Abstract

Digital color imaging technology has become omnipresent in today’s modern life. Digital image capturing and reproduction devices such as smartphones, digital still and video cameras, displays, printers, and color scanners can be found in every home, offering extremely high functionality and flexibility. In order to guarantee qualitatively good results regarding the whole image processing pipeline and to achieve high user acceptance, optimized color conversion and correction algorithms play a crucial role. In this context, a new implementation method of uniform three-dimensional lookup tables (3D-LUTs) based on a standardized pre-measured spectral reflectance database will be presented and applied for the color correction of digital camera systems. The strengths and limitations of such an implementation will be discussed and a performance comparison with the standard 3×3 matrix color correction will be conducted. It can be found that the proposed 3D-LUT approach outperforms the matrix method in terms ofCIEDE2000 color differences and color reproduction properties, but still has its limitations when it comes to achromatic colors and the representation ofcolor gradients.
