摘要： An endoscope includes a connector for connecting a movable body and a long member. The connector includes: an open-close member having a distal end portion and a proximal end portion which are opened or closed by swinging about a predetermined fulcrum, the proximal end portion having a holding portion which holds the long member when the proximal end portion is closed, the distal end portion having an engaging portion which projects outwardly in a radial direction of the distal end portion and is engageable with an inner side of the movable body; and a locking member which moves in a longitudinal direction outwardly in a radial direction of the open-close member, and locks the proximal end portion of the open-close member and the movable body with each other in a state where the long member is held.

摘要： A stereoscopic endoscope apparatus includes: an image pickup device configured to pick up optical images for a right eye and a left eye; a similarity degree determination portion configured to receive input of an image signal for the right eye and an image signal for the left eye outputted from the image pickup device, and calculate a similarity degree between the image for the right eye and the image for the left eye; and an image signal output portion configured to switch and output a three-dimensional image signal formed of the image signal for the right eye and the image signal for the left eye and a two-dimensional image signal formed of either one of the image signal for the right eye and the image signal for the left eye, based on the similarity degree calculated by the similarity degree determination portion.
