摘要：
The method, system and apparatus embodiments of the present invention provide for rendering original images having high dynamic range into display images having lower dynamic range while retaining a visual quality of rendered images comparable to the original or reference images. Tone-mapping parameters are applied to the display images and are iteratively adjusted in order to reduce the differences between the conditioned original image and the conditioned display image.
