Color filter array and image receiving method thereof

摘要

A color filter array, for an image sensing device, includes a plurality of filter patterns. Each filter pattern includes at least one first filter, corresponding to a first wavelength range of a first color; at least one second filter, corresponding to a second wavelength range of a second color; at least one third filter, corresponding to a third wavelength range of a third color; at least one fourth filter, corresponding to a first infrared wavelength range, wherein the first infrared wavelength range is an intersection of the first wavelength range and the second wavelength range; and at least one fifth filter, corresponding to a second infrared wavelength range, wherein the second infrared wavelength range is an intersection of the first wavelength range and the third wavelength range.
