Abstract
An image processing module is provided. A de-mosaic unit in the image processing module includes an edge direction detection unit and a multi-pixel directional interpolation unit. The edge direction detection unit is used to determine a first color row luminance difference according to a plurality of first color pixels of a pixel row of raw data, and determine a first color column luminance difference according to a plurality of first color pixels of a pixel column of raw data. The multi-pixels directional interpolation unit is used to determine pixel luminance of a third color array according to the first color column luminance difference, the first color row luminance difference, the third color pixels adjacent to a first color pixel and the third color pixels adjacent to a second color pixel.
