CogniVue, Fraunhofer debut supersmall camera at Electronica
As automotive electronics takes center stage at Electronica this week in Munich, a “microcamera” module recently designed by researchers at the Fraunhofer Institute for driver-assistance applications is expected to enjoy the spotlight.
The Ottawa embedded vision IP vendor CogniVue and Berlin’s Fraunhofer Institute revealed Tuesday that they have collaborated on development of the microcamera. It uses CogniVue’s image processing technology and a Freescale Semiconductor image cognition processor based on CogniVue’s IP.
The new camera module — an image sensor with optics mounted on a printed circuit board — measures 16x16x12 cubic millimeters. It is visibly smaller than current-generation driver-assist cameras, whose edge lengths are “20x20x20 cubic millimeters (without optics),” according to a Fraunhofer press release.
Clearly, the German institute’s assembly and interconnection technology played an integral role in winning the size battle. However, size isn’t the only prerequisite in meeting the automotive industry’s growing demands for Advanced Driver Assistance System (ADAS) cameras. Others include accuracy, speed, power consumption, and cost, Tom Wilson, vice president of product management at CogniVue, told us recently.
The trend among Tier 1s and carmakers designing ADAS cameras is to use a camera module already integrated with an image processing core. Rather than sending captured images to a chip located elsewhere for processing, they prefer a camera module with “a purpose-built processor for running embedded image and vision algorithms,” Wilson said.
