Patent Images
1. A method for providing anti-glare exposures for an imaging device comprising:
- determining an autofocus distance to an object of interest;
estimating a distance to a flash reflecting surface;
determining the flash reflecting surface is between the imaging device and the object of interest based on a comparison of the autofocus distance and the distance to the flash reflecting surface; and
disabling a flash of the imaging device during an exposure of the object of interest based on the determination the flash reflecting surface is between the imaging device and the object of interest.

Abstract
Techniques related to anti-glare exposures for imaging devices and, in particular, for exposures that disable a flash when a flash reflecting surface is detected between the imaging device and an object of interest of the exposure are discussed. Such techniques may include determining a flash reflecting surface is between the imaging device and the object of interest based on a comparison of an autofocus distance to the object of interest and an estimated distance to the flash reflecting surface and disabling the flash based on the determination.

21. At least one non-transitory machine readable medium comprising a plurality of instructions that in response to being executed on an imaging device, cause the imaging device to provide anti-glare exposures by:
-
determining an autofocus distance to an object of interest; estimating a distance to a flash reflecting surface; determining the flash reflecting surface is between the imaging device and the object of interest based on a comparison of the autofocus distance and the distance to the flash reflecting surface; and disabling a flash of the imaging device during an exposure of the object of interest based on the determination the flash reflecting surface is between the imaging device and the object of interest. - View Dependent Claims (22, 23, 24, 25)
