Abstract
An image transmitting remote object examination device includes (a) an image-recording system at the location of the object to be examined, (b) an observation station located at a distance from the image-recording system for the evaluation of the image and for the remote control of the image-recording system, and (c) an intervening, narrow band telecommunications link, by way of which the images taken are transferred to the observation station using image data compression and/or reduction together with the remote control commands to the image system. A system status-determining unit continuously records the overall system status relevant to image transmission, and dependent upon the overall system status, variably controls the image data compression and/or reduction and/or the number of individual telecommunication channels used in a transmission packet. The image quality required for a particular situation, together with the optimal on-line image impression, is thereby obtained.
