PROCESSOR FOR ELECTRONIC ENDOSCOPE AND ELECTRONIC ENDOSCOPIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/090044
Kind Code:
A1
Abstract:
One embodiment of the present invention pertains to a processor that is for an electronic endoscope and that is configured to acquire and process an image captured of a living tissue. This processor for an electronic endoscope is configured to acquire and process an image captured of a living tissue, and comprises: a light source device which emits illumination light onto a living tissue; a light source control unit which controls the intensity of the illumination light on the basis of information about the brightness of the captured image; an automatic gain control unit which determines a gain on the basis of the intensity of the illumination light and amplifies the captured image according to the determined gain; an edge enhancement processing unit which performs edge enhancement processing on the captured image amplified by the automatic gain control unit; and a control unit which controls the edge enhancement processing unit such that the level of enhancement in the edge enhancement processing becomes lower as the gain determined by the automatic gain control unit is greater.
