摘要:
An image processing apparatus embeds information into image data without an overhead. The image processing apparatus includes a selection unit (41) for selecting some of the pixels forming the image data. A changing unit (42) embeds the information into the pixels selected by the selection unit (41) by swapping the bits of the values of the selected pixels according to the information.
