Abstract
In an image capturing system, an image capturing apparatus transmits information indicating set capturing conditions to an information processing apparatus. The information processing apparatus obtains a recovery filter corresponding to predetermined capturing conditions based on the information, and transmits the recovery filter to the image capturing apparatus. Upon receiving the recovery filter corresponding to the predetermined capturing conditions from the information processing apparatus, the image capturing apparatus stores the filter in a storage device. Upon obtaining an image signal by capturing, the image capturing apparatus performs recovery processing by applying the received recovery filter to the image signal.
