| titleOfInvention | Improved bicubic interpolation video scaling method |
| abstract | The invention discloses an improved bicubic interpolation video scaling method which comprises the following steps of: firstly, receiving a video signal to be processed; secondly, judging whether the video signal is required to be subjected to amplifying processing or scaling processing, if the video signal is subjected to the amplifying processing, carrying out sharpening filter processing on the received video signal, then carrying out bicubic interpolation processing on the video signal subjected to sharpening filter processing and finally outputting the video signal subjected to bicubic interpolation processing, and otherwise, carrying out bicubic interpolation processing on the received video signal first, then carrying out sharpening filter processing on the video signal subjected to bicubic interpolation processing and finally outputting the video signal subjected to sharpening filter processing. According to the improved bicubic interpolation video scaling method disclosed by the invention, the mode of carrying out sharpening filter processing by adopting a combined filter, a log filter or a laplace filter is preferably considered; a preposed sharpening filter is used for carrying out amplifying processing on an video image and a postposed sharpening filter is used for carrying out minifying processing on the video image, so that the quality of bicubic interpolation video scaling can be improved, edge blur and sawtooth in the scaling processing process of the video image can be effectively overcome and the video image with better image quality can be obtained. |
