  • Patent number: 7982897
    Abstract: A printer (100) for printing based on a print job signal sent from a data processing device (200) registers print job signal sending sources and a message corresponding to each sending source in memory (111, 112). A controller (113) detects whether the sending source of a received print job signal is registered in memory. If the sending source is registered, a messaging unit (110, 111) outputs a corresponding message. Sending sources that are permitted to print can also be registered in memory (111, 112). In this case, the controller (113) detects whether the sending source of a received print job signal is registered in memory, and instructs the printer (110) to print only when the sending source is registered as permitted to print.

  • Patent number: 7979855
    Abstract: An image processing apparatus, a management system and a computer program product are disclosed that enable firmware that controls operations of the image processing apparatus to be updated appropriately, even when, for example, an initial setting in the image processing apparatus has been changed. Firmware in the image processing apparatus is stored in a rewritable storage device such as a flash ROM, and is updated by transmitting a new firmware to the image processing apparatus and rewriting the contents of the storage device. The new firmware is transmitted together with a control program (including script) that describes processing to be executed in the image processing apparatus before and/or after updating the firmware.

  • Publication number: 20110019235
    Abstract: The image forming apparatus receives image data based on multiple document images of various sizes and/or orientations. The apparatus identifies areas that are not yet assigned with document images on a single sheet of paper and identifies whether any document image can be laid out in an identified area. In another aspect of the apparatus, a maximum document image size is detected from multiple document images, and a scale factor is calculated to cause the detected maximum size match with the size of the entire area of the paper or an area obtained by dividing the paper into equal parts. In another aspect of the apparatus, a scaling factor is calculated for each document image to cause the size of the particular document match with the size of an area obtained by dividing the paper into equal parts.

  • Patent number: 7869652
    Abstract: In flicker correction of a moving picture consisting of a plurality of frames, moving averages of accumulative histograms are calculated for each frame on image data. Then, gamma tables for correcting the image data of a frame in the plurality of frames are made such that the accumulative histograms after corrected with the gamma tables match with the moving averages of the accumulative histograms. Then, the image data of the frame in the plurality of frames is corrected with the gamma tables. In some cased, each frame is divided into areas, and the flicker correction is performed for each area if necessary.

  • Publication number: 20100322511
    Abstract: In order to carry out an image processing with high precision by using a simple structure, an image processing apparatus is provided with an input unit, a storage unit, a binarization unit, and a determination unit. The input unit inputs image data of an image. The storage unit stores a first condition on absolute positions of pixels in the image and a second condition on positions of pixels relative to a target pixel. The binarization unit binarizes the target pixel based upon a color data of the target pixel and that of at least one related pixel to the target pixel to generate a binarized value. The at least one related pixel in the image satisfies the first and second conditions. The determination unit determines whether or not the image has a specified pattern, based upon the binarized values.

  • Patent number: 7843608
    Abstract: There is provided an image processing apparatus employing an error diffusion method capable of preventing a pseudo contour attributable to a delayed dot. The image processing apparatus receives an error diffused from a neighboring pixel and corrects a value (an input value of 0 to 1) of a pixel to be processed before it reduces a tone. Then a subtracter calculates an error associated with the tone reduction, which is diffused to a neighboring pixel. Herein, only for an input value of no less than 0.5 an inversion portion multiplies by ?1 an error from a neighboring pixel and an error to a neighboring pixel. Thus a dot can be free of delay to prevent a pseudo contour.

  • Patent number: 7830542
    Abstract: The printing data processing system searches for reference indication (i.e., link sources) in the received ML source data, and adds the page information for the linked objects to the ML source data. The page number on which the linked object is printed is printed after the printing of each link source term included when a ML source file, such as a home page. Consequently, when a home page is printed, for example, the user can easily arrive at the linked object from the link source in the printed document while the home page layout on the personal computer is kept intact.
