Abstract
A theoretical motion blur amount is calculated. A static state image is acquired. For each of the plurality of shutter speed values, a bokeh amount at the boundary between different color areas in each of a plurality of the static state images that have been acquired is measured as a bokeh offset amount. A vibrated state image while the camera is being vibrated with its image stabilization function being ON is acquired. A bokeh amount at the boundary between different color areas in each of the plurality of vibrated state images that have been acquired is measured as a measured comprehensive bokeh amount. And an evaluation value indicating the performance of the image stabilization function of the camera is calculated based on the theoretical motion blur amount, the bokeh offset amount, and the measured comprehensive bokeh amount.
