Described are an optical sensor and method for receiving communications data in an image. The sensor includes a plurality of pixels. Each pixel includes an optical detector for receiving light in a portion of an image and generating an electrical signal in response to the light. The sensor also included a data communications signal detector in communication with the optical detector to detect communications data in the electrical signal. The data communications signal detector includes a data threshold module for detecting a communications bit when the electrical signal exceeds a threshold value.
