The imaging apparatus include a solid-state imaging device which has a plurality of pixels and outputs a pixel signal corresponding to a formed image of a subject as an image data; an image-capturing processing unit which outputs a pre-processed image data that is obtained by performing pre-processing on a part of the image data input from the solid-state imaging device, and an un-processed image data except the part of the image data from the image data input from the solid-state imaging device; and a storage unit which stores the pre-processed image data and the un-processed image data.
