Abstract
A temporal noise reduction method and a temporal noise reduction device are provided. The temporal noise reduction device includes a temporal filter unit that performs a temporal filtering operation using pixel values (CP) of an N×M array in a current frame and pixel values (FP) of an N×M array located at the same position in a neighboring frame separated by a distance TP from the current frame and a motion filter unit that detects a motion of a pixel image from the resultant values of the temporal filter unit and that eliminates noise of a motion-abundant pixel value using a spatial filter. It is possible to effectively reduce noise of an image to prevent deterioration in image quality of the image and to improve performance of post-processing techniques.
