ABSTRACT:
When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.
