摘要： A method of transforming the color appearance of a plurality of digital images includes receiving a plurality of digital images from a capture medium wherein each digital image includes a plurality of pixel values relating to at least three basic colors; calculating a color correction transform by using a non-linear adjustment that is independent of the digital images and which corrects an under-exposure condition as a function of the capture medium; and a linear functional relationship dependent upon the pixels of the basic colors, the linear functional relationship defining an exposure-level-dependent estimate of gray corresponding to the photographic response of the capture medium; and using the color correction transform to modify the pixels of the plurality of digital images wherein the pixels within a digital image are transformed with varying degrees of color modification as a function of exposure.

摘要翻译：一种变换多个数字图像的颜色外观的方法包括从捕获介质接收多个数字图像，其中每个数字图像包括与至少三种基本颜色相关的多个像素值; 通过使用独立于数字图像的非线性调整并根据捕获介质校正曝光不足的条件来计算颜色校正变换; 以及取决于所述基本颜色的像素的线性函数关系，所述线性函数关系定义与所述捕获介质的照相反应相对应的与曝光级相关的灰度估计; 以及使用所述颜色校正变换来修改所述多个数字图像中的像素，其中数字图像内的像素以不同程度的颜色变化作为曝光的函数被变换。
