ABSTRACT:
An image information detector of a photographic printer comprises a two-dimensional image sensor at a line sensor disposed near a film negative placed on a film carrier to receive and sense a light from a light source which has been transmitted through or refelected from the film negative. The entire image of the film negative is divided into a plurality of equally aligned picture elements by the two-dimensional image sensor or line sensor, which is driven by a driving circuit. Signals regarding image information of the divided picture elements in analog form are processed by a circuit provided with a signal processing unit and a signal memory.
