Abstract: A bar is displayed in a second region. In an undetected state in which a region of interest is not detected, the length of the bar is 0, and when the undetected state transitions to a detected state in which the region of interest is detected, the bar increases in length over time. In addition, when the detected state transitions to the undetected state, display of the bar is continued with the length fixed. Thus, even in the undetected state, it is known that the region of interest has been previously detected. In addition, even in the undetected state, the region-of-interest detected duration is known from the length of the bar.

Abstract: A remaining time calculation unit calculates, based on a notification waiting time indicating a time from when a feature region is recognized to when a notification of a recognition result of the feature region is started and a count time counted by a time count unit, a remaining time until the notification of the recognition result of the feature region is provided. A display control unit displays on a monitor remaining time notification information obtained based on at least the remaining time.

Abstract: An endoscope system and an operation method therefor in which information regarding a residual liquid is obtained to efficiently remove the residual liquid are provided. On the basis of image signals in a plurality of wavelength ranges, baseline information that is information regarding a light scattering characteristic or a light absorption characteristic of an observation target and that does not depend on specific biological information is calculated. A baseline correction value for adjusting the baseline information to reference baseline information that is a reference for evaluating the baseline information is calculated. From the baseline correction value, residual liquid information regarding a residual liquid included in the observation target is calculated.

Abstract: If zoom magnification falls within an optical-zoom application scaling range of zoom magnifications Z1 to Z2, image data that has been enlarged by a zoom lens is recorded on a recording medium. If zoom magnification falls within an electronic-zoom application scaling range of zoom magnifications Z2 to Z3, the image data is subjected to super-resolution processing, super-resolution image data and image data that has not been subjected to super-resolution processing are combined by weighting processing executed such that the higher the zoom magnification, the greater the weight assigned to the super-resolution image data, and the resultant image data is subjected to electronic zoom processing and then recorded. If zoom magnification exceeds Z3, the super-resolution image data is recorded upon being subjected to electronic zoom processing.
