Abstract
Abstract Apparatus and method for recording color picture information on a record medium, in which luminance information is recorded in one frame portion on the record medium and coded color information is recorded in a separate frame portion. Such luminance information may be in pictorial form and recorded either optically or electronically by a recording beam. The color information takes the form of a record including a first, carrier signal component modulated in amplitude and phase according to the color saturation and hue in the original scene and a superimposed reference carrier signal component bearing a fixed frequency relation to the color carrier signal, so that the recorded cycles of the respective carriers tend to be aligned in a common direction in the color frame. Recording may be carried out by scanning laser, electron or optical beam. as desired. The record medium may be reproduced by directing an image of a respective one of the frame portions to separate television cameras for producing a luminance signal and signals at the color and reference carrier frequencies.
