Patent ID: 8149337

Claim:
A video processing apparatus comprising: an input module configured to input a video signal; a video processor including a sharpening processor configured to apply sharpening processing to pixels in a horizontal direction and pixels in a vertical direction, which are included in the video signal, and a correction module configured to apply image blur correction to the pixels in the horizontal direction and the pixels in the vertical direction based on an imaging model function; and a detector configured to detect a type of the video signal from the video signal whether corresponding graphics or other than graphics, wherein the sharpening processor comprises a sharpening horizontal filter for the sharpening processing to the pixels in the horizontal direction and a sharpening vertical filter for the sharpening processing to the pixels in the vertical direction, applies the sharpening processing by the sharpening horizontal filter and the sharpening vertical filter based on a first parameter depending on a graphics detection result by the detector, and applies the sharpening processing by the sharpening horizontal filter based on the first parameter and the sharpening processing by the sharpening vertical filter based on a second parameter depending on a detection result other than the graphics detection result by the detector, the first parameter is used to vary a sharpening effect depending on a case in which the video signal includes few high-frequency components or a case in which the video signal includes many high-frequency components, and the second parameter is obtained by correcting the first parameter based on the imaging model function, the correction module is configured to apply the image blur correction to the pixels in the horizontal direction based on the imaging model function and to apply the image blur correction to the pixels in the vertical direction by the sharpening vertical filter based on the second parameter depending on the detection result other than the graphics detection result by the detector.
