Abstract
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.
