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 .
