Abstract

A method and a device for displaying an application image are provided, and the method includes the following steps: receiving a display request from a second operating system, and reading the application image stored in a storage area; judging whether it is required to process the application image through a window manager according to the configuration of the local image display system, and if required, sending the application image to the window manager, and sending the application image processed by the window manager to a display graphics library for processing; if not, directly sending the application image to the display graphics library for processing; and acquiring the location of the display memory through a display driver, sending the application image processed by the display graphics library to the display memory, and displaying the application image through the display memory. Using the solution, the application image of the installable operating system can be displayed in the local operating system.

Claims

1. A method for displaying an application image, which is applicable in a device comprising a first operating system and a second operating system with the first operating system comprising a memory comprising a storage area assigned to the application of the second operating system and which comprises:

receiving a display request from the second operating system and reading the application image stored in the storage area;

judging whether a window manager is needed to process the application image according to the configuration of a local image display system, and if the window manager is needed, transmitting the application image to the window manager and transmitting the application image processed by the window manager to a display graphic library for processing;

otherwise, transmitting the application image directly to the display graphic library for processing; and

acquiring the location of a frame buffer through a display driver, transmitting the application image processed by the display graphic library to the frame buffer, and displaying the application image through the frame buffer.

2. The method according to claim 1, further comprising:

before receiving the display request from the second operating system,

performing read and write operations, by the second operating system, in the storage area and transmitting the display request at the end of the operations to request a display process on the application image stored in the storage area.

3. The method according to claim 2, wherein performing the read and write operations by the second operating system in the storage area comprises:

receiving, by the second operating system, a User Interface, UI, update request from the application of the second operating system; and

processing, by the second operating system, the application image in response to the received UI update request.

4. The method according to claim 2, wherein transmitting by the second operating system the display request at the end of the operations comprises:

transmitting, by the second operating system, the display request in inter-process communication to request to perform UI update and display on the application image stored in the storage area.

5. The method according to claim 1, further comprising:

after displaying the application image through the frame buffer,

returning a display success message to the second operating system to have the second operating system perform display operations on the next frame.

6. An apparatus for displaying an application image, which is applicable in a device comprising a first operating system and a second operating system with the first operating system comprising a memory comprising a storage area assigned to the application of the second operating system and which comprises:

a proxy module configured to receive a display request from the second operating system, read the application image stored in the storage area, and judge whether a window manager is needed to process the application image according to the configuration of a local image display system, and if the window manager is needed, transmit the application image to the window manager and transmit the application image processed by the window manager to a graphic processing module;

otherwise, transmit the application image directly to the graphic processing module;

the graphic processing module configured to receive the application image from the proxy module and process the application image;

a display driver module configured to acquire the location of a frame buffer module and transmit the application image processed by the graphic processing module to the frame buffer module; and

the frame buffer module configured to receive the application image from the display driver module and display the application image.

7. The apparatus according to claim 6, wherein:

the proxy module is further configured to assign the storage area to the application of the second operating system in the memory of the first operating system after the application is run.

8. The apparatus according to claim 7, further comprising:

a running module configured to perform read and write operations in the storage area and transmit the display request to the proxy module at the end of the operations to request the proxy module for a display process on the application image stored in the storage area.

9. The apparatus according to claim 8, wherein:

the running module is further configured to receive a UI update request from the application of the second operating system, process the application image in response to the received UI update request and instruct the proxy module in inter-process communication to perform UI update and display on the application image stored in the storage area.

10. The apparatus according to claim 8 wherein:

the proxy module is further configured to return a display success message to the running module to have the second operating system perform display operations on the next frame.
