Abstract:
1. An imaging apparatus of a rolling shutter system that starts exposing an imaging element including a light receiving area with a plurality of lines while shifting exposure start timing line by line and that sequentially reads out information on the lines from lines in which a predetermined exposure time has passed, the imaging apparatus comprising: a read control device that reads out the information of the lines by controlling read-out lines so that the exposure start timing of all lines of the imaging element is different and the exposure start timing of adjacent lines is significantly shifted on a periodic basis; an imaging acquisition device that acquires an image of one frame by sorting the information of the lines sequentially read out by the read control device in order of line positions; and an exposure unevenness detection device that detects presence of exposure unevenness included in the acquired image of one frame and caused by flash emission of another person.
