ABSTRACT:
A picture image photographing apparatus is comprised of a lens system for imaging data on an original paper, a plurality of line sensors for inputting optical data imaged by the lens system and each comprised of a plurality of imaging elements for converting the optical signals on the line sensors into electrical signals, a plurality of output portions for outputting data signals which are converted from the electrical signals and have a predetermined voltage, and a signal processing portion for outputting a mean value as a final information with respect to a same portion of a same line on the paper, which is obtained from a plurality of the data signals supplied from the output portions. By the above components, it is possible to perform a high-speed processing for the read-out image and to extremely improve a signal to noise (SN) ratio due to optical shot noise.
