Sony Unveils Revolutionary CMOS Image Sensor for Automotive Cameras

Sony Semiconductor Solutions Corporation has made a significant leap in automotive technology with the announcement of the IMX828, marking the launch of the industry's first CMOS image sensor equipped with a built-in MIPI A-PHY interface. This groundbreaking innovation is set to improve the efficacy and efficiency of camera systems in vehicles.

A Game-Changer for Automotive Applications

The IMX828 stands out with an effective resolution of 8 megapixels and tailored capabilities for high dynamic range (HDR) imaging. This sensor does away with the necessity for externally mounted serializer chips previously needed for high-speed transmission interfaces. As a result, the design is more compact, less power-hungry, and aligns better with modern thermal management needs in automotive systems. One of the standout features of the IMX828 is its ability to enhance the recognition of high-luminance objects such as red traffic lights or LED indicators, even under bright daylight conditions, substantially lowering the chances of false positives in detections.

Enhanced Surveillance Features

This innovative sensor is not just about clarity and detail; it comes with a low-power, built-in surveillance functionality for parking scenarios. This function allows the IMX828 to monitor surroundings while consuming minimal power, thus safeguarding vehicles against theft and vandalism. When the vehicle is parked, it can detect movement and alert the onboard Electronic Control Unit (ECU) without stressing vehicle energy resources.

Future-Proofing Automotive Safety

Sony's vision for the IMX828 extends beyond its current capabilities. The company is exploring additional high-speed transmission standards beyond MIPI A-PHY to further advance automotive camera technology. Their commitment to a flexible and open-standard interface strategy promises ongoing enhancements in the next generation of automotive applications.

Technical Specifications

1. Model Name: IMX828
2. Effective Pixels: 3848 × 2168 (approx. 8.34 megapixels)
3. Image Size: 9.28 mm diagonal (1/1.7 type)
4. Dynamic Range: Up to 150 dB, offering high performance even in extreme environments
5. Power Supply Requirements: Analog: 3.3V, Digital: 1.1V, Interface: MIPI D-PHY + I2C or MIPI A-PHY

These features denote a significant improvement in quality standards for automotive applications. The IMX828 aims to fulfill AEC-Q100 automotive reliability testing standards, ensuring that it meets both functional safety (ISO 26262) and cybersecurity standards (ISO/SAE 21434).

Conclusion

Set to be available in November 2025, the IMX828 is not just another sensor; it's a pivotal innovation that could redefine the landscape of automotive imaging technology. With Sony leading the charge, OEMs and Tier 1 partners can anticipate reduced costs, streamlined designs, and enhanced functionalities in their automotive camera systems. As vehicles evolve to become increasingly automated, technologies like the IMX828 will be crucial in ensuring safety and reliability on the road.
