Digital enhancement of streaming video and multimedia system
First Claim
1. A method for enhancing digital video such that an original small-frame digital video can be enlarged and displayed as a large-frame video with high resolution and quality, said original digital video including a sequence of image frames, each said image frame comprising limited number of columns and rows of pixels, said method comprising the steps of:
- increasing number of rows and columns of pixels of each said image frame; and
adjusting color characters of each new pixel created by said step of increasing;
said step of increasing including dividing each pixel of the image frame of said original video into a plurality of child pixels, said new pixels comprising said child pixels;
said step of adjusting comprising making the color characters of one of said child pixel equal to that of its parent pixel and determining the color characters of other child pixels of said parent pixel according to the color characters of the parent pixel and the neighboring pixels.

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.

3. A method for enhancing digital video such that an original small-frame digital video can be enlarged and displayed as a large-frame video with high resolution and quality, said original digital video including a sequence of image frames, each said image frame comprising limited number of columns and rows of pixels, said method comprising the steps of:
-
increasing number of rows and columns of pixels of each said image frame; and adjusting color characters of each new pixel created by said step of increasing; said step of increasing including dividing each pixel of the image frame of said original video into a plurality of child pixels, said new pixels comprising said child pixels; said step of adjusting including determining whether a pixel is an element-boundary pixel that contributes to the visual effect of a boundary of an image element within said image frame by evaluating amount of changes of color character differences between said pixel and its neighboring pixels. - View Dependent Claims (4, 5)
