Abstract
An image quality adjuster adjusts luminance values of image data sing the image data generated by an image generating device, and image generation record information associated with the image data containing at least light emission information for a supplemental light source flash at the time of generation of the image data. Specifically, a decision is made based on the light emission information for the supplemental light source as to whether to execute an image quality adjustment process; and if a decision to do so, the image data is adjusted so as to reduce the maximum luminance value, which is the largest possible luminance value the image data may have.
