Patent ID: 7019279

Claim:
A solid-state image sensor comprising a photosensitive array for capturing incident light from a desired scene, said photosensitive array comprising a plurality of photo-sensors arranged in a direction of row and a direction of column, and microlenses formed respectively on the photo-sensors, each of said plurality of photo-sensors corresponding to a particular pixel included in the photosensitive array, each of said plurality of photo-sensors comprising a first photosensitive cell having first sensitivity for photoelectrically transducing the incident light, and a second photosensitive cell having second sensitivity lower than the first sensitivity for photoelectrically transducing the incident light, each of said microlenses causing the incident light to converge to both the first and second photosensitive cells of the corresponding photo-sensor, each of said microlenses having an optical center shifted from a center of corresponding one of said plurality of photo-sensors toward a center of said photosensitive array.
