Abstract
JPEG data to be printed is Huffman-decoded on a block-by-block basis and is stored in a Huffman decoded data storage unit as Huffman decoded data, image data is generated by performing a later-stage decoding process (group decoding, run-length decoding, inverse quantization, inverse DCT) on the Huffman decoded data, a display process for displaying an image in a display unit based on the generated image data is executed, and the JPEG data is reconstructed by inserting RST markers at intervals equivalent to every stripe width while encoding the Huffman decoded data produced during the display process and stored in a reconstructed JPEG data storage unit. Then, when rotated printing is instructed, rotation/decoding that performs rotation while decoding the stored reconstructed JPEG data using the RST markers is carried out, print data is created from the image data obtained by the rotation/decoding, and a printing process is executed.
