Abstract:
1. An imaging device comprising: an image sensor unit for converting an input optical signal into an electrical signal, for storing the electrical signal, for reading the electrical signal stored, and for outputting the electrical signal read as picture data; a magnification specification unit for setting a magnification for electronic zooming; a parameter operation unit for calculating imaging parameters associated with the electronic zooming based on the magnification for electronic zooming specified by the magnification specification unit; an imaging control unit for specifying a scan region, including an effective pixel region and a blanking region, of an image which is to be scanned by said image sensor unit, based on the imaging parameters calculated by said parameter operation unit, and for controlling scanning timing at which said image sensor unit scans the scan region; a register for temporarily holding a part of the picture data output from said image sensor unit; a read write (RW) control unit for writing in said register at least one line of the picture data delivered from said image sensor unit based on the imaging parameters calculated by said parameter operation unit, and for reading the at least one line of the picture data at a fixed frame rate independent of the magnification; and a resolution converter for interpolation processing of the picture data read from said register based on the imaging parameters calculated by said parameter operation unit, converting the picture data into picture data having a size of one frame, and delivering the one frame as a video signal.
