1. An image processing device, comprising: a sectioning device configured to section an image into a plurality of sections to be processed; a classification device configured to classify the plurality of sections to be processed into at least a clarification-processing-adapted area for embedding a latent image into the image, and an obfuscation-processing-adapted area for embedding a digital watermark into the image based on a characteristic of the image; a latent image embedding device configured to embed the latent image into the clarification-processing-adapted area; a digital watermark embedding device configured to embed the digital watermark into the obfuscation-processing-adapted area; and a clarification processing device configured to determine whether a pixel position is within a remaining area, and on a condition that it is determined that the pixel position is within the remaining area, the clarification processing device is further configured to assign a value to a pixel corresponding to the pixel position, wherein the assigned value corresponds to a pixel value for clarification processing and a pixel value for input image data.
