  • Patent number: 8280182
    Abstract: An image processing method of noise reduction and an apparatus thereof are disclosed herein. In the image processing method, a current image having a plurality of image blocks is provided. A first block of the image blocks of the current image is substrate by the first block of at least one previous image for obtaining a difference block. Next, the difference block is performed on a motion detection process for determining whether the first block of the current image is in a static state. When the first block of the current image is in the static state, the first block of the current image is performed on a temporal filtering process for reducing the noise. By analyzing the static state, occurrence of motion blur can be prevented.
