Abstract

An apparatus for processing visual information includes a controller to control display of information in an application window based on first visual information stored in a buffer and second visual information received from one or more sources. The controller outputs the first visual information for display in a first area of the application window and outputs the second visual information for simultaneous display in a second area of the application window. The first visual information is visual information that does not change between a first time and a second time, and the second visual information is visual information that changes between the first time and the second time. The controller may be different from a central processing unit of a host device.

Claims

1. An apparatus comprising:

a controller to control display of information in an application window based on first visual information stored in a buffer and second visual information from one or more sources,

the controller to output the first visual information from the buffer for display in a first area of the application window and to output the second visual information from the one or more sources for simultaneous display in a second area of the application window,

the first visual information to be visual information that does not change between a first time and a second time, and the second visual information to be visual information that changes between the first time and the second time.

2. The apparatus of claim 1, wherein the first time is to correspond to a first frame of the information to be displayed in the application window and the second time is to correspond to a second frame of the information to be displayed in the application window.

3. The apparatus of claim 2, wherein the first frame and the second frame are to be separated by a predetermined period of time or a predetermined number of frames.

4. The apparatus of claim 1, wherein the controller includes:

a comparator to compare the visual information to be stored in the buffer for the application window at the first time and the visual information to be received for the application window at the second time; and

a selector to select the first visual information for display in the first area of the application window and to select the second visual information for display in the second area of the application window based on the comparison.

5. The apparatus of claim 1, wherein the controller is coupled to:

a first visual information processor, and

a second visual information processor, wherein;

the first visual information processor is to correspond to a central processing unit (CPU) block and the controller is to switch control from the first processor to the second processor to output the visual information for display in the application window when a predetermined condition occurs.

6. The apparatus of claim 5, wherein the predetermined condition is to correspond to a predetermined period of time after call up of the application window.

7. The apparatus of claim 1, wherein the first visual information and the second visual information are to be selected from the group consisting of image information, video information, graphics information, and text information.

8. The apparatus of claim 1, wherein the first visual information is to include graphics or text information and the second visual information is to include image or video information.

9. The apparatus of claim 1, wherein the one or more sources are to correspond to one or more network cameras.

10. The apparatus of claim 1, wherein the application window is to be a Voice-over-Internet Protocol (VoIP) application window to perform video conferencing.

11. The apparatus of claim 1, wherein the one or more sources include:

a first camera to generate first video information, and

a second camera to generate second video information,

wherein the second visual information is to include the first and second video information from the first and second cameras.

12. A method for controlling display of information, comprising:

storing first visual information for an application window at a first time;

receiving second visual information for the application window at a second time;

comparing the first visual information and the second visual information; and

outputting first visual information for display in a first area of the application window and second visual information for simultaneous display in a second area of the application window, wherein the first visual information is included in the stored visual information and the second stored visual information is received from one or more sources different from a buffer storing the first visual information, and wherein the first visual information does not change between the first and second times and the second visual information changes between the first and second times.

13. The method of claim 12, wherein the first and second visual information is selected from the group consisting of image information, video information, graphics information, and text information.

14. The method of claim 12, wherein the one or more sources include one or more network cameras.

15. The method of claim 12, further comprising:

switching control from a first visual information processor to a second visual information processor when a predetermined condition occurs, wherein the first visual information processor corresponds to a central processing unit (CPU) block.

16. The method of claim 15, wherein the CPU block operates in a reduced power state after control is switched from the first visual information processor to the second visual information processor.

17. The method of claim 15, wherein the predetermined condition is to correspond to a predetermined period of time after call up of the application window.

18. The method of claim 12, wherein the first visual information includes graphics or text information and the second visual information includes image or video information.

19. The method of claim 12, wherein the application window is a Voice-over-Internet Protocol (VoIP) application window to perform video conferencing.

20. The method of claim 12, wherein the one or more sources include:

a first camera to generate first video information, and

a second camera to generate second video information,

wherein the second visual information includes the first and second video information from the first and second cameras.

21. A device comprising:

a display;

a controller to control display of information in an application window output on the display based on first visual information stored in a buffer and second visual information from one or more sources, the controller to output the first visual information from the buffer for display in a first area of the application window and to output the second visual information from the one or more sources for simultaneous display in a second area of the application window,

the first visual information to be visual information that does not change between a first time and a second time, and the second visual information to be visual information that changes between the first time and the second time.

22. The device of claim 21, wherein the first time is to correspond to a first frame of the information to be displayed in the application window and the second time is to correspond to a second frame of the information to be displayed in the application window.

23. The device of claim 22, wherein the first frame and the second frame are to be separated by a predetermined period of time or a predetermined number of frames.

24. The device of claim 21, wherein the controller includes:

a comparator to compare the visual information to be stored in the buffer for the application window at the first time and the visual information to be received for the application window at the second time; and

a selector to select the first visual information for display in the first area of the application window and to select the second visual information for display in the second area of the application window based on the comparison.

25. The device of claim 21, wherein the controller is to switch control from a first visual information processor to a second visual information processor when a predetermined condition occurs, wherein the first visual information processor corresponds to a central processing unit (CPU) block.

26. The device of claim 25, wherein the CPU block operates in a reduced power state after control is switched from the first visual information processor to the second visual information processor.
