An imaging element of the present technology includes a first pixel block having a plurality of pixels including color filters of a same first color and a second pixel block having a plurality of pixels including color filters of a second color different from the first pixel block, the number of pixels of the second pixel block being different from the number of pixels of the first pixel block. The first pixel block and the second pixel block have a configuration in which a charge-voltage conversion unit and succeeding pixel constituent elements are among a plurality of pixels. The imaging element further includes a signal amount adjustment unit that adjusts an output signal amount output from each pixel of the first pixel block and the second pixel block. The signal amount adjusting unit adjusts the output signal amount so that the output signal amount concerning the first color and the output signal amount concerning the second color match.
