Abstract: An inkjet printer that is configured to perform multi-pass printing operations includes at least one printhead, a memory and a controller. The controller receives a input row of image data for one pass including a plurality of pixels. The controller uses a table of index lookup offsets in the memory to generate a row of output image data with at least one pixel at a first index in the input row being located at a second index in the output row. The controller operates the inkjets in the printhead to eject at least one drop of ink using an inkjet in the printhead that corresponds to the second index in the output row and that is different than another inkjet in the printhead that corresponds to the first index in the input row.

Abstract: A scanner enables full productivity and individual image size detection, without user intervention for mixed size originals in both simplex and duplex scanning modes. The scanner provides high-productivity single pass scanning while preserving the image size for each of the document scanned. In addition, the scanner may support duplex scanning by adding a second image sensor, for example, in the document handler. Methods of scanning are also provided.

Abstract: A manual windowing with auto-segmentation assistance method and system are disclosed that include defining manual tags to be assigned to one or more windows via a tag selection module, assigning the defined manual tags to the one or more windows via a manual tag assignment module and auto-segmenting the one or more windows within the display medium by producing auto-segmentation tags via the auto-segmentation module. Furthermore the method and system according to this invention provide for mapping tags to the auto-segmentation tags via a tag mapping module and merging the manual tags and the auto-segmentation tags via a merging module.

Abstract: The present invention generally relates to a digital scanner for scanning images. More specifically, the present invention is directed to a method and apparatus for accurately scanning documents and for processing digital data to provide digital images stored in memory, which can be retrieved for printing on support material or for displaying on a display screen.

Abstract: A system and method for processing segmentation tags is disclosed. The system comprises a neighborhood analysis module, transition analysis module, and a tag cleaning module. The neighborhood analysis module generates a neighborhood block tag prediction from a block of segmentation tags having a first predefined relationship with a current tag. The transition analysis module generate a transition block tag prediction from a block of segmentation tags having a second predefined relationship with the current tag. The tag cleaning module modifies selected segmentation tags based on the neighborhood block tag prediction and the transition block tag prediction. The method comprises identifying a current segmentation tag to be cleaned; generating a tag prediction from a plurality of segmentation tags having a predefined relationship to the current segmentation tag; and generating a cleaned segmentation tag for the current segmentation tag based upon the current segmentation tag and the tag prediction.
