Abstract
Vertical scanning speed and the accumulation time of photoelectric conversion elements arranged in a CCD are set in accordance with a resolution and a magnification set on a control panel. The accumulation time is set in a timing control section and the CCD is driven. The vertical scanning speed is set in a scan motor or is sent to an ADF control section for controlling a move of an original or an optical system, whereby the original is vertically scanned in response to the setup resolution and magnification for sampling the original image. As the accumulation time is changed, CCD output changes. Thus, to correct it, a gain and offset values as the accumulation time is changed are set in gain control sections, an odd/even correction section, and an offset correction section.
