Renesas Electronics and its subsidiary, Renesas Mobile Corporation, a supplier of cellular semiconductor solutions and platforms, have made available their new image recognition system-on-chip (SoC), the SH7766. This device integrates on a single chip all the functions required for the implementation of camera-based surround view systems together with the display of crucial information such as signs, markings, pedestrians and vehicles.
The SoC retains compatibility with Renesas’ existing SH77650 image recognition SoC while delivering improved performance. In particular, the display functions such as viewpoint conversion and dynamic range control (brightness compensation, etc.) have been enhanced making it possible to develop applications with clear top-view virtual camera visualization. These can use different viewpoints to display the changing surroundings in real time and provide monitoring functionalities such as advanced driver assistance systems (ADAS).
ADAS applications, such as lane deviation warning systems are becoming more widespread. Related trends include display applications that enable drivers to monitor their vehicle’s surroundings while parking. These applications include rear-view monitor and top view systems which are gaining in popularity. Advances have been made in seamless safety support systems that provide uninterrupted coverage of the area in front of the vehicle as well as its surroundings. For this reason, there is growing demand for improved image recognition technology, to underpin sensing and extended functions that provide a clear and easily understandable display to the driver.
At the same time, image recognition systems are diversifying beyond lane recognition to include simultaneous recognition of multiple objects such as signs and markings, pedestrians, and vehicles. This has led to a demand for increased performance in image recognition engines, which must perform multiple processing tasks in parallel. An efficient architecture using a combination of CPU and specialized IP is necessary to handle the different recognition algorithms in order to distinguish objects of different shapes and sizes as well as people.
In response to these demands, Renesas' next-generation SH7766 image recognition SoC improves on the performance of its predecessor, the SH77650, and delivers enhanced view functions and higher image recognition engine performance.
