Patent ID: 7978202

Claim:
A high dynamic range image editing system for editing a high dynamic range image data having pixels spanning a first range of light intensity levels, the high dynamic range image editing system comprising: a scaling control operable by the user that allows the user to specify one of several scaling factors; a scaler in communication with the scaling control configured to create a scaled version of the image data that has pixel intensity levels that are scaled from their original values in accordance with the scaling factor specified by the user on the scaling control; a display configured to display the scaled version of the image data which only displays differences in light intensity levels of pixels within a second range of light intensity levels which is less than the first range of light intensity levels; and an image editing sub-system configured to: edit the image in accordance with a request received from a user by editing pixels in the high dynamic range image data in accordance with the request; and cause the scaled version and its display by the display to be updated with the edits that are made to the high dynamic range image data substantially concurrent with the edits that are made to the high dynamic range image data.
