PROBLEM TO BE SOLVED: To simultaneously realize improvement of a detection rate of an augmented reality marker and improvement of detection processing speed thereof.SOLUTION: An LED 12 is disposed as a light emitter at the position of each corner of an AR marker 11 (four-point positions). When the AR marker 11 surrounded by a plurality of LEDs 12 is photographed, the photographed image is binarized in accordance with luminance of an LED 12, the plurality of LEDs 12 are detected from within the binarized image, an area surrounded by the plurality of LEDs 12 are then further binarized, and the AR marker 11 is detected on the basis of the binarized image. |
