Abstract
A method for correcting for exposure in a digital image, captured by an image capture device, including rendering such captured digital image suitable for display and displaying such captured digital image as a first displayed digital image; and using an adjustable exposure setting to nonlinearly modify the rendered captured digital image to effect an exposure change and displaying the exposure modified rendered captured digital image as a second digital image simultaneous with the first displayed digital image.
Claims29
A digital image system for changing exposure in a digital image having an exposure level and for causing a printer to produce a print, comprising:
- means for storing a plurality of rendered digital images;
- means for selecting one of such rendered digital images, and displaying such digital image;
- adjustable exposure setting means for modifying the selected rendered digital image using an exposure modification curve selected responsive to a single user adjustable exposure setting with the exposure modification curve having a curve shape that effectively converts rendered code values back to scene values, adjusts an exposure of the scene values and renders corrected scene values to effect a change which accounts for the rendering and appears as if a different exposure level was used by an image capture device to capture the image and displaying the exposure modified rendered digital image;
- means for tone scale adjusting the modified rendered digital image;
