Abstract
Specific information such as the type of performed image processing, and date is disassembled to bits, and the resulting bits are placed, e.g., in the least significant bit positions of pixels within processed image data. By this arrangement, when image processing is performed on original image data, it can be determined from processed image data what processing was executed on the image data.
