Processing method for performing dynamic image smoothing by utilizing overvoltage drive function, and method

The invention discloses a processing method for performing dynamic image smoothing by utilizing an overvoltage drive function, and a method. The smoothing processing device comprises a video information generator and an over drive circuit. The video information generator detects a plurality of frames of an image, the frames comprises current frames and previous frames, and, when a second value of each current frame is different from a first value at a corresponding position of each previous frame, first image information is generated; and, when the second value of each current frame is the same as the first value at the corresponding position of each previous frame, second image information is generated. The over drive circuit generates a first target value between the first value and the second value according to the first image information, the second values at the corresponding positions of the current frames of the two continuous frames are replaced by the first target value; or the over drive circuit generates a second target value according to the second mage information, the second values at the corresponding positions of the current frames of the two continuous frames are replaced by the first target value.
