Multi view image display apparatus and control method thereof

摘要

A multi view image display apparatus is provided. The multi view image display apparatus includes: a depth adjuster configured to adjust a depth of an input image; a renderer configured to render a multi view image based on the input image of which depth is adjusted; a display configured to arrange a multi view image in a preset arrangement pattern in order to display the multi view image; and a controller configured to control the depth adjuster to shift the depth of the input image based on depth information related to at least one object of the input image so that an object satisfying a preset criteria has a preset depth value.

1. A multi view image display apparatus comprising:
a depth estimator configured to estimate a depth of an input image; a depth adjuster configured to adjust the estimated depth; a renderer configured to render a multi view image based the adjusted depth; and a display configured to display the rendered multi view image, wherein the depth adjuster is configured to adjust the estimated depth based on a minimum value of at least one of information calculated from a disparity histogram of the input image, periodic pattern information existing in the input image, and Markov random fields (MRF) energy information of the input image, and wherein the depth adjuster is configured to convert a threshold frequency calculated from the disparity histogram, the periodic pattern information, and the MRF energy information into attenuation coefficients, to determine a minimum value of the attenuation coefficients as a depth reduction amount, and to adjust the depth of the input image based on the determined amount of depth reduction.
