ABSTRACT:
An arrangement for photoelectric scanning of color pictures evaluates scanning light beams in three or more color filters according to different sensitivity curves. Photoelectric receivers then derive evaluation signals which are coded in three color value signals. In such arrangements, construction which is as simple, as economical and as space saving as possible is desired. Linear charge transfer device image sensors are respectively aligned to one another and the same line of the color picture. The image points of at least one image sensor are divided into two or more groups to which color filters of different, group-specific evaluation curves and group-specific charge coupled devices are assigned at whose outputs separate evaluation signals occur. The area of application is in color film scanners in which a color television screen serves as the reproduction device.
