Syntax
INT is_SetBlCompensation (HIDS hCam, INT nEnable, INT offset, INT reserved)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_Blacklevel()
function instead (see also Obsolete functions ).
is_SetBlCompensation() enables the black level correction function which might improve the image quality
under certain circumstances. By default, the sensor adjusts the black level value for each pixel automatically. If the
environment is very bright, it can be necessary to adjust the black level manually by the offset parameter.
