Imaging support device that performs registration control for setting a detected subject image position, imaging support system, imaging system, imaging support method, and program

An imaging support method comprising:

• acquiring a focal length of an imaging apparatus which includes a lens and an imaging element and includes a lens moving mechanism which moves the lens in a direction intersecting with an optical axis of the lens, and an image region movement component which moves a region of a captured image in the imaging element in the direction intersecting with the optical axis, the captured image being stored in a memory that is incorporated in or connected to a processor;
• detecting a subject image position of a target subject image showing a target subject in the captured image based on the captured image stored in the memory by capturing an imaging region including the target subject by the imaging apparatus;
• 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 the image region movement component compared to the 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, and
• causing the lens moving mechanism to correct shake caused by vibration applied to the imaging apparatus in a case where the focal length is greater than or equal to the threshold value, and causing the image region movement component to correct the shake in a case where the focal length is less than the threshold value.

A non-transitory computer-readable storage medium storing a program executable by a computer to perform a process comprising:

• acquiring a focal length of an imaging apparatus which includes a lens and an imaging element and includes a lens moving mechanism which moves the lens in a direction intersecting with an optical axis of the lens, and an image region movement component which moves a region of a captured image in the imaging element in the direction intersecting with the optical axis, the captured image being stored in a memory that is incorporated in or connected to a processor;
• detecting a subject image position of a target subject image showing a target subject in the captured image based on the captured image stored in the memory by capturing an imaging region including the target subject by the imaging apparatus;
