Abstract
A processor calibrates the camera by presenting an input image on the display to obtain a presented image. The camera, arbitrarily positioned relative to the display, records the presented image. The processor obtains the input image via a channel different from the display. The processor obtains an indication of a display region associated with the display. The processor determines an input image region corresponding to the display region, and a recorded image region corresponding to the display region. The processor obtains a first pixel value associated with the input image region and a second pixel value associated with the recorded image region. The processor determines a mapping between the first pixel value and the second pixel value, where applying the mapping to the second pixel value substantially produces the first pixel value. The processor stores an identifier associated with the recorded image region and the mapping.
