Camera shake warning and feedback system that teaches the photographer
First Claim
1. A method of improving image blur, comprising the steps of:
- a) computing a stability measure from digital image data;
b) comparing the stability measure with a predetermined value; and
c) selecting a message based on photographic parameters when comparing the stability measure with the predetermined value indicates that blur may occur.

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.

20. A camera, comprising:
-
a) an electronic array light sensor; and
b) a logic unit that controls and receives data from the electronic array light sensor, the logic unit programmed to perform the following method;
i. computing a stability measure from digital image data;
ii. comparing the stability measure with a predetermined value; and
iii. selecting a message based on photographic parameters when the stability measure exceeds the predetermined value. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A system, comprising:
-
a) a camera that computes a stability measure, selects a message based on the stability measure and photographic parameters, and associates the message with an image file; and
b) a computer;
and wherein the image file and associated message are transferred from the camera to the computer and the message is displayed on the computer. - View Dependent Claims (32, 33, 34)
