Apparatus, system, and moving body

An apparatus comprising:

• a plurality of pixels on a substrate, wherein
• each of the plurality of pixels includes
• a first portion,
• a second portion, and
• a microlens,
• the substrate
• has a first surface on an incidence side and a second surface opposite to the first surface, and
• includes
• an inter-pixel portion isolating adjacent pixels from each other among the plurality of pixels, and
• an intra-pixel portion isolating the first portion and the second portion from each other,
• the inter-pixel portion includes
• a first region located adjacently to the first surface in plan view from the first surface, and
• a second region located adjacently to the second surface,
• the first region is shifted with respect to the second region,
• the intra-pixel portion includes
• a third region located adjacently to the first surface, and
• a fourth region located adjacently to the second surface,
• the third region is shifted with respect to the fourth region in a direction identical to a shift direction of the first region, and
• the shift direction is a direction orthogonal to a longitudinal direction of the intra-pixel portion in plan view from the first surface.
