ABSTRACT:
An information processing method and apparatus, which is adapted to use, for example, in the recording of color image information, calls for sampling a set of basic colors (e.g., green, red, and blue) at rates which are proportioned according to the resolving power of the human visual system respective of color, and arranging the resulting samples to produce a sequential video signal. In one implementation, green, red, and blue color image information is sampled at respective rates decreasing progressively from green to red to blue in producing a sequential signal which is recorded, and on playback a luminance signal for, say, a television display is derived from the sequential signal based only on the relatively high frequency (preferably both green and red but not blue) sample information. Moreover, to improve image registration with such customized sampling, delays are selectively interposed in the individual color signals in accordance with their respective sampling frequencies.
