Abstract

A system and method for automatically configuring a display device for an endoscopic procedure. The system includes: a video processing device for receiving image signals of an object from an endoscope device. A first converting device converts the image signals provided by a standard definition endoscope device into first resolution video image signals for display on a display device; or, converts image signals provided by a high definition endoscope device into second higher resolution video image signals for display. A second converting device converts the second higher resolution video image signals into first resolution video image signals image signals. A processing node receives: the first resolution video image signals from either the first converter means, or from the second converter means. An image capture means at the processing node captures still images of the first resolution video image signals received. The processing node further routes back to the video processing device the first resolution video image signals from the image capture card. A switching device receives the first resolution video image signals from the image capture card and routes the first resolution video image signals to the first display device or, alternately, receives the video image signals from the first converting means for routing to the first display device.
