Claim One:
1. A surveillance image retrieval apparatus comprising: a surveillance image acquirer that acquires a series of surveillance images picked up by an imager; a feature amount generator that extracts a face image from the surveillance images and generates the feature amount of the extracted face image; an image feature amount memory that stores a face image and other metadata associated with an acquired feature amount; a face image designator that selects an appropriate face image from face images stored in the image feature amount memory or in a surveillant device in accordance with an external input, and designates the selected face image as a query image for a person search; a similar image searcher that searches the series of surveillance images stored in the image feature amount memory for a face image similar to the designated face image; a presentation image selector that examines surveillance images that are close in imaging time to the similar image retrieved as a result of the search, and selects presentation surveillance images that contain face images of the same person as a person depicted by the similar image; and a screen data generator that outputs the presentation surveillance images selected by the presentation image selector.
