Abstract
Disclosed herein are methods and systems for enhancing digital streaming video. According to the present invention, the pixel resolution of the image frame of a digital streaming video, i.e., the numbers of pixels within said image frame, are artificially amplified by increasing the number of columns and rows of pixels therein. The color characters, such for examples as the color, contrast, brightness, saturation, hue, and/or luminescence, etc., of each newly created pixel or cell are obtained according to the color characters of those original neighboring pixels. The boundary or border of an image-element within said image frame may be improved by adjusting the color characters of those newly created or child pixels that are situated at or close to said image-element boundary. As a result, a small-frame digital video can be displayed as a large-frame high-resolution video having similar or even better image quality.
