Abstract: A pattern quality management chart includes a chart substrate which is made of the same material as a substrate patterned by a first region having a predetermined affinity to a functional liquid for pattern formation and a second region having an affinity lower than the predetermined affinity, and at least one unit region group formed on the surface of the chart substrate. The unit region group includes a plurality of unit regions which are constituted of the first region surrounded therearound by the second region, and each of the unit regions is classified into either a compliant type unit region which has a shape and a size such that, when a predetermined amount of functional liquid is supplied to the unit region under predetermined supply conditions, the functional liquid does not overflow into the surrounding second region and the unit region is completely filled with the functional liquid, or a non-compliant type unit region which has a shape and a size such that part of the functional liquid overflows into the surrounding second region and/or a part of the unit region is not filled with the functional liquid. A plurality of unit regions include at least one compliant type unit region and at least one non-compliant type unit region.

Abstract: 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.

Abstract: 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.
