processing for one surface on the display screen 14 are finished.
[0148]
In the above example, when creating output color data for one line, sprite color data for one line of the display screen 14 is created, and then background color data for one line of the display screen 14 is created, Next, referring to the created sprite color data and background color data, the output color data for one line of the display screen 14 was created in units of one line. Create one dot, then create one dot of background color data for the search dot, then refer to the sprite color data and the background color data for one dot and set the output color data of the search dot to 1 It is also possible to perform one dot unit so as to create dots, and to repeat the processing of one dot unit over one line. In this way, it is only necessary to provide one dot for the sprite color data storage area and the background color data storage area in the work area, and it is not necessary to secure one line for each of the storage areas. Can be used for
[0149]
Next, the video display of the liquid crystal display device displayed in the pachinko game according to the gaming state will be described. The pachinko game machine opens and closes a single winning and closing cycle of the grand prize opening on condition that the big winning opening is opened and a game ball passes through a specific area within the big winning opening when a big hit occurs. It is assumed that the opening / closing operation of the grand prize opening is repeated periodically up to 16 times after the end of the game. In the following description, for example, a video image displayed on the liquid crystal display unit 5 when the jackpot occurs and the period of the opening / closing operation of the big prize opening is the fifth time will be described as an example.
[0150]
As an example, the sprite surfaces 12A to 12G are set in the above-described sprite tables # 0 to # 6, and are set so as to be displayed at display coordinate positions as shown in FIG.
[0151]
48 to 51 are flowcharts showing the display control process at the fifth consecutive time during the jackpot that is a part of the control program executed by the sub CPU 2.
[0152]
First, the sub CPU 2 searches the status of the command data transferred to the RAM 4 and determines whether or not the pachinko gaming machine is currently in a big jackpot (step P01). If it is determined that the jackpot is not a big hit, the sub CPU 2 ends the process without starting the display control process at the fifth consecutive time.
[0153]
When it is determined that the pachinko gaming machine is currently in a big jackpot, the sub CPU 2 next determines whether or not the status round number is 5 (step P02). When it is determined that the number of status rounds is not 5, the sub CPU 2 ends the process without starting the display control process at the fifth consecutive time.
[0154]
If it is determined in the determination process of step P02 that the number of status rounds is 5, the sub CPU 2 proceeds to step P03 and determines whether or not the execution start flag F2 is the initial value 0 (step P03). ). Note that the value of the execution start flag F2 is assumed to be an initial value 0 when a display control process is newly started at the fifth consecutive time. The sub CPU 2 sets the execution start flag F2 to a value 1 that defines execution, stores the start of execution (step P04), sets an initial value 0 to the display state identification counter f1 (step P05), and displays for movement display. The initial value 0 is set to the execution flag f2 (step P06), and the process proceeds to step P07.
[0155]
The sub CPU 2 performs settings related to the initial screen displayed on the display screen 14 by the processing of Step P07 to Step P09.
[0156]
In Step P07, a background surface 11A representing the inside of the castle as shown in FIG. 23 is set in the background table.
[0157]
In step P08, the sprite surface 12A representing the number “5” as shown in FIG. 24 is set in the sprite table # 0. Note that the value 0 (continue) is set in the end flag of the sprite table # 0.
[0158]
In Step P09, the sprite surface 12B representing the round “R” as shown in FIG. 25 is set in the sprite table # 1. Note that the value 1 (end) is set in the end flag of the sprite table # 1.
[0159]
After the process of step P09, the sub CPU 2 proceeds to step P10, sets a predetermined value in the display counter (step P10), and ends the display control process of the current cycle.
[0160]
As a result of the execution start flag F2 being set to the value 1 that defines execution, if the determination processing of step P01 and step P02 is determined to be true in the subsequent display control processing, the execution start flag F2 of step P03 is determined. Therefore, the sub CPU 2 proceeds to Step P11.
[0161]
In step P11, the value of the display counter is subtracted, and in the subsequent step P12, it is determined whether or not the value of the display counter has reached zero. If it is determined that the value of the display counter is not 0, the sub CPU 2 ends the display control process for the current cycle. Hereinafter, the sub CPU 2 is formed by Step P01, Step P02, Step P03, Step P11, and Step P12 until the value of the display counter reaches 0 on the condition that the number of rounds is 5 and the jackpot. Repeat the waiting process loop.
[0162]
While the sub CPU 2 performs the standby processing loop, the image processing unit 10 performs the above-described sprite processing, background processing, output color data processing, and color data output processing. Since the end flag of the sprite table # 1 is 1, the sprite tables # 1 and # 0 are sprite processed, and the sprite surface 12A and the sprite surface 12B are combined with the background surface 11A on the display screen 14, An image showing the inside of the castle and 5R shown in FIG. 32 is displayed. In the following description, sprite processing, background processing, output color data processing, and color data output processing are referred to as image composition processing.
[0163]
When the value of the display counter reaches 0 while the sub CPU 2 repeats the standby processing loop, the sub CPU 2 proceeds to step P13 after the determination in step P12, and increases the value of the display state identification counter f1 by one (step P13) and the process proceeds to Step P14. The current value of the display state identification counter f1 is 1.
[0164]
The processing after step P14 is branched to each processing by the sub CPU 2 according to the value of the display state identification counter f1 by the discrimination processing of step P14 to step P17.
[0165]
In Step P14, it is determined whether or not the value of the display state identification counter f1 is 1. Since the current value of the display state identification counter f1 is 1, the sub CPU 2 proceeds to Step P18 and executes a footprint display subroutine (Step P18).
[0166]
FIG. 50 is a flowchart showing an outline of a footprint display subroutine. The sub CPU 2 sets 0 (continue) in the end flag of the sprite table # 1 (step P30), and sets a sprite surface 12C representing a footprint as shown in FIG. 26 in the sprite table # 2 (step P31). Note that the value 0 (continue) is set in the end flag of the sprite table # 2.
[0167]
Next, the sub CPU 2 sets a sprite surface 12D representing a footprint as shown in FIG. 26 in the sprite table # 3 (step P32). Note that the value 0 (continue) is set in the end flag of the sprite table # 3, and the value 1 (design deletion) is set in the symbol deletion control setting area.
[0168]
Next, the sub CPU 2 sets a sprite surface 12E representing a footprint as shown in FIG. 26 in the sprite table # 4 (step P33). Note that the value 0 (continue) is set in the end flag of the sprite table # 4.
[0169]
Next, the sub CPU 2 sets a sprite surface 12F representing a footprint as shown in FIG. 26 in the sprite table # 5 (step P34). Note that the value 1 (end) is set in the end flag of the sprite table # 5, and the value 1 (design deletion) is set in the symbol deletion control setting area. The sub CPU 2 returns to the main routine after the process of step P34.
[0170]
After executing the footprint display subroutine in step P18, the sub CPU 2 proceeds to step P10, sets a predetermined value in the display counter (step P10), and ends the display control process of the current cycle.
[0171]
After the next cycle, the sub CPU 2 repeatedly performs the standby processing loop. Note that while the sub CPU 2 is performing the standby processing loop, the image synthesis processing is performed by the image processing unit 10. Since the end flag of sprite table # 5 is 1, sprite tables # 5 to # 0 are sprite processed. Further, since the sprite tables # 3 and # 5 are set for symbol deletion, the background surface 11A is displayed in the display area of the sprite surface 12D and the sprite surface 12F. On the display screen 14, the sprite surface 12A, the sprite surface 12B, and the sprite surfaces 12C to 12F are combined with the background surface 11A. As shown in FIG. 33, two footprints are combined and displayed on the image showing the inside of the castle and 5R. It will be.
[0172]
When the value of the display counter reaches 0 while the sub CPU 2 repeats the standby processing loop, the sub CPU 2 proceeds to step P13 after the determination in step P12, and increases the value of the display state identification counter f1 by one (step P13) and the process proceeds to Step P14. The current value of the display state identification counter f1 is 2.
[0173]
After determining that Step P14 is false, the sub CPU 2 proceeds to Step P15. In Step P15, it is determined whether or not the value of the display state identification counter f1 is 2. Since the current value of the display state identification counter f1 is 2, the sub CPU 2 proceeds to step P19, sets 0 (continue) to the end flag of the sprite table # 5 (step P19), and stores it in the sprite table # 6. A sprite surface 12G representing a ninja as shown in FIG. 27 is set (step P20). Note that the value 1 (end) is set in the end flag of the sprite table # 6.
[0174]
After the process of Step P20, the process proceeds to Step P10, a predetermined value is set in the display counter (Step P10), and the display control process of the current cycle is finished.
[0175]
After the next cycle, the sub CPU 2 repeatedly performs the standby processing loop. Note that while the sub CPU 2 is performing the standby processing loop, the image synthesis processing is performed by the image processing unit 10. Since the end flag of the sprite table # 6 is 1, the sprite tables # 6 to # 0 are sprite processed. Further, since the sprite tables # 3 and # 5 are set for symbol deletion, the background surface 11A is displayed in the display area of the sprite surface 12D and the sprite surface 12F. On the display screen 14, the sprite surface 12A, the sprite surface 12B, the sprite surfaces 12C to 12F, and the sprite surface 12G are synthesized with the background surface 11A. As shown in FIG. Will be displayed in combination.
[0176]
When the value of the display counter reaches 0 while the sub CPU 2 repeats the standby processing loop, the sub CPU 2 proceeds to step P13 after the determination in step P12, and increases the value of the display state identification counter f1 by one (step P13) and the process proceeds to Step P14. The current value of the display state identification counter f1 is 3.
[0177]
After determining that Step P14 and Step P15 are false, the sub CPU 2 proceeds to Step P16. In Step P16, it is determined whether or not the value of the display state identification counter f1 is 3. Since the current value of the display state identification counter f1 is 3, the sub CPU 2 proceeds to step P21.
[0178]
The sub CPU 2 switches the setting in the symbol erasure control setting area of the sprite table # 3 and the sprite table # 5 to the value 0 (normal sprite), respectively (step P21), proceeds to step P10, and sets a predetermined value in the display counter. (Step P10), the display control process of the current cycle is finished.
[0179]
After the next cycle, the sub CPU 2 repeatedly performs the standby processing loop. Note that while the sub CPU 2 is performing the standby processing loop, the image synthesis processing is performed by the image processing unit 10. Since the end flag of the sprite table # 6 is 1, the sprite tables # 6 to # 0 are sprite processed. Since the sprite tables # 3 and # 5 are set as normal sprites, the display screen 14 is composed of the sprite surface 12A, the sprite surface 12B, the sprite surfaces 12C to 12F, and the sprite surface 12G on the background surface 11A. Then, as shown in FIG. 35, the ninja and the four footprints are synthesized and displayed in the image showing the inside of the castle and 5R.
[0180]
When the value of the display counter reaches 0 while the sub CPU 2 repeats the standby processing loop, the sub CPU 2 proceeds to step P13 after the determination in step P12, and increases the value of the display state identification counter f1 by one (step P13) and the process proceeds to Step P14. The current value of the display state identification counter f1 is 4.
[0181]
After determining that Step P14, Step P15, and Step P16 are false, the sub CPU 2 proceeds to Step P17. In step P17, it is determined whether or not the value of the display state identification counter f1 is within a range of 4 ≦ f1 ≦ n (where n> 5). Since the current value of the display state identification counter f1 is 4, the sub CPU 2 shifts to the ninja movement display process of step P22.
[0182]
FIG. 51 is a flowchart showing an outline of the ninja movement display process. When the sub CPU 2 starts the ninja movement display process, it first determines whether or not the movement display execution flag f2 is 0 (step P40). When the ninja movement display process is newly started, the movement display execution flag f2 is set to 0 by the process of step P06. The sub CPU 2 determines that step P40 is true, sets 1 to the movement display execution flag f2 and stores the execution in progress (step P41), sets the erasure switching flag to 0 (step P42), and proceeds to step P43. To do.
[0183]
The sub CPU 2 that has proceeded to Step P43 sets the X coordinate values of the display start positions of the sprite tables # 2 to # 5 defining the four footprints separately and the sprite table # 6 defining the ninja by ΔX (X−ΔX) is set as the X coordinate position of each display start position of the sprite tables # 2 to # 6, and the process proceeds to step P44. Thereby, the display positions of the ninja and the four footprints move to the left side on the display screen 14.
[0184]
The sub CPU 2 that has proceeded to Step P44 determines whether or not the erasure switching flag is 0 (Step P44). If the ninja movement display process is newly started, since the erasure switching flag is set to 0, the sub CPU 2 determines that it is true and proceeds to step P45.
[0185]
In step P45, the setting in the symbol erasure control setting area of sprite table # 3 and sprite table # 5 is switched to value 1 (design erasure) (step P45), and then in step P46, the value of the erasure switching flag is changed from 0. It is switched to 1.
[0186]
The sub CPU 2 returns to the main routine after the process of step P46, proceeds to step P10, sets a predetermined value in the display counter (step P10), and ends the display control process of the current cycle.
[0187]
After the next cycle, the sub CPU 2 repeatedly performs the standby processing loop. Note that while the sub CPU 2 is performing the standby processing loop, the image synthesis processing is performed by the image processing unit 10. Since the end flag of the sprite table # 6 is 1, the sprite tables # 6 to # 0 are sprite processed.
[0188]
Further, since the sprite tables # 3 and # 5 are set for symbol erasing, the background surface 11A is displayed in the display area of the sprite surface 12D and the sprite surface 12F, and the display screen 14 displays the background surface. The sprite surface 12A, the sprite surface 12B, the sprite surfaces 12C to 12F, and the sprite surface 12G are combined with 11A, and as shown in FIG. 34, the ninja and two footprints are combined and displayed on the image showing the inside of the castle and 5R. . However, the ninja and the two footprints are shifted to the left side of the display screen 14 from the display position shown in FIG.
[0189]
When the value of the display counter reaches 0 while the sub CPU 2 repeats the standby processing loop, the sub CPU 2 proceeds to step P13 after the determination in step P12, and increases the value of the display state identification counter f1 by one (step P13) and the process proceeds to Step P14. The current value of the display state identification counter f1 is 5.
[0190]
After determining that Step P14, Step P15, and Step P16 are false, the sub CPU 2 proceeds to Step P17, and since the current value of the display state identification counter f1 is 5, the sub CPU 2 proceeds to the ninja movement display process in Step P22 again.
[0191]
In the ninja movement display process to be executed this time, as a result of the movement display execution flag f2 being set to 1, the sub CPU 2 determines that step P40 is false and then proceeds to step P43, and the sprite tables # 2 to # 6. (X−ΔX) is set as the X coordinate position of each display start position, and the process proceeds to Step P44.
[0192]
In step P44, since the erasure switching flag is set to 1, the sub CPU 2 determines that it is false and proceeds to step P47.
[0193]
In step P47, the settings in the symbol erasure control setting area of sprite table # 3 and sprite table # 5 are respectively switched to the value 0 (normal sprite) (step P47). Then, in step P48, the value of the erasure switching flag is changed from 1. Switched to zero.
[0194]
After the process of step P48, the sub CPU 2 returns to the main routine, proceeds to step P10, sets a predetermined value in the display counter (step P10), and ends the display control process of the current cycle.
[0195]
After the next cycle, the sub CPU 2 repeatedly performs the standby processing loop. Note that while the sub CPU 2 is performing the standby processing loop, the image synthesis processing is performed by the image processing unit 10. Since the end flag of the sprite table # 6 is 1, the sprite tables # 6 to # 0 are sprite processed.
[0196]
Since the sprite tables # 3 and # 5 are set as normal sprites, the display screen 14 is composed of the sprite surface 12A, the sprite surface 12B, the sprite surfaces 12C to 12F, and the sprite surface 12G on the background surface 11A. Then, as shown in FIG. 35, the ninja and the four footprints are synthesized and displayed in the image showing the inside of the castle and 5R. However, the ninja and the four footprints are shifted to the left side of the display screen 14 from the display positions of the last two ninjas and the footprints.
[0197]
As is apparent from the flowchart shown in FIG. 49, the switching display between the two footprints and the four footprints is performed until the value of the display state identification counter f1 reaches n. By updating the value of the display state identification counter f1 when the value of the display counter reaches 0, the ninja and the footprint are on the left side of the display screen 14 until the value of the display state identification counter f1 exceeds n. In addition, two footprints and four footprints are alternately displayed every time the display position changes, and it is visually recognized as if a ninja is running.
[0198]
When the value of the display state identification counter f1 exceeds n, the determination result in step P17 becomes false, and the sub CPU 2 returns to step P05 and performs the setting for the initial screen in FIG. 32 again.
[0199]
Note that the display control process at the fifth consecutive time is continued on the condition that the jackpot is in progress and the number of rounds is five. When a change occurs in the gaming state on the pachinko gaming machine side, if the content of the sent status is a big hit and the number of rounds is not 5, the determination in step P01 or step P02 is false and the execution flag F2 is cleared. (Step P23), the display control process at the fifth consecutive time is completed.
[0200]
As is clear from the above description, according to the liquid crystal display device 1, the symbol screen data representing the state in which the symbol is erased is displayed on the sprite surface 12 superimposed on the background surface 11. Without being provided, the symbols set on the sprite surface 12 can be erased on the display screen, and the symbols on the background surface can be displayed in the erased portion.
[0201]
In addition, a sprite surface table for setting the display content of the sprite surface 12 is provided, and setting to the symbol erasure control setting area for setting whether to execute the display of the moving image or the deletion display of the moving image set in the sprite surface table. By simply switching the state, it is possible to easily control the display and deletion of the symbols set on the sprite surface on the display screen, and the background surface symbols can be displayed at the sprite surface deletion portion. it can.
[0202]
This eliminates the need for the character ROM 6 to have a large capacity, simplifies display processing for screen display, and shortens display processing time consumed for screen display.
[0203]
The common image control setting table used in the embodiment of the invention described above includes a superimpose control bit for specifying whether or not to perform superimpose processing, and a raster for specifying whether or not to perform raster scroll processing. Scroll control bit, Mosaic processing control bit for setting multi-tone mosaic processing for sprite surface, Fade-out processing control for multi-tone fade-out color adjustment for each color output value of red, green and blue Bits are provided, and the sprite table controls the horizontal and vertical reduction ratio control bits for setting the horizontal and vertical reduction ratios, the horizontal inversion display (flip processing) of the sprites, and the vertical flip processing. The horizontal and vertical flip control bits may be provided.
[0204]
In the embodiment of the present invention described above, the image control table is composed of the common image control setting table, the sprite table, the palette table, and the background table. It is good also as a structure which enables a simple image processing.
[0205]
In the embodiment of the present invention described above, the image displayed on the liquid crystal display screen of the pachinko machine includes the sprite color data for the display screen created by the sprite processing and the background for the display screen created by the background processing. Since the final determination is made with reference to the color data, the effect of determining the output color when a plurality of images are superimposed and displayed can be realized extremely easily.
[0206]
In addition, a special flag (end flag) is provided to continue and stop sprite surface processing that displays images on the liquid crystal display screen of pachinko machines, so that all sprite tables prepared in advance are processed. Therefore, there is an effect that the image data can be processed extremely smoothly and quickly.
[0207]
Since the image displayed on the liquid crystal display screen is switched by the display state identification counter, there is an effect that various display switching can be performed programmatically according to the progress state of the pachinko game.
[0208]
Since the movement display execution flag is set to move (change) the character displayed on the liquid crystal display screen of the pachinko machine, the stationary character corresponding to the pachinko game mode is simply programmed. By changing the execution flag for moving display on / off above, an effect of switching to the moving state is produced.
[0209]
Since it has a configuration with an erasure switching flag to switch between the display state of the image displayed on the liquid crystal display screen of the pachinko machine and the erasure state, the program according to the progress state of the pachinko game, By selecting ON / OFF of the erasure switching flag, there is an effect that it is possible to easily switch between the state of displaying an image on the liquid crystal display screen of the pachinko machine and the state of erasing the image from the screen.
[0210]
【The invention's effect】
According to the liquid crystal display device of the pachinko machine of the present invention, the symbol set on the sprite surface superimposed and displayed on the background surface, without specially providing symbol screen data representing a state where the symbol is erased, The symbols set on the sprite surface can be erased on the display screen, and the symbols on the background surface can be displayed in the erased portion, thereby eliminating the need for a large capacity character ROM.
[0211]
In addition, each sprite surface is configured by a combination of a plurality of tile surfaces arranged in a matrix in one direction in each surface and in a direction perpendicular thereto, so that the size of the sprite surface can be arbitrarily set in units of tile surfaces. Can do.
[0212]
In addition, by providing a symbol display erasing unit that erases the display of the sprite surface and displays only the background surface, the size of the erased portion can be changed in units of tile surfaces.
[0213]
Furthermore, a sprite surface table for setting the display content of the sprite surface is provided, and display editing means for setting either the display execution of the moving image or the deletion display of the moving image set in the sprite surface table is provided in the sprite surface table. Therefore, it is possible to easily switch between display and deletion of the symbols set on the sprite surface on the display screen simply by switching the setting state of the display editing means, and at the back of the sprite surface, The design of the ground plane can be displayed, the display processing for screen display can be simplified, and the display processing time consumed for screen display can be shortened.
