In digital color imaging pipeline, de-mosaic processing is one of the crucial steps especially in terms of digital image output quality. Authors demonstrate the de-mosaic processing in digital imaging can be functionally identical to anti-aliasing filtering in digital signal processing. Also, based on multidimensional signal processing theory, optimal filters for the de-mosaic processing are proposed, which are a rectangular-shape filter for the red and blue channel and a diamond-shape filter for the green channel.
