Abstract: An endoscope system includes an image acquisition section, an attention area setting section, and a dimming control 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 dimming control section performs a dimming control process that controls the intensity of illumination light based on the attention area set by the attention area setting section.

Abstract: An endoscope apparatus including an imaging section that includes a phase difference detection element for implementing phase detection autofocus, and acquires a captured image; a phase difference calculation section that calculates a phase difference based on a signal output from the phase difference detection element; a lens position selection section that selects a lens position that is either a near point-side lens position or a far point-side lens position based on the phase difference, the near point-side lens position and the far point-side lens position being discrete lens positions set in advance; a driver section that changes a lens position of the imaging section to the lens position selected by the lens position selection section; and a control section that controls an intensity of illumination light that is applied to an object. The lens position selection section determines whether or not the intensity is smaller than a given threshold value when the phase difference calculation section cannot detect the phase difference, selects the near point-side lens position when the lens position selection section has determined that the intensity is smaller than the threshold value, and selects the far point-side lens position when the lens position selection section has determined that the intensity is larger than the threshold value.

Abstract: A reflected light image and a fluorescent light image of an observed region are acquired with an imaging system. A gradation level of the reflected light image is set on the basis of a feature value of the acquired reflected light image. The focus of the imaging system is controlled in accordance with the set gradation level. The fluorescent light image is corrected using a focus-controlled reflected light image of the observed region. Accordingly, the image of an object in the observed region from which the fluorescent light is generated is sharpened.

Abstract: A focus control device in an endoscope system, implements an autofocus operation in an appropriate state by setting a focus mode of an imaging optical system. The focus control device includes a focus control section that controls a focus of an imaging optical system that includes at least a zoom lens that adjusts an optical magnification, and sets a focus mode of the imaging optical system, and an image acquisition section that acquires an image through the imaging optical system, the focus mode including a fixed focus mode and an autofocus (AF) mode, and the focus control section switching the focus mode between the fixed focus mode and the AF mode corresponding to whether the zoom lens is positioned on a wide-angle side or a telescopic side relative to a reference point that is situated between a wide-angle end and a telescopic end.

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.
