Abstract

To provide means for measuring the blood flow rate of gastric subepithelial microvessel in real time. An endoscope system for measuring the blood flow rate of gastric subepithelial microvessel comprises a magnifying endoscope and a blood flow video data processing unit for processing blood flow video data obtained using the magnifying endoscope, and (A) the magnifying endoscope shoots a blood flow video of the gastric subepithelial microvessel and transmits the blood flow video to the blood flow video data processing unit, and (B) after receiving the blood flow video, the blood flow video data processing unit performs the following data processing (B1) to (B5): (B1) processing of decomposing the obtained blood flow video into frames, (B2) processing of removing a translation component by comparing an image of frame 1 and an image of subsequent frame 2, (B3) processing of calculating a difference in a red component between the images from which the translation component has been removed, (B4) processing of segmenting a part for which the difference in the red component has been calculated, and (B5) processing of calculating a segment size of obtained segment data.
