Abstract: In an image processing apparatus that is capable of setting desired image processing conditions for each of images that have been shot, an image of interest for which number of prints is to be set is specified and it is determined whether image processing conditions have been set for the specified image of interest. If image processing conditions have not been set for the specified image of interest, a number of prints for the image of interest is allowed to be set. If setting of number of prints has been allowed, then the setting of number of prints is accepted and the set number of prints is stored in correlation with the image of interest.
