Abstract
An image processing apparatus for a phototelegraphic apparatus for transmitting a film image has a frame for holding a film in which an image is optically recorded, a line sensor consisting of an array of CCDs for reading the film image, a main scanning direction frame signal elimination circuit for eliminating signal components corresponding to the frame from maximum and minimum densities detected by a peak hold circuit among main scanning image signals, and a microcomputer for detecting signal components corresponding to the frame from subscanning image signals. Noise components in image signals obtained by the line sensor due to the presence of the frame or soiling or scratching of the film are eliminated with a simple circuit configuration.
