13. An imaging apparatus comprising:
-
a flash band detecting circuit that detects a start line and an end line of a flash band, which is a level difference for each line generated within a frame in accordance with flash light, based on a difference in exposure periods of a video signal for each line that is output for each frame by a pixel included in an imaging device employing a rolling shutter system; and a flash band correcting circuit that outputs an output frame that is corrected to a video in which there is no flash band generated within the frame.
