Abstract
A camera creates successive digital images of a scene, and computes a stability measure estimate blur in a final photograph of the scene. The camera combines information such as lens focal length, focus distance, scene brightness value, and shutter speed to determine alternate camera settings that may reduce the blur. The camera communicates to the photographer suggested camera setting changes that may reduce the blur. The communication may optionally happen before the final photograph is taken or after, and may take one of several forms. The camera may optionally be a digital camera. The setting change suggestions may optionally be stored in an image file with a final digital photograph.
