Abstract | Most consumer digital cameras use a single light sensor which captures colour information using a colour filter array (CFA). This produces a mosaic image, where each pixel contains either a red, green or blue sample. The two missing colours at each pixel location must be interpolated from the surrounding samples in a process called demosaicking. The conventional approach to compressing video in these devices is to first perform demosaicking and then compress the resulting full-colour video using standard methods. In this paper a method for compressing CFA video prior to demosaicking is proposed, using a modified version of the H.264 video coding standard. Simulations show the proposed method gives better compression efficiency than the demosaick-first approach at high bit-rates |
