One embodiment is directed to a method that includes inspecting a frame of image data transmitted as a stream of pixels. At least one of the pixels in the stream is selected and the color of selected pixels is changed. The steps of inspecting, selecting, and changing the color of selected pixels may be performed as the data is transmitted. The frame may be transmitted for storing in a memory and the steps may be performed as the frame is stored in the memory. Alternatively, the frame may be transmitted from a memory and the steps may be performed as the frame is fetched from in the memory. The selected pixels may be pixels within a particular region of the frame or the selected pixels may have a particular color component value.
