Abstract:
An image signal recording and reproducing apparatus for recording an image signal in a recording medium having a plurality of recording tracks, the image signal corresponding to successive images screen by screen, comprising:a supplier for continuously supplying image data corresponding to the image signal, the image data individually representing a plurality of pixels each responsible for a specific color component;a processor for generating luminance data for each pixel, based on the image data,outputting in parallel a pair of separated luminance data obtained by halving the luminance data generated,generating two types of color difference data each corresponding to four pixels, based on the image data, andoutputting a compound color difference data obtained by alternately combining the two types of color difference data generated, by a predetermined unit;a compressing encoder for generating a pair of compressed luminance data and a compressed color difference data by giving a compressing operation to the pair of separated luminance data and the compound color difference data according to a predetermined algorithm;a modulator for generating a pair of luminance modulated signals and a color difference modulated signal by giving an analog modulating operation to the pair of compressed luminance data and the compressed color difference data; anda recorder for writing the pair of luminance modulated signals and the color difference modulated signal onto first to third parallel recording tracks of the recording medium.
