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.

Abstract: A computer program or the like having high ability of detecting a lesion is provided. A computer program causes a computer to execute processing of: acquiring an image captured by an endoscope; inputting the image captured by the endoscope to a first recognizer that recognizes a lesion section on the basis of the image and a second recognizer that recognizes the lesion section with higher recognition accuracy than the first recognizer on the basis of the image; acquiring provisional information including a recognition result recognized by the first recognizer; outputting an image including the acquired provisional information; acquiring confirmation information for the provisional information including a recognition result recognized by the second recognizer; and outputting an image including the acquired confirmation information.
