Sony FCB camera block
In fields such as security monitoring, industrial inspection and field investigation, imaging in the absence of supplementary lighting at night has always been a huge challenge. Traditional cameras often require auxiliary light sources when there is insufficient light, but this also means increased power consumption and exposure risks.
Xuanzhan Technology, the official authorized distributor of SONY (China), solemnly recommends the SONY FCB-EV9500L, which redefines the possibilities of night imaging.
So, what exactly makes this camera stand out? How does it manage to capture clear color images in an almost completely dark environment? Let’s uncover the mystery of this super starlight-level visible light camera together.
1. Starlight-level low illumination: Breakthrough performance of 0.00008Lux
The minimum illuminance of SONY FCB-EV9500L in ICR-On mode can reach 0.00008Lux (shutter speed 1/30 second), which has reached the standard of starlight-level cameras.
This means that even in extremely dark environments with only starlight, it can capture high-definition images without any external auxiliary light sources. Compared with ordinary low-light cameras, the SONY FCB-EV9500L effectively avoids trailing and ensures the demand for 24-hour high-quality monitoring.
Low-light cameras can be classified into several levels based on their performance: normal level (0.1Lux), low light level (0.01Lux), moonlight level (0.001Lux), and starlight level (0.0001Lux and below). The 0.00008Lux index of the FCB-EV9500L places it among the ranks of super starlight cameras.
Ii. Four Technical Pillars: The Core Secrets Supporting Outstanding Low-light Performance
1. Large aperture lenses: The foundation for more light intake
The SONY FCB-EV9500L features a large aperture lens ranging from F1.6 to 4.8. The larger lens diameter ensures more light intake.
It is worth mentioning that its lens adopts a 7-blade aperture structure. Compared with the traditional 2-blade structure, it can effectively reduce diamond-shaped halos and double images, making the resulting glare and halos closer to a circle, thereby significantly improving image quality.
2. Large target surface image sensor: The core of light-sensing capability
The SONY FCB-EV9500L features a 1/1.8-inch STARVIS CMOS sensor with approximately 4.17 million effective pixels. A larger sensor target surface size means that each pixel unit can absorb more ambient light.
Meanwhile, the SONY FCB-EV9500L adopts a new pixel unit structure and circuit technology. Compared with its predecessor, the FCB-EV7520, its sensitivity has been increased by a full two times. STARVIS CMOS sensors are renowned for their outstanding light-sensing performance, achieving superior clarity even in dark alleys without street lamps.
3. Powerful image processing chip: Intelligent optimization algorithm
Low-light environments often introduce image noise, affecting the clarity of the picture. The SONY FCB-EV9500L is equipped with a powerful processing chip featuring automatic gain control and digital noise reduction.
The automatic gain function can maintain the image brightness at an ideal state in low light conditions and control the noise level. Digital noise reduction technology can effectively filter out noise, present a purer picture and retain more image details.
The SONY FCB-EV9500L also supports 2D/3D noise reduction, further enhancing the clarity of the picture.
4. Low-light enhancement algorithm: The wisdom of software
Even based on the same hardware platform, the final effects of different products may vary greatly, which mainly depends on the algorithm optimization capabilities of the manufacturers.
The low-light enhancement algorithm of SONY FCB-EV9500L performs exceptionally well in noise reduction and gain processing. Take noise reduction as an example. Improper noise reduction processing can cause the image to have a foggy effect, trailing and loss of detail. When it comes to setting the gamma value, if it is too high, the contrast of the picture will increase but details will be lost; if it is too low, the image will become brighter but the transparency will deteriorate.
SONY’s algorithm has found the best balance among numerous parameters, ensuring that clear and natural images can still be obtained in low light conditions.
Iii, multi-interface video output, expanding more possibilities
Xuanzhan Technology, with its profound accumulation of 16 years in the secondary development of SONY FCB camera modules, has independently developed and built a product matrix of coding control boards that comprehensively cover various interfaces such as 3G-SDI, HDMI, USB3.0, Type-C, IP, CVBS and MIPI. These control boards can convert the video signals collected by SONY FCB-EV9520L into different formats of high quality, to meet the specific requirements of high-definition video collection, conversion and transmission in various scenarios such as unmanned aerial vehicle inspection, medical imaging, industrial inspection, security monitoring, robots and video conferencing. Through this flexible interface solution, Xuanzhan Technology has effectively reduced the system integration threshold and development costs for users.
Conclusion: An ideal choice for shooting in a night environment without supplementary lighting
The SONY FCB-EV9500L, through its large-aperture lens, large sensor, powerful processing chip and advanced algorithms, has achieved the ability to capture clear images in the night without any fill light, truly realizing “starlight-level” low-light imaging.
With Xuanzhan Technology’s diverse interface coding control board product matrix, the SONY FCB-EV9500L can provide reliable all-weather visual solutions for security monitoring, industrial inspection, and field exploration, making the night no longer an obstacle to vision.
