This imaging device (100) includes a plurality of unit pixel cells (121). A unit pixel cell included in the plurality of unit pixel cells acquires first imaging data in a first exposure period in one frame and acquires second imaging data in a second exposure period different from the first exposure period in the one frame, and the sensitivity per unit time of the unit pixel cell differs in the first and second exposure periods. The imaging device (100) outputs multiple exposure image data including at least the first and second imaging data.
