IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND ENDOSCOPE SYSTEM

摘要

Provided are: an image processing device and image processing method for calculating a diagnosis support parameter based on the condition of a blood vessel to be observed; and an endoscope system. This image processing device (65) is provided with: an image acquisition unit (81) that acquires an endoscopic image; a blood vessel extraction unit (82) that extracts a blood vessel using the endoscopic image; a blood vessel information calculation unit (83); and a blood vessel parameter calculation unit (84). The blood vessel information calculation unit (83) calculates a plurality of pieces of blood vessel information that include at least two from among: the number of blood vessels; number of branches; branch angle; distance between branch points; number of intersections; thickness; change in thickness; complexity of change in thickness; length; spacing; depth based on mucous membrane; height difference; inclination; area; density; contrast; color; change in color; sinuosity; blood concentration; oxygen saturation; proportion of arteries; concentration of administered dye; travel pattern; and blood flow rate. The blood vessel parameter calculation unit (84) calculates a blood vessel parameter by carrying out a calculation using the pieces of blood vessel information.
