ABSTRACT:
An image sensor includes a plurality of micro-lenses and a plurality of light receiving elements. Each micro-lens has a neighboring micro-lens at a respective distance that decreases with an incident angle of light converged by the micro-lens. Each light receiving element has a neighboring light receiving element at a respective distance that increases with an incident angle of light received by the light receiving element. Such position adjustment of the micro-lenses and light receiving elements enhances photo sensitivity of the image sensor.
