Color Management For Camera Based On ICC Optimization

Color management is an important way to achieve cross-platform and cross-device color reproducible. Has been color fidelity transmission and reproduction is research and the pursuit of the goal of color management. Different devices have their own different device characteristics. Moreover, even with an apparatus, not the same length of time, the use of consumables not the same, the color rendering properties are not the same. This resulted in the same original color on different devices will produce a completely different eye color perception. The ultimate goal of color management is to ensure accurate color reproduction and transmission between different devices, wanted to make sure the same colors on different devices give people produce the same eye color perception, achieve WYSIWYG the final results.Color management has been more mature set of processes, under normal circumstances to meet the color management needs of ordinary users. But in some special areas, general color card can not be used in common processes to meet people for input devices (such as digital cameras) color management requirements. Mainly use fewer patches to express all colors throughout the human eye can perceive the universal color card. Its main drawback is the lack of precision color reproduction. To solve these problems, this paper focuses on the digital camera color management. Detail the theoretical basis of color and specification for ICC color management. And analyzes the advantages and disadvantages of common color card for its shortcomings, this paper proposes the use of home-made for a specific scene spot color card for color management. Since the method is given for spot color card, on this basis, proposes the use of spot color cards generate the corresponding properties files. Not only of the principles and operation flow of this method is described in detail, but also the feasibility of using this method is proved.
