Abstract:
1. A method comprising: receiving a first set of pixel values representing a portion of a first image frame at a first resolution, wherein the first set of pixel values represent a first pattern with a first rate of change; generating a second set of pixel values related to the first set of pixel values to represent the first pattern with a second rate of change, wherein the second pattern is related to the first pattern and the second rate of change is less than the first; and re-sampling the second set of pixel values to generate a portion of a second image frame, wherein the second image frame represents the first image frame at a second resolution, different from the first resolution; wherein generating the second set of pixel values includes replicating pixel values from the first set of pixel values; and wherein re-sampling the second set of pixel values includes generating alpha values to represent relative positions of pixels in the second image frame in relation to the pixels of the second set of pixel values.
