Abstract
The present invention relates to a video signal processing method and a video signal processing apparatus. The video signal processing apparatus receives a picture datum, which includes M×N pixel data, wherein a scan orientation of the pixel data includes M pixel data. The video signal processing apparatus includes a horizontal scaling unit and a timing control unit. The horizontal scaling unit scales the pixel data of the scan orientation of the picture datum to obtain P pixel data. The timing control unit transfers the P pixel data to a scan-line signal of the video signal, determines the number of times of outputting the scan-line signal according to a ratio of Q to N, sequentially outputs the scan-line signal according to the number of times of outputting the scan-line signal and thus outputs the video signal with a resolution of P×Q.
