Abstract: In a measurement support device according to an aspect, in a case where an indicator figure (marker) is displayed in the vicinity of a spot position, since the indicator figure is displayed in different aspects between a case where measurement of a specific region by the displayed indicator figure is effective and a case where measurement of a specific region by the displayed indicator figure is not effective, it is possible to easily grasp effectiveness of measurement by the display aspect of the indicator figure, and thus effective measurement can be easily performed. In addition, in the above-described aspect, since the indicator figure having a size set according to the position of the spot is displayed, distance measurement is not necessary, the configuration is simple, and the processing load is low. Further, since the indicator figure is displayed in the vicinity of the position of the spot, the difference between the spot position and the marker position is small and thus the indicator figure is accurate as an indicator, and since the indicator figure is not displayed in a wide range, the processing load is low.

Abstract: An endoscope includes an image pick-up-device at a distal-end-part of an insertion-part. The image pick-up-device includes a lens barrel holding an imaging lens; an image-sensor having a rectangular shape as an outer peripheral shape of an image reception surface on which imaging light incident via the imaging lens; and a sensor holder holding the image-sensor in a state where the image reception surface intersects a longitudinal direction of the insertion-part. The sensor holder has three independent wall-parts respectively covering three side surfaces of the image-sensor, and on an XY plane orthogonal to the longitudinal direction of the insertion-part, a gap length, in an X-axis direction on the plane between adjacent wall-parts of the three wall-parts and a gap length, in Y-axis direction, between the adjacent wall-parts are equal to each other. Additionally, the height of each of the three wall-parts is 1.5 times to 3 times the gap length.

Abstract: An object of the invention is to provide an endoscope system capable of easily measuring the size of a subject. In an endoscope system related to one aspect of the invention, 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.
