Nowadays, UAV cameras are applied in numerous fields including aerial photography, agricultural plant protection, express delivery, disaster rescue, wildlife surveying, mapping, news reporting, power line inspection, disaster relief, film‑and‑television shooting, and other scenarios. UAV cameras provide photography enthusiasts with an "eye in the sky", enabling them to capture many spectacular shots rarely seen from the ground. Nevertheless, a qualified UAV camera has to meet relevant functional requirements. Do you know whether noise‑reduction function is required for UAV cameras? Kaimorui’s editor gives the introduction below.

UAV cameras do have requirements for noise‑reduction function.

The noise‑reduction function of a UAV camera optimizes and eliminates image noise. Noise may occur with long‑time exposure, mostly when shooting night‑scene footage at low ISO values, manifested as scattered bright speckles in the dark night sky. This happens because the processor is overloaded by heavy workload brought by slow shutter speed, causing certain pixels to malfunction. When the noise‑reduction function of the UAV camera is enabled, captured images will become clearer and smoother to deliver high‑definition visuals.

To achieve superior image quality, apart from noise‑reduction capability, UAV cameras should be equipped with larger sensors and higher‑resolution pixels. UAVs normally fly at a certain altitude for safety purposes, and captured photos often need zoom‑in post‑processing. To retain sharpness after magnification of photos and videos, UAV cameras with at least 4K resolution are recommended.

To sum up, noise‑reduction function is a necessary feature for UAV cameras. Only with this function turned on can the device produce clear, smooth high‑definition images and videos for end‑users.
