Stewell (Shanghai) Electronic Technology Co., Ltd. (stock abbreviation: Steway, stock code: 688213), a heavy launch of 2.3MP Sensor+ISP two -in -one car -level image sensor new products -SC233AT.This back -illuminated global shutter image sensor integrates high sensitivity, high dynamic range and excellent film processing capabilities. It can empower the driver monitoring system (DMS), passenger monitoring system (OMS) and other cabins with excellent image quality.Imaging application.
With the intelligent acceleration of the car, the car camera has begun to be widely used in the inside of DMS/OMS. The autonomous driving industry has entered a period of high -quality development, which has also driven the large improvement of the market size of the car CMOS image sensor.According to YOLE forecast, the global car CIS market size in 2027 will reach US $ 3.244 billion, of which the CIS market size used in the cabin imaging system will grow from US $ 209 million in 2021 to US $ 571 million in 2027, and its development space is very broad.
The new product is the first car image sensor equipped with the new Lightbox IR technology, which can achieve clearer near -infrared imaging. It can also provide accurate image information for the DMS/OMS system in a dark light environment.SC233AT uses SmartGS-2 global shutter technology. Relying on advanced SFCPixel and single-frame turning point HDR technology, even if the low light or light conditions are strongly changed, it can provide clear high-quality imaging.As a new masterpiece of Steomotive Sensor (at) Series series, SC233AT complies with AEC-Q100 Grade 2 and functional security ISO 26262 ASIL B level requirements to promote the development of smart cockpit applications with high performance and high security and reliability.
The new Lightbox IR technology blessing, enhance the sensitivity of near infrared
With the increasing importance to the public on driving safety, in order to further improve the safety of drivers and passengers in the rear seats, the DMS and OMS systems have emerged and the assembly rate has continued to increase.
Near -infrared sensitivity is a key parameter that guarantees the image sensitivity and sharpness of the DMS/OMS system.Stewell's advanced LightBox IR? Technology can effectively improve the image sensor near infrared sensitivity. By introducing improved deep groove isolation (DTI)Crosstalk can obtain clear drivers and in -cabin images in the environmental environment to ensure the accuracy of artificial intelligence training and algorithm recognition.
In addition, the SC233AT is based on the SmartGS-2 global shutter technology, and relying on the unique SFCPixel patented technology of Stewell, it can achieve high recognition accuracy and no delayed imaging.The state and eyes state, thereby greatly improving the monitoring effect of the DMS/OMS system.
On the other hand, relying on the ultra-low noise peripheral reading circuit technology of Steway, SC233AT brings lower read noise and the unevenness of pixel response (PRNU), which are reduced to 2.85E-and 0.66%, respectively.Make the imaging screen cleaner and clear.
Sensor+ISP two -in -one, creating excellent image quality
The SC233AT image sensor that integrates ISP function can effectively improve the quality and enhance details.Through advanced functions such as automatic gain control (AGC), automatic exposure control (AEC), noise reduction, edge enhancement, etc.Smart cockpit system's high -precision demand for images.
In addition, the DMS/OMS system will encounter a lot of special scenes when running, such as the strong light that is easy to appear when the light is smooth, and the dark picture that is easily caused by the backlight.Inhibit the strong light, so that in the scene where light changes are changing, clear images can still be taken, and the ability to respond to complex traffic scenarios for smart cockpit systems.
Global shutter architecture under the single -frame turning point HDR technology to achieve high dynamic range
Even if the camera is in the car, the image quality will be disturbed by external light.Extreme light conditions also challenge the DMS/OMS imaging system.Therefore, the CMOS image sensor equipped with HDR function has received widespread attention.
Different from the traditional HDR synthesis method, the SC233AT uses a unique single -frame turning point HDR technology. Through a special pixel timing control method, it expands the dynamic range and achieves non -linear light response.Dynamic range imaging (dynamic range can reach 91.5dB).The SC233AT can present rich bright and dark details in the scene with a large and dark contrast, helping the DMS/OMS system to capture the facial, eye -catching status or movement characteristics of drivers and passengers in the DMS/OMS system.Function.
Mr. Shao Ke, vice president of Stewell Automotive Chip Department, said: With the rapid improvement of the DMS/OMS system, the automotive intelligent industry has gradually entered the critical period of moving towards higher -level autonomous driving.Stewell 2.3MP car regulations ISP two -in -one image sensor New product SC233AT starts from customer needs, with both high dynamic range, excellent near -infrared imaging technology and back -photo global shutter technology.Provide car customers with visual solutions in the cabin.In addition, in terms of vehicle regulation safety, SC233AT complies with AEC-Q100 Grade 2 and ISO 26262 ASIL B functional security level requirements. It can be used for smart cockpit monitoring systems such as DMS/OMS to ensure driving safety with safe and reliable vehicle-level quality.Help promote higher -level autonomous driving.
Stewell has released 10 car -level image sensor products, covering 1MP ~ 8MP resolution car perception and image segmentation application needs.In the future, Stewell will continue to focus on the three application scenarios of car image, perception and inside the cabin, and further enrich the AT Series series product matrix. Under the strict automotive product development process system, rely on its core technology and product performance advantages to promote the advantages of its own core technology and product performance, promote itThe intelligent development of automobiles and the penetration and popularization of intelligent driving technology.
SC233AT provides two versions of black and white and RGB-IR. It has been sent samples and is expected to achieve mass production in Q2 2023.If you want to know more about SC233AT, please contact Stewell sales staff.
