Abstract
A photosensor having a plurality of light sensitive pixels each of which comprises a light sensitive region and a plurality of storage regions for accumulating photocharge generated in the light sensitive region, a transfer gate for each storage region that is selectively electrifiable to transfer photocharge from the light sensitive region to the storage region, and an array of microlenses that for each storage region directs a different portion of light incident on the pixel to a region of the light sensitive region closer to the storage region than to other storage regions.
