Abstract: System and method for providing personal videotelephony in which a plurality of videophones are connected to a communications network that is configured for transmitted video and audio communications. Each of the videophones typically includes a camera, display device, telephone keypad, speaker and microphone all of which are operatively connected. The videophones further include means for selectably receiving and transmitting signals over the communications network, which signals represent images and/or sound, and for selectably displaying the signals representing any received signals representing the images on the display screen, and for playing any received signals representing the sounds on said speaker. Means are also provided for selectably accessing a remote location, such as, but not limited to, another videophone, using information entered or selected by a user of the videophone, and to retrieve the signals representing the images and sounds being transmitted from the remote location.

Abstract: Display data comprising text and a background are processed. A combination of the text and background is evaluated against one or more objective criteria to provide one or more objective values. A determination is made whether the one or more objective values exceed one or more respective thresholds that are indicative of text-background combinations that are difficult to read. The text or the background or both are adjusted if any of the one or more thresholds is exceeded, so that the one or more thresholds are no longer exceeded after the adjusting.
