4.3.86 is_SetGamma
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.
Input parameters
Gamma value to be set, multiplied by 100
(Range: 1…1000.
Default = 100, corresponds to a gamma value of 1.0)
Returns the current setting.
Return values
When used with
IS_GET_GAMMA
IS_CANT_COMMUNICATE_WITH_DRIVER
Communication with the driver failed because no driver
has been loaded.
An attempt to initialize or select the camera failed (no
camera connected or initialization error).
One of the submitted parameters is outside the valid
range or is not supported for this sensor or is not
available in this mode.
An IO request from the uc480 driver failed. Possibly the
versions of the uc480_api.dll (API) and the driver file
(uc480_usb.sys) do not match.
The camera model used here does not support this
function or setting.
