Abstract: An image processing method is provided. The image processing method is applied to an image signal processor. The image processing method includes the stages detailed in the following paragraph. Binned-Bayer raw data and binned-white raw data are received from an image sensor with an RGBW color filter array. The binned-Bayer raw data include information of red, green, and blue channels for a plurality of pixels. The binned-white raw data include luminance information for the pixels. The pixels are rendered based on both the binned-Bayer raw data and the binned-white raw data.

Abstract: A demosaicking method for an image having a multi-cell mosaic pattern, wherein the multi-cell mosaic pattern includes a first quarter, a second quarter, a third quarter, and a fourth quarter. Each quarter includes multiple cells, and each cell includes a pixel value. The method includes: obtaining the image; performing an image-dividing process on the image to obtain four Bayer plane images; performing a quarter-resolution demosaicking process on each of the four quarter-resolution plane images to obtain a quarter-resolution image in each color channel; and performing an image-combining process on the quarter-resolution image in each color channel to generate a first full-resolution image in each color channel.
