In the structure of the stereoscopic image receiving apparatus according to the present invention, the conventional image receiving apparatus has an A / D converter 1, a memory block 2, a D / A converter 3, and a frequency whose frequency is higher than that of a synchronous signal of an ordinary video signal. Frequency double circuit (A) consisting of a synchronization signal generator (4) generating twice as fast synchronization signal (119.88 Hz), vertical frequency detection circuit (5), wired / wireless eyeglass driving circuit (6), and infrared ray for driving wireless glasses An eyeglass driving circuit (b) consisting of an LED 7 and a wired eyeglass connection jack 8 is added. In the multi-image playback apparatus of the present invention configured as described above, an odd and even screen is displayed through an A / D converter 41 which converts an existing video signal obtained through an image detector of an image circuit from analog to digital. The combined page frames are converted into digital image data and then stored in the memory block 42. The memory block 42 of the frequency double circuit holds a memory for two pages of images, which are alternately stored. In the D / A converter 43 for converting a digital signal into an analog signal, the odd number (odd1) and the even value (even1) are stored in the first page of the memory block, and the odd number (odd2) and even (even2) are stored in the second page. The odd signal and even1 are alternately modulated twice in the synchronization signal received from the synchronization signal generator 44 whose frequency is twice as fast as the synchronization signal of the normal video signal, and sent to the video amplifier of the video circuit. .

FIG. 8 shows the image waveform of each component generated in such an operation process on the time axis. Referring to this, odd1 and even1 of the basic video signal 1 are stored, and again, odd2 and even2 are stored. In the frequency doubled video signal 3, the doubled video signal is generated as odd11 and even11 and odd12 and even12, respectively. If this operation process is repeated, the frequency doubled video signal 3 of the present invention produces odd21 and even21, and odd22 and even22 while odd3 and even3 are stored in the basic video signal 1. It happens repeatedly. The spectacle driving circuit (b) obtains the signal obtained from the synchronizing signal generator 44 of FIG. 7 or from the synchronizing deflection circuit, and generates the LCD spectacle driving signal from the vertical frequency detecting circuit 45 to the wired / wireless driving circuit. In this case, the wired glasses are configured to be directly connected to the eyeglass connection jack 48, and in the case of wireless glasses, the glasses driving circuit (b) is configured to connect the infrared LED 47 for driving the wireless glasses via the wireless driving circuit 46. .
