SURVEILLANCE IMAGE RETRIEVAL APPARATUS AND SURVEILLANCE SYSTEM
First Claim
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.

Abstract
Disclosed is a surveillance image retrieval apparatus capable of generating an image representing a search result that a surveillant can visually confirm, even if a face image used is not suitable for the visual identification of a person. The surveillance image retrieval apparatus includes a surveillance image acquirer, which acquires surveillance images; a feature amount generator, which extracts a face image from the surveillance images and generates the feature amount of the extracted face image; an image feature amount memory for storing a face image, a surveillance image, and other metadata associated with an acquired feature amount; a face image designator, which selects an appropriate face image in accordance with a user'"'"'s input, and designates the selected face image as a query image for a person search; a similar image searcher for searching 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, which examines surveillance images that are close to the search result in imaging time, and selects presentation surveillance images that include face images of the same person; and a screen data generator for outputting the presentation surveillance images selected.
