Patent Images
1. An endoscope comprising:
- an objective optical system which is insertable into a body;
an image taking means having an image taking range which takes an image formed by the objective optical system and outputs an image signal representing the image, the image taking range including a restoration range and a residual range; and
an image processing means which performs image restoration processing on a part of the image signal corresponding to the restoration range, but not on a part of the image signal corresponding to the residual range.

Abstract
An endoscope includes an objective optical system which is inserted into a body and an image taking device which takes an image formed by the objective optical system and outputs an image signal representing the image. An image restoration processing is carried out on a part of the image signal corresponding to a predetermined range in the image taking range of the image taking device.

10. An endoscope comprising:
-
an objective optical system which is insertable into a body; an image taking means having an image taking range which takes an image formed by the objective optical system and outputs an image signal representing the image, the image taking range including a restoration range and a residual range; a distance measuring means which detects the distance between (1) each point on a part of the body within the image taking range of the image taking means and (2) the objective optical system, the points on the part of the body which are greater than a predetermined distance from the objective optical system defining the restoration range of the image taking range; and an image processing means which performs image restoration processing on a part of the image signal corresponding to the restoration range, but not on a part of the image signal corresponding to the residual range. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
