Abstract:
An image signal recording apparatus for recording, on a recording medium, color image signals corresponding to an image in which one picture is composed of M horizontal scanning lines (M is a multiple of N N is an integer, N>1), comprising:a) color image signal output means for storing the color image signals for one picture and concurrently outputting N kinds of luminance component signals and N kinds of chrominance signals corresponding respectively to N number of horizontal scanning lines which are adjacent to each other on the picture;b) frequency-band limiting means for inputting the N kinds of luminance component signals and the N kinds of chrominance signals concurrently output from said color image signal output means, for limiting and outputting the frequency bands of the inputted N kinds of luminance component signals, respectively, and for limiting and outputting the frequency-bands of the inputted N kinds of chrominance signals to frequency bands lower than the limited frequency bands of the N kinds of luminance component signals, respectively;c) record color image signal forming means for forming and concurrently outputting N kinds of record color image signals by multiplexing the frequency-band limited N kinds of luminance component signals and N kinds of chrominance signals outputted from said frequency-band limiting means; andd) recording means for concurrently recording the N kinds of record color image signals concurrently outputted from said record color image signal forming means onto separate areas on the recording medium.
