20 *Notes: * t613 + tas5130A
21 * * Focus to light do not balance well as in win.
22 * Quality in win is not good, but its kinda better.
23 * * Fix some "extraneous bytes", most of apps will show the image anyway
24 * * Gamma table, is there, but its really doing something?
25 * * 7~8 Fps, its ok, max on win its 10.
