Abstract
A method and apparatus for optical field communication, wherein incident light is spread on the surface of an image sensor with a diffuser element; a conventional digital image is captured with high exposure pixel rows of the image sensor; and the light intensity on two successive low exposure pixel rows of the image sensor is recorded. The recorded light intensities of the two successive low exposure pixel rows are compared; and in response to comparing the recorded light intensities of the two successive low exposure pixel rows, a value of a bit received via optical field communication is determined.
