Abstract
A semiconductor imaging sensor utilizes a color filter pattern. The imaging sensor includes light sensitive-elements, each of which is sensitive to photon energy in a spectral region or color band associated with the light-sensitive elements. Select light-sensitive elements in the array are sensitive to energy in a wide band spectral region or “white” color band. This permits the capture of color information which can be lost with the use of typical semiconductor imaging sensors in digital photography. This capture of the additional color information in digital photography allows for better quality of reproduction of an image on a selected medium such as color prints.
