Abstract
A first motion detection is performed for determining a motion or a still condition by comparing a difference signal .DELTA. between an input video signal of a current frame and a video signal of a previous frame with a preset threshold value. A second motion detection is performed for determining a motion or a still condition by using a difference signal .DELTA. between an input video signal of a current frame and a video signal of a previous frame at surrounding pixels and a center pixel as a target for the second motion detection. A wrong decision correction is performed for correcting an error in a result of motion detection in the first and/or second motion detections by changing a determination of a motion condition to a still condition, or a determination of a still condition to a motion condition, wherein an error is either a wrong determination of a motion condition for a still condition or a wrong determination of a still condition for a motion condition. A transition period detection is performed for detecting a motion-to-still transition period for a pixel whose data is determined as still during the correcting of a wrong decision.
