Solid-state imaging apparatus

摘要

A solid-state imaging apparatus is disclosed in which, in a first unit cell, light is collected to maximize an amount of light received when the light is incident at a first angle-of-incidence, and in a second unit cell adjacent to the first unit cell, light is collected to maximize an amount of light received when the light is incident at a second angle-of-incidence, the amount of light received when the light is incident at a third angle-of-incidence on the first unit cell is equal to the amount of light received when the 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.

1. 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 directly adjacent to the first 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 directly 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.
