Based on the color space conversion model  the point spread functions of the image motion on each plane of YUV422 image can be achieved. The U  V plane of YUV422 images are combined to form a new UV plane which has the same size as Y plane. Then  the Y  UV plane are packed into a two dimensional complex array which can be transformed directly by FFT and result a composite frequency spectrum. Wiener filter is applied to filter Y  UV spectrums separated from the composite spectra. On Graphics Processing Unit (GPU) platform  the proposed algorithm can restore a 1024x1024 24-bit motion-blurred color image in 7.95ms  and the PSNR of the restored image is 27.12 which reveals a good restoration performance. 2009 IEEE.
