Abstract
An image sensor includes filters formed over a portion of an array of photosensitive elements in a predetermined pattern. The pattern can be such that the exposure of a matrix (such as a 2-by-2 square of pixels) to light (such as blue light) is improved, while maintaining acceptable capability to capture light across the entire spectrum. The pattern can be such that two blue filters, one red, and one green filter is used by a 2-by-2 square matrix of pixels. The pattern can also include cyan, yellow, and magenta (CYM) filters.
