Syntax
INT is_SetGamma (HIDS hCam, INT nGamma)
Description
This function is obsolete and should not be used anymore. We recommend to use the is_Gamma() function instead. |
is_SetGamma() enables digital gamma correction which applies a gamma characteristic to the image. When hardware color conversion is used on GigE uEye HE cameras the gamma correction is performed in the camera hardware as well. When the color conversion is performed in the PC (software conversion) the gamma correction is performed in software.
When the color format is set to Raw Bayer the gamma correction can not be used. |
Typical values for gamma range between 1.6 and 2.2. |
Input parameters
hCam |

nGamma |
