Image Number 3 for United States Patent #8116580.
A system, method, and process for embedding low frequency image details and high frequency image details into a final digital image file. A digital image file is stored with embedded low and high frequency image details that are accessible with a compatible digital image decoder and a non-compatible digital image decoder. Non-compatible digital image decoders access only a compressed low frequency image of the original digital image contained in the final digital image file. Compatible digital image decoders use the embedded high frequency image details contained in the final digital image file to render a high resolution image.
