Patent ID: 8837816

Claim:
A method for generating a final depth information related map, comprising: receiving a coarse depth information related map, wherein a resolution of the coarse depth information related map is smaller than a resolution of the final depth information related map; and outputting the final depth information related map reconstructed from the coarse depth information related map by receiving an input data and performing a guided interpolation operation upon the coarse depth information related map according to the input data; wherein the step of performing the guided interpolation operation upon the coarse depth information related map according to the input data comprises: determining a plurality of image characteristics according to values located at a plurality of first locations and a second location in the input data; determining parameters of a guided weighting function according to the image characteristics; and generating an interpolated value in the final depth information related map that corresponds to the second location by utilizing an interpolation unit to perform the guided interpolation operation according to the guided weighting function and values in the coarse depth information related map that correspond to the first locations respectively.
