Abstract:
1. An imaging apparatus comprising: a solid-state imaging device including a plurality of pixels that are formed and arranged as a two-dimensional array in a surface of a semiconductor substrate, wherein the plurality of pixels include a first pixel group having pixels that are arranged cyclically, and a second pixel group being different from the first pixel group and having pixels that are arranged cyclically; an imaging device driving unit that exposes the first pixel group during a first exposure period, exposes the second pixel group during a second exposure period that is a part of the first exposure period, and reads from the solid-state imaging device first image data captured by the first pixel group and second image data captured by the second pixel group separately; and a first shooting mode and a second shooting mode are provided, in the first shooting mode, the signal processing unit performs the image processing for the first and second image data separately to generate two pieces of subject image data, and in the second shooting mode, the signal processing unit combines the second image data with the first image data to generate one piece of subject image data, a flashlight emitting unit that is operated in the first shooting mode so as to emit flashlight during a period in which the first exposure period does not overlap with the second exposure period, and is operated in the second shooting mode so as to emit flashlight during a period in which the first exposure period overlaps with the second exposure period wherein when the flashlight is emitted, the signal processing unit corrects the second image data with a gain that is equal to or larger than a temporal ratio of the second exposure period to the first exposure period.
