Abstract
An image scanner apparatus scans a document and provides image data in digital form representing the scanned document. The compression apparatus detects characteristics of the image data and compresses the image data using parallel compressors, each employing a different encoding scheme. The apparatus then selects compressed image data encoded by one of the compressors in accordance with the detected characteristics and stores the selected data.
