Abstract: An endoscope insertion observation apparatus includes a processor designed to perform functions including: detecting an insertion state of an insertion portion of an endoscope that is insertable into and extractable from a subject; determining whether or not the insertion portion has reached a second site in the subject from a first site in the subject and/or whether the insertion portion has reached the first site from the second site in the subject based on a detection result of the insertion state; and calculating a duration of movement of the insertion portion from the first site to the second site after determining that the insertion portion has reached the second site, or a duration of movement of the insertion portion from the second site to the first site after determining that the insertion portion has reached the first site.

Abstract: An endoscope insertion shape observation apparatus includes a processor, and the processor: detects a travelling direction of a first position detection member and a travelling direction of a second position detection member out of plural position detection members provided in an insertion portion inserted into a lumen of a subject, the first position detection member being provided on a distal end side of a bending portion of the insertion portion, the second position detection member being provided on a proximal end side of the bending portion; detects a stretch start timing in which the lumen starts stretching, based on detection results of the travelling directions and finds position coordinates of a predetermined position of the bending portion in the detected stretch start timing as a manual compression point; and causes a compression position display that indicates the position found as the manual compression point to be presented on a monitor.
