Abstract

An image storage apparatus comprises: a photograph information analysis processor for outputting photograph information perception data quantitatively associated with perception terms (language) relating to photograph images; and a color perception analysis processor for outputting color perception data quantitatively associated with perception terms relating to colors of the images. The output data are stored in the storage apparatus. When receiving search terms of photograph information and color perceptions of retrieval target images, an image retrieval apparatus compares the search terms with image content language data stored in the storage apparatus to narrow the language data, and extracts images in descending order of priority (scores) of the perception terms corresponding to the search terms with reference to photograph information and color perception data attributed to the retrieval target images and including the narrowed language data. Images best meeting the perception requirements of users can be stored and retrieved accurately at high speed.
