Unmanned Aerial Vehicle (UAV) is an unmanned aerial vehicle operated by radio remote control equipment and self-provided program control device. Uav is actually a general term for unmanned aerial vehicle. From the technical point of view, it can be divided into unmanned fixed wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parachute aircraft and so on. Compared with manned aircraft, it has the advantages of small size, low cost, easy to use, low environmental requirements, strong survivability and so on.
In terms of civil use, UAV + industrial application is the real demand of UAV. Now it is mainly used in aerial photography, agriculture, plant protection, express transportation, disaster rescue, wildlife investigation, surveying and mapping, news reporting, electric power inspection, disaster relief, film and television photography, romance and other fields. So, what functions do drone cameras need to have?
SONY FCB-EV7100 adopts SONY’s new Exmor TM CMOS sensor and unique ISP, equipped with 10x optical zoom lens and 12x digital zoom, effective output of high definition picture, With fast auto focus, wide dynamic, fog through, wide dynamic, noise reduction, low light, automatic day and night conversion and other functions, can meet the functional requirements of UAV camera?

1. fast auto focus
Uav is constantly moving, which has high requirements on the automatic focusing of the camera. In the process of flight, it is necessary to quickly focus and image objects and obtain high-definition pictures.
2. Wide dynamic
When the UAV camera is used to shoot the scene with large contrast between light and dark or backlit, the bright area in the whole image will be overexposed, the dark area will be underexposed, and the brightest and darkest part of the image will not be seen clearly. The wide dynamic function of the camera can perfectly solve the above problems.

3. Through fog
When the UAV camera shoots in a rainy and wet environment, fog will inevitably occur. In this case, it will seriously affect the shooting effect and fail to reach the ideal state. At this time, it is necessary for the UAV camera to have the function of fog penetration. The screen also habitually adjusts the scene pixel by pixel. Even in the smoky environment can also take a more clear picture.
4. Noise reduction
Uav camera noise reduction function, noise reduction function is the pointer to optimize and eliminate noise. Long-term exposure noise, this phenomenon mainly appears in the use of low ISO photography night scene, in the picture of the dark night sky, there are some messy highlights. It can be said that the reason is that the processor cannot handle the huge workload caused by the slow shutter speed, so that some specific pixels lose control. When the noise reduction function of the UAV camera is enabled, the picture taken will be relatively clear and smooth.

5. low light
Low-light performance has little influence on the surface of UAV camera, but for some specific environments, such as early morning, dusk, night, tunnel and other situations with insufficient light, low-light performance is essential to achieve better picture effects.
6. automatic day and night switch
Uav cameras are widely used, and the automatic day-night conversion function is essential. In low light environment, the camera component actively switches from day form to night form, removes infrared filters, and improves sensitivity so that clear pictures can be taken at night. It is required to provide clear pictures uninterrupted day and night in different environments. When the lighting conditions often change, the camera should also have high picture quality.
How to choose the UAV camera? It is also necessary to match according to the application environment. Shenzhen Xuanzhan Technology recommends SONY FCB-EV7100, which has the necessary main performance of UAV camera, and is also small in volume and weight, which can effectively reduce the power consumption of UAV and delay the flight time of UAV. In addition to SONY FCB-EV7100, Xuan Zhan Technology, an official authorized distributor of SONY, can provide full HD 7 series, 4K Ultra HD 8 series and the latest 9 series, which can meet the various needs of different users.
