Abstract: An imaging device includes an imaging unit including a plurality of pixels, respectively including photoelectric converters and charge accumulation nodes that accumulate signal charge. The imaging unit outputs image data based on signals corresponding to the signal charge accumulated in the charge accumulators. The imaging device includes an image processing unit that processes the image data output by the imaging unit. The imaging unit sequentially outputs a plurality of pieces of image data in one frame period by performing readout nondestructively. The image processing unit generates difference image data by determining a difference between two pieces of image data, selects output image data from initial image data and the difference image data, and combines the output image data and normal readout image data included in the plurality of pieces of image data, to generate combination-result image data.

Abstract: An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in a first frame. During the first period, pixel signal readout is performed on a first row in the pixel array PA. During the second period, pixel signal readout is performed on a second row in the pixel array PA. Each of the first period and the second period is a high-sensitivity exposure period. The third period is a low-sensitivity exposure period.
