VERFAHREN UND ANORDNUNG ZUM ERZEUGEN EINES STANDBILDES MIT HOHER AUFLÖSUNG

摘要

A method and arrangement is disclosed for creating a high-resolution still picture. A sequence of lower-resolution pictures is subjected to motion-compensated predictive encoding, preferably by an MPEG encoder producing an IPPP. sequence of encoded pictures. The relatively small differences between successive pictures, which are due to motion of the image sensor or motion in the scene, become manifest in motion vectors with sub-pixel accuracy. The high-resolution picture is then created from the decoded pictures and the motion vectors generated by the encoder. The invention is particularly applicable in electronic still picture cameras with a storage medium. The MPEG encoder takes care of data compression, and the decoder also allows playback of the original moving video sequence.
