Document Type and Number:
WIPO Patent Application WO/2017/199926
Kind Code:
A1
Abstract:
Provided is a compact lightweight endoscope device which provides a high resolution image. This endoscope device 100 is provided with: an insertion section 110 adapted to be inserted into a body cavity and guiding light transmitted from an object; a lighting device 120 mounted to the insertion section 110 and lighting the object; and an image-capturing device having an image-capturing element which has 8K pixels or more arranged in a matrix array, receives light reflected from the object and guided through the insertion section 110, and outputs a signal of a captured image of the object, the image-capturing device allowing the insertion section 110 and the lighting device 120 to be mounted thereto, the image-capturing device being capable of being grasped and carried by a human hand. The image-capturing device 130 is configured such that the cross-sectional area of a mount section 135 incorporating the image-capturing element 131, the cross-sectional area being measured in a plane perpendicular to the optical axis, is equal to or greater than the cross-sectional area of a gripping section 136 grasped by a human hand for transportation purpose, the cross-sectional area being measured in a plane perpendicular to the optical axis.
