Abstract: A method for generating a three-dimensional (3D) image may detect a current eye position of a user and render a 3D image based on at least one of a previously detected eye position of the user and previously generated stereo images. A cycle at which the current eye position of user is detected and a cycle at which a 3D image is rendered may be asynchronous.

Abstract: An image processing apparatus may include a sensor unit which generates both a color image and a depth image. A color-depth time difference correcting unit may correct a mismatching that occurs due to a time difference between a point in time when the color image is generated and a point in time when the depth image is generated. An image generator may generate a stereoscopic image or a multi-view image using the color image and the depth image after the mismatching is corrected.
