| Number | Title | Issue Date |
| 7847844 | Information processing apparatus and method for determining whether a detected index is an index included in sensed image data A sensed image of the physical space is acquired by an image sensing apparatus. One or more indices are detected from the sensed image. The reliability of each of the detected results is determined by calculating a first reliability value based on the sensed image a... | 12/07/2010 |
| 7812871 | Index identification method and apparatus The orientation of each index is estimated from a sensed image, and the index detected from the image is identified based on the orientation of an image sensing device and that of the index estimated from known coordinate information of the index. In this way, indic... | 10/12/2010 |
| 7064782 | Cameras A camera comprises a sensor such as a CCD or ICCD for receiving radiation representative of a scene, a filter such as an arrangement of parallel neutral density stripes, arranged to attenuate the radiation reaching the sensor, and decoding electronics such as comb f... | 06/20/2006 |
