Endoscope apparatus and method of measuring subject

An endoscope apparatus, comprising:

• a display device that displays a first image and a second image, the first image and the second image being contained in image data of a subject captured by an imaging unit of the endoscope apparatus;
• a designation section that designates a first position on the first image in accordance with an instruction input through an input device;
• a position calculation section that calculates a second position on the second image, the second position corresponding to the first position on the first image;
• a display control section that, when the first position is designated, performs a control of displaying a first mark at the first position, subsequently displaying a third mark at a third position which is different from the first and second positions, and which does not correspond to the first position on the first image or the second position on the second image, and subsequently displaying a second mark at the second position;
• and
• a measurement section that performs measurement relating to the subject based on the first and second positions,
• wherein the display control section performs a control of displaying the third mark such that the third mark moves from the first position to the second position while passing through a plurality of the third positions, and controls a movement speed or a movement time of the third mark at a time of movement from the first position or the third position to the subsequent third position or the second position, based on a distance between a respective one of the plurality of the third positions and the first position or the second position.
