A compound-eye imaging device is a compound-eye imaging device having a plurality of facet optical systems, an imaging element, and a signal processing unit. The plurality of facet optical systems of the compound-eye imaging device are disposed to face a subject in a two dimensional shape. Also, the imaging element of the compound-eye imaging device includes, in units of facets, a plurality of pixels which receive light concentrated by facet optical systems and generate image signals. Also, the signal processing unit of the compound-eye imaging device generates an image corresponding to the subject based on image signals generated by the imaging element of the compound-eye imaging device.
