A color transformation method of transforming a first color component set
representing a first color space to a second color component set
representing a second color space is provided. The method comprising:
reading the first color component set; transforming the read first color
component set to the second color component set using a predetermined
transformation function; and storing the second color component set to
correspond to the first color component set, wherein the transformation
function is defined by: defining a first transformation matrix used for
acquiring dominant components of the first color component set and
multiplying each of the elements of the determined first transformation
matrix by a predetermined integer k. The method further comprises
inverse-transforming the second color component set to the first color
component set.
