Abstract
Techniques are generally described for an image capture system that may include an image sensor, a flash for providing illumination, a data storage, and a processor operatively associated with the data storage. The processor may be adapted to execute computer implemented instructions to pre-store one or more image capture device characteristics in the data storage, acquire data in a pre-capture phase, model shadow effects based on either or both of the pre-stored data and the acquired data, modify one or more image capture device settings based on the modeled shadow effects, and record image data with the image sensor. Illumination may be provided substantially coincident with recording of the image data.
