The security encoding unit includes at least a first detector for detecting first security information of a first image based on a first original image data, a second detector for detecting second security information of a second image based on a second original image data, a first security encoding device for performing security encoding processing on the first original image data to generate the first image data, and a second security encoding device for performing security encoding processing on the first original image data to generate the second image data.
