Abstract: An endoscopic calibration system that calibrates an endoscope, includes: an imaging part that acquires an image by an optical system in which an optical adapter and a scope of the endoscope are combined; a parameter measurement part that measures a first parameter indicating optical characteristics of an optical system in which a first scope and a first optical adapter are combined, a second parameter indicating optical characteristics of an optical system in which the first scope and a second optical adapter are combined, and a third parameter indicating optical characteristics of an optical system in which the second scope and the first optical adapter are combined; and a parameter estimation part that estimates a fourth parameter indicating optical characteristics of an optical system in which the second scope and the second optical adapter are combined using the first parameter, the second parameter, and the third parameter.

Abstract: A measurement method includes a generation step, a region detection step, an image display step, a point input step, and a measurement step. Three-dimensional image data including three-dimensional coordinates of two or more points on a subject are generated in the generation step. Two or more feature regions on the subject are detected on the basis of the three-dimensional image data in the region detection step. An image of the two or more feature regions is displayed on a display in the image display step. A point on the subject is accepted through an input device in the point input step. A size of the subject is measured on the basis of three-dimensional coordinates of two or more points on the subject.

Abstract: An endoscope apparatus includes: an image processing portion that performs image processing on a signal of an image picked up by an image pickup device provided at a distal end portion of an endoscope insertion portion to generate an endoscope image; a gravity direction detecting portion that detects information about a gravity direction of the distal end portion; a gravity signal processing portion that performs predetermined signal processing on a signal of the information about the gravity direction detected by the gravity direction detecting portion to detect gravity information. The recording medium reading/writing portion of the endoscope apparatus stores data of the endoscope image generated by the image processing portion and data of the gravity information detected by the gravity signal processing portion in two AVI files and records the files on a recording medium.

Abstract: An endoscope apparatus includes an image processing portion for performing image processing on a signal of an image pickup picked up by an image pickup device installed in a distal end portion of an endoscope insertion portion to generate an endoscope image, a gravity direction detecting portion for detecting information about a gravity direction of the distal end portion, a gravity signal processing portion for performing predetermined signal processing on a signal of the information about the detected gravity direction to generate gravity information, a graphics generating portion for generating an indicator indicating the gravity direction based on the gravity information, and an image combining portion for combining the endoscope image and the indicator and outputting combined image information to a display apparatus. The graphics generating portion changes a display form of the indicator indicating the gravity direction according to the gravity direction.
