Impact of Defocusing of the Camera Lens on the Image in Optical Camera Communications [PDF]
, 2018 In this paper, we propose a theoretical model for the intensity of a blurred image of a light source (LS) due to defocusing in optical camera communications. The blurred image is characterized with four parameters of half power full width, maximum intensity, left and right slope of hazy area and we relate them to the LS, channel, and camera settings ...
