A Color Error Correcting Model for Scanning Input Image

Based on analyzing the color rendering principle of scanning objects and the causes of color error, a new algorithm of color space conversion for scanning image is proposed. First, some parameters of Neugebauer equation and Yule-Nielson equation are reinterpreted which makes them able to be used for non-dot image and which can only be used for dot image originally. Then, the paper presents the deduction procedures of the color correction equation. Finally the experimental results show that the algorithm may result in more accurate approximation compared with some typical and mainstreams.
