Abstract: A processor for an endoscope includes: an endoscopic image acquisition unit that acquires an endoscopic image of a patient from the endoscope; a virtual endoscopic image acquisition unit that acquires a virtual endoscopic image reconstructed on the basis of a three-dimensional medical image obtained by capturing an image of the patient in advance; a virtual endoscopic image reconstruction unit that reconstructs a corrected virtual endoscopic image that matches most with the endoscopic image on the basis of the degree of matching between the virtual endoscopic image and the endoscopic image; and a diagnosis support information output unit that outputs diagnosis support information based on a feature parameter corrected according to a correspondence between each pixel of the endoscopic image and a distance image obtained from the corrected virtual endoscopic image.
