Title: Method and device for embedding electronic watermark, method and device for detecting electronic watermark and software storage medium
Inventor: HIRAI JUN
IPC: H04N7/081
Filed: 2000-04-21
Abstract: PROBLEM TO BE SOLVED: To embed an electronic watermark in an unperceivable range and to also detect the electronic watermark without mistake by adaptively controlling embedded data quantity. SOLUTION: An electronic watermark embedding device side avoids image quality disturbance with respect to information that can be grasped by a detector side, e.g. by adaptively adjusting embedment quantity. For instance, the embedment quantity is increased in the vicinity of 100 IRE where noise is inconspicuous on the screen of a television receiver. On the contrary, the embedment quantity is decreased in the vicinity to 30 IRE where noise becomes conspicuous. The electronic watermark detector side grasps the state of a vide signal and suppresses the occurrence of erroneous detection by dynamically adjusting a detection threshold in accordance with the state.
