Abstract:
1. An endoscope apparatus comprising: an image processing portion for performing image processing on a signal of an image picked up by an image pickup device installed in a distal end portion of an endoscope insertion portion and generating an endoscope image; a graphics generating portion for generating a gravity direction graphic to be displayed with the endoscope image in which when the distal end portion is in a normal position, a gravity direction mark indicating a gravity direction and a zenith direction mark indicating a direction opposite to the gravity direction are placed at positions opposing each other on a circumference of the gravity direction graphic; a control portion for, according to the position of the distal end portion, controlling the graphics generating portion to generate the gravity direction graphic; an image combining portion for combining the gravity direction graphic in a predetermined position of the endoscope image; a distal end optical system that is detachably attached to the distal end portion, the distal end optical system comprising an identification portion; and an optical system identification portion for identifying a class of the distal end optical system based on the identification portion, wherein the control portion
