According to an aspect of an embodiment, a method of embedding information into an image comprises dividing the image into a plurality of blocks, providing a plurality of embedded blocks corresponding to the plurality of blocks, respectively, each of the embedded blocks having the same size as each of the blocks when each of the blocks is smaller than a predetermined size, each of the embedded blocks having the predetermined size and being placed at the center of each the block when each of the blocks is not smaller than the predetermined size and selectively modifying the characteristic value of each of the embedded blocks in accordance with the information to be embedded.

Information embedding method, information obtaining method and apparatus

An apparatus detects an area specified based on a mark of a specific color out of three primary colors in pigment or three primary colors in light from an image. An other-color-information eliminating unit eliminates information of other colors from a tone level of the specific color by correcting the tone level of the specific color based on tone levels of two colors other than the specific color out of the three primary colors in pigment or the three primary colors in light. An area detecting unit detects the area by specifying the mark based on the tone level from which the information of other colors is eliminated.

Method and apparatus for detecting image area, and computer product

According to an aspect of an embodiment, a method of embedding information into an image has obtaining an image data by taking the image by an image input device, dividing the image data into a plurality of blocks, determining an area in each of the blocks on the basis of a resolution power of the image input device, where a characteristic value may be modified in accordance with the information, respectively, comparing the size of the block with the size of the area and modifying a characteristic value of each of the blocks in accordance with the information to be embedded when the ratio of the size of the area with respect to the size of the blocks is smaller than a predetermined value.

Method of embedding informaton into image

A dividing unit divides image data into a plurality of blocks. An extracting unit extracts a feature index of a first color component and a feature index of a second color component in each of the blocks. A registration unit registers information about a correspondence between the feature index of a second color component and a change in the feature index for the first color component. A code embedding unit embeds a predetermined code into the image data, by changing the feature index of the first color component based on the feature index of the second color component, using the information registered.
