Plane right-angle coordinate is set up in viewing area, and upper left corner of viewing area is (0,0), above-mentioned a height of vertical seat defined in it
Mark, a width of abscissa, therefore be to start filling original from the pixel position of viewing area (0,26) from (1920-1868)/2=26
(0,0) pixel of video to be played, (0,27) (1,27) (1,26) this 3 is filled with black pixel point, viewing area (0,
28) (0,1) pixel of former video to be played is filled in pixel position, by that analogy.Wherein viewing area 0 row~25 row and
The row of 1893 row~1919 are filled with black pixel point, you can the video to be played after extension is shown between two parties on the display terminal
Show.
Finally, the rgb value unification of the pixel of the video former to be played of (0,26) (0,28) Jia 2, such as former (R, G, B)
=(1,2,3) is (3,4,5) after then changing.The value-added effect of the above-mentioned pixel to each pixel in former video to be played is to carry
The brightness of former video to be played is risen, if not highlighted, the image quality of whole video can be influenceed after black pixel point is filled, although
Highlighting can be lifted power consumption, but on the basis of replacing by the way of existing use color pixel cell using black pixel point, it is whole
Body is still able to reduce power consumption.Therefore aforesaid operations enable to ensureing that image quality is low close to reducing in the case of original image quality
