Phase-Detection Autofocus Delivers Fast and Superior Object Detection and Recognition for 4K Video Security and Surveillance Applications
Renesas Electronics Corporation introduced an ultra-high-definition (UHD) surveillance camera reference design to address today’s high-accuracy object detection and recognition needs for video security and surveillance systems. Developed in collaboration with Novatek Microelectronics Corporation and designed by Systemtec Corporation Ltd, the reference design includes a camera image sensor (CIS) board with phase-detection autofocus (PDAF), and a high-performance image signal processing (ISP) board along with auto focus zoom lens software.
The surveillance camera reference design enables 4K resolution, excellent color imaging and better recognition accuracy of objects, including small objects in low-light conditions. Its impressive high-speed autofocus operation can also be realized with low-priced lenses. This features combination allows Systemtec to offer customers a high-performance 4K video security camera reference design and software that helps shorten their development time building a camera system with fast autofocus and enhanced imaging performance.
Built around Renesas’ high performance RAA462113FYL CMOS image sensor and Novatek’s dual core SoC image signal processor, the surveillance camera reference design uses several other Renesas ICs that address its signal chain electrical functions. The CIS board includes the RAA462113FYL, DC/DC buck converters, LDOs, motor driver and lens. The ISP board features the SoC and associated signal chain components.
