1. An image processing apparatus comprising: a tag specifying information acquisition unit for acquiring first tag specifying information that specifies tag information of an image; a first image processing unit for acquiring, from among items of second tag specifying information from an image processing table that stipulates a plurality of corresponding relationships each of which is a corresponding relationship among three items which are second tag specifying information, processing content that defines processing to be applied to the image and number of implementations of processing of the processing content, second tag specifying information that matches the first tag specifying information acquired by said tag specifying information acquisition unit, reading processing content, which corresponds to the acquired second tag specifying information, from the image processing table, and subjecting the image to processing defined by the read processing content; and a first implementation-count increasing unit for increasing, from among the numbers of implementations stipulated in the image processing table, the number of implementations corresponding to the processing content that defines the processing implemented by said first image processing unit.
