4. 将信号输入到白场,保持R gain, B gain,R off ,B off , G off不变,调节G gain,寻找最亮 点。 操作方法:输入100%全白场信号,向上调节G gain,到亮度不再改变时即找到了亮度最亮点,由于 初始值可能已经处于最亮点,如果发现从初始值向上调节后不改变亮度,则向下调节,直到亮度变小 后,再向上调节找最亮点。 5. 再将6个参数置为初始值,参照G gain 的调节方法,单独调节R gain 和B gain.,寻找最亮点。一 般来说,R Gain,B gain 的最大值和G Gain 相同即可。 6. 寻找最暗点 操作方法:输入黑场信号(幅度为0%的白场信号),保持完成第5步得到的参数值,向下调节G off,到 亮度不再改变时即找到最暗点,如果G off从31开始往下调就没有起作用,则认为最暗点就是31。 7. 调整暗场亮度 经过第4步和第5步,记录当前屏幕的亮度,再输入25%幅度的全白场信号,等量调节R offset, G offset, B offset.一般是向上调至亮度区间(最大亮度/16,最亮点亮度/21)。...

Procedure: Input 100% white signal, increase G gain until the bright don’t change. This is the brightest point. For the default may be the brightest value, the bright don’t change even increase default. In this case, first decrease G gain until the bright get down, then increase it. Then set R gain, G gain, B gain, R off, G off, B off to the default, adjust R gain and B gain as same as the G gain shown above.
