Abstract
An image signal output device includes a code generating means for generating a two-dimensional geometrical code based on a source data, a obtaining means for retrieving a sequential image signal, a code inserting means for inserting the two-dimensional geometrical code in the sequential image signal and a output means for outputting the sequential image signal. The code inserting means imperceptibly inserts the two-dimensional geometrical code in the sequential image signal, and the output means outputs the sequential image signal having the two-dimensional geometrical code inserted therein. The imperceptible two-dimensional geometrical code is captured by a camera in a cell phone to be decoded and stored in a memory medium.

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.
