Abstract:
1. A solid-state imaging device comprising: a pixel unit in which pixels are arranged in a matrix shape; an electronic shutter scanning control unit that controls accumulation time of the pixel unit to be different with respect to each line in a frame; a flicker detecting unit that detects, based on a magnitude relation of a signal amount in each of lines formed in the pixel unit with respect to an image signal of one frame picked up by the pixel unit, presence or absence of a flicker; a flicker-level estimating unit that estimates, based on the presence or absence of the flicker detected by the flicker detecting unit, a flicker level in each of the lines of a next frame; and a flicker correcting unit that corrects, based on the flicker level estimated by the flicker-level estimating unit, for each of the lines, a flicker that occurs in a signal of an image picked up by the pixel unit, wherein the flicker detecting unit includes a flicker-signal acquiring unit that acquires a flicker signal with respect to an image signal whose accumulation time is controlled such that a flicker occurs in only one of an odd number line or an even number line, an un-flicker signal acquiring unit that acquires an un-flickered signal with respect to an image signal where accumulation time is controlled such that a flicker does not occur in only the other of the odd number line and the even number line, and a difference-signal generating unit that generates a difference signal between the flicker signal and the un-flickered signal after correcting a level difference due to a difference between accumulation times.
