Restoration and demosaicing for pixel mixture images in DSC video clips
This paper proposes restoration methods for "pixel mixture". Pixel mixture is a function for saving readout time for digital still cameras (DSCs), 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. Both restoration and demosaicing are performed at the same time. Our approach achieves the result of smaller mean square error than conventional interpolation methods.
