Device for scanning an image in successive lines, utilizing the electrical charge transfer, incorporating a line memory and a television camera incorporating such a device

摘要

A device for the electric scanning of luminous images. It includes a matrix of N lines and M columns of photosensitive points. A system incorporating a line memory of M points receives in parallel the electric charges supplied by the M points of the same line parasitic charge are removed by diodes. The system insures the injection of the same predetermined quantity of charges between each of the photosensitive points and the output of the device. An output shift register receives in parallel the charges supplied by the line memory and supplies in series a picture scanning electric signal. This device is particularly intended for use in a television camera.
