Abstract
Techniques and tools for displaying/viewing HDR images are described. In one aspect, a background image constructed from HDR image information is displayed along with portions of the HDR image corresponding to one or more regions of interest. The portions have at least one display parameter (e.g., a tone mapping parameter) that differs from a corresponding display parameter for the background image. Regions of interest and display parameters can be determined by a user (e.g., via a GUI). In another aspect, an intermediate image is determined based on image data corresponding to one or more regions of interest of the HDR image. The intermediate image has a narrower dynamic range than the HDR image. The intermediate image or a derived image is then displayed. The techniques and tools can be used to compare, for example, different tone mappings, compression methods, or color spaces in the background and regions of interest.

16. In a computer system, a method of displaying one or more high dynamic range digital images on a display, the method comprising:
-
receiving high dynamic range image information defining a high dynamic range image;
receiving region of interest information, the region of interest information defining one or more regions of the high dynamic range image;
determining an intermediate image for the high dynamic range image based on image data in the one or more regions of the high dynamic range image, the intermediate image having a narrower dynamic range than the high dynamic range image; and
displaying the intermediate image on the display. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

43. A computer-readable medium having computer-executable code for implementing a software system for displaying high dynamic range digital images on a display, the software system comprising:
-
means for receiving high dynamic range image information defining a high dynamic range image;
means for receiving region of interest information, the region of interest information defining one or more regions of the high dynamic range image;
means for determining an intermediate image for the high dynamic range image based on image data in the one or more regions of the high dynamic range image, the intermediate image having a narrower dynamic range than the high dynamic range image; and
means for causing a computer to display the intermediate image on the display.
