An imaging device is provided which includes a solid-state imaging device that includes a plurality of pixels arranged in a form of a two-dimensional (2D) matrix, and outputs pixel signals corresponding to subject light incident on the plurality of pixels, and a plurality of image-acquiring units that acquire the pixel signals output from the solid-state imaging device, and output image data corresponding to the acquired pixel signals, wherein each of the plurality of image-acquiring units acquires pixel signals of one of divisional imaging regions obtained by dividing an imaging region in which all pixels arranged in the solid-state imaging device image the subject light by the number of image-acquiring units, and outputs image data corresponding to the acquired pixel signal of the divisional imaging region as divisional image data.
