Image processing apparatus, image processing method, image processing program, and non-transitory recording for calculating a degree-of-invalidity for a selected subject type

Abstract

With the object of making a user aware of the effect achieved by processing whose details and usage method he or she does not know and encouraging the use of such processing, the invention is an image processing apparatus including a subject recognition circuit that recognizes a subject type existing in an input image; a storage circuit that stores a plurality of processing instruction datasets that represent processing details for processing the input image; a processing instruction dataset obtaining circuit that obtains, from the storage circuit, processing instruction datasets which are predefined according to the subject type recognized by the subject recognition circuit; a processing instruction dataset determining circuit that calculates, for each of the obtained processing instruction datasets, a degree-of-invalidity indicating a degree to which the processing instruction dataset is not suitable for the input image and that selects a prescribed number of the processing instruction datasets for which the degrees-of-invalidity are less than or equal to a prescribed threshold; and an image processing circuit that performs processing of the input image using the prescribed number of selected processing instruction datasets.
