Abstract
A method for generating and employing a camera noise model, performed by a processing unit, is introduced to at least contain the following steps. A first frame is obtained by controlling a camera module via a camera module controller. A camera noise model is generated on-line according to the content of the first frame, which describes relationships between pixel values and standard deviations. A second frame is obtained by controlling the camera module via the camera module controller. The content of the second frame is adjusted using the camera noise model, and the second frame, which has been adjusted, is stored in a frame buffer.
