Dear Sir:
I tried to apply a user-defined gamma table in RAM.
But the result is not good.
It will work, but I can not get a result as good as the ROM table.
There are two questions:
(1) There seems to be a problem when I create the gamma table's maximum offset as 1023.
The high light area will become black and blue. It looks like overshoot.
I has to reduce the maximum offset to 511 to keep the image look normal.
(2) What is the gamma value of the ROM gamma table?
The result of ROM gamma table is good, but I want to make it even better.
I tested RAM gamma table in 0.8, 0.7,0.6... to 0.1. But nothing better is available.
Any comment will be appreciated.
Best regards,
Ray
