Overview

With security systems becoming more popular, IP cameras are now a huge market. Traditional IP cameras are fixed focus or contrast-detection autofocus (AF). As face recognition technology is becoming more of a trend in these systems, 4K ultra-high-definition (UHD) and fast AF are also becoming required features.

In this reference design, Renesas provides a CMOS sensor with phase-detection autofocus (PDAF) functions. PDAF is much faster than conventional contrast-detection AF because of direct focusing. Customers can use low-end lenses because PDAF CMOS interface sensors (CIS) do not require wobbling operation on the lens.

This high performance power and analog system utilizes Renesas PMICs, DC/DC, and LDOs for IP camera modules.

System Benefits:

  • High performance CMOS with PDAF: 8M pixels for UHD, 1/1.9” optical format, 1.85μm x 1.85μm unit cell size
  • High performance PMICs, DC/DC, and LDOs for an integrated solution

Renesas' Lab on the Cloud is an online environment where Renesas solutions, including popular evaluation boards, winning combinations and software, are hosted in a remote lab that customers access and test online.

Surveillance Camera with CMOS Sensor

The surveillance camera module includes a CMOS 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. This 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. 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.
