Noise elimination method of image sequence

A noise elimination method of an image sequence, for eliminating 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 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;
• and
• Step C:
• performing a full RGB generation step, wherein an interpolation process 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.
