Abstract

Various methods for display framebuffer processing are provided. One example method include determining, via a processor, that update criteria associated with a display region has been satisfied, and comparing current frame data for the display region to subsequent frame data for the display region to determine frame data changes associated with the display region. In this regard, the comparing is performed in response to the update criteria being satisfied. The example method may also include facilitating presentation of the frame data changes within the display region on a display. Similar and related example methods and example apparatuses are also provided.

Claims

1. A method comprising:

determining, via a processor, that update criteria associated with a display region has been satisfied;

comparing current frame data for the display region to subsequent frame data for the display region to determine frame data changes associated with the display region, wherein comparing is performed in response to the update criteria being satisfied; and

facilitating presentation of the frame data changes within the display region on a display, the display region being less than an entire area of the display.

2. The method of claim 1, wherein determining that the update criteria has been satisfied includes determining that a timer threshold has been passed.

3. The method of claim 1, wherein determining that the update criteria has been satisfied includes determining that user input has been received via a user interface.

4. The method of claim 1, wherein determining that the update criteria has been satisfied includes determining that a context of an application associated with the current frame data has changed.

5. The method of claim 1, wherein determining that the update criteria has been satisfied includes determining that frame data changes associated with another display region have occurred.

6. The method of claim 1, wherein determining that the update criteria associated with the display region has been satisfied includes referencing the update criteria and an area of the display region stored as meta-data for an associated application.

7. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

determine that update criteria associated with a display region has been satisfied;

compare current frame data for the display region to subsequent frame data for the display region to determine frame data changes associated with the display region, wherein the current frame data is compared in response to the update criteria being satisfied; and

facilitate presentation of the frame data changes within the display region on a display, the display region being less than an entire area of the display.

8. The apparatus of claim 7, wherein the apparatus caused to determine that the update criteria has been satisfied includes being caused to determine that a timer threshold has been passed.

9. The apparatus of claim 7, wherein the apparatus caused to determine that the update criteria has been satisfied includes being caused to perform determine that user input has been received via a user interface.

10. The apparatus of claim 7, wherein the apparatus caused to determine that the update criteria has been satisfied includes being caused to determine that a context of an application associated with the current frame data has changed.

11. The apparatus of claim 7, wherein the apparatus caused to determine that the update criteria has been satisfied includes being caused to determine that frame data changes associated with another display region have occurred.

12. The apparatus of claim 7, wherein the apparatus caused to determine that the update criteria associated with the display region has been satisfied includes being caused to reference the update criteria and an area of the display region stored as meta-data for an associated application.

13. The apparatus of claim 7, wherein the apparatus comprises a mobile terminal;

and wherein the apparatus further comprises user interface circuitry and user interface software configured to facilitate user control of at least some functions of the mobile terminal through the use of a display and configured to respond to user inputs, and a display and display circuitry configured to display at least a portion of a user interface of the mobile terminal, the display and the display circuitry configured to facilitate user control of at least some functions of the mobile terminal.

15. A computer program product comprising at least one computer-readable storage medium having executable computer-readable program code instructions stored therein, the computer-readable program code instructions for causing an apparatus to:

determine that update criteria associated with a display region has been satisfied;

compare current frame data for the display region to subsequent frame data for the display region to determine frame data changes associated with the display region, wherein the current frame data is compared in response to the update criteria being satisfied; and

facilitate presentation of the frame data changes within the display region on a display, the display region being less than an entire area of the display.

14. The apparatus of claim 18 further comprising a communications interface configured to transmit the frame data changes to the display, the display being a remote device display.

16. The computer program product of claim 15, wherein the computer-readable program code instructions for causing the apparatus to determine that the update criteria has been satisfied include computer-readable program code instructions for causing the apparatus to determine that a timer threshold has been passed.

17. The computer program product of claim 15, wherein the computer-readable program code instructions for causing the apparatus to determine that the update criteria has been satisfied include computer-readable program code instructions for causing the apparatus to determine that user input has been received via a user interface.

18. The computer program product of claim 15, wherein the computer-readable program code instructions for causing the apparatus to determine that the update criteria has been satisfied include computer-readable program code instructions for causing the apparatus to perform determine that a context of an application associated with the current frame data has changed.

19. The computer program product of claim 15, wherein the computer-readable program code instructions for causing the apparatus to determine that the update criteria has been satisfied include computer-readable program code instructions for causing the apparatus to determine that frame data changes associated with another display region have occurred.

20. The computer program product of claim 15, wherein the computer-readable program code instructions for causing the apparatus to determine that the update criteria associated with the display region has been satisfied include computer-readable program code instructions for causing the apparatus to reference the update criteria and an area of the display region stored as meta-data for an associated application.
