1. A method for forming a digital color image comprising:
- capturing an image using a solid state image sensor having a pixel array that includes both panchromatic pixels and color pixels, wherein the color pixels correspond to at least two color photoresponses and wherein the pixel array is made up of a plurality of tiled minimal repeating units, each minimal repeating unit including a plurality of cells, each cell including at least two panchromatic pixels and at least two pixels having the same color photoresponse, wherein the minimal repeating unit is

Abstract
A method for forming a final digital color image includes capturing an image using an image sensor having panchromatic pixels and color pixels corresponding to at least two color photoresponses; providing from the captured image a digital panchromatic image and an intermediate digital color image; and using the digital panchromatic image and the intermediate digital color image to provide the final digital color image.
