1. A measuring endoscope apparatus comprising:
- a stereo optical endoscope that provides a plurality of observation fields from one position of the head of the stereo optical endoscope, the stereo optical endoscope comprising an image pickup unit;
an image processing unit that receives an image pickup signal from the image pickup unit, the image processing unit generating an image signal from the image pickup signal;
a control unit comprising a measurement processing unit, the measurement processing unit receiving the image signal from the image processing unit, the measurement processing unit performing a measurement process based on the image signal;
a display unit that receives an output image from the control unit, the display unit displaying the output image;
an observation image capturing unit that captures an observation image of an object;
a distance measuring processing unit that calculates an object distance from a distance measuring point designated on the observation image to an image pickup surface of the image pickup unit, the calculation being made based on the observation image that is captured at a time; and
a measurable range display unit that displays an indication related to the object distance.
