<p>An image detection device and an image detection method for efficiently detecting a specific image area existing in an image. The image detection device first changes the size of an original image on the basis of the initial value of a magnification (scaling factor) with respect to the original image and detects the specific image (license plate, for example). The change of the size of the original image and the detection of the specific image are repeatedly carried out with the magnification changed each time.By repeating the detection with an image scaled up or down, speeding up is achieved, and also by determining an area where no other specific image exists and performing the detection efficiently by using this information, speeding up is achieved.</p> |
