Abstract
An imaging control unit 4 specifies a scan region including an effective pixel region and a blanking region based on the magnification for electronic zooming, and converts an input optical signal into an electrical signal by scanning the scan region. The imaging control unit 4 reads the electrical signal stored therein and delivers it to an image sensor unit 1 as picture data. An RW control unit 6 stores the picture data in a register 5 based on the magnification for electronic zooming, and then reads the picture data at a predetermined frame rate. A resolution converter 7 performs an interpolation processing on the picture data based on the magnification for electronic zooming.
