A Color Error Correction Mode for Digital Camera Based on Polynomial Curve Generation

Digital camera is one of the main devices in computer and multimedia technology and its color management model is the key to guarantee color consistency in succedent image production and transfers. The paper presents a color conversion model for digital camera based on polynomial curve generation. Firstly, color rendering principle of digital camera is analyzed. Then digital camera data is pretreated to a unitary field to deduce final model. Thirdly, standard color target is taken for experimental sample and substitutes color blocks in color shade district for complete color space to solve the difficulties of experimental color blocks selecting; Fourthly, the model using polynomial curve generation algorithm to correct color error is deduced; Finally, the realization and experiment results show that, compared with some methods which have relatively high accuracy, the algorithm can improve color conversion accuracy and can satisfy the engineering requirement in digital camera color management .
