A circuit for outputting overdrive voltages of a liquid crystal panel includes a memory unit and an overdrive unit. The overdrive unit includes a first lookup table, a second lookup table, and a selector. The memory unit stores a plurality of second pixel voltages corresponding to a second frame displayed by the liquid crystal panel and outputs a plurality of first pixel voltages corresponding to a first frame displayed by the liquid crystal panel stored in the memory unit. The overdrive unit looks up the first lookup table and the second lookup table to generate a first overdrive voltage and a second overdrive voltage according to each first pixel voltage and a corresponding second pixel voltage. The selector outputs the first overdrive voltage or the second overdrive voltage according to a polarity signal and a frame signal.

An overdriving apparatus including a memory unit, a position unit and an overdriving unit is provided. The memory unit stores a present frame received and outputs a previous frame stored in the memory unit. The position unit generates pixel position information according to a display control signal of the present frame. The overdriving unit determines a corresponding relationship between several pixel grey values of the present frame and several display areas of a display panel according to the pixel position information, so as to select a corresponding specific table group of each of the pixel grey values from a plurality of overdriving tables. The overdriving unit further generates an overdriving frame by looking up the corresponding specific table group of each of the pixel grey values.

A method for generating a 3D image utilizes a background image and an object image. A camera is used for capturing a 2D image including the background image and the object image. The object image is obtained from the 2D image according the background image. Then, an image from a first angle of view and an image from a second angle of view are generated by rendering the background image and the object image. So, the 3D image is generated by interweaving the image from the first angle of view and the image from the second angle of view.
