1. An imaging device including a monitor and an imaging unit, the imaging device comprising:
a processor:
a ring operation member that is rotatably operable;
a detector that is configured to detect rotation of the ring operation member as a signal; and
a communication unit that is configured to communicate the signal detected by the detector to a wearable device, the signal being used for display control of the wearable device,
wherein the signal comprises at least one of a signal associated with a setting of imaging conditions of the imaging unit, or a signal associated with a display setting of an image displayed on the monitor,
wherein the signal comprises a signal indicating an operation amount of the ring operation member, and
the processor is configured to:
acquire an image to be displayed on the monitor, wherein the image includes magnification changing operation-related information related to an amount of change in magnification with respect to an operation amount of the magnification changing operation performed in an imaging at an imaging apparatus that has captured the image,
determine an amount of change in a display magnification of the image based on the operation amount indicated by the signal, and
match the amount of change in the magnification with respect to the operation amount of the magnification changing operation performed in the imaging, to an amount of change in magnification with respect to an operation amount of the ring operation member when changing the display magnification of the image, based on the magnification changing operation-related information.
