Development Of Color Management Module On Mobile Terminal Based On Android Platform

In recent years, with the development of mobile Internet and electronic technology, smart phones and tablet PCs as the representative of mobile intelligent terminal is moving forward at an alarming rate.The accurate color management of Mobile terminal screen is inseparable from the accurate characterization of the screen as well as efficient color management engine. In this paper, taking fully into account the mobile terminal hardware and software features, the matrix/TRC model based conversion algorithm was adopt.The color management engine was divided into interactive interface, document processing, color space definition, color space conversion four sub modules according to the working principle, each module collaborative complete the color conversion process of color management.The interactive interface module provides color space parameters and gamut mapping parameters; document processing module carried out image color extraction, ICC profile extraction, embedding, processing and image generation; color space definition module build attributes of color space and the conversion relationship between this color space and the PCS according to the color space parameters; color space conversion module calls the three modules to complete a full color conversion process and convert the result back to the screen interactive module displays.Subjects using the Eclipse integrated development tools and the Android Software Development Kit (SDK) realizing the CMM program. The transition effects of CMM was then compared with color management engine Adobe ACE. It was found that the new CMM achieve a higher conversion accuracy. In addition to part of a slightly brighter tone color cast, the rest are closed to Adobe CMM conversion results. That is to say the CMM achieve the desired effect.
