Benefits of High Dynamic Range

The Avocet image sensor is a wide-VGA sensor with a 1024×512 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.

"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."

Kids Transportation Safety Act (U.S.)

Although the "Avocet" image sensor was originally designed for automotive front-view applications, the current demand for higher quality rear-view and surround view systems will also benefit from this high dynamic range. We refer to the recently proposed NHTSA rule based on the "Cameron Gulbransen Kids Transportation Safety Act". This rule mandates the timeline for adding rearview cameras in automobiles sold in the US beginning in 2012.

Total Cost of Ownership

The development of the "Avocet" image sensor aims not only at offering a high quality imager at a competitive price, it also targets lowering our customer’s total cost of ownership.

The Avocet’s unique Glass-BGA package features an optical area fully shielded against contamination, moisture (Moisture Sensitivity Level – MSL1) and potentially lowers active lens focus costs by providing very high x,y,z and rotation accuracies by construction.

Samples

The MLX75411 "Avocet" image sensor is available in 4 versions: monochrome, color RGBG, color RGBi and RCCC.
