Abstract
The present invention generally relates to a digital scanner for scanning images and is directed to a method and apparatus for accurately scanning documents and for processing digital data to generate digital images as accurately as possible. The scanning system described in this application provides recommended settings for image mode and image parameters to assist the user in adjusting the settings to match the original document. The image data is analyzed to determine the optimum settings.
Claims12
An image improvement system for determining the optimum settings for image reproduction by a scanner which is designed to read, based on current settings, an image from an original document and generate a digital image data file representing said document, said system comprising:
- an image data processor which generates data from which a full page video histogram and a pixel tag histogram may be generated based on said digital image data file;
- an image analyzer processor which generates said full page video histogram and said pixel tag histogram and collects statistics based on said full page video histogram and said pixel tag histogram, analyzes said statistics, and generates recommended settings for image mode and image parameter settings, based on said statistics, for improving said image reproduction of said scanner;
- a scanning assist processor for comparing said recommended settings with current settings and generating recommended adjustments;
- and
- a user interface for receiving said recommended adjustments and presenting said adjustments to a user.
A scanning system for reproducing an image from an original document comprising:
- a scanner for receiving an original document and generating an image data file representing said document;
- an image data processor which converts said image data file to a digital image data file having full page video characteristics and pixel characteristics contained therein;
- an image analyzer processor for generating a full page video histogram and a pixel tag histogram, collecting statistics based on said full page video histogram and said pixel tag histogram, analyzing said statistics, and generating recommended settings for image mode and image parameter settings, based on said statistics, for improving said image reproduction of said scanner;
- a scanning assist processor for comparing said recommended settings with current settings and generating recommended adjustments;
- and
- a user interface for receiving said recommended adjustments and presenting said adjustments to a user.
In a scanning system for reproducing an image from an original document, a method for determining the optimum settings for image reproduction by said scanning system comprising the steps of:
- reading, based on a group of current settings, an image from an original document and generating an image data file representing said document;
- converting said image data file to a digital image data file having full page video characteristics and pixel characteristics contained therein;
- generating a full page video histogram and a pixel tag histogram;
- collecting statistics based on said full page video histogram and said pixel tag histogram;
- analyzing said statistics, and generating recommended settings for image mode and image parameter settings, based on said statistics, for improving said image reproduction of said scanner;
- comparing said recommended settings with current settings and generating recommended adjustments;
- and
- presenting said adjustments to a user.
