  • METHOD AND APPARATUS FOR PROCESSING MULTI-VIEW IMAGE USING HOLE RENDERING
    Publication number: 20130016897
    Abstract: A method and apparatus for processing a multi-view image are provided. A priority may be assigned to each hole pixel in a hole region generated when an output view is generated. The priority of each hole pixel may be generated by combining a structure priority, a confidence priority, and a disparity priority. Hole rendering may be applied to a target patch including a hole pixel having a highest priority. The hole pixel may be restored by searching for a source patch most similar to a background of the target patch, and copying a pixel in the found source patch into a hole pixel of the target patch.

  • Apparatus and method for ambient light adaptive color correction
    Patent number: 8243210
    Abstract: An ambient light adaptive color correction system and method are provided in the present invention. Firstly, a color information sensor measures color information of at least black and white reference images on a projector plane with influence of ambient light. Then a color correction information calculator calculates color correction information for color appearance matching and gamut mapping based on the measured color information and a projector profile. And after pre-calculation, an image data correction unit processes an input image according to the color correction information to produce a corrected-color image to be outputted to the projector. Accordingly, the output image displayed on the projection plane with influence of ambient light will have a close color appearance to that in the dark room.
