Abstract: A measuring endoscope apparatus captures a target of measurement, generates an original image, and performs a measurement based on the position of the measurement point on the original image. The apparatus can easily specify the measurement point with high precision, and realize high precision measurement. For example, the measurement point by a re-sampling image generated by moving sampling points by a spacing smaller than a pixel spacing of the original image obtained by capturing a target of measurement.

Abstract: An endoscope apparatus captures a subject, samples data at predetermined pixel spacing as an original image, and specifies a feature point in an original image, thereby performing a measurement. When a measurement point is specified in an enlarged image in an enlarged image generating process on the original image obtained by capturing an object to be measured, and when the specified point is to be long moved on the screen, it is moved with pixel spacing of the original image. When the feature point is specified in more detail, it is moved with pixel spacing finer than the pixel spacing of the original image, thereby efficiently performing an operation in a short time. Furthermore, by switching the above-mentioned settings, a measurement point can be more easily specified in a short time.
