Patent ID: 7538363

Claim:
A solid-state imaging device, comprising: a plurality of light-receiving parts arranged in an array in a substrate and performing photoelectric conversion on incident light; and a plurality of color separators each provided for adjacent four of the light-receiving parts arranged in two rows and two columns, wherein the four light-receiving parts are a first light-receiving part, a second light-receiving part, a third light-receiving part and a fourth light-receiving part, each of the color separators includes a first optical element part for guiding incident light to a first optical path entering the first light-receiving part, a second optical element part for guiding incident light to a second optical path entering the second light-receiving part located in a row and a column which are different from a row and a column on which the first light-receiving part is located, a first light-absorbing filter formed on the first optical path, absorbing light of a first color of the three primary colors of light and transmitting second and third colors of the three primary colors of light; a second light-absorbing filter formed on the second optical path, absorbing light of the second color and transmitting light of the first and third colors; a first color-separating element formed between the first light-absorbing filter and the first light-receiving part, transmitting light of the third color to have the transmitted light enter the first light-receiving part, reflecting light of the second color to guide the reflected light to a third optical path crossing the first optical path; a second color-separating element formed between the second light-absorbing filter and the second light-receiving part, transmitting light of the third color to have the transmitted light enter the second light-receiving part, reflecting light of the first color to guide the reflected light to a fourth optical path crossing the second optical path; a first mirror element formed on the third optical path, having light traveling on the third optical path, and having the reflected light enter the third light-receiving part located on the row on which the first light-receiving part is located and a column different from the column on which the first light-receiving part is located, and a second mirror element formed on the fourth optical path, reflecting light traveling on the fourth optical path, and having the reflected light enter the fourth light-receiving part located on the row on which the second light-receiving part is located and a column different from the column on which the second light-receiving part is located.
