Abstract

Electrical Phase Detection Auto Focus. In one embodiment, an image sensor includes a plurality of pixels arranged in rows and columns of a pixel array disposed in a semiconductor material. Each pixel includes a plurality of photodiodes configured to receive incoming light through an illuminated surface of the semiconductor material. The plurality of pixels includes at least one autofocusing phase detection (PDAF) pixel having: a first subpixel without a light shielding, and a second subpixel without the light shielding. Autofocusing of the image sensor is at least in part determined based on different electrical outputs of the first subpixel and the second sub pixels.
