Method and apparatus for converting color spaces and multi-color display

摘要

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 (m<n) are provided. The method comprises extracting first through nth intermediate color components by linearly combining the first through m-th input color components; determining whether the m+1-th through n-th intermediate color components are within a predetermined 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. The color conversion to a higher-dimensional output color space is simplified.
