Park et al [3] introduced refined versions to the CIECAM02 for reducing the veiling glare for mobile displays. The first was called black correction by subtracting the amount of black level from the measured tristimulus values (XYZ) and the other was a correction of J (lightness scale). The previous work was based on single colour patch samples. In this paper, an experiment was carried out using the complex images to verify the different versions of CIECAM02. The images were processed based on CIECkM02 JMh (lightness, colourfulness and hue). The experiment was conducted by comparing the original images viewed under dim, average and bright surround conditions with the predicted image viewed under dark surround condition on two identical mobile displays. The different versions of the CIECAM02 showed similar results to each other for dim and average surround conditions but large difference was found for bright surround condition. The refined CIECAM02 with J' correction performed the best amongst all four CIECAM02 versions.
