Endoscope System and Coordinate System Correction Method
Summary
USPTO granted Patent US12593962B2 to Olympus Corporation covering an endoscope system with automated coordinate correction. The patent describes methods for detecting endoscope movement direction, estimating moving body areas in captured images, and calculating deviations between endoscope and moving device coordinate systems to enable automatic correction.
What changed
USPTO granted Patent US12593962B2 to Olympus Corporation for an endoscope system with integrated coordinate system correction. The patent includes claims covering: detection of endoscope movement via a moving device coordinate system; estimation of moving body areas in endoscope images; calculation of coordinate deviations between endoscope and moving device reference frames; and automatic correction of the moving device coordinate system based on detected deviations. The patent contains 20 claims and was filed on March 20, 2024.
Medical device manufacturers developing endoscopic systems with robotic or motorized movement capabilities should review this patent's claims for potential overlap with their own coordinate tracking and correction technologies. The patent's broad claim language covering 'movement direction detection' and 'coordinate deviation calculation' may affect product development strategies in surgical robotics and automated endoscopy.
What to do next
- Monitor for competitive patents in endoscopic coordinate correction technology
- Review claims to assess potential infringement exposure in medical imaging products
- Evaluate whether proprietary systems utilize similar coordinate correction methods

Abstract
An endoscope system includes: an endoscope; a moving device that holds and moves the endoscope; and at least one processor. The at least one processor is configured to: detect a movement direction of the endoscope moved by the moving device in a coordinate system of the moving device; estimate an area of a moving body in an image captured by the endoscope; detect a movement direction of an object in the image on the basis of another area in the image excluding the area of the moving body; calculate a deviation between a coordinate system of the endoscope and the coordinate system of the moving device on the basis of the movement direction of the endoscope and the movement direction of the object; and correct the coordinate system of the moving device on the basis of the deviation.
