Most commercial digital still cameras use a single sensor array (e.g., CMOS or CCD) with color filter array (CFA) to reduce the cost and size. Since the image obtained with CFA has only one color value per pixel, the demosaicing is needed to acquire missing two color values. Although many demosaicing methods have been proposed, they still have artifacts such as rainbow and zippering artifact. In this...
To obtain the full color image, at least three channels are required at each color location, however the image sensor obtains only the intensity of the brightness and cannot separate color information, three image sensors are required per pixel to capture the full color image. Since the image sensor is expensive, most of digital still cameras (DSCs) adopt single image sensor array with color filter...
Most digital camera uses the color filter array to reduce the cost and size. When we use the color filter array, however, we need to interpolate the missing pixels. In this paper, we propose an enhanced directionally weighted demosaicing algorithm for the color filtered images of the single-sensor digital camera. The noise can be mixed to the captured image and the min, max, and min-max filters are...
