As a technology innovation company dedicated to imaging and vision technologies, we recently launched an ultra-small automotive surround view camera module based on ON Semiconductor's 3-megapixel AR0341AT image sensor. This module helps improve driving safety metrics, effectively addresses the demand for excellent HDR performance and image quality in high-speed autonomous driving, and reduces system development costs.

ON Semiconductor Ultra-Small AR0341AT Image Sensor

The AR0341AT is among the first products in ON Semiconductor's new Hyperlux image sensor series. It is equipped with second-generation Super Exposure pixel technology, featuring industry-leading 150 dB High Dynamic Range (HDR) and LED Flicker Mitigation (LFM) capabilities. This pixel technology eliminates the need for automatic exposure control operations, significantly reducing latency in critical automotive systems that rely on scene information, thereby enabling faster and safer data collection and decision-making.

Without compromising performance, this 3-megapixel AR0341AT image sensor, with its 2.1 µm pixel size, becomes the industry's smallest automotive camera thanks to its small optical format and industry-leading low power consumption. Additionally, the AR0341AT image sensor is designed following an ASIL-C design process, and its sophisticated real-time safety mechanisms and fault detection capabilities exceed ASIL-B hardware metrics.

Exceptional HDR Performance

The AR0341AT image sensor boasts a 150 dB High Dynamic Range (HDR), enabling it to capture high-quality images under the most extreme lighting conditions without sacrificing low-light sensitivity. As one of the first products to utilize Hyperlux technology, the AR0341AT, with its exceptional HDR performance, delivers vivid, sharp, and detailed images. Its extreme stability and immunity to changes in temperature or lighting conditions lay the foundation for higher safety designs.

As shown in the figure below, Hyperlux sensors perform exceptionally well in the most demanding and extreme environments.

Real-Time Functional Safety Mechanisms

The Hyperlux design of the AR0341AT image sensor meets the stringent safety requirements of Automotive Safety Integrity Level D (ASIL D) systems, and its integrated security provides maximum protection against cybersecurity threats. Hyperlux series sensors also offer dual output streams at different resolutions, allowing for simultaneous execution of perception and other functions. Designers can benefit from its flexible architecture to achieve multiple functions with a single camera, thereby reducing design time, risk, and cost.

Xinmai Ultra-Small 3-Megapixel Automotive Surround View Camera

Leveraging its full-stack technical capabilities in high-quality imaging and extensive mass production experience, combined with the company's industry advantages in intelligent driving and perception imaging, it has successfully developed a camera module product based on ON Semiconductor's 3-megapixel AR0341AT sensor: SG3-AR0341C-G2F-H190X.

This camera module, based on the AR0341AT image sensor, features a 1/3.6-inch sensor area and 2.1µm pixel size, capable of achieving 150dB High Dynamic Range, supporting 1920H*1536V resolution and 3-megapixel high pixel count. This means the camera can capture vivid, detailed, high-quality images, and performs exceptionally well in low-light conditions, overall Signal-to-Noise Ratio (SNRs), and HDR. It effectively meets the demand for stable and high-quality images from cameras in the most demanding and extreme environments.

The camera module boasts a wide 190° horizontal field of view, making it widely applicable in autonomous parking scenarios requiring ultra-wide-angle surround view functionality, providing precise image perception solutions for intelligent parking space recognition and parking path planning.

In terms of appearance, this camera module has an overall size of only 24mm24mm16.5mm and weighs approximately 50g. Its ultra-small form factor makes it easy to install. The product meets automotive-grade protection levels and is particularly suitable for applications such as in-vehicle vision, Advanced Driver-Assistance Systems (ADAS) and vision fusion, high-dynamic applications, autonomous driving, and robotics.

This ultra-small, high-performance camera module enables customers to achieve highly energy-efficient designs with lower system material costs and a more flexible architecture. Furthermore, to meet a wider range of customer needs, a series of camera products compatible with various serializer solutions and interface protocols have been launched. Serializer solutions from TI, Renxin, and Ruifake, among others, will also be successively introduced.

AR0341AT Camera Solution Based on Mainstream Platforms

The 3-megapixel AR0341AT automotive surround view camera module also supports mainstream platforms such as NVIDIA, Qualcomm, and TI. It can provide customers with camera solutions based on official kits, as well as professional ISP tuning services.

As an NVIDIA partner, relying on software driver technology on DRIVE AGX Orin and Jetson AGX Orin, this innovative 3-megapixel AR0341AT automotive surround view camera module has been deeply integrated and successfully adapted to both the DRIVE AGX Orin and Jetson AGX Orin platforms. This will enable more developers to more efficiently develop various applications tailored to their needs, as well as conduct learning and research.

Based on the DRIVE AGX Orin development platform, it will not only provide developers of autonomous vehicles with rich and mature 3-megapixel AR0341AT surround view automotive camera module products but also offer camera drivers to support test environment setup, and a team available for ISP tuning services on NVIDIA platforms, allowing developers to use this development and evaluation kit more simply and efficiently.
