The image processing device performs image processing using image data generated by an image generating device, and image generation record information associated with the image data where the image generation record information includes at least operating information about the image generating device at the time of generation of the image data. A picture quality adjuster is able, when the image generation record information includes subject brightness information relating to the brightness of a subject at the time of generation of the image data, to adjust the picture quality of the image data using the subject brightness level derived from the subject brightness information.
