摘要

PROBLEM TO BE SOLVED: To retrieve an item relating to a retrieval object with accuracy.SOLUTION: A retrieval device 10 includes: a first reception unit 22A; an acquisition unit 26; a calculation unit 30; a determination unit 32; and a first display control unit 34. The first reception unit 22A receives selection of at least one of a plurality of predetermined mask images showing an area of a retrieval object. The acquisition unit 26 acquires a first image. The calculation unit 30 calculates a first feature amount of an extraction area designated by a selected mask image in the first image. The determination unit 32 retrieves second information in which a second image and a second feature amount of a plurality of items are associated and determines the second image corresponding to the second feature amount in which similarity to the first feature amount is equal to or greater than a threshold value. The first display control unit 34 performs control to display the determined second image on the display unit 18.
