    Shanghai, China, December 26, 2024 - Steway (Shanghai) Electronic Technology Co., LTD. (Stock abbreviation: Steway, stock code: 688213) today announced the launch of the SC935HGS(9MP) and SC635HGS(6MP) global shutter image sensors for high-performance Intelligent transportation (ITS) applications. The two new products are based on Steway's advanced SmartGSTM-2 Plus technology and are equipped with Lightbox IR? Nir enhancement technology supports a variety of HDR modes, with high dynamic range, high frame rate, low noise, no distortion and other performance advantages. In view of the actual scenarios of intelligent transportation applications, SC935HGS and SC635HGS carry out comprehensive optimization of several key capabilities such as high temperature performance, frame rate, shutter efficiency, etc., which can effectively solve multiple types of pain points in road monitoring, and fully meet the needs of rapid, clear, accurate and stable image capture of intelligent transportation systems under various complex conditions.

    When shooting high-speed moving objects, the Rolling Shutter image sensor is prone to motion trailing and deformation due to the working principle of line-by-line exposure, resulting in distortion of information acquisition. The SC935HGS and SC635HGS equipped with SmartGSTM-2 Plus technology are used as backlighting Global Shutter image sensors to realize simultaneous exposure of all pixels in the shooting, which can effectively suppress the generation of motion deformation and tailing blur. Therefore, in ITS high-speed traffic flow shooting scene, SC935HGS and SC635HGS can help the camera to achieve clear, accurate and rapid capture without motion distortion, and improve the accuracy of vehicle information acquisition.

High sensitivity, high dynamic range, high quality image capture
    The quality of image acquisition directly affects the discriminant efficiency and accuracy of intelligent transportation system. As an iterative upgrade of intelligent transportation applications, SC935HGS and SC635HGS have significantly improved many key performance such as sensitivity, dynamic range, noise control, and will provide new high-definition images with higher picture quality and better night vision effect for ITS systems.

High sensitivity
    Thanks to Sterway's advanced SmartGSTM-2 Plus technology, the peak quantum efficiency of the SC935HGS and SC635HGS at 520nm visible light band is as high as 78%, which is significantly higher than the previous generation, and can fully guarantee the imaging clarity in low light conditions. In addition, the SC935HGS and SC635HGS are innovated with Stevie's patented Lightbox IR? Near infrared enhancement technology, near infrared band sensitivity is better than the industry competition products of the same specifications, can be applied to overseas near infrared lighting intelligent transportation system equipment, improve the regional compatibility of terminal products.

High dynamic range
    Based on PixGain technology, the SC935HGS and SC635HGS achieve all-weather HD effects without fear of day and night light changes. In low light environment at night, High Gain can be used to reduce the reading noise and make the picture details clearer; In the daytime strong light environment, Low conversion Gain (Low Gain) is used to prevent overexposure of the picture, so that the image is delicate light and shade. Meanwhile, the SC935HGS and SC635HGS support Zone HDR and ColGain HDR? Two single-frame HDR modes can effectively improve the dynamic range, reduce the impact of day and night light changes on the imaging of ITS cameras, and reduce the occurrence of local overexposure or dark detail loss.

Low noise

    The SC935HGS and SC635HGS adopt the advanced Stack MIM capacitor process and the innovative Denoise algorithm, which significantly reduces the image noise from the circuit process and algorithm level. The SC935HGS and SC635HGS have approximately 57% less read noise and 42% less fixed noise than their predecessors. The excellent low noise effect can ensure the texture and clarity of the details of the night image of ITS camera, and improve the accuracy of night information collection.

A number of performance optimizations to create a stable and reliable ITS vision system
    In the practical application of ITS road monitoring camera, it needs to face multiple difficulties and challenges such as outdoor high temperature weather and high-speed vehicle shooting. In view of this, SC935HGS and SC635HGS have optimized the performance of key pain points such as high temperature performance, frame rate and shutter efficiency, which can significantly improve the stability of image capture and create an accurate and reliable ITS vision system.
? High temperature performance optimization
    In high temperature weather, ITS outdoor cameras used in road monitoring and other scenes need to be tested by all-weather sun exposure. The SC935HGS and SC635HGS significantly optimize high temperature imaging performance with advanced SmartGSTM-2 Plus technology and manufacturing processes. Taking SC935HGS as an example, at 80℃ high temperature, Shading is reduced by about 83% compared with the previous generation, which can effectively solve the problem of camera imaging edge purple at high temperature.

Higher frame rate
    According to the application scenario characteristics of ITS high-speed vehicle shooting, SC935HGS and SC635HGS carry out frame rate optimization, which can support the highest 65fps ultra-high frame rate, ensure the fluency of high-speed traffic video shooting, and provide customers with more frame rate redundancy, improve the flexibility of practical applications.

Shutter efficiency optimization

    At present, the SC935HGS and SC635HGS have received samples and are expected to achieve mass production in Q2 2025. For more information about SC935HGS and SC635HGS, please contact our sales staff.
