OmniVision Technologies will be showing an automotive camera module at the AutoSens conference in Brussels from 17 to 19 September, built using OmniVision’s OX03A1Y image sensor with an Arm Mali-C71 image signal processor.
OmniVision and Arm used an FPGA emulating the Mali-C71 ISP to simultaneously process images captured by the OX03A1Y sensor for both computer vision and human displays. This sensor uses an RCCB clear colour filter pattern to capture high quality images in all lighting conditions.
The Mali-C71 then processes the data concurrently, outputting two simultaneous image signals for both human viewing and machine vision.
The OX03A1Y has a 3.2µm pixel with a dynamic range of 120dB, dual conversion gain for motion artefact-free HDR to 85dB, and an RCCB colour filter. The RCCB colour filter allows in more light for low-light performance.
Tom Conway, director of product management, automotive and IoT at Arm, said: ‘OmniVision’s dual-mode image sensor showcases the Mali-C71’s ability to process multiple real-time inputs with one pipeline, capturing both human display and computer vision images with a single image sensor, at the highest possible quality.’
‘Arm’s ISP intellectual property is an important part of the automotive ecosystem, and they are a key partner for OmniVision,’ said Celine Baron, staff automotive product marketing manager at OmniVision. ‘This collaboration demonstrates the high performance that can be achieved by combining our premium 2.5MP image sensor with Arm’s ISP, for automotive applications that need both computer vision and human displays from a single camera module.’
