摘要
A conversion method includes: obtaining two R's, two G's and two B's sub-pixel values having interleaved positions from four pixels of the RGB format; obtaining four Y-luminance value, one U-chrominance value and one V-chrominance value of the YUV format according to the obtained sub-pixel values. The Y-luminance values of the first, second, third and fourth pixels in the YUV format are calculated from R's of the first pixel, G's of the second pixel, G's of the third pixel and B's sub-pixel value of the fourth pixel respectively. The U-chrominance value of the first pixel is calculated from B's of the first pixel, R's of the first pixel and the G's sub-pixel value of the third pixel. The V-chrominance value of the first pixel is calculated from the R of the fourth pixel, G of the second pixel and B of the fourth pixel.
