Abstract:
1. A method to selectively and interactively fine-tune the tone-mapping of an image, the input image having a large dynamic range and the output image being adjusted for display on a low dynamic range display or output, comprising the steps of: a) calculating a first set of values, different from the high dynamic range input image; b) calculating a first output image as a second version of an output image with a lower dynamic range, as a function of said first set of values and the high dynamic range input image; c) displaying said first output image; d) receiving user input comprising allowing a user to indicate desired changes at locations within the image; e) calculating a second set of values based on the high dynamic range input image and said user input; f) calculating a second output image as a function of said first set of values and said second set of values; and g) displaying said second output image.
