Abstract
During the compression of digital image data, the desired level of detail, therefore the compression level, is defined at different values “for different image regions”. The definition of the level of detail can be automatic and/or controlled by the user. As a result of this it can be achieved for more interesting image regions to be less compressed or not at all compressed, whereas less interesting image regions are greatly compressed.
