Provided is an image search system with which, while preserving search precision, it is possible to alleviate transmission volume. A search server (300) acquires from a recorder (200) only low-dimension data which normally has a low data volume. When the density of low-dimension image data within a feature space is greater than or equal to a prescribed threshold value, that is to say, when the number of dimensions for carrying out an inter-image identification with only the low-dimension data is insufficient, the search server (300) acquires from the recorder (200) high-dimension image data for the low-dimension data. Thus, while preserving search precision, it is possible to alleviate data transmission volume of a communication path (130). |
