Foreground/background image selection apparatus of segmentation based coding method

The invention region segmentation views of the encoding method / background to an image selection device, a partition for receiving the motion image input in a frame unit area after the area dividing means for outputting the each area information, for each pixel and a previous frame of the current frame the total number of pixels in each pixel one-to-one correspondence to a one-to-one correspondence with the motion which detects the movement whether between each pixel of the by-pixel gapcha between the pixel current frame and the previous frame detection means, the respective regions divided by the region division means to the respective the number of pixels the ratio of the motion is detected in the region by calculating each for the same area much movement for detecting the motion degree for each area detection means, is greater the motion degree than the preset value or equal to the background if the judgment is small in view and optionally it characterized in that the configuration having a foreground / background selection means.
