<p><P>PROBLEM TO BE SOLVED: To provide an image data processor capable of improving processing speed while reducing a size of a storage section for storing image data. <P>SOLUTION: The image data processor includes: an encrypting section for receiving image data, comparing (2n-1)-th pixel data and 2n-th pixel data with each other, and generating a header value, an encoded value, and a reference value for encrypting them; a storage section connected to the encryption section, for storing the header value, the encoded value, and the reference value generated by the encrypting section; a decrypting section connected to the storage section, for restoring to (2n-1)-th pixel data and 2n-th pixel data respectively using the header value, the encoded value, and the reference value; and a D/A converting section connected to the decrypting section, for converting the restored data into analog signals and outputting. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
