To improve image retrieval accuracy by eliminating the limitations of feature values to be used for determining similar images in image retrieval.

This image retrieval apparatus extracting a similar image similar to an input image and includes: an input image information acquiring section 101, an image processing section 102 for generating a plurality of extraction condition information on the basis of the acquired input image information, an image information extracting section 103 for extracting a similar image on the basis of each of the plurality of generated extraction condition information, and an extraction result processing section 104 for generating display information for displaying the extracted similar image. The extraction result processing section 104 generates the display information so as to display the extracted similar image in association with extraction condition information for extracting the similar image.
