  • Patent number: 7940418
    Abstract: A method of compensating for a light amount drift of a photosensor used in an image control device, wherein the photosensor includes a light emitting portion and a light receiving portion which projects light onto an image control mark formed on an intermediate transfer medium of a printer and detects an optical signal reflected by the image control mark, thereby controlling the quality of an image. In the compensation method, the light amount drift is calculated by projecting light on the intermediate transfer medium, detecting an amount of light reflected by the intermediate transfer medium, and comparing the detected light amount with a pre-set reference light amount. The detected light amount is then corrected to be substantially equal to the reference light amount.

  • Patent number: 7936481
    Abstract: A high-quality monochrome photographic image is formed using a high-resolution color ink-jet recording apparatus. When a monochrome mode is selected, density signals are produced such that they include at least one density signal corresponding to a chromatic color material and a density signal corresponding to an achromatic color material and having a value greater than the value of the at least one density signal corresponding to the chromatic color material. A slight recorded color deviation that can occur when the achromatic color material is recorded on a recording medium is compensated for by adding a small amount of chromatic color material having a hue which cancels out the recorded color deviation. Thus, a high-quality gray scale image is obtained without having recorded color deviation or color transition.

  • Patent number: 7936476
    Abstract: A system, method and computer readable medium for adjusting font pitch during a print process is disclosed. The method on a computer system includes observing a print command issued by an application. The method further includes generating an output file in response to the print command and modifying the output file to conform to a template. The method further includes determining the type of each character in the output file and adjusting the font pitch of characters in the output file based on their type. The method further includes sending the output file to an output destination. In one alternative, the method includes determining whether each character in the output file is at least one of a numerical character and an alphabetic character and 1) adjusting the font pitch of numerical characters to be fixed font pitch, and 2) adjusting the font pitch of alphabetic characters to be variable font pitch.

  • Patent number: 7929161
    Abstract: A printing control system includes a plurality of printing units, an image source, and a system processing unit. The image source provides a print job comprising a plurality of images to the system processing unit. The system processing unit receives the plurality of images in the print job from the image source, and calculates an image histogram for each image in the print job. The system processing unit then determines the similarity of the images in the print job by comparing the calculated histograms. The system processing unit then classifies the images into classes based on the comparison, and sends the classes of images to the printing units.

  • Patent number: 7929175
    Abstract: This invention relates an image printing apparatus capable of copying by executing enlargement/reduction (E/R) processing optimum to an instructed mode. According to the apparatus, a copy mode and an enlargement rate are input. The use priority order of each enlargement/reduction (E/R) unit of the apparatus is decided. The enlargement rate is distributed to each E/R unit in accordance with the copy mode, decided use priority order, and the E/R rate upper limit value of each E/R unit. An image is copied by causing each E/R unit to sequentially execute E/R processing in accordance with the distributed enlargement rate and the decided use priority order and causing a printing unit to print based on the image data that has undergone the E/R processing.

  • Patent number: 7916322
    Abstract: Techniques are disclosed for uploading content (such as a digital photograph) from a content upload device to a content server over a communications network, and for automatically forwarding the content from the content server to one or more remote destinations. A user of the content upload device may cause the content upload device to upload the content to the content server by initiating a single action, such as pressing a single button on the content upload device, and without providing information identifying the user to the content upload device. Upon receiving the content, the content server may add the content to a queue, referred to as a content outbox, associated with the user. The content server may automatically forward the content in the user's content outbox to one or more remote destinations specified by preferences associated with the user's content outbox.

  • Patent number: 7907708
    Abstract: In a communications network, voice and facsimile calls are established between first and second and second terminals via first and second media gateways in a communications network. Each gateway is capable of autonomous transitioning between a voice over IP (VoIP) call mode and a facsimile over IP (FoIP) call mode. A bearer path for the call is established via a media gateway controller. During call setup, the media gateways exchange confirmation of each gateway's capability to perform autonomous transitioning between VoIP and FoIP call modes. The call is established as a VoIP call, and, on a determination by the media gateways that a facsimile call is required, each media gateway autonomously transitions between its VoIP and FoIP call modes without the intervention of the media gateway controller.

  • Patent number: 7903268
    Abstract: As a user selects one of error recovery methods for each error category, and the selected method is stored in a memory. When an error occurs, an error recovery method corresponding to an error category of the error is detected. If the detected method is automatic print continuation, then the error is ignored and print operation is automatically continued. If the detected method is a recovery by user's operation, then an error message is displayed, and a procedure is performed in accordance with an instruction from the user.
