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