2results about How to "Improve focusing efficiency" patented technology

This invention relates to the field of image processing technology and discloses a focusing method for an endoscope system and an endoscope system. The method includes: step S1, acquiring the current image captured by the endoscope at the current focal length; step S2, determining the candidate focusing region on the current image; step S3, determining the sharpness evaluation value of the candidate focusing region; step S4, determining whether the sharpness evaluation value meets the preset sharpness condition; if not, changing the focal length of the endoscope and returning to step S1; if yes, determining that the endoscope system has completed focusing. This invention effectively addresses the problem of incorrect focusing, not only achieving more precise focusing and ensuring the acquisition of high-quality images, but also improving focusing efficiency, reducing the risk of blurring, and effectively enhancing the safety and effectiveness of medical operations.
