"High-compression PDF conversion technology" employs document analysis technology to extract text and image data and separate them into multiple layers. This technology enables each layer to then be optimally compressed, providing for a high-compression ratio while maintaining high resolution.
Using conventional compression methods, an A4-size color image scanned at 150 dpi can be compressed to a file size of about 2 MB. With this technology, the same image scanned at a resolution equivalent to 300 dpi can be reduced to roughly one tenth of that size (200KB). Canon is the first company in the world to incorporate this technology into MFDs, and has dramatically improved the capability of handling color document image data, which entails particularly high volumes of data.
