  • Publication number: 20050198586
    Abstract: A display control device for controlling a display of a display device responding to display processing from a plurality of processing units. A display controlling program controls the display device in response to at least one processing unit. The display controlling program receives a request from one processing unit to acquire one of predefined display areas, and determines whether to provide an authorization to acquire one of a plurality of predefined display areas in response to an acquisition request from the one processing unit. When a plurality of requests to acquire the same one of predefined display areas from a plurality of processing units are received, authorization is provided to a single processing unit that made one of the requests to acquire the same one of predefined display areas. The display device is instructed by a processor, based on the display controlling program. A memory, connected to the processor, stores the display controlling program.

  • Patent number: 6823324
    Abstract: A template storage unit stores a plurality of templates. A material data receiving unit receives material data. A combining rule storage unit stores a plurality of combining rules that each indicate a combining condition as a combination of attribute information, such as a type of material data and a version number, and a name of a template to be combined with when the combining condition is met. A combining instruction unit judges whether a combining condition of any of the combining rules is met or not and instructs a combining unit to combine the material data with the template when the combining condition is met.

  • Publication number: 20040217949
    Abstract: The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPU 12 processes display area acquisition requests from a plurality of processing units R1-Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R1-Rn. Each processing unit R1-Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R1-Rn after each processing unit R1-Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R1-Rn can be controlled appropriately.
