Sony FCB camera block
In numerous professional scenarios such as industrial inspection, security monitoring, and medical surgery, overly strong light is often an “invisible killer” of image quality. In a backlit environment, partial overexposure and loss of details in the picture not only affect observation but also may lead to the omission of key information.
For strong light environments, Xuanzhan Technology, the official authorized dealer of SONY (China), recommends the SONY FCB-ER9500 4K ultra-high-definition camera module. Its advanced wide dynamic range technology and strong light suppression capability can effectively solve the imaging problems in complex lighting conditions.
I. Imaging Challenges in Strong Light Environments
In practical applications, lighting conditions are often difficult to control. For instance, the high-contrast scene formed by the strong light under the surgical shadowless lamp and the shadow of the tissue can easily lead to local overexposure or underexposure of the picture, affecting the doctor’s observation of the surgical field.
Similarly, in outdoor security monitoring, license plates illuminated by headlights at night often fail to be recognized due to excessive reflection. In industrial inspection, the high light reflection of metal parts can also mask the minor flaws on the product surface.
When traditional cameras deal with these high-contrast scenes, they often find it difficult to simultaneously retain the details of both the bright and dark areas, resulting in a decline in image quality and the loss of key information.
Ii. Strong Light Suppression Technology: From Passive Response to Active Optimization
1. High dynamic range and wide dynamic range, fearless of extreme light contrast
The 1/1.8-inch STARVIS 2 CMOS sensor equipped in the SONY FCB-ER9500, through the Wide-D mode, is a function that divides the image into several blocks to correct shadows and highlights based on brightness differences. Even when capturing targets with backlighting or a wide range of brightness including extremely bright areas, it can achieve image recognition acquisition from dark to bright.
Backlit scene: In the operating room, even when the shadowless lamp is directly exposed to the lens, the module can still clearly present the metal texture and tissue details of the surgical instruments, avoiding the difficulty in identifying blood vessels caused by overexposure.
Night monitoring: In the intelligent transportation scenario, in the face of the extreme contrast between the strong light of vehicle headlights and the dark road surface, the module can simultaneously capture the reflection of license plates and road markings, ensuring the accuracy of night violation capture.
2. Intelligent high-brightness spot suppression, precisely eliminating light spot interference
The suppression of strong light in traditional cameras is often achieved by globally reducing the exposure, but it can easily lead to an overall dark image. The Spot AE and high bright spot suppression algorithms of SONY FCB-ER9500 can precisely adjust parameters for local overexposed areas in the picture, such as car lights and reflective metals.
Medical application: During endoscopic surgery, when the lens approaches moist tissue, the reflective spot may cover the lesion area. FCB-ER9500 ensures that doctors can clearly observe the microstructure of the mucosa by identifying and suppressing bright areas.
Security surveillance: In the surveillance of jewelry stores, the reflection on the display cabinet glass often blocks the facial features of customers. The module can automatically locate the reflective point and reduce its brightness while maintaining normal exposure in other areas.
Iii. Technical Ecosystem: A complete Solution from hardware to software
1. Hardware synergy: Dual guarantees of anti-shake and noise reduction
The strong light suppression of FCB-ER9500 is not an isolated technology but works in conjunction with the following functions:
Super+ Anti-shake Mode: In the field of intelligent transportation, even if the camera shakes violently, the strong light suppression algorithm can still stably output a ghosting image.
3D noise reduction technology: In low-light conditions, SONY FCB-ER9500 uses 3D+2D coordinated noise reduction to ensure that the image is gray-free after strong light suppression.
2. Software support: Customized solutions for secondary development
Shenzhen Xuanzhan Technology, as the official authorized distributor of SONY (China), has developed multiple high-performance coding control boards for the flagship 4K ultra-high-definition camera module FCB-ER9500, including mainstream interface types such as 4K HDMI, 12G-SDI, IP network and USB Type-C. These control panels can collect and output 4K ultra-high-definition video signals captured by the FCB-ER9500 in real time. While achieving high-quality video conversion and stable transmission, they also support adjusting parameters such as zoom, focus, exposure, and white balance of the camera module through external instructions. So as to meet the integrated application requirements in high-demand scenarios such as unmanned aerial vehicles, medical imaging, and video conferencing.
Summary
In complex environments where strong light and dark shadows interweave, SONY FCB-ER9500, with its high dynamic range, wide dynamic range, intelligent high bright spot suppression and multi-scenario verification, provides a “fearless of strong light” visual solution for fields such as medical care, transportation and industry.
