Title: ENDOSCOPE SYSTEM, IMAGE PROCESSING DEVICE, AND IMAGE PROCESSING DEVICE OPERATION METHOD
Abstract:
Provided are an endoscope system, an image processing device, and an image processing device operation method that make it possible to estimate the absolute blood vessel depth of blood vessels depicted in an endoscopic image. An endoscope system that comprises: a light source unit that generates a plurality of types of illumination light that have different wavelength bands; an imaging sensor that captures images of an observation target as irradiated with any one of the plurality of types of illumination light; a blood vessel shape determination unit (84) that, on the basis of an image signal obtained from the imaging sensor, determines a shape pattern for blood vessels of interest that are at least one portion of the blood vessels in a captured image of the observation target; and a blood vessel depth estimation unit (85) that estimates the blood vessel depth of the blood vessels of interest on the basis of the shape pattern.
