An imaging apparatus, comprising: a signal processing unit reads pixel signals from a plurality of pixel circuits during a predetermined time, and stores at least first image data corresponding to a first frame which corresponds to a first exposure time, second image data corresponding to a second frame which corresponds to a second exposure time that is different from the first exposure time, and third image data corresponding to a third frame which corresponds to a third exposure time that is different from the second exposure time, a computing unit generates a first image using the image data corresponding to the first frame and third frame, and generates a second image using the image data corresponding to the second frame, wherein the exposure for the second frame is performed between the exposure for the first frame and the exposure for the third frame.
