Abstract
An image processing method is provided, wherein the image processing method includes the steps of: receiving raw image data from an image sensor, wherein the image sensor is a four-cell Bayer sensor, the raw image data includes color information of each pixel, and the color information of each pixel only corresponds to a single color; for a specific pixel to be processed, selecting a region including the specific pixel; referring to a position of the specific pixel to determine whether to flip color information within the region to generate a flipped region; and using color information of at least one portion of pixels within the region or the flipped region to perform an interpolation operation, to generate color information that the specific pixel lacks.
