Image quality - GCSE Computer Science Definition

Reviewed by: James Woodhouse

Published

Image quality refers to how clear and detailed an image looks on a screen or when printed. It depends on several factors, like resolution, which is the number of pixels that make up the image. More pixels generally mean a sharper and clearer picture. Other factors include brightness, contrast, and colour accuracy. Brightness is how light or dark the image appears, contrast is the difference between the lightest and darkest parts, and colour accuracy is how true the colours are to real life. Higher image quality means the image looks more lifelike and easier to understand, which is important in areas like photography, video games, and computer graphics.
