DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication game terminal device used in equipment capable of playing games such as Go and Othello using a narrowband transmission path such as a telephone line.

2. Description of the Related Art Electronic devices are known that play games such as Go and Othello by displaying or inputting figures using a television receiver or the like.

However, in the past, in most cases, a television receiver was used to repeatedly learn and record Go scores, or a CATV line was used to unilaterally provide game data from a center to the user. However, it was impossible to select and connect arbitrary opponents using communication lines and play games such as Go between remote locations. The present invention was developed in view of the above circumstances, and allows a user to select a desired communication partner from among a large number of unspecified communication partners, and to send and receive information between them via a communication line such as a telephone line.

A checkerboard figure displayed on the display surface of the display device 108 is shown in FIG.

The Go board is formed by unit patterns corresponding to each lattice point of the Go board. Each unit pattern is arranged in 19 rows of 1 i.

In the following explanation, the display position of each unit pattern will be expressed in rectangular coordinates based on the upper left corner of the Go board, and the position of the grid point (unit pattern) in the mth row and nth column will be (m, n).

The figure shows the relationship between the display position of the unit pattern on the display device 108 and the image signal, where Pm,n represents the origin position of the unit pattern in the m-th row and n-th column of the Go board.

Next, the operation of the communication Go terminal device of the present invention will be explained using FIGS. 1 to 4.

To play Go using the communication Go terminal device shown in Figure 1,
Two of these devices are connected via a telephone line network or the like.

This connection is made by dialing the other party's number using the telephone set 112 with a public address system in the same way as a normal telephone call. At this point, the Go board shape shown in FIG. 2 is displayed on the display device 108 connected to both communication Go terminal devices 114. The display of this Go board shape is the original oscillator 1 for TV signals.
This is done by counting down the pulses from 07 in the checkerboard figure generator 104. First, the method of generating this Go board figure will be described. In this case, the display device 108 is of a raster scanning type with 525 scanning lines, and to simplify the explanation, a sequential display method of 1/3 of one frame is used. do.

Now, the television signal original oscillator 107 is an oscillator that oscillates at a dot frequency or an integral multiple thereof for displaying figures in dots on the raster scanning display device 108. For example, the pixel clock oscillates at a frequency of about 5.7 MHz. , the oscillation output at the frequency of the dot is supplied to the checkerboard figure generator 104 through the signal line 120.

In FIG. 3, a 1/12 countdown circuit 301 counts down this frequency and outputs a signal "1" for each pixel, that is, for each time interval of the vertical lines of the Go board. This output is applied to vertical and horizontal line generation circuit 304 to create the clock position for vertical line generation. In addition, the 1'12 countdown circuit 301
The clock counted down by 1/12 is applied to a 1'30 countdown circuit 302, which outputs an output pulse every three unit patterns, that is, every horizontal scanning line. In other words,
In this case, as shown in FIG. 4, it is assumed that three mountain stroke pattern times are allocated to one horizontal scanning time. The output pulse from the 1/30 countdown circuit 302 is applied to the 1/12 countdown circuit 303, which outputs an output pulse every 12 horizontal scan lines, that is, every horizontal line of the Go board.

This output is applied to the vertical and horizontal line generation circuit 304 and indicates the clock position of horizontal line generation. The vertical and horizontal line generation circuit 304 is a logic circuit, and one of the inputs indicates a black line.
When it takes "1", it outputs "1".Furthermore, the output of the 1'30 countdown circuit 302 is applied to the 1/525 countdown circuit 305, which outputs an output every 525 horizontal scanning lines, that is, every frame.This output is added to the frame detection circuit 306 to detect the end of the frame. Also, the output from this circuit 306 performs IJ setting of other counters. On the other hand, the 1/12 countdown circuit 301
The output of P. is applied to the vertical frame setting circuit 307, and by counting the number of unit patterns from the horizontal scanning start point, this circuit determines the unit pattern position P. of one horizontal scanning line. , n (n=1
Detects the time points P, 9, and n) between times P, 9, and 19), and instructs the gate circuit 310 that the period is within the horizontal frame of the Go board.

In addition, the output of the 1/12 countdown circuit 303 is applied to the horizontal frame setting circuit 308, and by telling this circuit the number of unit patterns in the vertical direction from the starting point of the frame, unit pattern positions Pn, , (n= 1 to 19) and Pn, , 9 (n=1 to 19) are detected, and the gate circuit 3101 instructs that the period between them is within the vertical frame of the Go board. The gate circuit 310 is a two-input AND circuit that receives outputs from the vertical frame setting circuit 307 and the horizontal frame setting circuit 308, and both output "1".
In this case, the pattern switching section 105 is instructed to create a signal of a Go board shape. Counter circuits 311 and 312 are control circuits for erasing the outer black line portion within the Go board frame.

That is, the counter circuit 311 detects the left end of the Go board in the vertical frame setting circuit 307, and then counts the pixel clock of the signal line 120. A signal for erasing the horizontal black line 21 in FIG. 2 is output to the gate circuit 309.
Similarly, an instruction to erase the horizontal black line 22 at the right end of the Go board is also given. The count circuit 312 is the horizontal frame setting circuit 3
When the upper end of the Go board is detected at step 08, the number of scanning lines coming from the 1/30 countdown circuit 302 is started counting, and the instruction is given to erase the vertical black line 23 by 6 lines, that is, half of the vertical width of the unit pattern (1st pixel). is output to the gate circuit 309. Similarly, the lower vertical black line 24 is also erased. The gate circuit 309 is a three-input logic circuit, and the vertical and horizontal line generation circuit 30
The pattern switching unit 1 of FIG.
05 to generate a black line signal. The pattern switching unit 105 is a combinational circuit, and a gate circuit 310 indicates that there is no instruction to display a stone from the stone pattern generation unit 103 (described later), and there is no instruction from a gate circuit 309 indicating a black line on the Go board, indicating that the stone is within the Go board frame. When there is an instruction from the gate circuit 309, a gray signal indicating a Go board is displayed, and when there is no instruction from the stone pattern generation unit 103 and there is an instruction from the gate circuit 309 indicating a black line on the Go board, the gate indicates that the gate is within the Go board frame. circuit 3
When there is an instruction of 10, the television signal configuration unit 106 is instructed to output a black signal indicating a black line.

Note that when the gate circuit 310 instructs that it is outside the Go board frame, it instructs the television signal configuration unit 106 to create a background color black signal. The television signal configuration unit 106 adds a synchronization signal and the like based on these instructions, creates a television signal, and displays it on the display device 108. As a result, a Go board shape is displayed. Here, the player selects mode instruction section 1.
02 to instruct, for example, to take a black stone, the control section 100 encodes this and notifies it to the other party terminal through the transmission control section 111 and the transmission line 115.

Next, an explanation will be given of the operation when a player hits a stone onto the Go board displayed on the display device 108.

When a player wants to hit a stone, he or she uses the light ben 109 to indicate the position on the display device 108. Position detection unit 110
detects the raster position indicated by the light ben 109 on the raster scanning display device 108 at the signal timing of the signal line 120, and notifies the control unit 100 of the raster position. Control unit 10
A stone placement memory unit 101 is connected to the river, and this memory unit stores information about the stones placed at each of the 19×19 lattice points of the Go board at that time. Therefore, the grid point position indicated by the light ben 109 is looked at, and if no stone is placed there, a code indicating a black stone is written. next,
A method of displaying the stone information written in the memory unit 101 as a pattern on the display device 108 will be explained.

The stone information written in the memory 01 is sequentially read out in accordance with the generation of the television signal, and sent to the stone pattern generation section 103 through the control section 100. FIG. 5 shows the structure of the stone pattern generating section 103. 501 is a decoder circuit, 50
2 is a read-only memory (ROM), and 503 is a parallel-to-serial conversion circuit.

Figure 6 is a diagram showing the stone pattern as dots, and this 12×
A 12-dot pattern is stored in the special memory 502. The operation of the stone pattern generating section 103 will be explained using FIGS. 5 and 6.

The symbols of the stones corresponding to each lattice point sequentially read out from the memory 101 in accordance with the output of the television signal source oscillator 107 are as follows.
The signal is input to the decoder circuit 501 through the signal line 123.
Next, in accordance with the clock from the television signal source oscillator 107, the dot pattern in the ROM 502 is read out for each line required at that time and supplied to the parallel-to-serial conversion circuit 503, where it is converted into a serial signal. After, pattern switching section 105
is input to create a stone pattern television signal. The signals for creating the Go board figure described above are simultaneously input to this pattern switching unit 105 through signal lines 121 and 122, but priority is given to the stone pattern signal input through signal line 124. If there is a stone pattern signal, the checkerboard figure signal is ignored and the stone pattern signal is output. As a result, the stone figures placed on the Go board are displayed in place of the Go board figures without being displayed twice. At this time, the pattern switching unit 105 is controlled to output a black level when placing a black stone, and output a white level when placing a white stone. This control is possible by having the pattern switching section 105 decode the code given to the stone signal read out from the memory 01. By doing so, the discussion-only memory shown in FIG. 5 can use the same pattern for both white stones and black stones. The stones struck by the opponent can also be displayed using the same operations as above.

That is, when the control section 100 receives information about the stone hit by the opponent through the transmission control section 111, it interprets its position on the Go board, adds black or white information, and writes it into the memory 101. Reading from the memory 01 and displaying the stone pattern are performed by the method described above. As described above, according to the present invention, it is possible to select an arbitrary opponent in a remote location using a communication line and play a game such as Go while staying with the opponent.

In addition, the pattern generation circuit controls the detection of the position information of the driving stone by a light ben position detection device, etc., and the display of the driving stone at an arbitrary position on the display screen, so Go can be played between remote points via a communication line. It becomes possible to easily configure a communication Go terminal device for playing games such as the following.
