Abstract:
1. A camera operating system comprising: a camera; a camera operating means for operating the camera to capture an imperceptible two-dimensional geometrical code in an image displayed on a display device; detecting means for detecting difference between each of a plurality of the two-dimensional geometrical code captured by the camera; a decoding means for decoding the two-dimensional geometrical code; a storage means for storing decoded two-dimensional geometrical code data; a camera operation start means for starting repetitious capture operation; and a camera operation adjustment means for adjusting capture operation timing in synchronization with appearances of the two-dimensional geometrical code on the display device, wherein the decoding means repeatedly decodes the two-dimensional geometrical code that are repeatedly captured by the camera, and the storage means stores the decoded two-dimensional geometrical code data between a start code and an end code as a body of data.
