Abstract

The imaging apparatus includes: an imaging device configured to convert light into an electric signal and output the electric signal; an exposure control section configured to variably control an exposure period of the imaging device using an electronic shutter; and a flicker detection section configured to Flicker is detected based on a change in an output signal from the imaging device when the speed of the electronic shutter changes from a relatively high speed to a relatively low speed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Priority Patent Application JP2013-112695 filed on May 29, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to an imaging device having an electronic shutter function, a method of detecting flicker in such an imaging device, and an information processing unit applicable to such an imaging device. Background technique [0004] In an imaging device including an imaging device such as a CMOS (Complementary Metal-Oxide Semiconductor), a global shutter type and a rolling shutter type are known as types of electronic shutters. The electronic shutter of the global shutter type simultaneously performs electronic shutter operations in all pixels. Therefore, when an electronic shutter of the global shutter type is used, the timing of exposure is the same in all pixels. The rolling shutter type electron...
