  • Patent number: 10002111
    Abstract: A cellular phone apparatus includes a screen A and a screen B. In a state where an overview of data for a screen with a large amount of information is guide displayed on the screen B (screen for user selection), every time an arbitrary content is selected, the cellular phone apparatus changes the data for the screen with the large amount of information to data for a screen with a small amount of information while arranging and displaying the selected content obtained via a Web server on the screen A. Accordingly, when data for the screen with the large amount of information is changed to data for the screen with the small amount of information in response to an instruction on a user side, a change that reflects the intentions of the user can be easily achieved.
