  • Patent number: 10044948
    Abstract: A pixel cell includes a photodiode to accumulate image charge. A global shutter transistor is coupled to the photodiode to reset the image charge in the photodiode in response to a global shutter control signal. A global shutter control signal generator circuit generates the global shutter control signal to have a first value signal or a second value signal. The first value signal is coupled to turn on the global shutter transistor to reset the photodiode. The second value signal controls the global shutter transistor to be in a low leakage off mode. A supply circuit is coupled to provide the second value signal to the global shutter control signal generator circuit. The supply circuit includes a variable filter circuit coupled to an output of the supply circuit to selectively vary a bandwidth of the second value signal in response to a bandwidth select signal.

  • Patent number: 7433084
    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.

  • Patent number: 7382486
    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.

  • Patent number: 7375856
    Abstract: An efficient method and system for eliminating halftone screens from scanned documents while preserving the quality and sharpness of text and line-art is disclosed. The method and system utilizes one or more independent channels with different sensitivities (e.g., Max, High, and Low) to provide high quality frequency and magnitude estimation. The most sensitive channel (Max) derives the frequency estimate, and the remaining channels (e.g., High and Low) are combined to create the screen magnitude. The Max channel is the most sensitive and will usually report the existence of frequencies even when the screen is very weak. Therefore, the screen frequency must be additionally qualified by the screen magnitude. The screen magnitude can be interpreted as the level of confidence that the local neighborhood represents half-toned data.

  • Patent number: 7375852
    Abstract: An application program may support multiple color spaces, such as Cyan Magenta Yellow blacK (CMYK) and Red Green Blue (RGB). Many computer operating systems have graphics drawing engines that only support RGB color space. For supporting non-RGB color spaces, the application program can use a color mapping table that defines a relationship between two color spaces such as CMYK and RGB. By generating unique RGB identifiers that can be passed through a graphics drawing engine and by using escape functions of a page description language, an application program can modify a printer file written in a page description language such that a non-RGB color space such as CMYK can be supported for publishing an electronic document.

  • Patent number: 7375835
    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.

  • Patent number: 7375858
    Abstract: Ablation data of a region other than an image region, which ablation data is required for a positive-type printing plate, is added at a printing plate automatic exposure device side. Thus, a disadvantage of a time duration for transmission of job data from a PC being slowed because of the ablation data is solved. As a result, image recording operations can be made more efficient. Furthermore, the ablation data includes non-exposure portions at regions corresponding to peripheral edge portions of the printing plate. Consequently, light does not impinge on a leading end chuck, a trailing end chuck and the like, and the ablation data can be made suitable for interlaced scanning.

  • Patent number: RE40775
    Abstract: A difference in feed roller diameter from one printer to another causes a media to advance by a different amount for a given rotation of a drive shaft to which the feed roller is coupled. Such variation in advance distance is a linefeed error. Mean linefeed error is determined and corrected by printing a test plot having several areas. Each area is formed of the same image pattern, but is printed at a different linefeed error adjustment to compensate for mean linefeed error. The different adjustments are prescribed and span a typical compensation range for a given print engine model. The different adjustment factors cause banding to occur in some areas. The user picks one of the test pattern areas which has the highest print quality (i.e., least or no banding). The linefeed adjustment factor corresponding to such area is used for normal printing.
