Pixim Enhanced Flicker Reduction
Energy efficiency concerns are leading to large-scale replacement of incandescent lights with fluorescent and LED light sources worldwide. Unfortunately, however, CCD video security cameras suffer from persistent technical issues in the presence of fluorescent and LED lighting that affect the cameras' accuracy and usability. The video sampling issues range from an annoyance to a serious security hindrance.
Pixim has introduced the industry's first real solution for these fluorescent- and LED-related video capture problems. Pixim now offers firmware for its chipsets that includes an Enhanced Flicker Reduction (EFR) mode, which solves the problem while also maintaining Pixim-powered cameras' wide dynamic range: the ability to capture accurate, true-color images in both light and dark lighting conditions, simultaneously.
The video sampling issues that EFR overcomes – fluorescent light flicker, fluorescent color roll, and frequency-modulated LED "blackout" – all are caused by differences between the video field capture frequency (which is set by global standards bodies) and the local AC power frequency (which varies by geographic location). Fluorescent light flicker is a real problem in eastern Japan, Chile and some other Latin American, Caribbean, and Pacific nations. Fluorescent color roll and frequency-modulated LED "blackout" are worldwide problems affecting North and Central America, western Japan, other Asian countries, and most of South America, the Caribbean, and the Pacific.
