1. A processing device comprising:
at least one processor; and
a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, causes the at least one processor to function as:
a processing unit configured to derive pixel values corresponding to respective parameters based on a pixel value of one captured image among a plurality of images captured by a capturing device with different parameters and a parameter corresponding to a respective one of the plurality of captured images; and
an obtainment unit configured to obtain a characteristic in the capturing device based on a pixel value of respective one of the plurality of captured images and the derived pixel values,
wherein the parameter includes a shutter speed of the capturing device, an aperture value of the capturing device, or a sensitivity of the capturing device, and
wherein the processing unit derives the pixel values corresponding to the respective parameters based on a pixel value in a captured image whose pixel value is the largest among the plurality of captured images and the parameter corresponding to the respective one of the plurality of captured images.
