摘要： Light-splitting elements are arranged in at least two columns and two rows to form two pairs 1a, 1b and 1c, 1d. Each element splits incident light into light rays and makes them fall on a portion of a photosensing section right under itself and an adjacent photosensitive cell. The element 1a splits the incident light so that a primary color ray C1 and its complementary color ray C1′ enter an adjacent cell 2b and an underlying cell 2a, respectively. The element 1b makes a primary color ray C2 and its complementary color ray C2′ enter an underlying cell 2a and an adjacent cell 2a, respectively. The element 1c does the same as the element 1b. And the element 1d makes a primary color ray C3 and its complementary color ray C3′ enter an adjacent cell 2c and an underlying cell 2d, respectively. These photosensitive cells 2 perform photoelectric conversion, thereby outputting an electrical signal representing the intensity of the incident light. By carrying out simple calculations between the outputs of these cells, a color signal and a luminance signal are generated.

摘要： An imaging photodetection device includes a plurality of photodetectors (6) arrayed on a substrate (5) one-dimensionally or two-dimensionally, a low refractive index transparent layer (12) formed above the plural photodetectors, and a plurality of columnar or plate-like high refractive index transparent sections (13) embedded in the low refractive index transparent layer along the array direction of the plural photodetectors. At least two of the photodetectors correspond to one of the high refractive index transparent sections. Light entering the low refractive index transparent layer and the high refractive index transparent sections passes therethrough to be separated into a 0th-order diffracted light, a 1st-order diffracted light and a −1st-order diffracted light by a phase shift occurring on the wavefront. Thereby, improvement in the efficiency for light utilization and pixel densification can be realized.
