Camera sensor enhances automotive and surveillance safety

Melexis announces the launch of the MLX75411 Avocet High Dynamic Range image sensor. Originally designed for automotive driver assistance and night vision applications, this camera sensor chip will also be beneficial for security/surveillance cameras, fleet safety cameras, truck blind spot cameras, transportation/heavy vehicle cameras, and other outdoor and all weather cameras.

The Avocet image sensor is a wide-VGA sensor with a 1024x512 pixels resolution. It features an extended high dynamic range of up to 154dB in every single frame at a full frame speed of 60fps. This offers tremendous picture quality benefits during day time and night time and thus enhances safety offered by driver assistance systems.

Cliff De Locht, product line manager at Melexis comments: “In specific daytime automotive conditions like when sunlight shines directly into the lens, or when driving in or out tunnels or garages, the “Avocet” image sensor is able to give a crisp picture with maximum picture details in the very bright areas of the frame and the dark areas of the frame simultaneously”

“Also for surveillance camera’s the high dynamic range offering is very important. For example day/night surveillance cameras that guard entry doors will want to see a very good exposure of the people’s faces on the inside and on the outside of the door opening simultaneously. Technically speaking, this requires high dynamic range, so the Avocet imager is at its best in these conditions.”
