SOLID-STATE IMAGE SENSING ELEMENT AND IMAGE SENSING APPARATUS |
摘要 |
<p>An image sensor that output a signal for detecting a focus state of a photographing lens. The image sensor includes a microlens; a light-receiving pixel; a first focus state detection pixel pair for outputting a focus state detection signal, in which aperture areas of the first focus state detection pixel pair are small in comparison to the light-receiving pixel; and a second focus state detection pixel pair for outputting a focus state detection signal, in which aperture areas of the second focus state detection pixel pair are small in comparison to the light-receiving pixel, wherein the second focus state detection pixel pair is arranged at a position that is shifted by a predetermined amount relative to each aperture position, with respect to the microlens of the first focus state detection pixel pair.</p> |
