Claim 28:
29. A system for prediction of ambient light and adjustment of an exposure value of a camera (100) to capture a display of an input image in response to said prediction, the system comprising:
a. the camera (100) capable of capturing images;
b. a display device (200) capable of displaying images; and
c. a computing device (300) communicatively coupled to the camera (100) and the display device (200), comprising a processor capable of executing computer-readable instructions and a memory component comprising computer-readable instructions for:
i. displaying, by the display device (200), one or more reference images;
ii. capturing, by the camera (100), the reference images at one or more camera exposures to generate a plurality of calibration images;
iii. predicting an optimal reference exposure and a corresponding optimal reference image based on a minimal saturation criterion applied to the plurality of calibration images;
iv. estimating the ambient light at the optimal reference exposure;
v. identifying relative properties of an input image in comparison to the optimal reference image;
vi. predicting an optimal exposure based on the relative properties of the input image, the ambient light and the optimal reference exposure; and
vii. adjusting the exposure value of the camera (100) based on the optimal exposure.
