Example implementations relate to cross-calibration of imagers. For example, cross-calibration of imagers can include modeling a response of each of a plurality of imagers to a color sample, modeling a response of a composite the a plurality of imagers to the color sample based on the modeled response of each of the plurality of imagers to the color sample, generating generate a cross-calibration of the modeled response of each of the plurality of imagers to the modeled response of the composite of the plurality of imagers, and generating a calibration of the modeled response of the composite of the plurality of imagers to a response of a reference imager.

Cross-calibration of imagers

Example implementations relate to PRNU suppression. For example, PRNU suppression may include performing a calibration surface PRNU characterization using a scanning system, performing a document-based PRNU characterization using the scanning system, and determining a correction function for PRNU suppression for the scanning system based on the calibration surface PRNU characterization and the document-based PRNU characterization.

Photo response non-uniformity suppression

A printing system and method for printing selected images on a web page. The web page is automatically analyzed to identify image files associated with the web page, and the image files are automatically filtering according to predetermined criteria so as to identify qualified image files. At least one of the qualified image files is selected for printing, and then printed. A proof sheet having an image identifier and a corresponding selection area or image specifier for each image file may be printed. Selection areas of the proof sheet can be marked to indicate the image files to be printed and then optically scanned to detect the images selected for printing, or the image specifiers can be entered into the printing system to specify the images selected for printing.

Printing web page images via a marked proof sheet

A multifunction printing system, and a method for processing image files, which allows a sequence of multiple image processing operations on digital image files, such as photographs taken by a digital camera, to be specified and initiated at a single point in time. The system includes a command interface through which default values for image processing parameters can be set and an initial image processing operation initiated. The system also includes a scanner for receiving a combination proof sheet and order form. Prior to scanning, the proof sheet is marked by the user to identify the image files to be processed, any overriding image processing parameter values for some or all of the images, and any additional image processing operations to be performed. Image processing operations include printing image files, storing image files on a mass storage device, and sending image files via fax or e-mail.

Specifying image file processing operations via device controls and a user-completed proof sheet

Methods for storing and retrieving digital image files, such as photographs taken by a digital camera, to and from an archival image storage system such as a file server or a mass storage medium. A combination proof sheet and order form is printed containing an array of thumbnail images, corresponding image selection user designation areas, and a storage selection user designation area markable by the user to specify selected images to be stored on or retrieved from the image storage system. The form is scanned to detect the user designation areas completed by the user, and then perform the indicated operation. A printing system includes programming for generating, scanning, and processing the form, and for storing and retrieving the selected images.
