Abstract
An evaluation method of an image stabilization effect of an imaging device includes 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. The setting includes 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.
