Claim 27:
28. A method for prediction of ambient light and adjustment of an exposure value of a camera (100) in order to capture a display of an input image, in response to said prediction, the method comprising:
a. displaying, by a display device (200), one or more reference images;
b. capturing, by the camera (100), the one or more reference images at one or more camera exposures to generate a plurality of calibration images;
c. predicting an optimal reference exposure and a corresponding optimal reference image based on a minimal saturation criterion applied to the plurality of calibration images;
d. estimating the ambient light at the optimal reference exposure;
e. identifying relative properties of an input image in comparison to the optimal reference image;
f. predicting an optimal exposure based on the relative properties of the input image, the ambient light and the optimal reference exposure; and
g. adjusting the exposure value of the camera (100) based on the optimal exposure.
