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 camera noise model is provided. A first frame is obtained by controlling a camera module via a camera module controller. A blending ratio corresponding to each pixel value of the first frame is generated according to the camera noise model, the pixel value of the first frame and a corresponding pixel value of a second frame. A third frame is generated by fusing each pixel value of the first frame with the corresponding pixel value of the second frame according to the blending ratio. A de-nosing strength for each pixel value of the third frame is adjusted according to the blending ratio. Each pixel value of the third frame is adjusted using the corresponding de-nosing strength.
