Abstract:
1. An imaging apparatus comprising: an image capturing unit that alternately outputs one unit image's worth of a primary video signal obtained by capturing a subject image for a first exposure time and one unit image's worth of a secondary video signal obtained by capturing the subject image for a second exposure time, the one unit image's worth of the primary video signal and the one unit image's worth of the secondary video signal being output at a frame cycle that is equal or longer than sum of the first exposure time and the second exposure time; a flash detection unit that determines whether or not the influence of an external flash is present in at least one of the primary video signal and the secondary video signal; and a flash correction unit that corrects the influence of the external flash by (1) outputting, in the case where the flash detection unit has determined that the influence of an external flash is present, a flash-corrected video signal obtained by adding, to the primary video signal, the secondary video signal, obtained over the second exposure time, that is temporally before or after the first exposure time over which the primary video signal was obtained, and (2) outputting, in the case where the flash detection unit has determined that the influence of an external flash is not present, the primary video signal.
