Abstract: PROBLEM TO BE SOLVED: To surely detect an electronic watermark image without giving an influence to an original image in an image by making the intensity of the electronic watermark image constant regardless of the image quality. SOLUTION: An electronic watermarks inserting part 2 inserts a watermark image into the original image. An electronic watermark intensity detecting part 6 detects the intensity of the electronic watermark image inserted into the original image, and sets the electronic watermark intensity in accordance with the intensity of the electronic watermark image. For this reason, the irregularities of the electronic watermark intensity are eliminated and the electronic watermark intensity can be optimally set. It is accordingly possible to prevent electronic watermark influence from appearing on a screen and the electronic watermark from not being detected.

Abstract: PROBLEM TO BE SOLVED: To accurately detect an electronic watermark from a DCT (Discrete Cosine Transform) area, even when the area setting of an electronic watermark pattern does not match DCT block configuration.
SOLUTION: The electronic watermark detector 10 is provided with a correlation detection section 12, that detects an electronic watermark component detection value WM which is the correlation value between an electronic watermark pattern W to be detected and detection object image data Y by each one a plurality of areas set to the detection object image data Y. The electronic watermark detector 10 uses the correlation detection section 12 for obtaining a correlation value to be extracted from one area not only from the data of that area, but also by performing correlation arithmetic operations between the overall detection object image data Y and an electronic watermark pattern for calculating the correlation value of each area of the same size as that of the detection object image data Y.

Abstract: PROBLEM TO BE SOLVED: To provide a digital watermark embedding processing device and its method, that can stably detect a digital watermark. SOLUTION: The digital watermark embedding processing device is configured to respectively detect a digital watermark, corresponding to each bit from an image to which the digital watermark has been embedded, for setting the strength of the digital watermark pattern of each bit, on the basis of excess/deficiency of the strength of detecting the digital watermark corresponding to each bit thereby executing re-embedding or additional embedding. Furthermore, the processing device sets an object detection strength, embeds additional bits with low strength on the basis of the setting object value and conducts embedding with reverse correlation as to bits with excess strength. Furthermore, the added or adjusted embedding strength is set on the basis of small area data of an original image. As a result of this configuration, the digital watermark can stably be detected from the embedded image, and the deterioration in the image quality by the digital watermark pattern can be suppressed.
