An endoscope system capable of easily measuring a size of a subject is provided. In the endoscope system, since an index figure indicating an actual size of a specific region of a test object is displayed together with an image of the subject, a user can measure the specific region easily by comparing the specific region with a marker. Since the size of the index figure is set in accordance with a spot position, there is no need for distance measurement, a device configuration is simple, and measurement can be quickly and easily performed. In addition, a specific value of the 'actual size' can be set in accordance with conditions, such as the type of test object and the purposes of measurement. Additionally, an affected region can be the specific region in a case where the test object is a living body.

Endoscope system

Provided are a measurement support device, an endoscope system, a processor for an endoscope system, and a measurement support method capable of easily and highly accurately measuring the size of a subject. In the measurement support device related to one aspect of the invention, the position of a spot by measurement auxiliary light is measured, and information indicating the actual size of a subject is acquired on the basis of the measurement result to create and display a marker. Moreover, an optical axis of the measurement auxiliary light has an inclination angle that is not 0 degrees with respect to an optical axis of the imaging optical system in a case where the optical axis of the measurement auxiliary light is projected on a plane including the optical axis of the imaging optical system.

An auxiliary measurement light-emitting unit emits auxiliary measurement light that is planar light including at least two first feature lines. A taken image obtained through the imaging of a subject includes an intersection curve and at least two first spots that are formed at positions corresponding to first feature lines on the intersection curve. Measurement information representing the actual size of the subject is displayed in the taken image by using the positions of the first spots.

Endoscope system and method of driving endoscope system

The invention aims at providing a measurement support device, an endoscope system, and a processor for an endoscope system capable of displaying an accurate indicator with a simple configuration. In a measurement support device related to one aspect of the invention, the coordinates of a spot, and coordinates of points indicating an actual size of a measurement target in a subject and indicating a circular marker distorted in accordance with distortion aberration of an imaging optical system are stored in association with each other in a storage unit, the coordinates of the points indicating the circular marker are acquired with reference to the storage unit on the basis of the measured coordinates of the spot, and the circular marker is displayed on the basis of the acquired coordinates. Thus, the distance measurement is unnecessary, the configuration is simple, and the processing load is low. Additionally, since the circular marker is displayed in the vicinity of the spot (for example, centering on a spot position), there is little deviation between the spot position and a marker position, the circular marker is accurate as an indicator. Additionally, since the indicator is not widely displayed, there is little processing load.
