Abstract
Upon embedding additional information in image information, since an image region in which the additional information can be embedded is limited, the information size that can be embedded is often limited, and all pieces of additional information cannot be embedded. Before the additional information is embedded in the image information, distribution information of pixel values is obtained by scanning the image information, and the information size that can be embedded is detected and displayed on the basis of the obtained distribution information of pixel values.
