GENERATING METHOD FOR DISPARITY MAP

摘要

PURPOSE: A time difference map creation method is provided to realize low power effects by reducing memory bandwidth which is necessary to read images by reducing a search range. CONSTITUTION: A stereo image is inputted(S1). An ESR(Effective Search Range) which is used for hamming distance computation on the stereo image is determined. A time difference map is created using the ESR. A low-resolution reduction image for the stereo image is created(S2-1). A histogram is created for the low-resolution reduction image(S2-2). The EST is determined using the histogram(S2-3).
