Hi: |
|
I am digitizing a NTSC signal and displaying on a PC video monitor. |
|
It is known that the display response of tubes is non-linear and is |
|
sometimes said to follow Gamma-Law. I am not certain if these |
|
non-linearities are "Gamma-corrected" before encoding NTSC signals |
|
or if the TV display is supposed to correct this. |
|
Also, if 256 grey levels, for example, are coded in a C program do |
|
these intensity levels appear with linear brightness on a PC |
|
monitor? In other words does PC monitor display circuitry |
|
correct for "gamma errrors"? |
|
Your response is much appreciated. |
|
Amjad. |
