Abstract: The present disclosure provides an image processing device, an imaging apparatus, an image processing method, and an image processing program capable of accurately extracting an abnormal region of a subject from an image. In the image processing device according to one aspect of the present invention, a processor generates a first mask image showing a first region where an abnormality exists on a surface of a subject and a second region including a region where an abnormality exists inside the subject, based on a visible image and a first near-infrared image, acquires a second near-infrared image of the subject captured with light in a second wavelength range in a state where the subject is held in focus with the light in the second wavelength range, and extracts an abnormal region in the first region and the second region based on the first mask image and the second near-infrared image.

Abstract: An imaging support method includes acquiring a focal length of an imaging apparatus, detecting a subject image position of a target subject image showing a target subject in a captured image obtained by capturing an imaging region including the target subject by the imaging apparatus, and performing registration control for setting the detected subject image position to a specific position in the captured image by increasing a ratio of application of an image region movement component compared to a lens moving mechanism in a case where the acquired focal length is greater than or equal to a threshold value, and increasing a ratio of application of the lens moving mechanism compared to the image region movement component in a case where the focal length is less than the threshold value.

Abstract: A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to each of a first operation recommendation condition under which an operation of a mechanical correction unit that corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended, and a second operation recommendation condition under which an operation of an electronic correction unit that corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element is recommended. The operation control unit performs a control for selectively operating the mechanical correction unit and the electronic correction unit at a subsequent time of a plurality of consecutive times depending on the first operation recommendation condition, the second operation recommendation condition, and a plurality of related amounts that are the related amounts acquired by the acquisition unit and correspond to the plurality of consecutive times.
