The present invention provides a measuring endoscope apparatus which
includes an endoscope that photoelectrically converts an image of an
object to generate an imaging signal, a signal processing section that
processes the imaging signal to generate image data, a distance measuring
section that calculates an object distance based on a principle of
triangulation using the image data, and a display section that displays
the image of the object based on the image data. The measuring endoscope
apparatus further includes a measuring section that calculates a size of
the mark indicating a size of the object based on the object distance and
a view angle of the endoscope. The display section also displays a mark
along with the image of the object based on the image data.
