## Abstract

A cost increase is controlled. A solid imaging device according to an embodiment includes: an imaging section (101) that obtains first image data including four or more colors; and a converting section (104) that reduces the number of colors of the first image data obtained by the imaging section and generates second image data having a smaller number of colors than the first image data.
