Abstract
An augmented reality display alternates between displaying color frames and alpha frames to generate composite images for transparency control. A display processor includes two sets of buffers, each set including a color frame buffer and an alpha frame buffer. One set of buffers is used to provide data to the display while new video data is being written into the other set of buffers. The display processor switches which set of buffers is providing data and which set of buffers is having new video data written into them. By switching the alpha and color frame buffers in sets, a pair of color frame buffer and alpha frame buffer are always the current set of buffers to provide data as the output. If a frame drop occurs and the next color frame or alpha frame is not ready, the set of buffers is not switched to avoid disturbing flashing visual artifacts.
