Abstract
An image retrieval apparatus comprises: a memory unit that stores image feature values; an acquisition unit that acquires a first image feature value for a retrieval target image; a retrieval unit that retrieves an image feature value that is similar to the first image feature value from the image feature values, based on the first image feature value; a determining unit that determines a linear conversion parameter to be used for linear conversion out of a group of linear conversion parameters based on image feature values for images of the same photographic subject obtained under conditions, based on the first image feature value and image feature values for said photographic subject; a conversion unit that converts the first image feature value by the linear conversion parameter, and converts the image feature value using said linear conversion parameter; and an output unit that outputs the conversion results.
