Abstract:
An evaluation method for evaluating the performance of an image stabilization function of an imaging apparatus includes: a first imaging step of imaging an object, with the image stabilization function being ON and the imaging apparatus being vibrated; a second imaging step of imaging the object, with the imaging apparatus being static; a first calculation step of calculating a first shutter speed based on the image taken in the first imaging step, and calculating a first evaluation value based on the first shutter speed and a reference shutter speed; a second calculation step of calculating a second evaluation value based on the images taken in the first and second imaging steps; and an evaluation step of calculating an evaluation value of the performance of the image stabilization function of the imaging apparatus, based on a result of subtraction of the second evaluation value from the first evaluation value.
