An object of the present invention is to provide an image search device and an image search method by which search efficiency is improved. The image search device includes a personal characteristic database (21) where images of individual multiple photographic subjects obtained by shooting by multiple cameras (10) are stored in the form of a database, a similarity search unit (22) that performs a similarity search by using a query image from the images of the individual multiple photographic subjects stored in the personal characteristic database (21), a query image generation unit (23) that generates a new query image by synthesizing, of the multiple images obtained by the similarity search unit (22), a correct image used as a criteria with another correct image or synthesizing the correct image used as the criteria with a negative-positive inverted incorrect image, and an image processing unit (24) that performs image processing for displaying the images retrieved by the similarity search unit (22) on a search terminal (30). |
