To prevent an increase in a data storage space required for image restoration processing, a non-transitory computer-readable storage medium according to the present invention stores a process for causing an information processing apparatus to execute a method including acquiring identification information for identifying an optical transfer characteristic for restoring an image, acquiring the optical transfer characteristic identified based on the identification information from a storage unit storing a first optical transfer characteristic commonly usable for first and second captured images captured under different imaging conditions and a second optical transfer characteristic usable for a third captured image, and generating a restored image with use of the acquired optical transfer characteristic.
