A method and apparatus for reproducing a stereoscopic image are provided. The method includes generating information about parallax between a left-eye image and a right-eye image of objects included in the stereoscopic image based on a stereo camera parameter of the stereoscopic image, controlling the depth of the objects in the stereoscopic image based on the generated information, and reproducing the stereoscopic image based on the controlled depth. Accordingly, the stereoscopic image can be reproduced while minimizing the eye fatigue of a viewer.

Provided is a method and apparatus for determining stereo views of a stereoscopic image. The method includes: selecting a pair of first and second images from a pair of frames of the stereoscopic image, the pair of frames including a base view image and an additional view image. The method further includes determining which of the first image and the second image is the base view image and which of the first image and the second image is the additional view image based on a parallax between the pair of first and second images.

Provided are an apparatus and method for driving a 2-dimensional (2D)/3-dimensional (3D) switchable display for improving the quality of image. The apparatus for driving a 2D/3D switchable display includes: an image mode determination unit determining whether input image signals of continuous frames are in a 2D mode or 3D mode; and an over-driving control unit over-driving the input image signal of a current differently according to the determined image mode. According to the apparatus and method, the response time in each of the 2D mode and the 3D mode can be increased, while motion blur and cross-talk effects can be decreased, thereby improving the quality of image.

An apparatus and method for driving a liquid crystal display to improve the quality of moving pictures are provided. The apparatus includes a transition check unit that determines whether an input image signal between a first frame and a second frame has changed and whether an input image signal between the second frame and a third frame has changed; an overdrive control unit that overdrives the input image signal in the second frame in an overdrive direction if the transition check unit determines that the input image signal between the first and second frames has changed, wherein the overdrive direction is one of an upper direction and lower direction; and an overdrive compensation unit that changes the input image signal in the third frame in an opposite direction to the overdrive direction if the transition check unit determines that the input image signal between the second and third frames has not changed.
