Abstract:
An image sensor includes an array of pixels comprising a plurality of kernels that repeat periodically and each kernel includes n photosensitive regions for collecting charge in response to light, n is equal to or greater than 2; and a transparent layer spanning the photosensitive regions having n optical paths, at least two of which are different, wherein each optical path directs light of a predetermined spectral band into specific photosensitive regions.
