Image compression
Image compression reduces the file size of an image. This is particularly important when

Digital image processing. The goal is to correct errors made during image generation
(caused by overexposure, underexposure, blurring, weak contrast, image noise, etc.) in
order to create a “better“ image.

Abbreviation for Joint Photographic Experts Group, responsible for the development of the
JPEG standard method for image compression. JPEG is the most common lossy image
format for photos on the Internet. Loss in image quality is barely noticeable at compression
rates lying between 60% and 99%.
Latency
Time interval elapsed between the time an image is captured by a camera and when that
same image is displayed on the monitor.
Layout
Describes the layout of video sources on a screen in MxControlCenter. The layout determines

from network cameras. In addition to the actual video images, you can also incorporate
