Abstract
Systems and methods for enhancing display of textual information in a video stream displayed on a portable device. In one aspect textual information is identified in frames of a video stream and is enhanced to improve visual readability of the textual information. The textual information may be enhanced by enlarging portions of frames of the video stream that include the textual information to overlay other portions of the display screen. The textual information may also be enhanced by converting the textual information in the frames of the video stream into character glyphs for display on the display screen of the portable device. Identification and enhancement of the textual information may be performed within the portable device or within systems external to the portable device and may be performed by automated procedures or responsive to user input on the portable device.
