Abstract
A method comprises: obtaining two depth values from each of a first pixel depth value and a fourth pixel depth value, and obtaining one depth value from each of a second pixel depth value and a third pixel depth value; and assigning the two depth values obtained from the first pixel depth value to the R-subpixel and B-subpixel values of the first pixel, assigning the depth value obtained from the second pixel depth value to the R-subpixel, G-subpixel and B-subpixel values of the second pixel, assigning the depth value obtained from the third pixel depth value to the R-subpixel, G-subpixel and B-subpixel values of the third pixel, and assigning the two depth values obtained from the fourth pixel depth value to the G-subpixel value of the first pixel and the R-subpixel, G-subpixel and B-subpixel values of the fourth pixel.
