Abstract
The present invention provides an evaluation method for more precisely determining the blur correction capability of an image capturing apparatus. The method for evaluating the blur correction effect of the image capturing apparatus comprises acquiring a first change amount for each image capture from a predetermined captured number of subject images that have been captured by an image capturing apparatus that has been vibrated; dividing the predetermined number of captured images into a plurality of segments, and calculating a second change amount for each segment by performing statistical processing on the first change amounts in each of the plurality of segments; determining the largest second change amount from among the second change amounts in each segment to serve as a third change amount; and performing evaluation of the blur correction effect based on the third change amount.
