Sony FCB camera block
In the practical application scenarios of digital operating rooms, the problem of overexposure of the shadowless lamp’s light spot is like a stubborn “stumbling block”, not only existing for a long time but also extremely difficult to solve, causing great trouble and distress to many users of medical operating rooms – strong light reflection leads to local image distortion and detail loss in the surgical field, which not only affects the accuracy of surgical operations It further restricts the quality of real-time image transmission and remote collaboration.
How does the high-definition surgical video camera equipped with the SONY FCB-EV9520L zoom camera block effectively solve the problem of overexposure of the shadowless lamp’s light spot through multi-directional coordination?
1. Highly Realistic color reproduction: The advantage of SONY FCB camera block
In the complex and harsh lighting environment of the operating room, the overexposure problem of the light spot of the surgical video camera has always been a “stumbling block” affecting the accuracy of the surgery. SONY FCB-EV9520L, with its outstanding true-to-life color reproduction ability, has brought a glimmer of hope to solve this problem.
Its advanced image sensors and powerful image processing chips work in concert to precisely capture every subtle color change in the field. When the shadowless lamp shines strongly, ordinary cameras may fail to accurately process the light, resulting in local overexposure and color distortion in the picture.
However, the SONY FCB-EV9520L is different. It can intelligently adjust the intake and processing of light based on real color information, avoiding excessive enhancement of local light spots. Even under strong light, it can clearly present the true color and details of tissues, blood vessels, etc., and will not mask key information due to overexposure. This enables doctors to more accurately assess the condition of the surgical site and perform precise operations, significantly enhancing the safety and success rate of the surgery and providing patients with more reliable medical security.
Ii. Automatic Strong Light Suppression: Smart “Light and Shadow Master”
In the complex lighting environment of the operating room, the surgical video camera often overexposes local light spots due to direct exposure of strong light sources such as shadowless lamps, resulting in the loss of key tissue details and affecting the accuracy of the surgery. The automatic strong light suppression function of SONY FCB-EV9520L is like an intelligent “master of light and shadow”, providing an efficient solution to this problem.
This function of SONY FCB-EV9520L relies on advanced image sensors and intelligent algorithms to monitor the strong light areas in the picture in real time. Once it detects overexposure spots caused by strong light sources such as shadowless lamps, it will quickly activate the dynamic adjustment mechanism to precisely reduce the exposure of that area, while skillfully balancing the brightness and color of the surrounding images.
In precise operation scenarios such as heart surgery, even when the shadowless lamp is directly exposed to the heart area, the SONY FCB-EV9520L can ensure that details such as heart tissue and blood vessels are clearly presented, without blurring due to overexposure. Doctors can accurately assess the condition of the surgical site and perform precise operations based on clear and stable images, significantly enhancing the safety and success rate of the surgery and building a solid defense line for patients’ lives and health.
Iii. Regional Independent 3A Function: Precisely lock the focus of the surgical field
The SONY FCB-EV9520L supports independent control of three areas: Auto Exposure (AE), Auto Focus (AF), and Auto White Balance (AWB). Users can customize rectangular areas as optimization benchmarks. For example:
In neurosurgery, the focus can be locked on the brain tumor area, while independently suppressing the exposure of the strong light area outside the window to avoid interference from the reflection of the shadowless lamp.
During endoscopic surgery, the center of the surgical field is marked by a laser-assisted positioning system, and the software automatically adjusts the color restoration parameters of this area to ensure that the slightest tremors of blood vessels and nerves are clearly visible.
Four. Advanced Software Algorithms: Multiple Improvements to the Light Spot Problem
The advanced software algorithm of SONY FCB-EV9520L can improve the spot problem of surgical video cameras from multiple dimensions:
130dB ultra-wide dynamic range: The SONY FCB-EV9520L is equipped with a SONY STARVIS 2 CMOS sensor, doubling the sensitivity. It can simultaneously capture high-brightness areas (such as metal instruments) and dark details (such as tissue texture) under the strong light of the shadowless lamp.
Frame synthesis technology: By comparing multiple frames of images, it identifies the position of strong light and adjusts the gain and exposure time of local pixels in real time. In the scenario of unmanned aerial vehicle (UAV) inspection of high-voltage lines, even in the face of strong light from arc discharge, the system can still stably output the details of the conductors.
3D+2D hybrid noise reduction: Suppress noise caused by strong light, avoid dynamic disturbances such as swaying leaves and flying insects, and ensure that the license plates and textures of moving targets (such as vehicles at tunnel entrances) are clear.
V. Hardware Synergy: The deep integration of SONY modules and Control Software
Xuanzhan Technology’s dedicated control software for shadowless lamps is deeply compatible with SONY’s FCB-EV9520L and can intelligently adjust the camera parameters according to different surgical scenarios. The software accurately analyzes the position and intensity of the light spot, quickly adjusts the image exposure, ensuring that the surgical field image is always clear and the colors are true, providing doctors with high-quality visual protection and facilitating the smooth progress of the surgery.
Summary
In response to the pain point of overexposure of light spots in digital operating rooms, Xuanzhan Technology, relying on the official authorized distribution qualification of Sony (China) and 16 years of accumulation in high-definition video secondary development (2010-2025), has deeply integrated the technical advantages of Sony FCB series camera modules and meticulously developed a dedicated control software for shadowless lamps. Through this innovative system solution, the problem of overexposure of the light spot of the surgical video camera has been systematically overcome, providing a strong guarantee for the efficient and precise operation of the digital operating room.
