精确的色彩再现图像呈现在
计算机控制的CRT显示器作为投影的35-mm分辨率是一个复杂的过程，需要表征和控制几个成像过程，并应用适当的颜色外观建模来考虑观看条件的变化。我们回顾了图像记录仪表征，投影系统表征和测试的颜色外观模型的应用程序的过程。通过曝光和处理系统的经验模型和照相胶片的物理模型的结合，实现了精确的图像记录仪表征。投影系统的特性包括光源的光谱特性、观看屏幕的反射特性以及曝光和温度对摄影分辨率的影响。颜色外观模型用于预测由于媒体、白色点、亮度和环境的变化而导致的图像颜色外观的变化。RLAB模型证明在此应用中效果最好。
Accurate color reproduction of images presented on a
computer-controlled CRT display as projected 35-mm transparencies is a complicated procedure requiring the characterization and control of several imaging processes and the application of appropriate color appearance modeling to account for the changes in viewing conditions. We review a process for image recorder characterization, projection system characterization, and testing of color appearance models for this application. Accurate image recorder characterization was achieved through a combination of empirical modeling of the exposure and processing system and of a physical model of photographic film. The projection system characterization included specification of the spectral properties of the light source, reflectance properties of the viewing screen, and the effects of light exposure and temperature on the photographic transparencies. Color appearance models were used to predict the changes in image color appearance due to changes in media, white point, luminance, and surround. The RLAB model proved to work best in this application.
