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.

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 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.

Abstract: An imaging device includes a processor including hardware. The processor is configured to implement controlling a focus position of an objective optical system configured to form an image of a subject on an image sensor, acquiring L×N images per second captured by the image sensor, and combining acquired M images into one extended depth of field image to extend a depth of field, and outputting L extended depth of field images per second. The processor sets one of the M images as a reference image, performs positioning of the other image or images of the M images with respect to the reference image, and combines the thus positioned M images into the one extended depth of field image.
