TECHNICAL CORNER

AXIS SUPERIOR IMAGE QUALITY

Image quality is one of the most important features of any camera, if not the most important. This is particularly so in surveillance and monitoring applications, where lives and property may be at stake.

Determining factors

Unlike traditional analog cameras, Axis network cam- eras are equipped with processing power not only to capture and present the images, but also to digitally manage and compress the video for network transport. There is a natural trade-off between levels of compres- sion and image quality. But even so, image quality can vary considerably, depending on choice of optics and image sensor, available processing power and level of sophistication of the algorithms. To summarize, one should specifically look at the aspects of

>Type of image sensor

>Low light capabilities of the camera

>Ability to replace the lens

>Resolution

>Supported compression standards

>Image capture technology

Why is Axis image quality superior?

Since the development of network cameras first began, Axis introduced a stream of image enhancing technol- ogies and patents. From a technical point of view, Axis’ Superior Image Quality rests on three pillars:

>Advanced signal processing, image enhancement algorithms and video compression technologies

>Custom-designed image processing and video networking chips

>Careful selection and matching of the latest image sensors and lenses
