COMPOSITING IMAGE DATA IN A LINEAR-LIGHT COLOR SPACE THAT PRESERVES A DESIRED LOOK

摘要

This specification describes technologies relating to compositing of image data. In general, one aspect of the subject matter described in this specification can be embodied in a method that includes generating color space transformations for respective imagery sources, wherein generating a color space transformation includes preparing first and second transforms for a given imagery source, wherein the first transform restores an original scene luminance in linear light, and the second transform adjusts chromaticities with respect to a target look color space. The method further includes obtaining at least two images corresponding to respective ones of the imagery sources; converting each of the at least two images to the target look color space using a corresponding one of the color space transformations; and compositing the converted at least two images into a single image in the target look color space.
