发明名称 IMAGE ROTATION IN OPPONENT COLOR SPACE
摘要 An image is rotated in opponent color space, such as L*a*b* or Y CB CR color space, by inputting the opponent color space image data, subsampling the opponent color space image data, and addressing the subsampled opponent color space image data into an output configuration corresponding to a specified rotation angle. For 90° and 270° rotation, the opponent color space image data is scaled before being addressed. This eliminates distortion of the rotated image, while allowing real-time rotation of the image in hardware.
