DETAILED DESCRIPTION Therefore, it is an object of the present invention to provide a still video camera for simultaneously 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.
According to an aspect of the present invention, a 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 by analyzing a mode control signal generated according to mode selections; a multi-screen controller for generating an A/D and D/A conversion sampling clocks, a multi-screen recording/reproducing control signal, and first and second switching control signals according to the recording/reproducing commands of the microprocessor; a A/D converter for converting modulated analog signals into digital signals according to the A/D conversion sampling clock; an analog switch for supplying the luminance signal, the first and second chrominance signals to the A/D converter according to the first switching control signal; multi-screen memories for recording multi-screen image signals in response to the multi-screen recording/reproducing control signal generated from the multi-screen controller; D/A converters for generating luminance signal, and a first and second chrominance signals by converting the signals generated from the recording media into analog signals according to the D/A conversion sampling clock of the multi-screen controller; a video switch for selectively generating the image signals, and the luminance signal, and the first and second chrominance signals from the D/A converters according to the second switching control signal; and an encoder for encoding the signal generated from the video switch and a synchronizing signal so as to generate composite image signals
