Abstract

An imaging device, an imaging method and a nonvolatile recording medium are provided. The imaging device includes an imaging unit having a pixel group two-dimensionally arranged vertically and horizontally, and 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.

Description

technical field [0001] The present invention relates to an imaging device and an imaging method using a rolling shutter method. Background technique [0002] In recent years, digital cameras and video cameras employing a CMOS (Complementary Metal Oxide Semiconductor) type imaging device (hereinafter referred to as a CMOS image sensor) have generally spread. The CMOS image sensor is a structure in which a signal of each pixel is output by X-scan (vertical scan) and Y-scan (horizontal scan) from pixel groups arranged two-dimensionally in the vertical and horizontal directions. [0003] As a method of driving a CMOS image sensor, for example, a rolling shutter method described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-288904 ) described below is relatively common. The rolling shutter method is a method of sequentially scanning pixel groups arranged two-dimensionally in the vertical direction and the horizontal direction for each line in one frame per...
