Abstract: A method and an apparatus for obtaining a depth image by using a time-of-flight sensor may generate a depth image based on a plurality of images in which a motion blur area caused by a movement of an object was corrected. In this case, since the motion blur area is corrected after an initial phase difference of emitted light is compensated, an accuracy of the depth image may be enhanced.

Abstract: A method of processing a stereoscopic video includes determining whether a current frame of a stereoscopic video is a video segment boundary frame; determining whether an image error is included in the current frame when the current frame is the video segment boundary frame; and processing the current frame by removing, from the current frame, a post inserted object (PIO) included in the current frame when the image error is included in the current frame.
