CFA correction for CFA images captured at partial resolution

Year	Description
1998	Invention patented by Craig M. Smith and James E. Jr. Adams on March 26th, 1998. Abstract: In a method for generating color image signals derived from an array of color image pixels, the array of color pixels are subsampled in order to generate an array of subsampled color pixels. An array of new, evenly spaced color pixels are interpolated from the subsampled color pixels using surrounding pixels of the same color, and the color image signals derived from the array of new color pixels are subsequently processed, e.g., in a color filter array interpolation. By providing this correction in a preprocessing step, the rest of the normal image processing hardware or software may be used on the resultant subsampled CFA image without developing the characteristic blocky and wavy artifacts caused by an irregular subsampling pattern.
