Abstract:
1. A solid-state imaging device comprising: a plurality of pixels arranged in an array, each of the pixels including a light-receiving section and an on-chip lens, the on-chip lens being formed on an object side of the light-receiving section, wherein for each of the pixels, the on-chip lens has a lens surface that is defined by a surface function described by a predetermined mathematical function that depends on a distance between the center of the array of pixels and the center of the on-chip lens, and the refractive index of the on-chip lens, wherein for each on-chip lens, the predetermined mathematical function further depends on an incident angle θ wherein for each on-chip lens, the predetermined mathematical function further depends at least in part on a term defined by the mathematical function of where y is the distance between the center of the array of pixel and the center of the on-chip lens and n is the refractive index of the on-chip lens.
