System and method for calculating an optimum display size for a visual object

Abstract

A method and system can automatically select the optimal size of a visual object that can be displayed on an display device. For example, the present invention can determine the best or optimum size to display a visual object received from a computer network to a computer screen such that image degradations due to compression or transmission defects are less noticeable or perceivable. Typically, the best or optimum size to display a visual object can comprise a size that is also the maximum in which the visual object can be displayed without any degradations or defects.

Problems solved by technology

While the aforementioned compression techniques may permit the transmission of visual objects over a computer network, such compression techniques can introduce artifacts or distortion in the video as a direct result of the compression techniques.

For example, MPEG-1 encoding can introduce artifacts such as blockiness, mosquito noise, color bleeding, and shimmering effects within the video in addition to a lack of detail in quantization effects in audio.

While the effects of the compression techniques on the video segments of a multimedia presentation may be negligible in some instances, typically the artifacts and distortion generated by the compression techniques become quite apparent to a user when a visual object such as video is enlarged on a display device.

Therefore, some conventional media players do not even permit the selection for enlarging a video segment.

In addition to compression related artifacts discussed above, there also exists packet loss related artifacts that are a result of the transmission speed of a multimedia segment.

For example, low bit rates can also contribute to the artifacts or distortion when compressed video is decoded.

However, as noted above, a balance should be struck between displaying a visual object large enough to be comfortably viewed by a user while at the same time, displaying the visual object at a size that does not permit image degradations due to compression or transmission to be noticeable or easily perceived by the user.
