Abstract: An image processing method for reducing distortion of a depth image may include: obtaining a plurality of original images based on light beams which are emitted to and reflected from a subject; determining original depth values of original depth images obtained from the plurality of original images, based on phase delays of the light beams, the reflected light beams comprising multi-reflective light beams that distort the original depth values; determining imaginary intensities of the multi-reflective light beams with respective to each phase of the multi-reflective light beams, based on regions having intensities greater than a predetermined intensity in the original depth images; correcting the original depth values of the original depth images, based on the imaginary intensities of the multi-reflective light beams; and generating corrected depth images based on the corrected original depth values.

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.
