Abstract:
1. A noise elimination method of an image sequence, for eliminating electronic noises on an image sequence captured by an image sensor having a color filter array (CFA), comprising: Step A: acquiring a raw image data captured by the image sensor, so as to obtain a raw image data of a current frame as an input frame and a raw image data of a previous frame, defining the raw image data of the current frame as a base image, and defining the raw image data of the previous frame as a reference image; Step B: performing an interframe luma processing step, so as to respectively convert the base image and the reference image into a full luma base image and a full luma reference image represented by gray-scaled luminance values, comprising: Step C: performing a full RGB generation step, wherein a difference operation is performed on the base image and the reference image by using the full luma base image and the full luma reference image generated in Step B, so as to generate a noise-free full RGB image as an output frame to replace the raw image data of the current frame, wherein a frame rate of the input frame and a frame rate of the output frame is the same, and Step C comprises:
