Image processing apparatus.

摘要

A processing time is reduced without using expensive hardware. A head reads images of originals which are contained in an i-th original photo film Fi all at one time as it moves in a subscanning direction and as an original drum rotates in a main scanning direction. At this stage, a switch connects the head to a first band memory and a switch connects a second band memory to an image processing circuit. During the reading of the images, image signals are stored in memory sectors of the first band memory original by original while image signals regarding an (i-1)-th original photo film (F(i-1)) are serially read, processed and stored in a magnetic disk original by original. When the head read images of an original photo film (F(i+1)) all at one time, the switches are switched each other so that writing in the second band memory and reading from the first band memory are performed simultaneously.
