Abstract
When there is an inability to convey motion that is occurring in the frames of a video source by a full-frame-rate transmission, a surrogate effect, other than another form of motion, may be used as a compensation technique to better convey motion to a viewer. The surrogate effect employed may be a) fading, b) wiping, c) dissolving, d) blurring, e) enhancing the contrast, f) enhancing one or more colors, g) enhancing the brightness, h) scaling the image, and i) the like. How the surrogate effect is applied to any frame may be a function of one or more video frames. Optionally, more than one effect may be used in combination. Advantageously, a more continuous sense of motion is perceived by a viewer. In one embodiment of the invention, full-frame-rate video is initially available. A controller monitors the ability to transmit or display full-frame-rate video. In the event that it is determined that, ultimately, full-frame-rate video cannot be displayed to a user, the images of the frames that will be displayed are adjusted to incorporate a surrogate effect that helps to better convey the intended motion to the viewer. The surrogate effect applied may be selected as a joint function of the available frame rate and knowledge of the content, e.g., the specific type of motion, intended to be shown to the viewer.
