1. An imaging device, comprising:
a plurality of pixel sets arranged two-dimensionally in a plan view,
wherein each pixel set of the plurality of pixel sets includes four photoelectric conversion regions,
wherein the pixel sets of the plurality of pixel sets are separated from one another by an inter-pixel separation unit in the plan view,
wherein, in the plan view, the inter-pixel separation unit has at least four protrusions extending in each pixel set of the plurality of pixel sets, and
wherein, for each pixel set and in the plan view, the at least four protrusions extend toward a center of the pixel set.
 
20. An imaging device, comprising:
a plurality of on-chip lenses;
a plurality of color filters; and
a plurality of pixel sets arranged two-dimensionally in a plan view,
wherein each pixel set of the plurality of pixel sets includes four photoelectric conversion regions,
wherein the pixel sets of the plurality of pixel sets are separated from one another by an inter-pixel separation unit in the plan view,
wherein, in the plan view, the inter-pixel separation unit has at least four protrusions extending in each pixel set of the plurality of pixel sets, and
wherein, for each pixel set and in the plan view, the at least four protrusions extend toward a center of the pixel set.
