Abstract: An autofocus control device includes a processor. The processor performs an image acquisition process of acquiring an object image captured by an imaging section, a treatment determination process of determining whether or not treatment is being performed based on the object image, a focus evaluation area setting process of setting either a preset area or a treatment area set based on the object image, as a focus evaluation area in the object image based on a determination result of the treatment determination process, and a focus control process of performing focus control of the imaging section based on a focus evaluation value of the focus evaluation area.

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 comprises a processor comprising hardware. The processor is configured to implement a motion amount calculation process and a focus control process. The processor implements the motion amount calculation process that calculates a plurality of local motion amounts, calculates a correlation between each of the plurality of local motion amounts and a peripheral local motion amount, and calculates the relative motion amount based on a local motion amount among the plurality of local motion amounts that has the correlation higher than a given correlation. And the processor implements the focus control process that calculates a cumulative motion amount by accumulating the relative motion amount over N frames (wherein N is a natural number equal to or larger than 3), and causes the imaging section to perform a focus operation when it has been determined that the cumulative motion amount is larger than the first threshold value.
