    摘要: The invention provides an image processing apparatus for processing an interlaced video which includes a judging module, a determining module and a processing module. The judging module is used for judging if a pixel in the kth frame among P frames of the interlaced video relates to a moving object. If the result judged by the determining module is YES, the determining module determines one between two pixels adjacent to the judged pixel in the frame as an edge pixel relative to an edge of the moving object. The first processing module is used for calculating a gray scale of the edge pixel determined by the determining module in an average way.

    摘要: The invention discloses a noise reduction device for adjusting gray levels of a video sequence to reduce noises. The noise reduction device of the invention includes a motion detector and a first noise reduction module. The motion detector is used for determining whether an inputted pixel is a motion pixel or a static pixel. If the pixel is a motion pixel, the first noise reduction module directly outputs the pixel without adjustment. If the pixel is a static pixel, the first noise reduction module adjusts the gray level of the pixel according to previous image frame. Because the invention only stores previous image frame, and does not utilizes multiple continuous image frames to adjust the present image frame. Therefore, the display system of the invention needs only to be installed with one buffer, and hardware resource can be further saved.
