Patent Images

1. A method of updating images displayed on a display device, the method comprising:

  • identifying image resource data associated with an update event for a first image from a basic recording space when the update event for the first image occurs;

    loading the identified image resource data in a buffer space including a plurality of buffers, in which the image resource data are loaded in rotation on the buffer by frame, respectively;

    generating the first image at a first frame rate by sequentially rendering the loaded image resource data;

    generating a second image associated with an update event for the second image at a second frame rate when the update event for the second image occurs, the generation of the second image being substantially independent from the generation of the first image such that image resource data of the second image is not loaded in the buffer space;

    compositing the first image with the second image; and

    updating at least a portion of the display device to display the composite image,wherein the second image is generated without being rendered.
