BILDÜBERTRAGUNGSSYSTEM MIT EINER VORSCHAUMODE.

摘要

A still image communication system performs a block cosine transformation on an image of bandwidth compression. A transmitter subsamples a full resolution image, to provide a preview image, and transforms and transmits the preview image prior to transforming and transmitting the full resolution image. A receiver and displays the preview image, and replaces the preview image on the display block-by-block as the full resolution is received.
