S P E C I F I C A T I O N TO ALL WHOM IT MAY CONCERN: BE IT KNOWN that I, HEINER HERBST, a citizen of Germany residing at Am See 2, 8013 Haar, Germany, have invented certain new and useful improvements in "AN ARRANGEMENT FOR COLOR PICTURE SCANNING" and I do hereby declare that the following is a full, clear and concise description of the same, reference being had to the accompanying sheets of drawing and to the numerals of reference marked thereon which form a part of this specification. ABSTRACT OF THE DISCLOSURE An arrangement for photoelectric scanning of color pictures in which scanning light beams are evaluated in three or more color filters according to different sensitivity curves. Photoelectric receivers then drive evaluation signals which are coded into three color value signals. In such arrangements, it is desired to obtain constructions which are as simple, economic and space-saving as possible, as well as providing a great sensitivity to light. According to the invention, a charge transfer device image sensor has two image point rows lying adjacent one another and aligned in two lines of the color picture. The image points of the image sensor are combined into groups to which individual color filters and read-out channels are respectively assigned. In the read-out operation, the image information of one line are intermediately stored for the duration of one line. The field of application of the invention, in particular, is related to color film - i - scanners in which a color television screen serves as the reproduction device. - ii -
