Abstract
Abstract A system for analyzing and reproducing the color information of an original picture is disclosed. A transmitting device is provided with a plurality of frame memories each of which stores a color image signal corresponding to a particular color component of the original. The time axis of the color image signals is changed by controlling the store speeds and the read out speeds of the memories. The color signals are read out and transmitted in a frame-sequential manner. At the time of transmission of each frame, a start signal is added to each color signal for use in the receiver of the system. At the receiver, a storage device is provided. The latter includes a plurality of memories each for storing a different one of the transmitted color signals. The storage device is responsive to the start signals in the color signals and storage in the memories is carried out in response to these start signals. A monitor is also provided at the receiver and the color image signals in the memories are read out in a dot sequential manner for display on the monitor. The start signal may be a combination of signals associated with the maximum and minimum values of the color image signals.
