An imaging device includes: a solid-state imaging element that includes a plurality of pixels arranged in rows and columns and configured to be read out nondestructively; and an image processor that performs image processing on a current image using an analysis result of a suitable image. The suitable image is obtained from the solid-state imaging element when an amount of signal charge accumulated in the plurality of pixels is greater than or equal to a first threshold that is predetermined, and the current image is obtained from the solid-state imaging element after a first exposure corresponding to conditions of image capturing.
