ABSTRACT:
An image processing apparatus for embedding predetermined information in an image includes an input unit for inputting the image, a division unit for dividing the input image into plural image regions, a periodicity generation unit for generating plural different periodicities, an addition unit for adding a predetermined value to a pixel value of each pixel in the image region divided by the division unit, on the basis of the periodicity, and a selection unit for selecting the periodicity for the addition from among the plural periodicities, in accordance with the predetermined information. Thus, image quality deterioration is reduced and an extraction error ratio at a time of extracting additional information is also reduced in a method of embedding the additional information in the image.
