This paper proposes demosaicing methods for video clip of digital still cameras (DSCs). In video clips of DSCs,
pixel mixture is performed for saving readout time, which mixes together two pixels on CCD. Pixel mixture
reduces the number of pixels to be read out from CCD, and it enables video rate read out from DSCs of more
than a million pixels. In this paper, an iterative method is presented in order to recover the image. Our approach
achieves the results of smaller mean square errors than conventional interpolation methods.
