An imaging device comprising an imaging element for focusing incident light to a light receiving element by the shutter opening to generate image data; a flash for emitting a flash toward an imaging direction of the imaging unit; a controller for controlling the imaging element so as to continuously open the shutter a plurality of times and controlling the flash so as to emit a flash at a second and following opening timings among the plurality of opening timings; and an image processor for generating new image data based on the image data generated by the imaging element by the imaging at the opening timing when the flash does not emit a flash and the image data generated by the imaging element by the imaging at the opening timing when the flash emits a flash.
