Abstract: An endoscope image processing device includes an image acquisition section, a distance information acquisition section, a concavity-convexity determination section that performs a concavity-convexity determination process that determines a concavity-convexity part of an object that agrees with characteristics specified by known characteristic information based on distance information and the known characteristic information that represents known characteristics relating to a structure of the object, a mucous membrane determination section that determines a mucous membrane area within the captured image, and an enhancement processing section that performs an enhancement process on the mucous membrane area based on information about the concavity-convexity part determined by the concavity-convexity determination process. The concavity-convexity determination section excludes a structure that is more global than a local concavity-convexity structure having a desired size from the distance information based on the known characteristic information to extract the local concavity-convexity structure having the desired size as the concavity-convexity part.

Abstract: An endoscope system includes an image acquisition section, an attention area setting section, and a scaling section. The image acquisition section acquires a captured image that includes an object image. The attention area setting section sets an attention area within the captured image based on information from the endoscope system. The scaling section performs a local scaling process that relatively enlarges the attention area as compared with another area.

Abstract: An endoscope apparatus includes a processor. The processor performs controlling a focus position of an objective optical system, acquiring images sequentially captured by an image sensor, and combining the images in N frames thus captured into a depth of field extended image in one frame. The processor controls the focus position such that focus positions at timings when the respective images in N frames are captured differ from each other. The processor combines the images in N frames that have been controlled to receive a constant quantity of light emission of illumination light or the images in N frames that have undergone a correction process to make image brightness constant, into the depth of field extended image.
