Patent ID: 7663636

Claim:
An apparatus for automatically analyzing digital video quality, comprising: a video analyzing unit configured to analyze a texture attribute of an input video and to analyze a color attribute of the input video to obtain a texture attribute analysis result and a color attribute analysis result, respectively, and assign the texture attribute analysis result and the color attribute analysis result to a main component analysis result and a minor analysis result based, upon the existence of a reference video, the textural attribute analysis result and the color attribute analysis result ranging from about zero, the lowest quality, to about 100, the highest quality; and a result displaying unit configured to determine the existence of the reference video; wherein when the reference video exists, the result displaying unit is configured: to determine the texture attribute analysis result as a main component analysis result and the color attribute analysis result as a minor component analysis result, and to display the determined analysis results on a screen in a form of numerical values and graphs together with the input video; wherein, when the reference video does not exist, the results displaying unit is configured to determine the texture attribute analysis result as the minor component analysis result and the color attribute analysis result as the main component analysis result, respectively, and to display the determined analysis results on the screen in a form of numerical values and graphs together with the input video; and wherein a final video quality is determined based upon the following equation: Final Video Quality ={kΣ(main component analysis result)+(1−k)Σ(minor component analysis result)}/3; where k is a predetermined importance factor.
