Abstract:
1. An image sensor comprising: (a) an array of pixels comprising a plurality of kernels that repeat periodically and each kernel includes n charge collection regions for collecting charge in response to light, n is equal to or greater than 2, wherein the charge collection regions are disposed in an active layer; (b) a transparent layer immediately on top of the active layer and spanning the charge collection regions having n optical paths for each kernel, at least two of which are different, wherein each optical path directs light of a single spectra band of different wavelengths to one or more predetermined adjacent charge collection regions; and wherein each charge collection region receives a spectral band of light containing a peak wave length corresponding to a single color, which is directed toward one optical path, and wherein the peak wavelength received by each of the adjacent charge collection regions is different, such that each charge collection region receives light having a peak wavelength corresponding to a single color.
