Sony Semiconductor Solutions Corporation (Sony) has announced the upcoming launch of the IMX828, the industry’s first*1 CMOS image sensor for automotive use featuring a built-in MIPI A-PHY interface. Traditionally, automotive cameras have relied on externally mounted serializer chips to support high-speed transmission interface standards. With the IMX828, this external component is no longer necessary, enabling the development of more compact camera systems with lower power consumption and simplified thermal design.
Delivering an 8-effective-megapixel*2 resolution, the IMX828 achieves the highest*1 level of high dynamic range (HDR) performance in the industry. Enhanced HDR capabilities offer significantly improved recognition of high-luminance objects, such as red LEDs, boosting safety and reliability for automotive applications. The sensor also features a low-power parking surveillance function, enabling motion detection to help deter theft and vandalism.

Sony plans to expand this approach by developing additional products that incorporate high-speed transmission standards beyond MIPI A-PHY, following a flexible, open-standard interface strategy. This commitment underscores Sony’s role in driving innovation in next-generation automotive camera technology.
Additionally, the IMX828 is equipped with Sony’s proprietary error-handling circuitry, enhancing resistance to errors caused by external noise and supporting the high-bandwidth, low-latency, and reliable communications required in modern automotive camera-to-ECU systems.

To support the high-bandwidth, low-latency, and highly reliable communications between the camera and ECU that automotive camera systems require, multiple high-speed transmission interface standards exist. The IMX828 is the industry’s first*1 example of a product equipped with a MIPI A-PHY interface directly built into the image sensor. The new sensor is also equipped with Sony’s proprietary error handling circuit, which makes it highly resistant to errors triggered by external noise when transmitting data.
With these features, the new product offers the following advantages to OEM and Tier 1 partner businesses:
- Reduced cost thanks to eliminating the need for an externally mounted serializer
- Compact board size and suppressed heat generation
- Reduced camera module power consumption
- Improved resistance to errors due to external noise
