Patent ID: 8862209

Claim:
A surgical imaging device, comprising: an image sensor configured to generate image data corresponding to a surgical site; a video processor configured to receive from the image sensor the image data and to process the image data; a display device coupled to the video processor, the video processor configured to generate a display image oriented in a first direction for display on the display device; wherein the video processor is configured to display further images in an orientation that is the same as the first orientation, even when an orientation of the image sensor is changed; wherein the video processor is configured to stabilize the display image by comparing a current image frame to a reference image frame, the current image frame divided into a plurality of current image regions and the reference image frame divided into a plurality of reference image regions; and wherein the video processor is configured to evaluate a motion vector and an alignment vector for each current image region of the current image frame by selecting the reference image region of the reference image frame that has a minimum number of correlation co-efficients relative to the current image region of the current image frame.
