Method and apparatus for color space conversion

摘要

An input color space value (102) is converted to an output color space value (104) by determining (202) a most significant portion and a least significant portion associated with the input color space value (102). In addition, at least one node value is determined (204). Each node value is determined (204) at a respective counter i (122) from 0 to a maximum value associated with the least significant portion. Each node value is determined (204) to be substantially equal to: a lookup value associated with one plus the most significant portion for each counter i (122) is less than the least significant portion; and a lookup value associated with the most significant portion for each counter i (122) is greater than or equal to the least significant portion. Furthermore, the output color space value (104) is calculated (206) to be substantially equal to an average value for the at least one node value.
