Image search apparatus
View Patent ↗An image search apparatus includes a hard disk. A plurality of images photographed by a surveillance camera are recorded on the hard disk with luminance information. When an arbitrary image is selected as a reference image from among the plurality of images recorded on the hard disk, and an arbitrary area of the reference image is designated as a search area, a CPU calculates a difference value of the luminance information of the search area between the reference image and each of other images. Furthermore, the CPU specifies an image in which the calculated difference value exceeds a threshold value from among the other images, and the specified image is displayed on the display.
1. An image search apparatus, comprising:
a fetcher for repeatedly fetching an object scene image photographed by a camera;
a dividing/detecting processor for dividing each of the object scene images fetched by said fetcher into a plurality of areas so as to detect a plurality of luminance-related components respectively corresponding to said plurality of areas;
an assigner for assigning to a noticed object scene image the plurality of luminance-related components detected from the noticed object scene image by said dividing/detecting processor;
a recorder for recording the object scene images to each of which the plurality of luminance-related components are assigned by said assigner;
a first acceptor for accepting a designating operation for arbitrarily designating at least one of said plurality of areas as a search area; and
a searcher for searching a specific object scene image in which a specific luminance-related component(s) corresponding to the search area designated by the designating operation satisfies a predetermined condition, from among the object scene images recorded by said recorder.
2. An image search apparatus according to claim 1 , wherein the predetermined condition is a condition that a difference with the specific luminance-related component(s) of a reference object scene image exceeds a threshold value.
3. An image search apparatus according to claim 2 , further comprising a second acceptor for accepting a setting operation for setting the threshold value.
4. An image search apparatus according to claim 2 , further comprising a third acceptor for accepting a selecting operation for selecting the reference object scene image from among the object scene images fetched by said fetcher.
5. A surveillance system provided with an image search apparatus according to any one of claims 1 to 4 .
