Abstract: An image processing device extracts a candidate region and region information of the cell nucleus from a cell image (S20), judges whether or not to correct the candidate region of the cell nucleus on the basis of the region information of the cell nucleus, and corrects the candidate region of the cell nucleus on the basis of the judged result (S40).

Abstract: An optical measurement device provided with: a first adjustment optical device for collecting radiation light received by a probe that emits measurement light to a measurement target and receives radiation light radiated from the measurement target, and for emitting the radiation light toward the spectroscope for dividing the radiation light; a detection section for detecting a light intensity distribution of the radiation light; a movement part for moving the first adjustment optical device in a light axis direction of the radiation light and on a plane perpendicular to the light axis direction of the radiation light; and a control section for controlling the movement part. The first adjustment optical device is moved in the light axis direction of the radiation light and on the plane on a basis of a detection result of the detection section such that a reception amount of the radiation light increases.

Abstract: Provided is a probe and a measurement system which uses the probe. According to one implementation, the probe includes a radiated-light measurement optical system and an oblique-viewing imaging device. The radiated-light measurement optical system irradiates illumination light onto a measurement target region on a biological tissue. The oblique-viewing imaging device has an angular field ? and a forward tilt angle ? defined by a center axis of a field of view and a radial direction of the probe. The radiated-light measurement optical system has an optical element that determines a direction of emission of the illumination light, and a forward tilt angle ? is defined by the direction of emission and the radial direction of the probe. The oblique-viewing imaging device and the optical element are positioned such that the measurement target region lies within the angular field.
