Title:
IMAGE PROCESSING METHOD FOR ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2022/027878
Kind Code:
A1
Abstract:
An image processing method for an endoscope comprises: acquiring an image frame sequence comprising multiple image frames, and dividing each image frame to obtain multiple image blocks (S11); acquiring feature values and image information of the multiple image blocks (S12); determining attributes of respective image blocks in each image frame according to the feature values (S13); determining weighting parameters of the respective image blocks in each image frame according to the attributes, and obtaining a weighting parameter set according to the weighting parameters (S14); performing weighted average calculation according to the weighting parameter set and the image information of the image blocks located at the same position in the multiple image frames so as to obtain target image information of the multiple image blocks (S15); and combining the target image information of the multiple image blocks into a target image frame (S16). The above arrangement can prevent image smearing occurring when the images depict an object moving at a high speed.
