Endoscope apparatus and program

An endoscope apparatus comprising:

• an electronic endoscope that picks up a measurement object and produces a picked-up-image signal;
• an image-processing unit that produces an image signal based on the picked-up-image signal;
• and
• a measurement processing unit that measures the measurement object based on the image signal;
• wherein the measurement processing unit includes:
• a reference point-designating unit that designates two reference points on the measurement object;
• an approximate-outline calculating unit that calculates an approximate outline by approximating an outline of the measurement object based on the two reference points;
• and
• a loss-composing points-calculating unit that calculates loss-composing points that constitute a loss outline formed on the measurement object based on the two reference points and the approximate outline;
• and
• wherein the two reference points are designated such that the loss formed on the measurement object is interposed between the two reference points.

A loss-displaying method using an endoscope apparatus, the endoscope apparatus comprising an electronic endoscope that picks up a measurement object and produces a picked-up-image signal, an image-processing unit that produces an image signal based on the picked-up-image signal, and a measurement processing unit that measures the measurement object based on the image signal, the method being implemented by the endoscope apparatus to perform functions comprising:

• displaying two reference points on the designated measurement object;
• displaying an approximate outline by approximating an outline of the measurement object;
• and
• displaying a loss formed on the measurement object and calculated based on the two reference points and the approximate outline;
• wherein the two reference points are designated such that the loss formed on the measurement object is interposed between the two reference points.
