EVALUATION METHOD, EVALUATION APPARATUS, COMPUTER READABLE RECORDING MEDIUM HAVING STORED THEREIN EVALUATION PROGRAM

摘要

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.

1. An evaluation method for evaluating the performance of an image stabilization function of an imaging apparatus, the evaluation method comprising:
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 detecting a motion blur amount based on an image taken in the first imaging step, calculating a first shutter speed that causes the detected motion blur amount to be a predetermined amount, and calculating, based on the first shutter speed and a reference shutter speed obtained from information relating to the vibration given to the imaging apparatus, a first evaluation value indicating a difference between the first shutter speed and the reference shutter speed; a second calculation step of calculating a second evaluation value indicating a difference in image quality between the image taken in the first imaging step and the image taken in the second imaging step; 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.
