Endoscope System and Method of Operating the Same - US12593967B2
Summary
USPTO granted Fujifilm Corporation patent US12593967B2 for an endoscope system with exposure control based on brightness detection of edge portions of endoscope images. The system calculates brightness information indicating the degree of brightness of edge portions and controls a tracking speed of exposure amount using a suppression coefficient. The patent includes 12 claims covering the exposure control method and system architecture.
What changed
USPTO granted a patent to Fujifilm Corporation for an endoscope exposure control system that analyzes brightness of edge portions in endoscope images and applies a suppression coefficient to control the tracking speed of exposure adjustments. The invention improves image quality consistency during endoscopic procedures by comparing current brightness information against historical data to smooth exposure transitions. Medical device manufacturers developing endoscopic imaging systems should review this patent to assess potential overlap with their own product development and to consider licensing opportunities for exposure control technology in diagnostic and surgical imaging applications.

Abstract
An endoscope system includes a processor, in which the processor performs exposure amount control based on an endoscope image captured by an endoscope including an imaging element, calculates brightness information indicating a degree of brightness of an edge portion of the endoscope image, and controls a tracking speed of the exposure amount control according to the brightness information. The brightness information is compared with past brightness information, which is the brightness information in the past, and a suppression coefficient for suppressing a change amount or a change rate of an exposure amount, which is decided according to a comparison result, is applied to the exposure amount control to control the tracking speed.
