Title: VIDEO DATA ROTATION METHOD AND SYSTEM
Abstract:
The present invention relates to a video data rotation method and system. The method for rotating video data comprises the following steps: obtaining an original display range corresponding to video data to be rotated which is on a display interface; calculating a target coordinate after a display coordinate corresponding to each pixel in the original display range is rotated according to a target rotation angle; determining a rotation correspondence relationship between a pixel and the target coordinate according to an original correspondence relationship between a pixel and a display coordinate in video data; filling each pixel in the video data to a target coordinate position corresponding to a pixel respectively according to the rotation correspondence relationship so as to rotate each pixel in said video data in the display interface; performance parameters of each pixel in the rotated video data remain unchanged, image quality corresponding thereto is well maintained, and a rotation process of each pixel in the video data is relatively simple to implement, while having high rotation efficiency.
