Video processor brings HD quality to rear-view cameras

July 10, 2017 //By Christoph Hammerschmidt
Better image quality to prevent backover accidents: With this recipe tries Intersil to persuade designers to design its TW8844 LCD video processor into rearview imaging systems. The highly integrated SoC is the first Full HD video processor for automotive applications.

Integrating an analog video decoder, two scalers and a MIPI-CSI2 SoC interface, the TW8844 enables the migration from analog to digital camera systems. It supports a variety of video interfaces and LCD panel resolutions up to full HD 1920 x 1080. The TW8844 LCD video processor is ideal for center stack/head units, full display rearview mirrors, instrument cluster displays, and dual headrest rear-seat entertainment systems.

Automakers are starting to make rearview camera systems standard equipment for all new car models worldwide. In the U.S., the National Highway Traffic Safety Administration mandated in March 2014 that automakers implement "rear visibility technology" as standard equipment for all vehicles under 10,000 pounds, as part of the Kids Transportation Safety Act. The new FMVSS-111 regulation specifies that the area behind a vehicle must be visible to the driver when the vehicle is placed into reverse, thereby minimizing blind spots. The law aims to reduce the number of deaths and injuries caused by driver backup accidents, many involving young children. The FMVSS-111 law requires that all new vehicles sold in the U.S., beginning in May 2018, have rearview backup cameras and the rear camera video must display in less than two seconds after the driver places the vehicle into reverse gear. While in Europe no such law is in place, the demand for rearview cameras is rising, in particular in the upmarket and SUV segments.
