<p>Disclosed is an information processing device, program, information processing method, and information processing system that can obtain the focal distance for an image capture device easily and quickly. To achieve this aim, the information processing device is provided with: an image acquisition unit that obtains a standard image of a target object that is in a state where the spatial relationship with the imaging system is maintained, whereby said standard image is captured using image capture conditions with a known standard focal distance, and a reference image of said target object, whereby said reference image is captured based on image capture conditions with an unknown reference focal distance; and a focal distance acquisition unit that obtains the reference focal distance value by using image size information for the target object in the standard and reference images to perform arithmetic operations which scale the reference focal distance value.</p> |
