Patent ID: 8665262

Claim:
A depth map enhancing method, comprising: obtaining an original depth map and a depth related parameter, and storing said original depth map and said depth related parameter into a storage medium; quantifying a gray level value of every pixel in said original depth map between 0 and 1 to obtain a plurality of quantified gray level values; calculating a fraction with a numerator to be divided by a denominator, wherein said fraction is to be multiplied by a max gray level value to obtain a plurality of depth-relation-enhanced gray level values, wherein said numerator comprises raising said depth related parameter to a power of each of said plurality of quantified gray level values respectively and subtracting said raised depth related parameter by 1, wherein said denominator comprises subtracting said depth related parameter by 1; and evenly distributing said plurality of depth-relation-enhanced gray level values between 0 and said max gray level value according to a relative proportional relationship among said plurality of depth-relation-enhanced gray level values to obtain a plurality of final gray level values.
