Electronic Picture Base

摘要

The electronic processing and filing of large quantities of pictures was studied. An approach to the architecture of decentralized picture-processing/picture-base systems is described. The signal processing tasks, control tasks, and management task are to be performed in separated system levels. For the signal level a concept was developed for a fast and flexible picture processor, and methods for the implementation of picture operation, in particular picture coding processes, were elaborated. A state-of-technology review of peripheral devices was performed. Extensive investigations were carried out concerning electrostatic grey-tone printing. Promising results were achieved with the electrophoretic process and an experimental system was assembled to study architectural problems as well as to test peripheral devices.
