The Reacher Of ICC Profile For Display Screen

With rapid development of the technology of communication, computer, microelectronics, the integrated circuit and the software,Mobile terminal is converting from simple call into a comprehensive information service platform.Nowadays our country has become one of the world’s largest market of smart-phone. With the popularity of mobile terminals, people began to use mobile terminal products to online shopping, and even as an electronic photo album.It has been found that the image color which the human eye can see from the monitor is inconsistent in different environments. What’s more, different mobile terminals and terminals of different brands often have a big gap in color reproduction ability. Therefore, how to get exact and accurate reproduction of image color on different mobile terminal in a complex environment, become an urgent problem to study and resolveBefore color management for mobile terminal, it is necessary to generate ICC prfile for color managementBut some existing ICC creating soft cannot meet the mobile terminal ICC color management system to automatically generate properties file and transfer to the android requirement,such as ProfileMaker and il Profiler. So we need to write a program to create the ICC profile.The task of this research is to write a software which is used to generate the ICC Profile for Android devices.To achieve this target,the first thing I need to do is to study Version4.3of ICC Profile format carefully and understand the color rendering principle and characteristics of monitor first.Then generate two kinds of profiles based on the matrix and look-up table feature according to the specific format requirements.This right and useful profiles will get the targets which is that reproduce the image color Accurately on the android system.At last after the process completed, this paper evaluated the characteristics of two types of profiles on the computer screen due to the android correction unfinished.The accuracy of the profile based on the matrix is better than it of the profile based on clut.The reason is the grid points of the profile generated by the issue is few.Then the profile based on the matrix can satisfy the precision of color management.
