ABSTRACT:
An image-retrieving system for retrieving a desired image from a data base. A storage device in the data base stores a plurality of images, additional information for identifying each of the plurality of images and calculated feature data for identifying each of the images. A first input device inputs additional-information data for identifying a desired image stored in the data base. An additional-information selection device selects a first set of candidates as the desired image by comparing the input additional-information with the stored additional-information for each of the stored plurality of images. A second input device inputs an illustrative image, which is illustrative of the desired image, and a generation device generates feature data from the input illustrative image. A selection device selects as the desired image a one of the candidates whose stored feature data is most similar to the generated feature data of the input illustrative image.
