In the digital operating room, the core mission of the surgical field camera is to clearly present the surgical details. However, the "light spots" formed by the strong light reflection of the shadowless lamp have long troubled clinical operations - overexposed areas cover up key anatomical structures, and the details in the dark areas are lost due to insufficient exposure, and even interfere with the doctor's judgment of the lesion.
How can surgical field cameras achieve true color reproduction even under strong light? At the 93rd China International Medical Equipment Fair from April 9th to 12th, 2026, Our company will showcase the combination of Sony FCB camera modules and surgical field cameras under surgical lights. On-site, they will reveal the three major light spot resolution technologies of side-mounted and center-mounted surgical field cameras, providing a solid solution for upgrading the visual system in operating rooms.
The multi-head design of the operating room light reduces shadows, but when the strong light directly hits the surface of the surgical instruments or tissues, the reflected light can exceed the dynamic range of the camera sensor, forming white spots. Traditional solutions, such as globally reducing the exposure, can lead to the loss of details in the dark areas (such as deep cavities), creating a contradiction between "preserving the bright areas" and "preserving the dark areas". Moreover, due to the difference in installation angles, the mechanisms of spot formation for the side-mounted surgical field camera and the center-mounted surgical field camera are distinct:
1. Side-mounted surgical field camera: It is prone to direct reflection entering the lens due to the small angle between the lens and the light axis of the operating room light.
2. Center-mounted surgical field camera: Although its light axis is more aligned with the operating room light, dynamic reflections during instrument operation can still cause local overexposure.
Our company, in collaboration with Sony's medical-grade camera modules, has developed a solution through hardware innovation, algorithm optimization, and system coordination, which can perfectly solve the spot problem.
1. Hardware Innovation: Sony Engine + Multi-layer Coated Lens
Sony FCB-EV9520L Engine: Equipped with Sony's new-generation STARVIS 2 CMOS sensor, it supports 1080P full high-definition resolution and 30x optical zoom. Through multi-frame synthesis technology, it covers a high dynamic range of 130dB, simultaneously preserving details in both bright areas (such as instrument reflections) and dark areas (such as periodontal pockets).
Medical-grade optical zoom lens: It adopts a 30x zoom medical-level lens coated with multi-layer films with low reflectivity to block stray light paths and physically suppress the generation of glare, which can to a certain extent prevent the formation of light spots.
2. Intelligent algorithms: Automatic strong light suppression + spectral customization
(1) Automatic strong light suppression
To address the "ghosting" and glare caused by direct illumination from surgical lamps, Our company's surgical field camera, based on Sony's integrated core, is embedded with an automatic strong light suppression algorithm. The system continuously monitors the brightness histogram of the image, accurately locates overexposed areas (such as the reflection points of metal instruments), and dynamically adjusts the exposure in different zones. This ensures that the overall image brightness is not compromised while specifically darkening the overexposed spots, maintaining a clear and bright image without any dead white areas.
(2) Shadowless Light Spectrum Customization Engine
Relying on Sony's advanced ISP image processing capabilities, the side-mounted or center-mounted surgical field cameras can analyze the unique spectral characteristics of different brands of shadowless lights. By dynamically adjusting the gamma curve and white balance matrix, the algorithm can specifically filter out the specific wavelength stray light that causes reflection. Whether it is the sharp penetration of cold white light or the soft rendering of warm yellow light, it can achieve "removing the false and retaining the true" - eliminating light spots while highly restoring the true color of tissues and avoiding color distortion.
3. System Synergy: Shadowless Light Specialized Control Software + Laser Positioning
(1) Shadowless Light Specialized Control Software: Solving the Persistent Problem of Surgical Field Overexposure
In response to the core pain point of surgical field light spot overexposure and loss of tissue details caused by direct shadowless light in digital operating rooms, Our company, based on 16 years of video low-level development experience, has independently developed and launched a shadowless light specialized control software with software copyright patent.
This technology, through a unique algorithm architecture, not only fundamentally solves the long-term bottleneck of light spot overexposure that restricts the quality of surgical video recording, but also achieves clinical-level high-fidelity color restoration. This provides a solid low-level image technology support for standardized surgical teaching recording and precise remote diagnosis.
(2) Laser-assisted positioning system: Physical-level accurate light avoidance
Our company's field camera innovatively integrates a laser-assisted positioning system. This system emits guiding lasers to assist medical staff in quickly adjusting the lens axis to the optimal non-reflective angle, eliminating glare caused by the lens directly facing strong light sources from the source and achieving precise physical-level positioning and optical protection.
Overexposure of light spots is not a technical limitation but an engineering problem that can be systematically solved. The collaborative innovation of Our company with Sony Medical and the core module has set a new benchmark for the surgical room visual system - from hardware to algorithms, from single machines to systems, guided by clinical needs, ensuring that every surgery is carried out accurately in a clear and flawless field of vision. At the Shanghai CMEF 2026 site, we invite you to witness together the solution to the light spot problem of the side-mounted and center-mounted surgical field cameras!
