Apparatus for reducing network patterns from the image of a fiber scope

摘要

An optical image is formed on one end surface of an image guide formed Of a fiber bundle by an objective optical system provided in a tip section at the tip of an elongate insertable section, is transmitted to the other end surface and is photoelectrically converted by an imaging device together with the pattern of the fiber bundle on the other end surface to be an image signal. This image signal is separated by a region separating circuit into a fiber bundle light transmitting region and another non-representative region. The image data of the non-representative region are processed to be replaced with other image data by an image replacing circuit to produce an image having had the network pattern of the fiber bundle reduced.
