The attribute register 55 has a CG
Memory register 55a, priority register 55
b, register 55c for continuous mode, register 55d for RGB blending ratio, register 55e for translucent blending ratio, register 55f for display start position, fade setting register 55g,
Etc. The contents of these registers are set by the video control CPU 51 performing detailed processing for displaying an image on the color image processing and display device 10 according to an image control signal sent from the main CPU 50.

The CG memory register 55a is
This is a register for writing the reading start position of the character image stored in the memory 54 in the horizontal direction H and the vertical direction V, and writing the size of the character image read from the CG memory 54 in the horizontal direction H and the vertical direction V.

The continuous mode register 55c is used to repeatedly and continuously display an image to be displayed on the color image processing and display device 10 to form a pattern or the like having a predetermined size. A predetermined unit image is stored in the CG memory 5
4, the number of the unit images to be repeatedly displayed is written in the horizontal direction H and the vertical direction V, and the display interval is written in the horizontal direction H and the vertical direction V.

The RGB blending ratio register 55d is for writing the R, G, B color data blending ratio in order to change the color of the color image displayed on the color image processing and display device 10. That is, the mixing ratio set by the RGB mixing ratio register 55d is the color processing filter 6
0, where the image read from the color palette 59 is subjected to color processing.

The translucent compounding ratio register 55e is
When the two character images are read from the G memory 54 and are displayed in a superimposed manner, the rate at which the colors of the two character images are mixed is written. The priority register 55b is for writing which character image is to be displayed with priority when the two character images are displayed in a superimposed manner. The priority-designated character image is displayed on the front side. , The character image not specified as priority is displayed on the back side.

With such a configuration, the priority register 55b and the translucent compounding ratio register 55e
Is performed in the translucent filter 61 based on the attribute written in the. In the present embodiment, a color in which the color of the character image displayed on the upper side and the color of the character image displayed on the lower side are mixed is generated, and the overlappingly displayed portion is represented by the generated mixed color. Thus, the character image displayed on the upper side is made translucent.

When the translucency processing is instructed, the display data of the area where the translucency processing of the lower image already written is read out from the frame memory 62, and the upper image supplied from the color processing filter 60 is read out. The display data is R,
Averaging is performed for each of the G and B colors, and the result is rewritten in the frame memory 62. When the translucency processing is not instructed, the display data of the upper image supplied from the color processing filter 60 is overwritten.

The display start position register 55f is
This is a register for writing the display start position of the character image to be read from the CG memory 54 and displayed on the color image processing display device 10. This display start position is written in the horizontal direction H and the vertical direction V.

The fade setting register 55g is a register for writing information about a color image to be displayed on the color image processing display device 10, such as what mixing ratio and at what timing a mixed color image is generated. In the present embodiment, a mode flag, a start flag, a stop flag, a restart flag, color information to start at fade-in, color information to converge at fade-out,
Various information such as a translucent blending ratio, a processing frame interval, and a processing number is written.

Hereinafter, each of these pieces of information will be described in detail. The mode flag is information for determining either fade-in or fade-out. The start flag is normally “L”, and when this flag rises, the fade process is automatically started according to the contents of the mode flag. The stop flag is normally “L”, and when this flag rises, the fade process is temporarily suspended and waits until the restart flag rises. The restart flag is
Normally, it is "L", and when this flag rises, the interrupted fade process is restarted.

By using such a stop flag and a restart flag as a set, the fade process is interrupted while the image gradually becomes thinner or gradually becomes darker, and the image at that time is interrupted. Is displayed for a predetermined time, and then the fade processing is further continued, and the display expression power of one character image can be further improved.

The start color information is used in the fade-in mode. Immediately after the start of the fade processing, the fade starts from the set color, and the next image can gradually emerge. On the other hand, the converging color information is used in the fade-out mode. Immediately after the start of the fade processing, the image that has been displayed until then can gradually adapt to this set color. The translucent blending ratio is information for setting a blending ratio between the start color or the converging color and the color of the image read from the frame memory 62, and is set in a range of 0 to 1.

The frame interval to be processed is information for setting how many frames of an image are subjected to the color mixing process (semi-transparent process). Perform translucent processing at each interval. The number to be processed is information for setting how many times the translucent processing is performed, and the number of times of processing is specified in advance. When the count value has counted "0", the process is automatically terminated, and the start flag is returned to "L". Depending on the setting of the frame interval and the number of frames to be processed, the processing can be completed before the fade is completely completed.

Next, the CG memory address generation circuit 56
Is the above C output from the CG memory register 55a.
Based on the information about the G memory 54, the CG memory 54
This is for generating an address indicating a position at which a character image is to be read from the. That is, the horizontal direction H _x is the read start position to read the image data in the window 54a of the specified size from the vertical direction V _y.

The HV counter 57 sets a count value for repeatedly reading a unit image from the CG memory 54 based on the data relating to the continuous display output from the continuous mode register 55c, and generates the CG memory address. It is derived to the circuit 56. Further, for the image display side, the count value is incremented in the horizontal direction H and the vertical direction V, and is derived to the frame memory address generation circuit 58.

The CG memory address generating circuit 56
A read address of the CG memory 54 is generated based on a count signal given from the V counter 57. Then, a predetermined unit image is repeatedly read from the CG memory 54 according to the address.

The repetitive reading of the unit image is actually performed separately in each of the horizontal direction H and the vertical direction V. That is, for a certain image, after the image data is read for the horizontal H line, the read operation for the horizontal H line is repeated. When the reading operation for a horizontal line is completed by repeating such a reading operation a predetermined number of times, the same reading operation is performed for the next horizontal line H, thereby repeating the reading operation a predetermined number of times in both the horizontal direction H and the vertical direction V. Reading is performed.

As described above, the image data read from the CG memory 54 is subjected to predetermined processing in the color palette 59, the color processing filter 60, and the translucent filter 61, and then written to the frame memory 62. .

The frame memory 62 is a memory for storing one screen of image data to be displayed on the color image processing and display device 10, and has two fields of an odd line field memory and an even line field memory. Has memory. Then, when the image data written in one field memory is being read, the image data is written in the other field memory, so that the color image processing display device 10 continuously displays the image. I have.

The fade filter 63 performs fade-in or fade-out processing based on the contents set in the fade setting register 55g. FIG. 4 is a block diagram showing a more detailed configuration of the fade filter 63, and FIG. 5 is a timing chart showing the operation of the fade filter 63 shown in FIG.

In FIG. 4, the translucent processing unit 31 includes an image read from the frame memory 62 and a mixed color (a start color at the time of fade-in or a convergent color at the time of fade-out) stored in a part of the fade setting register 55g. ) To perform translucent processing for each screen, and output the resulting mixed color image to the color image processing and display device 10. However, if the value of the coefficient (mixing ratio) A of the translucent processing is “0”, the image of the frame memory 62 is output as it is, and if the value of the coefficient A is “1”, the color to be mixed is output as it is.

The coefficient A is automatically generated by a configuration other than the translucent processing section 31 in the fade filter 63. That is, when the start flag supplied to the second latch 33 is “L”, no processing is performed as shown in FIG. 5, and the flip-flop 37 continues to output “0” as the value of the coefficient A. . When the start flag becomes “H”, the first counter 34 and the flip-flop 37 start operating and the vertical synchronizing signal Vs rising at one frame period.
Start counting the number of SYNC by the first counter 34.

The first counter 34 is a counter for counting the processing frame interval set in the fade setting register 55g. Here, it is assumed that the frame interval is set to “3”, for example. In this case, the first counter 34 outputs a signal of “H” every time three vertical synchronization signals Vsync are counted. First counter 3
If the stop flag supplied to the first latch 32 is "L" when the "H" signal is output from the "4", the translucent blending ratio α set in the fade setting register 55g is AND gated. The signal is supplied to an adder / subtractor 36 via 35.

The adder / subtractor 36 adds the output from the AND gate 35 and the output from the flip-flop 37.
Since “0” is set in the flip-flop 37 in the first stage, the adder / subtractor 36 sets the translucent blending ratio α
Is output to the flip-flop 37 as it is. The flip-flop 37 latches the output of the adder / subtractor 36 in synchronization with the next rise of the vertical synchronization signal Vsync.
As a result, the flip-flop 37 outputs “α” as the value of the coefficient A in the next stage.

By repeating such processing, the flip-flop 37 sets “0”, “α”, “2” as the coefficient A used in the translucent processing unit 31 as shown in FIG.
α ”,“ 3α ”,...
A mixed image having a changed mixing ratio every three frames is sequentially output from the translucent processing unit 31 to the color image processing display device 10, and a fade-in or a fade-out is realized.

If the stop flag becomes "H" in the course of such a fade process, a signal of "0" is outputted from the AND gate 35 instead of the translucent blending ratio α. As a result, the value of the coefficient A output from the flip-flop 37 does not change, and the fade process is interrupted. Thereafter, when the restart flag becomes “H”, the translucent mixture ratio α starts to be output again from the AND gate 35, and the fade process is restarted.

The second counter 38 counts the "H" signal output from the first counter 34, and counts the number of times of the fade process set in the fade setting register 55g. . When the count is counted up to the set number, the start flag supplied to the second latch 33 is returned to “L”, and the fade processing ends.

As described above, according to the color image processing and displaying apparatus of the pachinko machine according to the present embodiment, the screen is gradually changed to the specific color by performing the specific color and the translucent processing on the screen in the fade filter 63. Or the screen gradually rises from a specific color. For example, by setting a specific color to white, fade-in or fade-out can be automatically performed without adjusting the luminance as shown in FIG.

In the translucent filter 61, the translucent processing is performed for each character using a fixed blending ratio. However, similar to the fade filter 63, the translucent processing is performed by changing the blending ratio at a predetermined frame interval. By doing
As shown in FIG. 2B, only a specific character image can be faded in or out.

FIG. 6 shows an example in which the color image processing and displaying apparatus 10 of the present embodiment is mounted on a pachinko machine 70. Here, the pachinko machine 70 is taken as an example, but the present invention can be applied to amusement machines whose memory capacity is limited other than the pachinko machine. In the above embodiment, the frame memory 62 is used, but a line memory may be used.

[0055]

As described above, the present invention relates to a color image processing and display apparatus for a pachinko machine having a function of performing predetermined image processing on image data read from a CG memory and displaying the image data. Since the process of generating a color obtained by mixing the color of the image stored in the means and the specified specific color and setting it as a display color is sequentially performed while changing the mixing ratio stepwise, the pachinko machine is used. When displaying an image on the image processing display device attached to the, it is possible to gradually converge the image stored in the storage means to a specific color, or to gradually rise from a specific color, For example, by making the specific color white, it is possible to realize fade-in and fade-out without adjusting the luminance. As a result, switching between various character images can be automatically and smoothly performed, and the expressiveness of image switching and image display can be improved.
