Abstract: Method and apparatus for partial lens shading compensation are provided. An image area is divided, from the inside towards the outside of the image area, into several partial areas centered on an optical center of the image. When a target pixel is identified as being located in one of the partial areas, a corresponding compensation gain is determined according to the position of the target pixel with reference to the optical center. Another compensation gain is determined according to the position of the target pixel with reference to the optical center. A mixed compensation value is determined according to the compensation gains, so as to compensate the target pixel.
