Abstract

An image processing device provided with: a plurality of sharpening circuits for enhancing frequency components that each differ with respect to an original image; an adjustment means for adjusting the signal level ratio of each image that has been sharpened by the respective sharpening circuits; and a generation means for generating an enhanced image by adding, at a prescribed ratio, the signalsof each image for which the signal level ratio has been adjusted.

Description

technical field [0001] The invention relates to an image processing device and an electronic endoscope system. Background technique [0002] An image processing apparatus is widely known that processes an original image to generate an enhanced image in which contours (edges) are enhanced. A specific configuration of such an image processing device is described, for example, in Japanese Unexamined Patent Application Publication No. 2002-183727 (hereinafter referred to as "Patent Document 1"). [0003] The image processing device described in Patent Document 1 is a device dedicated to contour enhancement of radiographic images. In the image processing device described in Patent Document 1, in order to obtain a radiographic image in which the contrast between brightness and darkness is enlarged and the contour is enhanced, a contour extraction process is performed by subtracting an unsharp image signal from an original image signal. Contents of the invention [0004] For ex...
