Conventionally, when generating an image in which hand-shake is suppressed, by combining a plurality of images, an image quality may be degraded by performing a combination process even in the illuminance condition when no hand-shake occurs and the linear characteristic of luminance information may be deteriorated when combining a plurality of images, some which are inappropriately exposed. In order to solve these problems, it is possible to provide an imaging device capable of combining a first image of a size smaller than a target image obtained by pixel addition average and pixel addition with a second image having an amplified gain to obtain an appropriate exposure and a plenty of noise, so as to generate the target image and capable of varying the synthesis ratio of the first image and the second image according to the temperature condition and the like so as to obtain an image in which no hand-shake or blur is contained under any illuminance condition and noise is suppressed.
