Sony FCB camera block
SONY FCB-EV9520L uses SONY’s latest STARVIS2 CMOS sensor to provide a wide dynamic range that allows it to capture clear, detailed images in complex lighting environments. At the same time, it has also brought substantial applications to more industries.
Wide dynamic definition
Wide Dynamic Range (WDR) is an image processing technology used in cameras to solve the problem of high brightness areas under strongly contrasting lighting conditions, such as strong light sources (daylight, lamps or reflections, etc.), and low relative brightness areas such as shadows and backlights. Problems with degraded image quality or loss of detail from the camera output.
Specifically, wide-motion technology can expand the camera’s ability to adapt to changes in image brightness and color temperature, so that particularly bright and particularly dark parts of the scene can be seen clearly at the same time.
The wide dynamic decibel number (dB) is a commonly used unit of wide dynamic, which represents the logarithmic representation of the ratio between the brightest brightness signal value that an image can resolve and the darkest brightness signal value that can be resolved.
The most common wide dynamic range is between 50 and 70dB, while advanced all-in-one cameras have a wide dynamic range between 100 and 130dB.
Wide dynamic advantage of FCB-EV9520L
1. high and wide dynamic range:
The human eye can recognize the dynamic range is about 120dB, and the SONY FCB-EV9520L’s wide dynamic range is up to 130dB, which means that it can recognize the dynamic range better than the human eye, more effectively processing the scene with strong light contrast, ensuring that the details of the light and dark can be clearly presented.
2. Wide-D mode:
The SONY FCB-EV9520L is equipped with Wide-D mode, an advanced image processing technology that enables the image to be divided into several areas for independent processing. By increasing the brightness of dark areas and decreasing the brightness of bright areas, Wide-D mode can significantly adjust the contrast between light and dark in the image, making the overall picture more balanced and natural.
3. advanced processing technology:
When the Sensor enters the CMOS era, the wide Dynamic Range is also known as HDR, that is, High-Dynamic range. In particular, the film and television industry, the display field, mobile phone screens, photography and videography are generally called HDR.
(1) DOL HDR
When the DOL HDR (Digital Overlap High Dynamic Range) function of SONY FCB-EV9520L is enabled, its image sensor will first take an image with a short exposure time to match the light, and then take an image with a long exposure time to match the dark. They are overlapped to achieve HDR.
This function sometimes causes artifacts such as contour blur or color change in the moving parts when shooting the subject moving at high speed.
(2) Clear HDR
When the Clear HDR function of the FCB-EV9520L is enabled, the image sensor simultaneously takes a low-gain image to match the light and a high-gain image to match the dark, and then performs an overlay synthesis of the image.
Using this method, two images can be obtained at the same time, so even when shooting a high-speed moving subject, the image can be obtained without artifacts such as color difference.
The Clear HDR function is not only suitable for security cameras, but also for applications such as traffic monitoring and dashcams that require high-speed moving subjects to be captured.
SONY FCB-EV9520L is equipped with both DOL HDR and Clear HDR functions to provide clear and delicate images in a variety of more complex lighting conditions, making the FCB-EV9520L has a wide range of application potential.
Application scenario
The SONY FCB-EV9520L’s wide dynamic range of 130dB is well represented in a variety of industries, especially those that need to deal with complex lighting environments to ensure clear image detail and balanced contrast.
Security monitoring:
In the field of security monitoring, the high and wide dynamic range of the FCB-EV9520L enables it to capture clear images in environments where strong sunlight and shadow intersect, such as city streets, squares, etc. Whether it is the bright sunshine area or the details in the shadow, it can be well displayed, improving the effectiveness and accuracy of the monitoring picture.
Intelligent Transportation:
In intelligent transportation systems, the FCB-EV9520L can be used in traffic surveillance cameras to capture vehicles and pedestrians on the road. Its wide dynamic characteristics help in the sunrise and sunset, tunnel entrance and exit of large light changes in the scene, even high-speed cars, FCB-EV9520L Clear HDR function can effectively eliminate possible contour blur or color changes, maintain the clarity and contrast of the image, providing strong support for traffic management and safety.
Industrial inspection:
In the field of industrial inspection, FCB-EV9520L can be used in visual inspection systems on production lines, such as detecting defects and dimensions on product surfaces. The wide dynamic range allows the camera to accurately capture product details in uneven lighting environments, such as backlight, side light, etc., improving the accuracy and efficiency of detection.
Laser gun tree cutting:
The application of FCB-EV9520L in the laser gun tree cutting camera is also extremely important. In the process of laser tree cutting, you may encounter a complex environment of direct sunlight and tree shadows. The wide dynamic range of the FCB-EV9520L automatically adjusts the brightness and contrast of the image, ensuring that clear image details can be captured in both bright and dim areas, thus ensuring the safety and efficiency of the job.
Medical industry:
In the medical field, the FCB-EV9520L can be used for monitoring scenarios such as operating rooms and wards. Its wide dynamic range helps to maintain the clarity and color reproduction of the image in the light and shade contrast between the surgical light and the surrounding environment, providing accurate visual information for medical personnel.
Drones:
In drone applications, the FCB-EV9520L can be used for environment awareness and obstacle detection. The wide dynamic range enables it to maintain a clear perception of the surrounding environment under different lighting conditions, such as sunrise and sunset, cloud cover, etc., improving the safety and reliability of unmanned vehicles and drones.
To sum up, wide motion is a very important and practical image processing technology for cameras, which can provide clear and stable image output under strongly contrasting lighting conditions. SONY FCB-EV9520L’s 130dB wide dynamic range and advanced image processing technology enable it to provide clear and delicate images under a variety of complex lighting conditions, meeting the needs of more industries for high-definition picture quality.
