1. A measuring endoscope apparatus comprising: an imaging section that images a subject to generate an image; a display that displays the image; a measuring section that measures the dimensions of the subject based on the image; an input section that inputs a first calibration data of a calibrator used when the measuring endoscope apparatus is adjusted; and a recording section that associates a second calibration data of the measuring endoscope apparatus including a first value obtained when the measuring section measures the calibrator based on a calibrator image obtained when the imaging section images the calibrator, and the first calibration data, and a second value obtained when the measuring section measures a measurement object based on an object image of the measurement object that is different from the calibrator, with the object image and records an associated data on a recording medium.
