摘要： To provide a device capable of determining uniquely the direction of rotation applied to an image and extracting digital watermark information correctly even in the case where a registration signal having a symmetric axis is embedded. A device for enabling digital watermark information to be extracted from image data having the digital watermark information embedded therein in such a manner that it can hardly be perceived by human eyes, in which processing for extracting rotation information and position information from the image data is performed plural times for rotation angles different from one another. For extracted position and rotation information, confidence coefficients indicating accuracy thereof are calculated. The position and rotation angle at which the digital watermark information is embedded are determined based on the confidence coefficients.

摘要： An image processing method is provided. This method comprises: a first information extraction step of extracting first information, including a registration signal used to correct the geometrical distortion of an image; a determination step of employing results obtained at the first information extraction step to determine whether second information is to be extracted from the image; a division step of dividing the image into at least one block; and a selection step of selecting the block. In this method, the first information and the second information are embedded in the image as invisible or less visible electronic watermarks, and are added to components of said image that are less easily discerned by a human's eyes. Further, the amount of said first information is smaller than the amount of said second information, and the first information is embedded more deeply in the image than is the second information.

摘要： To provide a variety of methods for extracting digital watermark information from an image as correctly as possible. For example, a first pattern arrangement and a second pattern arrangement which is different from the first pattern arrangement for use in a calculation for extracting the digital watermark information are provided. A state of an original image without the digital watermark information embedded is inferred, using a second pattern arrangement, and a reliability of the digital watermark information to be extracted in accordance with the state is determined. Or to decide the embedding position of the digital watermark information from the image data, the extracting start position is discriminated by detecting the positional information by multiple times at the different extracting start positions. Or to detect a geometrical distortion, a registration signal is embedded on the image.
