Abstract

First compressed data is decoded to obtain a representation of an image at a first level of quality which is output for display. In response to a predetermined trigger event, second compressed data is decoded to obtain reconstruction data, and the reconstruction data is used to reconstruct a representation of part of the image at a second, higher level of quality using the representation at the first level of quality. The representation of part of the image is output for display at the second level of quality.
