*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.
