US Patent 7336303 Imaging device

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