1. An evaluation method of an image stabilization effect of an imaging device, the evaluation method comprising:
calculating an evaluation value of the image stabilization effect on the basis of shutter speed values in case of which each of a reference shake amount theoretically calculated on the basis of a shake waveform applied to the imaging device and a measured shake amount calculated using an image captured in a state in which the imaging device is vibrated becomes a specified shake amount; and
setting the specified shake amount,
wherein the setting comprises:
calculating an image deterioration amount of the imaging device caused by something other than a shake from the outside; and
selecting a determination level that defines the specified shake amount from a plurality of determination levels having different shake amounts on the basis of the image deterioration amount.
