Abstract: A method and system for de-screening an image signal utilizing a bank of filters to provide several increasingly blurred versions of the original image signal is disclosed. At any given time, only two of these blurred versions are created, on a pixel-by-pixel basis. The outputs from the selected pair of blurred signals are then blended together to create a variable blending output that can vary smoothly from no blurring to maximum blurring in a smooth and continuous manner. In addition, the method provides the capability to enhance text and line art by using a variable un-sharp masking mechanism with independent post-blur sharpening control, and the capability to detect and enhance neutral (no-color) output pixels.

Abstract: In case the digital broadcasting wave contains printable contents data, the invention multiplexes a message, a mark or an icon on the display screen of the currently viewed program or outputs an audio message to inform the user of the presence of such contents data. The invention prevents a situation where the contents data cannot be or are not printed even though the data are transmitted, and allows the user to correctly prepare the type or number of sheets in advance in the printer.

Abstract: Methods and apparatus, including computer program products, for previewing images to be rendered on multiple pages. A representation of the image mapped onto a two dimensional canvas is displayed. The canvas representation includes content of the image and describes a layout of the image content across multiple pages.

Abstract: Provided is a printing system capable of printing, when one or more pages are replaced after raster image processing (RIP), by performing RIP of only the page(s) to be replaced. A job ticket is issued from a printing apparatus. In a printing data creating apparatus, information of page data for replacement is added to the content of the job ticket and then sent to the printing apparatus together with the page data for replacement. In the printing apparatus, only the received page data for replacement is subjected to RIP, and then printing after replacement processing is executed in accordance with the job ticket. It is unnecessary to perform again RIP of printing data irrelevant to the replacement. This increases the efficiency of processing and also lowers the cost.

Abstract: A method, system, and computer program product for transmitting print-ready electronic documents to a printer using e-mail as a transport mechanism. Responsive to a user request, a source PC transmits a document in print-ready format, so that there is no need for the printer to run or activate the software application that was used to generate the document. Furthermore, by rendering the document at the source PC, the invention ensures that the user's selected print settings and preferences are preserved. The user need not be concerned with whether the destination printer has the appropriate software or is configured appropriately for the user's document. In alternative embodiments, the user grants permission to print a local document. Subsequently, when a recipient wishes to print the document, the most current version is retrieved from the source PC, so that the printed document reflects any changes that may have been made after the permission was granted.

Abstract: JPEG data is efficiently recompressed and transmitted to a remote color facsimile device. Before transmission of recompressed JPEG data, an anticipated transmission time is displayed for enabling the user to easily select the desired compression ratio. To generate recompressed JPEG, a Huffman decoder is provided for decoding encoded data and temporarily generates decoded data. Table generator multiplies the predefined quantization table values by the prescribed value to generate the modified quantization table. Intermediate data generator generates the intermediate data by dividing the encoded data by ratio n, which is derived by dividing predefined quantization table by the modified quantization table. Huffman encoder encodes the intermediate data to create new encoded data. Recompressed JPEG data includes the newly coded data and the modified quantization table.

Abstract: In a method for generating an IPDS data stream, different levels are defined with level numbers, whereby in each level a group of print data is combined on which the same operation is implemented. The operations are defined by operation numbers. A linkage exists between the level numbers and the operation numbers such that an operation number can be unambiguously assigned to a level number so that it can be determined using the linkage which level is provided for which operation. It is not necessary to generate and to maintain complex tables in order to be able to administrate the level corresponding to the required specification.

Abstract: In a printing apparatus having full-color and monochrome print processes and a method therefor, whether a page to be printed is color or monochrome is checked. The presence of an immediately preceding page which is successively printed before a page to be printed that is determined to be monochrome, and the attribute of the immediately preceding page are determined. The presence of a succeeding page which is successively printed after the page to be printed, and the attribute of the succeeding page are determined. The number of pages corresponding to the determination results is set. The print process of the page to be printed is decided on the basis of the presence of succeeding pages corresponding to the number of pages and their attributes.

Abstract: As a method of calibrating colors other than primary colors such as secondary colors, the contents of an ink color-separation table are reconstructed. However, it is difficult to reconstruct the ink color-separation table within the limitation of total ink amount permissible for a print sheet. Accordingly, a color patch corresponding to a signal value of a color to be calibrated is formed in a printer, then the signal value is calibrated based on a measured color value of the formed color patch and a target value corresponding to the signal value of the color to be calibrated, and calibration multidimensional table data is generated based on the measured color value of the formed color patch.
