摘要： In a solid state imaging device to be included in an imaging device such as a digital camera, a ramp run-up AD conversion circuit for AD converting a pixel signal is provided corresponding to one or a plurality of pixel columns. A column counter provided in each ramp run-up AD conversion circuit holds an upper bit, and a clock signal is supplied to one or plural latches for holding a lower bit. Thus, fast and accurate AD conversion can be realized while suppressing increase of clock frequency.

摘要： 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.

摘要： An image pickup control unit specifies a scan area of a frame based on a scaling factor for electronic zooming. An image sensor converts incoming light signals into electric signals by performing reset scanning on each line of the specified scan area of the frame, and accumulates each of the electric signals, and reads the electric signals accumulated thereby by performing read scanning to output them as image data. In response to an instruction for changing a horizontal scanning period and a vertical scanning period of an Nth frame and later frames in a series of frames from the image pickup control unit, the image sensor performs reset scanning and read scanning on the Nth frame based on the changed horizontal scanning and vertical scanning periods even when a reset scanning period of the Nth frame partially overlaps a read scanning period of an immediately preceding (N-1)th frame.
