摘要：
A system positions an image with a plurality of lines on a display device. The system determines the number of black lines required to vertically center the image in a frame of the display device as m+n; displays m black lines using a first horizontal sync period at the start of each frame, the first horizontal sync period being less than the horizontal sync period of the display device; displays each line of the image; and displays n black lines using the second horizontal sync period until the end of the frame.
