Abstract: A high-resolution and compact endoscopic apparatus is provided. The endoscopic apparatus comprises: an insertion unit configured to be inserted into a body cavity and guide light from an object; an illumination device attached to the insertion unit and illuminating the object; and an imaging device comprising 8K-level or higher-level pixels arranged in a matrix form. The imaging device receives light reflected from the object and guided through the insertion unit and outputs image data of the object. The pitch of the pixels of the imaging device is equal to or larger than the longest wavelength of illumination light emitted from the illumination means.

Abstract: Provided is an endoscope system wherein, when a trigger signal generating unit of an endoscope (10) generates a zoom-in or zoom-out trigger signal, a control device (40) identifies the fixation point of an operator in a display image of a display device (30) on the basis of a relationship between a detection signal from a sensor in polarized glasses (50) and a detection signal from a sensor in the display device (30) at the time of generation of the trigger signal, and zooms in or zooms out the peripheries of the fixation point.

Abstract: An endoscope device is provided to comprise an insertion unit configured to be inserted into a body cavity and guide light from an object, an illumination device attached to the insertion unit and illuminating the object, and an imaging device having an imaging element provided with 8K-level or higher-level pixels. The imaging element receives light reflected from the object and guided by the insertion unit and outputs imaging signals of the object. The insertion unit and the illumination device may be attached to the imaging device. The imaging device may be grasped and carried by a human hand. The imaging device has a mounting part incorporating the imaging element and a grasping part. The cross-sectional area of the mounting part perpendicular to an optical axis is equal to or larger than the cross-sectional area of the grasping part perpendicular to the optical axis.
