Abstract
A method and apparatus for converting an m-dimensional color space comprising first through m-th input color components to an n-dimensional color space comprising first through n-th output color components. specified A method of converting an m-dimensional color space having first through m-th input color components into an n-dimensional color space having first through n-th output color components, m being less than n, includes: extracting first through nth intermediate color components by linearly combining the first through m-th input color components; determining whether m+1-th through n-th intermediate color components are within a specified dynamic range and compensating the first through n-th intermediate color components when signal values of the m+1-th through n-th intermediate color components are not within the dynamic range to obtain the first through n-th output color components.
