Abstract

Video receiving device with automatic intensity control, equipped with an image configuration system and image conversion apparatus with an input window, in which received images can be configured. It is adapted for the transformation of said images into electrical signals delivered at the output connection, where the bandwidth of the image produced at the output (6) of the image conversion device (3) corresponds to the light intensity region of the image which is transformed into a control signal for a means of checking (8,17) as an additional image-active component, (5, 15) synchronized with the scanning of image lines, and may affect the image signal in such a way so that the sensitivity of said point during image scanning decreases in wide bandwidth and increases in narrow bandwidth.
