Syntax
INT is_SetGamma (HIDS hCam, INT nGamma)
Description
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.
Notes
1. When the color format is set to Raw Bayer the gamma correction can not be used.
2. Typical values for gamma range between 1.6 and 2.2.
