KAYA Frame Grabbers Color Geometric Distortion Correction 7
4.3 Configuration steps
To configure the Color Distortion Corrector the following steps should be taken:
1. A color channel(Blue, Green or Red) should be selected by setting the
“ColorDistortionCorrectionSelector”
2. The mode of data loading should be set to “Normal” using the parameter
“ColorDistortionCorrectionLoadMode”. Afterwards, initial color channel address should be
selected by setting the “ColorDistortionCorrectionAddress”.
3. The desired mode of data loading should be defined using the
“ColorDistortionCorrectionLoadMode”.
4. If “Incremental” Load Mode is selected then data value should be written to
“ColorDistortionCorrectionValue”, each write will update the selected pixel color channel
correction value and increment the “ColorDistortionCorrectionAddress”;
On the other hand, if “Normal” Load Mode is selected, on each transection the
“ColorDistortionCorrectionAddress” should be updated and data value write/read could
follow, for selected pixel color channel correction address.
5. Corrector may be enabled/disabled using the “ColorDistortionCorrectionEnable” parameter.
Example code:
Color Geometric Distortion Correction
CAMHANDLE camHandle;
KYFG_SetGrabberValueEnum_ByValueName(camHandle,“ColorDistortionCorrectionSelector”,
“DistortCorrectChannelBlue”);
KYFG_SetGrabberValueEnum_ByValueName(camHandle,“ColorDistortionCorrectionLoadMode”,
“Normal”);
KYFG_SetGrabberValueInt(camHandle,“ColorDistortionCorrectionAddress”, 0);
KYFG_SetGrabberValueEnum_ByValueName(camHandle,“ColorDistortionCorrectionLoadMode”,
“Incremental”);
for(size_t iValueReg = 0; iValueReg < 4096; iV+)
{
int64_t value = ((int64_t)rand() % 256) - 128; // range of -128 up to +127
KYFG_SetGrabberValueInt(camHandle,“ColorDistortionCorrectionValue”, value);
}
KYFG_SetGrabberValueEnum_ByValueName(camHandle,“ColorDistortionCorrectionEnable”,
“Enable”);
