Abstract
In an image processing method, an image processing device obtains an input image from an image sensor. Each pixel of the input image is either a type-I pixel or a type-II pixel. Each type-I pixel carries a luminance channel value and no color data, and each type-II pixel carries a single color channel value and no luminance data, wherein the single color channel value is a cyan channel value, a magenta channel value, or a yellow channel value. The image processing device generates a target image by performing interpolation based on the luminance channel values and the single color channel values of the pixels of the input image, wherein each pixel in the target image corresponds in location to a pixel in the input image and has three color channel values generated by the interpolation.
