  • Patent number: 8514256
    Abstract: The quality of an image recorded on electronic paper is improved. Specifically, electronic paper for displaying an image is supplied in a region in which an electric field is generated in the thickness direction of the electronic paper, the electronic paper having charged color particles and being used for displaying an image as a result of charged color particles migrating in the thickness direction. Voltage for generating an electric field in the region is controlled by a voltage control section so that the value of the voltage varies together with time. The quality of an image recorded on electronic paper can thereby be improved.

  • Patent number: 8406734
    Abstract: When an application activation instruction is input, it is decided whether the application is expected to access a high-level protection resource or low-level protection resource (step S31). If the decision is affirmative, display is done to prompt the user to select whether to permit activation of the application (step S32). When the user inputs an activation permission instruction, the application is activated (steps S33 to S36). As a result, only when the user permits an application, which is expected to access a high-level protection resource or low-level protection resource, to access a predetermined resource immediately before its execution, the application is executed. Hence, the basic processing part and application can operate in cooperation with each other while limiting access to various kinds of resources by the application in a reasonable range.
