    Abstract: Improved methods and apparatus for digital focal plane array (FPA)—based color imaging include the step of sampling an image, using an FPA camera equipped with a color filter array (CFA) to obtain a value at each pixel position, thereby creating a set of values sampled on a per-pixel basis. Single-color cyan, yellow and white (CYW) color planes are generated from the set of sampled pixel values. Interpolates among and between the color plane values is executed to “fill in” the “gaps” in the individual color planes, and the interpolated CYW values from the single-color planes are transformed into RGB values which can be stored, transmitted, or utilized to drive a conventional video monitor or color printing device. Filtering and other post-interpolation steps are executed to reduce color aliasing, and the white plane is used to introduce high frequency content back into the filtered color image.
