Abstract
In an image read-out method, image signals are obtained by scanning a material-to-be-scanned, which carries an image recording thereon and which is conveyed in a sub-scanning direction, by a light beam deflected by a rotating polygon mirror in a main scanning direction approximately normal to the sub-scanning direction, and photoelectrically detecting light, which carries the image and which is obtained from a portion scanned by the light beam, by a photodetector. The image signals each obtained in each of main scanning steps in a number obtained by a single turn of the rotating polygon mirror or turns thereof in a number equal to integral multiples of one are addition-processed to obtain an image signal over a single main scanning line.
