Abstract: An endoscope system includes a light source configured to generate either one of first illumination light and second illumination light, an image pickup apparatus configured to obtain an image by picking up an image of an object, and a processor. The processor is configured to make an instruction to set an observation mode of the endoscope system at either one of a first observation mode and a second observation mode, detect an observation state at a time of observing the object based on a feature value calculated from pixel values included in pixels forming a first image, and invalidate an instruction to set the observation mode of the endoscope system at the second observation mode when the observation state at the time of observing the object is not an appropriate observation state.

Abstract: A scanning type endoscope includes a light guide section configured to guide illumination light, a ferrule provided along the light guide section, an actuator configured to vibrate the ferrule to thereby swing a distal end of the light guide section, a cylindrical member configured to include a space containing the light guide section, the ferrule and the actuator and being provided along the light guide section, and a damping section configured to fix the ferrule to the cylindrical member and absorb vibration of the ferrule, in which the damping section is formed of a ferrule holding member configured to hold a proximal end of the ferrule and a ring-shaped member configured to fix the ferrule holding member to the cylindrical member, be disposed near a joint in the cylindrical member connected to holding member and be made of a material that absorbs vibration of the ferrule.

Abstract: A scanning endoscope includes: a light guide portion configured to guide an illuminating light that is emitted from a light source portion and irradiate an object with the illuminating light; an actuator configured to drive so as to cause a distal end of a light guide portion to scan, in order to scan the guided illuminating light over an object; a holding portion configured to hold the actuator; a rigid tubular member having a space that encloses the light guide portion, the actuator and the holding portion; and a connection portion that is interposed between the tubular member and the holding portion, and is configured to hold the holding portion at a prescribed position within the tubular member and to change shape in a circumferential direction that takes a longitudinal direction of the light guide portion as an axis when the tubular member or holding portion receives a force.

Abstract: An endoscope system includes a light source apparatus configured to generate first/second illumination light, an image pickup apparatus, a switching instruction device configured to be able to set one of a first observation mode in which an image obtained by image pickup of an object illuminated with the first illumination light is displayed and a second observation mode in which an image obtained by processing a color/pattern of an image obtained by image pickup of the object illuminated with the second illumination light is displayed and a processor configured to calculate a feature value indicating movement of a distal end portion of an endoscope and disable an instruction for setting the second observation mode when the feature value is equal to or higher than a predetermined threshold.

Abstract: An endoscope apparatus includes a display control system configured to calculate at least one index indicating a degree of abnormality of an object, according to a color included in an acquired object image, and to generate a display image in which the at least one index is identifiably displayed based on a predetermined threshold value that is set independently of the object image.

Abstract: A scanning endoscope includes: an optical fiber that guides light emitted from a light source section, and emits the light from a distal end; an actuator that expands and contracts to scan with the light emitted from the distal end of the optical fiber; a ferrule that transmits, to the optical fiber, force corresponding to the expansion and contraction of the actuator; a ferrule holding part that holds the ferrule; a lens holding part that is formed of a cylindrical member provided outside the optical fiber along the optical fiber, and holds a lens, the lens receiving the light emitted from the distal end of the optical fiber; and an absorption part that absorbs vibration, in a longitudinal direction of the cylindrical member, of at least one of the ferrule holding part and the lens holding part.
