Patent attributes
An endoscope apparatus includes an electronic endoscope that picks up a measurement object and produces a picked-up-image signal; an image-processing unit that produces a image signal based on the picked-up-image signal; and an measurement processing unit that undertakes measurement processing to the measurement object based on the image signal. 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 the outline of the measurement object based on the 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 reference points and the approximate outline. This enables loss size measurement upon designating two reference points, thereby reducing complex operations and improving operability.
