Context-aware image processing

Abstract:

A method and apparatus for image processing. An image scaling circuit is configured to receive image data for a plurality of pixels corresponding to a first image. The image data includes color information and a transparency value for each of the plurality of pixels. The image scaling circuit updates the image data by selectively changing the color information for one or more of the pixels based at least in part on the transparency values. In updating the image data, the image scaling circuit may determine contextual information about the first image based at least in part on the transparency values. The image scaling circuit further generates an interpolated image based on the updated image data for the plurality of pixels. For example, the interpolated image may be a scaled version of the first image.
