Fluorescent lamps are becoming popular as an indoor light source in many commercial sites. While high speed video cameras can detect variations in the illumination levels from such light sources, they can be quite costly to operate. Moreover, most popular security video cameras can only operate up to a maximum speed of 30 frames per second. Would the camera be able to detect such variations in the scene caused by the inconsistent level of illumination from the fluorescent lamps? This paper examines several image quality measures to detect flickering on video signals from the video cameras at low frame rates. Future research is outlined at the end of the paper.
