The image pickup device comprises: an image pickup unit 1 in which a plurality of unit cells for generating reset and read voltages are arranged; a noise eliminating unit 6 for generating, with respect to each unit cell, a differential voltage corresponding to a difference between the reset and read voltages; and output units 5 and 7 for outputting the read and differential voltages, respectively, to a signal processing apparatus. The signal processing apparatus comprises: a judging unit 8 for judging whether each of the read voltages is within a predetermined range; and a system output unit 9 for outputting, for unit cells whose voltages are judged as being within the predetermined range, corresponding differential voltages as luminance information of the unit cells; for unit cells whose voltages are judged as not being within the predetermined range, a predetermined voltage indicating high luminance as luminance information of the unit cells.
