Developing processing performed after embedding digital watermark information in CCD-RAW image data greatly damages the embedded digital watermark information. Prevention of copying, tampering, and illicit use of an image photographed in the CCD-RAW mode cannot be guaranteed by the digital watermark at the photographing time point. In order to reliably prevent copying, tampering, and illicit use of an image, digital watermark information is attached to unprocessed image sensing data acquired by an image sensing device. After the image sensing data undergoes image processing, the attached digital watermark information is embedded in the resultant image sensing data.
