Claim:
1. A device using an overdrive function to do smoothing processing of video data, comprising: a video information generator, detecting a plurality of continuous frames wherein the continuous frames include a current frame and a previous frame; when a second value of the current frame is different from a first value of the previous frame having the same position as that of the second value, the video information generator generates first video information; when the second value of the current frame is the same as the first value of the previous frame having the same position as that of the second value, the video information generator generates second video information; and an over drive circuit, generating a first target value which is a value between the first value and the second value according to the first video information, and using the first target value to replace the second value of the current frame; or generating a second target value according to the second video information, and using the second target value to replace the second value of the current frame, wherein the over drive circuit includes a first look-up table and a second look-up table, a change state of two continuous frames is defined as a state where the first value and the second value are different, the first look-up table comprises the first target value of the change state, a repeat state of two continuous frames is defined as a state where the first value and the second value are the same, and the second look-up table comprises the second target value of the repeat state.
