Description

Image retrieval system according to the invention acquires the image information of the captured image, the image effect is eliminated in the captured image at the same time obtained much information captured image and ambient light for a predetermined area by the imaging means and possible the sensor image of the predetermined area sensor information by the sensor, storage means for associating and storing, using said sensor data, similar to the selected target captured image from a plurality of the captured image similarity And a search processing means for searching for an image.

According to the image retrieval system according to the present invention, by using the sensor information of the sensor image of an image which the influence of ambient light is excluded from the acquired sensor capable, similar to selected target captured images from a plurality of captured images Since similar images can be searched, similar images can be searched with stable search accuracy without being affected by ambient light . Further, since the sensor information from the sensor has less information than image information from the imaging means, by searching for similar images using the sensor information, it is possible to reduce the amount of information to be processed, the computer resource Can reduce the load. In this way, it is possible to provide an image search system that can search for similar images with more stable search accuracy than conventional image search systems without being affected by disturbance light . In addition, it is possible to provide an image search system that can reduce the load on computer resources.
