PROBLEM TO BE SOLVED: To improve overexposure or underexposure for a moving body region when a dynamic range is enlarged by performing image composition.SOLUTION: An imaging device comprises: an imaging part picking up a plurality of picked-up images with different exposures; an exposure controller controlling the exposure of the imaging part; a division part dividing each picked-up image into a plurality of blocks; and a decision part calculating a difference in signals of blocks corresponding to each other, for the plurality of picked-up images, and deciding a reference exposure region and an additional exposure region other than the reference exposure region on the basis of the difference. The imaging part picks up a first image at such an exposure value that weights the reference exposure region calculated by the exposure controller, and picks up a second image at such an exposure value that weights the additional exposure region calculated by the exposure controller. |
