A camera in an embedded system is normally connected to an ISP (image signal processing) block inside an SoC to handle the data coming from the sensor, and with recent cars now requiring more and more cameras for car DVRs, car parking systems, and self-driving vehicles, ARM has now unveiled Mali-C71 ISP specifically designed for automotive applications with support for 4 real-time cameras and 16 camera streams with a single pipeline.
ARM explains that you can’t simply use smartphone cameras in automobile, as automotive requirements in terms of clarity and reliability are much more stringent. For example, Mali-C71 supports UWDR (Ultra-wide dynamic range) up to 24 stops, against 15 stops for the best DSLR cameras, which removes noise and process multiple exposures from the camera, and allows the processor/computer vision engine to detect objects such as a pedestrian, while others systems may not detect it. The image is also much clearer to the driver when displayed on a rearview mirror or other displays.
Mali-C71 also brings low latency and advanced error detection with more than 300 dedicated fault detection circuits to complies with automotive standards such as ISO26262, ASIL D and IEC 61508, SIL3.
