AUTOMATIC XY CENTERING FOR DIGITAL MICROSCOPE
First Claim
1. A system configured for automatically centering in an XY plane a field of view of a patient'"'"'s eye under high magnification during ophthalmic surgery, the system comprising:
- a processor; and
a non-transitory computer-readable medium accessible to the processor containing instructions executable by the processor for;
acquiring, from a photosensor, a real-time video signal representing a field of view comprising the patient'"'"'s eye under high magnification by a microscope, wherein the field of view comprises an en-face XY plane;
displaying on a display at least one view within the field of view corresponding to the real-time video signal;
detecting a circular image in the real-time video signal, wherein the circular image comprises a target image in the field of view;
determining the location of the center of the circular shape within the XY plane of the field of view;
determining the location of the center of the field of view in the XY plane;
comparing the location of the center of the circular image and the location of the center of the field of view;
upon determining a difference in the locations of the center of the circular image and the center of the field of view, transmitting a movement instruction to a motorized microscope support configured to move the location of the microscope field of view in the XY plane, wherein the movement instruction directs movement of the microscope field of view to place the center of the field of view at the location of the center of the circular image;
thereby automatically moving the center of the field of view to the center of the circular image detected in the real-time video signal acquired from the field of view of the patient'"'"'s eye under high magnification during ophthalmic surgery.

Abstract
A method and system are described for automatically centering in an XY plane a field of view of a patient'"'"'s eye under high magnification during ophthalmic surgery. The method includes automatically moving the center of the field of view to the center of a circular image detected in a real-time video signal acquired from the field of view of the patient'"'"'s eye under high magnification during ophthalmic surgery. The system configured to perform the method has a processor and a non-transitory computer-readable medium accessible to the processor containing instructions executable by the processor to perform the method.

15. A method of automatically centering in an XY plane a field of view of a patient'"'"'s eye under high magnification during ophthalmic surgery, comprising the steps of:
-
acquiring, by a processor executing instructions contained in a non-transitory computer-readable medium, from a photosensor, a real-time video signal representing a field of view comprising the patient'"'"'s eye under high magnification by a microscope, wherein the field of view comprises an en-face XY plane; displaying on a display, via the processor executing instructions contained in the non-transitory computer-readable medium, at least one view within the field of view corresponding to the real-time video signal; detecting a circular image in the real-time video signal, by the processor executing instructions contained in the non-transitory computer-readable medium, wherein the circular image comprises a target image in the field of view; determining, by the processor executing instructions contained in the non-transitory computer-readable medium, the location of the center of the circular image within the XY plane of the field of view; determining, by the processor executing instructions contained in the non-transitory computer-readable medium, the location of the center of the field of view in the XY plane; comparing, by the processor executing instructions contained in the non-transitory computer-readable medium, the location of the center of the circular image and the location of the center of the field of view; and upon determining a difference in the locations of the center of the circular image and the center of the field of view, transmitting, by the processor executing instructions contained in the non-transitory computer-readable memory, a movement instruction to a motorized microscope support configured to move the location of the microscope field of view in the XY plane, wherein the movement instruction directs movement of the microscope field of view to place the center of the field of view at the location of the center of the circular image; thereby automatically moving the center of the field of view to the center of the circular image detected in the real-time video signal acquired from the field of view of the patient'"'"'s eye under high magnification during ophthalmic surgery.
