Abstract: An optical film includes a plurality of optical elements. In a case where a first reference line parallel to a film surface is extended in a horizontal direction from a first optical element, a second optical element adjacent to the first optical element is placed at a predetermined spacing in a direction forming a first angle with respect to the first reference line. A third optical element adjacent to the first optical element is placed at a predetermined spacing in a direction forming a second angle with respect to a second reference line orthogonal to the first reference line and parallel to the film surface. Another optical element is also placed at a predetermined spacing from an adjacent optical element in the direction forming the first angle, and is placed at a predetermined spacing from an adjacent optical element in the direction forming the second angle.

Abstract: An intubation apparatus includes an inserting section that has an elongated shape and is to be inserted from a mouth of a subject toward a target site. An intubation tube is formed to extend along a longitudinal direction of the inserting section and is advanceable and retractable with respect to the inserting section. An imaging section is placed at a tip end of the inserting section and takes an in vivo image of the body of the subject. A detecting section detects a target site from the in vivo image based on a feature amount of the target site that is preset. A notifying section is disposed integrally with or separately from the intubation apparatus and notifies an operator who operates the inserting section. A notification controller controls the notifying section to notify of information relating to the target site of the subject based on a result of the detection.
