Abstract:
1. An image scanning and processing system, comprising: a scanner for scanning an image, configured to generate a stream of data encoding a scanned image; a controller configured to control and process data received from the scanner, wherein the controller is configured to derive from a stream of data a primary stream to be stored in the master file, and a separate stream to create a preview image; and a file storage device configured to store the master file including data from the primary stream of data, wherein the controller creates the preview image with a lower data size than the scanned image from the separate stream, wherein the controller extracts data encoding the preview image from the separate stream of data on the fly, before the scanning of the image is finished, and writes the extracted data to a thumbnail file, thereby creating the preview image, wherein the controller scales down the scanned image when the stream of data encoding the scanned image arrives at the controller, thereby extracting the data encoding the preview image from the separate stream of data.
