Image storage and transmission systems.

摘要

To reduce the quantity of data stored to define visual images electrical signals defining the images are digitised and analysed on a pixel-by-pixel basis to determined boundaries between zones having differing textures and the textures within the zones. Only data defining the zone boundaries and zone textures needs to be stored thus allowing a larger number of visual images to be held in a store than would be possible if full TV data were to be used. An image reconstitutor capable of synthesising signals defining an approximate replica of the original visual image from the data defining the zone boundaries and textures is disclosed. By linking the analysis apparatus and synthesising apparatus using a transmission line an image transmission system is provided.
