  • Publication number: 20120314233
    Abstract: A texture processing unit obtains smoothness information from a paper type specifying unit or a smoothness measuring device, and a lookup table is selected corresponding to the smoothness. An image area division unit divides off image signals of a predetermined hue area from among converted image signals. Predetermined hue area refers to a hue area in which, among multiple areas of different hues, a toner transfer failure tends to occur at concave portions that exist on a printing surface of a printing medium. The image signal processing unit applies the lookup table selected by the texture processing unit on the image signals that have been divided off, thereby increasing the toner amounts at concave portions.

  • Patent number: 8311471
    Abstract: An image forming apparatus forms a gloss mark with colored toner without using clear toner. This is accomplished by fixing an image composed of only part of the color toner required for forming an image, the rest of the required color toner being denoted as residual toner. Specifically, at an area of at which a decreased gloss is desired, an image is formed using a part of colored toner required for forming the image and fixed on a sheet, and then, applied to the sheet is the residual quantity of toner so as to be superimposed on the fixed colored toner.

  • Patent number: 8099100
    Abstract: The present invention provides a communication control system which can prevent unnecessary communication connections while ensuring user-friendliness when 1 to N communication is performed. The communication control system judges whether an area code of a mobile terminal and area codes of the other mobile terminals of the group match, and establishes 1 to N communication between the mobile terminal and the mobile terminals of which area codes match. As a result, when the users are contacted to meet, for example, the communication control system can prevent unnecessary communication connections without indiscriminately connecting the mobile terminals of users at distant locations for whom it is difficult to travel for a meeting. In addition, the communication destination mobile terminals are automatically selected based on the area code, user-friendliness can therefore be sufficiently ensured.
