Abstract
A method of motion detection using motion information of neighboring pixels, adaptive for determining whether a plurality of target pixels in a current field are moving pixels, is provided. First, it is determined whether a neighboring pixel in a previous field corresponding to the target pixel in the current field is the moving pixel. If the neighboring pixel in the previous field is the moving pixel, the target pixel is determined as the moving pixel and otherwise it is further determined whether the neighboring pixels around the target pixel in the current field are the moving pixels. If the neighboring pixels in the current field are the moving pixels, then the target pixel is determined as the moving pixel. Accordingly, the mistakenly judged static pixels can be found and modified to moving pixels, such that the accuracy of motion detection can be increased.
