Abstract
Methods, systems, and devices are described for processing Visual Light Communication (VLC) signals by identifying a subset of pixel elements likely to receive at least a portion of of detectable light transmitted from one or more VLC light sources, based on a first frame of pixel sample values. One method may include generating a second frame of pixel sample values of VLC signal intensities and limiting processing to the identified subset of the pixel elements.
