Video image data produced by an image sensor or the scanner circuitry of a digital camera contain both signal and noise information. Noise is especially present a low light images. This not only degrades image quality, but also significantly increases the data size for transmission and storage. Accordingly, reducing the noise from an image is a critical function of video processing technology.
This whitepaper provides an in-depth look at Hikvision’s noise reduction solutions, including:
In combination with other Hikvision technologies, these can drastically increase signal quality and decrease storage and bandwidth loads.
