AI summary

An imaging support device includes a processor, and a memory that is connected to or incorporated in the processor, in which the processor is configured to derive information related to inclination of an imaging apparatus with respect to a revolution mechanism that enables the imaging apparatus to revolve about each of a first axis and a second axis intersecting with the first axis as a central axis, based on a time series change in revolution angle of the imaging apparatus, the inclination of the imaging apparatus being inclination in a rotation direction about a third axis intersecting with the first axis and the second axis as the central axis, and adjust a position of a captured image obtained by imaging performed by the imaging apparatus based on the information related to the inclination.
