Abstract:
1. An imaging device comprising: an imaging unit having a pixel group two-dimensionally arranged vertically and horizontally, and being configured to read pixel signals associated with generation of a frame image in units of lines by a rolling shutter system; and a drive unit configured to periodically switch, when a plurality of frame images are consecutively read from the imaging unit with a predetermined frame period in video recording, positions of a plurality of lines each of which is made a read object in each of the frame images in units of frames; wherein the drive unit performs switching such that positions of a plurality of lines, each of which is made a read object in each of two consecutive frame images, do not overlap each other to thereby make pixels of each of the lines output pixel signals with a period longer than the predetermined frame period; wherein the drive unit divides a plurality of lines each of which is made a read object of pixel signals associated with generation of one frame image into a number of groups, and makes pixels of each of the lines output pixel signals with a period corresponding to the number of groups; and wherein the imaging device further comprises a drive control unit configured to control the number of groups in accordance with an exposure time to be secured for a pixel group of each of the groups.
