Solid-state imaging apparatus

A solid-state imaging apparatus comprising:

• an imaging region;
• and
• a plurality of unit cells arranged two-dimensionally in the imaging region, the plurality of unit cells including a first unit cell and a second unit cell,
• wherein each of the plurality of unit cells has a light-receiving element and a light-collecting element,
• the first unit cell includes a first light-receiving element and a first light-collecting element, the first light-collecting element collects a first incident light to maximize an amount of a first light incident on the first light-receiving element when the first incident light is incident at a first angle-of-incidence,
• the second unit cell adjacent to the first unit cell includes a second light-receiving element and a second light-collecting element, the second light-collecting element collects a second incident light to maximize an amount of a second light incident on the second light-receiving element when the second incident light is incident at a second angle-of-incidence,
• an amount of the first light incident on the first light-receiving element when the first incident light is incident at a third angle-of-incidence on the first unit cell is equal to an amount of the second light incident on the second light-receiving element when the second incident light is incident at the third angle-of-incidence on the second unit cell,
• the first angle-of-incidence is greater than the third angle-of-incidence by a predetermined amount, and
• the second angle-of-incidence is smaller than the third angle-of-incidence by the predetermined amount.
