Introduction
In recent years, cross-border car manufacturing, new energy vehicles, and autonomous driving technology have become buzzwords in the business. The rapid rise of the automotive industry and the upgrade of autonomous driving technology have contributed to the expansion of market demand for automotive cameras. With policy guidance, the implementation of advanced autonomous driving technologies can be accelerated. The automotive camera market is expected to surpass the mobile camera market in size.
Viewing the overall car camera market, we can find that the camera categories are relatively concentrated, and horizontal development is the top priority. In the context of the explosive market demand for automotive cameras and the upgrading of autonomous driving technology, the automotive surround-view camera is expected to become a breakthrough in creating a larger market scale.
Yole expects that in the L3 model, a car will use seven cameras, including two front view cameras, one other camera, and four surround view cameras. Surround-view cameras have the highest percentage of bike cameras.
The surround view system usually includes four ultra-wide-angle cameras in four directions in the front and rear of the vehicle to collect environmental information around the vehicle. Through image distortion correction and panoramic stitching, it can restore the 360° real scene of the vehicle and eliminate visual blind spots. The advantages include automatic assist driving, parking, and car usage scenarios to reduce collisions, scratches, and other accidents. Currently, surround-view cameras are used in first-tier car brands such as Willey, Mercedes-Benz, BMW, and Lexus.
As the cornerstone of the development of surround-view cameras, the image sensor's performance directly affects the image quality captured by the camera. To meet the application requirements of automotive surround view cameras, leading image sensor companies such as ON Semiconductor, OmniVision, and Stevie have launched 360° surround view image sensors to meet vehicle standard applications and assist the development of advanced intelligent assisted driving.
The rapid introduction of automatic-assisted driving technology in the application of new energy vehicles has become the selling point of many new energy vehicles, including the domestic company of Lixiang ONE. The Lixiang ONE model is equipped with L2 automatic assisted driving system technology development, and the Lixiang ONE intelligent driving-assistance system vision solution focuses on the development of image sensors.

OmniVision has a complete technical reserve and industrial layout in the field of automotive image sensors and has launched a vision solution suitable for autonomous driving applications, which has been verified and mass-produced in many first-tier brand models. In the Lixiang ONE autonomous-driving vision solution, there are six OmniVision image sensors, including five OV10640 image sensors and an OV10642 image sensor, of which four OV10640 image sensors are used to build a 360° surround view system.
OV10640 is an image sensor specially launched by OmniVision for 360° surround view applications, dedicated to bringing clearer visual images to the new generation of autonomous driving assistance systems. The OV10640 is an image sensor with a density of 1.3 million pixels, capable of capturing 60 frames per second.
At the same time, in order to improve the final imaging effect, OmniVision has added a unique HDR processing technology to the sensor, which enables the sensor to output high-definition images in a wide dynamic range of 120dB to reduce the artifacts caused by the rapid movement of the vehicle. In the Lixiang ONE’s 360° surround view system, the 360° surround view images around the vehicle body are seamlessly stitched through four cameras. The cameras improve the route perception and environment perception of the automatic driving assistance system, realizing the Lixiang ONE route departure warning and automatic parking functions.

In the field of automotive image sensors, ON Semiconductor started a little earlier than first-tier manufacturers such as OmniVision and Stevie and has accumulated certain development experience in this field and is in a leading position in the industry. According to previously announced data, ON Semiconductor's image sensor shipments in the global automotive perception field remained above 80% throughout the year, slightly lower in the automotive imaging field with a market share of 60%. ON Semiconductor is the largest supplier in the field of the automotive image sensor.

With the popularization of automatic assisted driving technology, in-vehicle cameras are developing towards higher pixels. Last July, ON Semiconductor released the AR0820AT, which is an 8.3-megapixel digital image sensor. It is adopted by Autox for the construction of 360° surround view perception of the fifth-generation unmanned driving system, enabling L4-level autonomous driving capabilities.
AR0820AT is a 1/2-inch automotive-grade image sensor with flexible exposure ratio control and HDR reconstruction to capture closer to actual color and brightness in high dynamic application scenarios. It can maintain high performance and improve the perception accuracy of the image sensor even in low-light applications.
The pixel density of the image sensor is 3848H*2168V. The image sensor supports fast full-resolution image capture at 40fps. Meanwhile, it can also increase the actual sensing distance by 300 meters to ensure that the driver can identify the information of pedestrians, vehicles, and road signs. Furthermore, it allows drivers to have enough reaction time when driving at high speed.
According to ON Semiconductor, image sensors can be used in ADAS front-view cameras, surround-sensing cameras, and automotive surveillance cameras.
Conclusion
The 360° Surround View system plays a powerful auxiliary role in eliminating blind spots and improving car safety. With the rapid development of the automotive industry and autonomous driving technology, it is expected that the market size of the automotive camera industry will continuously enlarge, which accelerates the promotion and iteration of image sensor products.
