Abstract
A method for choosing a compression process for a scanned image includes scanning an image, forming a bitmap of the scanned image and selecting at least one portion of the scanned image as a compression test subject. The selected portion is selected by a variety of compression techniques and a score for each technique is assigned. The compression technique with the best score is then used to compress the entire bitmap of the scanned image.
Claims8
A method for choosing a compression process for a scanned image comprising:
- acquiring an image as an acquired image bitmap;
- selecting at least one portion of the acquired image bitmap as a compression test subject;
- compressing the selected portion by a variety of compression techniques, wherein said variety of compression techniques includes compression techniques added by a user to a compression library;
- assigning a score to compressed data from each technique, wherein assigning a score includes a comparison of user desires versus compression results;
- determining which compression technique has the best score;
- and
- compressing the acquired image bitmap by the compression technique having the best score.

A method for selecting a compression process for a scanned image, comprising:
- acquiring an image of a multi-page document;
- selecting at least one portion of the acquired image as a compression test subject, wherein a user input selects a number of pages of a document for compression analysis;
- compressing the selected portion by a variety of compression techniques including compression techniques added by a user to a compression library;
- assigning a score to compressed data from each technique, wherein assigning a score includes a comparison of user desires versus compression results;
- determining which compression technique has the best score;
- compressing the entire bitmap of the number of pages by the compression technique having the best score;
- and
- compressing pages of the document not selected by the user input with a predefined compression technique.
