Abstract: An authentication method for endoscope includes acquiring a first identification information stored in a first memory of the endoscope, acquiring a second identification information stored in a second memory of the endoscope, comparing the acquired first identification information with the acquired second identification information, and based on a result of the comparing, performing a first processing or a second processing.

Abstract: An endoscope includes an insertion portion configured to be inserted into a subject; a channel tube forming a first portion of a channel in the insertion portion, and a coil wound around at least a portion of the channel tube. The channel tube includes a first magnetic material, and the coil generates a magnetic field in response to a supplied electric current to magnetize the first magnetic material.

Abstract: An endoscope includes: an insertion portion formed along a longitudinal axis extending from a proximal end to a distal end; a light guide having an optical characteristic that enables transmitting lithotriptic light and illuminating light having respective wavelength bands that are different from each other, from the proximal end toward the distal end of the insertion portion; and a treatment instrument insertion channel provided in the insertion portion, the treatment instrument insertion channel extending from the proximal end to the distal end.

Abstract: An endoscope according to an embodiment of the present disclosure includes an insertion portion configured to be inserted into a subject. A channel is provided in the insertion portion, the channel receiving an accessory. A plurality of first guides is spaced apart at intervals in the channel, the plurality of first guides configured to guide the accessory along a longitudinal axis of the insertion portion.

Abstract: An information processing apparatus includes a processor. The processor acquires a picked-up image, creates metadata concerning the picked-up image, records an image file including the picked-up image and the metadata, and creates, as the metadata, information concerning the picked-up image with a table format in a first region in the image file and creates the information concerning the picked-up image with unstructured data in a second region extended by the information recorded by the table format in the image file.
