View Patent ↗The present invention has an object of implementing a multi-window using an OS for smartphones that does not support multi-display. The display control apparatus according to the present invention is a display control apparatus using an operating system for smartphones, and includes: a window creator that creates a window for each of displays; a window allocator that allocates the windows to a plurality of applications; and a display controller that obtains respective display information items from the plurality of applications, and causes the displays to display the display information items according to the allocation of the windows, the displays corresponding to the respective windows. The plurality of applications include first applications defined by a specification of the operating system as applications for controlling display, and second applications defined by the specification as applications for not controlling display.
1. A display control apparatus using an operating system for smartphones, said display control apparatus comprising:
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs processes of
creating, for each of a plurality of display devices, a window that is a display area;
allocating said windows to a first application defined by a specification of said operating system as an application for controlling display, and a second application defined by said specification of said operating system as an application for not controlling display; and
obtaining respective display information items from said first application and said second application, and causing said plurality of display devices to display said display information items according to said allocation of said windows, said display devices corresponding to said respective windows,
wherein said first application is capable of allocating only one window,
said display information item obtained from said first application is partially clipped by said window allocated by said first application and is displayed on a first display device of said plurality of display devices, and
said display information item obtained from said second application is partially clipped by said window allocated by said second application and is displayed on a second display device of said plurality of display devices, and
wherein Android® is used as said operating system,
said first application is an activity application, and
said second application is a service application.
2. The display control apparatus according to claim 1 ,
wherein a view function in said service application prepares a display information item.
3. A display control method using an operating system for smartphones, said display control method comprising:
creating, for each of a plurality of display devices, a window that is a display area;
allocating said windows to a first application defined by a specification of said operating system as an application for controlling display, and a second application defined by said specification of said operating system as an application for not controlling display;
causing said first application and said second application to prepare respective display information items; and
obtaining said display information items from said first application and said second application, and causing said display devices to display said display information items according to said allocating of said windows, said display devices corresponding to said respective windows,
wherein said first application is an application capable of allocating only one window,
said display information item obtained from said first application is partially clipped by said window allocated by said first application and is displayed on a first display device of said plurality of display devices, and
said display information item obtained from said second application is partially clipped by said window allocated by said second application and is displayed on a second display device of said plurality of display devices, and
wherein Android® is used as said operating system,
said first application is an activity application, and
said second application is a service application.
