Abstract
Described are systems and methods to reduce image flickering of a webcam of an information handling system. The webcam includes a photochromic lens that changes translucency based on UV radiation that is received. Image flickering can be caused when high UV radiation from a strong light source is observed. In passive method, the photochromic lens darkens as high UV radiation is received, and light received by the sensor of the webcam is reduced, which leads to lower shutter speed that reduces image flicker. In active methods, the image signal processor or an application is used to detect image flicker. UV emitters included in the webcam provide the UV radiation to cause the photochromic lens to darken.
