Abstract

An image processing method and device based on a bayer format. The image processing method based on the bayer format comprises: executing for a to be processed image a binning processing in a row direction and/or a binning processing in a column direction an arranging mode of pixels in the processed image being identical with an arranging mode of pixels in the to be processed image. The binning processing comprises: determining a location for outputting pixels; selecting in the to be processed image several pixels whose color type is identical with a color type of the output pixels to perform weighted average so as to obtain an output pixel value a location of the selected several pixels and a location of the output pixels meet a weighted average relationship. According to the technical solution of the present invention image quality is ensured after a color interpolation based on a conventional binning method without introducing any false detail.
