ARM shapes image processing IP for automotive multi-camera apps
The Mali-C71 processes the multiple exposures from the camera, stitches them together to create an ultra WDR frame, processes the frame at high precision and then then sends it across to a display or a computer vision engine following appropriate dynamic range compression. It also brings low latency, advanced error detection with more than 300 dedicated fault detection circuits, and system-level certification to the highest automotive standards.
Mali-C71 is the first product in the Mali Camera series of Image Signal Processors (ISP) from ARM’s Imaging & Vision Group. It supports the requirements of SIL3 and ASIL-D functional safety for a variety of automotive applications from all-round vehicle awareness, mirror replacement, through to night vision improvement.
Mali-C71 is able to process up to four real-time cameras and 16 camera streams with a single pipeline; it is capable of handling 24 stops of dynamic range to capture every detail from bright sunlight to deep shadows. This enables capture of twice the dynamic range of a standard single exposure sensor and in some cases even outperforming the human eye. There is independent dynamic range management for optimum human vision (display) and for computer vision applications. The IP detects and corrects faults caused by the image, sensor or system to ensure reliability and consistency across every pixel.
