Interactive desktop display system for automatically adjusting pan and zoom functions in response to user adjustment of a feedback image

摘要

An interactive desktop system for automatically adjusting pan and zoom functions to change a field of view in response to user actions relative to a feedback image projected on a source document. The interactive desktop system includes an image capture system, a display system and a processor system. The image capture system grabs an image from the source document in its field of view. The display system indicates to a user the captured image using the feedback image, which is visible to the image capture system. In response to a user adjustment of the feedback image, the processor system adjusts either the pan or zoom function of the image capture system, thus changing the field of view of the image capture system.
