ABSTRACT:
The invention is disclosed to provide a still video camera for reproducing a plurality of image source signals recorded in a plurality of recording tracks on a plurality of sub-screens, or reproducing an image source signal recorded in one track on a plurality of sub-screens, by using a multi-screen memory. The still video camera having a modulator, a recording/reproducing amplifier, a demodulator, a camera controller, and reproducer controller, includes a microprocessor for generating recording/reproducing commands, a multi-screen controller for generating A/D and D/A sampling clocks, a multi-screen recording/reproducing control signal, first and second switching control signals, an A/D converter for converting the modulated analog signals into digital signals, an analog switch for supplying the luminance signal, the first and second chrominance signals to the A/D converter, multi-screen memories for recording multi-screen image source signals in response to the control signal from the multi-screen controller, a plurality of D/A converters for generating the luminance signal, and the first and second chrominance signals into analog signals, a video switch for switching the above luminance and chrominance signals, and an encoder for encoding the signals passed through the video switch and a sysnchronizing signal so as to generate composite image signals.
