Abstract
The present invention relates to an apparatus and a method for classifying pixels in each frame of a motion picture as foreground or background. According to the invention, the apparatus has a decision unit and adjustment unit. The decision unit classifies a pixel as a foreground pixel, a background pixel or an undefined pixel based on a first threshold, a second threshold and a distribution value of the pixel representing an occurrence probability of a pixel value of the pixel. The decision unit sorts each pixel into a foreground pixel or a background pixel based on the classification result of the decision unit.
