In an information compression unit 311, the incidence angle directivity of pixel outputs of at least two pixel output units from among a plurality of pixel output units is modulated in accordance withthe angle of incidence of subject light that is incident without passing through either of an imaging lens and a pinhole in an imaging unit 121 (221), the at least two pixel output units receiving the subject light, and the pixel outputs of the at least two pixel output units are set so as to have different incidence angle directivity. The information compression unit 311 performs a compression process to reduce the data volume of pixel output information generated by the imaging unit 121 (221). The word length of the pixel output information is shortened by, for example, calculation of a difference between set reference value information and the pixel output information, linear computation of a set computation parameter and the pixel output information, etc., reducing the data volume ofthe pixel output information generated in accordance with the subject light that is incident without passing through either of the imaging lens and the pinhole.
