A method of transferring digital image data over a communication link transforms and orders the data so that, as data is received by a receiving station, a low detail version of the image is immediately generated with later transmissions of data providing progressively greater detail in this image.

A method of transferring digital image data over a communication link transforms and orders the data so that, as data is received by a receiving station, a low detail version of the image is immediately generated with later transmissions of data providing progressively greater detail in this image. User instructions are accepted, limiting the ultimate resolution of the image or suspending enhancement of the image except in certain user defined regions. When a low detail image is requested followed by a request for a high detailed version of the same image, the originally transmitted data of the low resolution image is not discarded or retransmitted but used with later data to improve the originally transmitted image. Only a single copy of the transformed image need be retained by the transmitting device in order to satisfy requests for different amounts of image detail.

[ We claim:] [1.] A method of transmitting a digital image comprised of spatially arrayed pixels denoting shade information from a transmission site to a reception site, the method comprising the steps of:(a) ordering the image data according to a pre-defined visual significance of the image data;(b) transmitting in the ordering of step (a) the image data of a first field of the digital image from the transmission site to the reception site;(c) receiving the image data at the reception site and displaying the first field of the digital image as the image data is received;(d) during the transmission of the image data of the first field, accepting from the reception site, instructions defining a second field within the first field; and(e) when instructions are received continuing the transmission in order of the image data excluding data not in the second field;(f) when instructions are not received, continuing the transmission of all image data until completion;including the step of:(g) upon completion of the transmission of the image data for the second field continuing the transmission in order of the excluded data of the first field.
