Abstract: An output circuit includes first and second output drivers. The first output driver is configured to transfer a first data signal directly to an output pad in synchronization with a clock signal. The second output driver is configured to transfer a second data signal directly to the output pad in synchronization with an inversion clock signal. The clock signal and the inversion clock enable multiplexing of the first data signal and the second data signal to provide a multiplexed output data signal.

Abstract: Provided is a stereo matching method and apparatus. A stereo matching method includes acquiring detection information based on an edge detection of a first image, determining an edge line and a feature point based on the detection information, sampling a reference pixel from the edge line and the feature point, determining a polygon with the reference pixel as a vertex, predicting a search range comprising a disparity of a pixel within the polygon based on a disparity of the reference pixel, and performing stereo matching of the pixel based on the search range.

Abstract: A shadow information storing method and apparatus is disclosed. The shadow information storing apparatus determines a shadow area through rendering a three-dimensional (3D) model based on light radiated from a reference virtual light source, determines a shadow feature value of a vertex of the 3D model based on a distance between a location of the vertex of the 3D model and the shadow area, and stores the determined shadow feature value.
