COLOR TRANSFORMATION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a color transformation method and apparatus wherein a coding error is reduced. SOLUTION: The color transformation method includes steps for: reading a first color component set from a predetermined memory; transforming the read first color component set to a second color component set using a predetermined transformation function; and storing the transformed second color component set to correspond to the first color component set, wherein the transformation function applied to the transforming step is defined by: defining a first transform matrix used for acquiring dominant components of a first color component using a predetermined transformation technology; and multiplying each of the elements of the defined first transformation matrix by a predetermined integer (k).
