the Y position and the AOI height are a multiple of 4. If this is not the case, the dual
exposure cannot be activated. If the dual exposure is activated, you must observe the
changed step width.
Note on dependencies on other settings
The use of the following functions will affect the exposure time:
is_PixelClock()
is_SetOptimalCameraTiming()
is_SetFrameRate()
is_AOI() (if the image size is changed)
is_SetSubSampling()
is_SetBinning()
Changes made to the image size, the frame rate or the pixel clock frequency also
affect the exposure time. For this reason, you need to call is_Exposure() again after
such changes.
Note on new driver versions
Newer driver versions sometimes allow an extended value range for the exposure
time setting. We recommend querying the value range every time and set the
exposure time explicitly.
The nCommand input parameter is used to select the function mode. The pParam input parameter
depends on the selected function mode. If you select functions for setting or returning a value,
pParam contains a pointer to a variable of the UINT type. The size of the memory area to which
pParam refers is specified in the cbSizeOfParam input parameter.
Input parameters
hCam
Camera handle
nCommand
IS_EXPOSURE_CMD_GET_DUAL_EXPOSURE_RATIO_D
EFAULT
Returns the default ratio for dual exposure.
IS_EXPOSURE_CMD_GET_DUAL_EXPOSURE_RATIO_R
ANGE
Returns the range for dual exposure
(IS_RANGE_S32).
IS_EXPOSURE_CMD_GET_DUAL_EXPOSURE_RATIO
Returns the ratio between exposure times for
dual exposure.
IS_EXPOSURE_CMD_SET_DUAL_EXPOSURE_RATIO
Sets the ratio between exposure times for dual
exposure. For model / or / select a percental
value between 10 and 100. E.g. 50 means that
odd lines are exposed at the selected exposure
time and even lines are exposed with 50% of
the selected exposure time (Example).
Note: The dual exposure cannot be used when
the camera is operated with minimum exposure
time.
pParam
Pointer to a function parameter, whose function
depends on nCommand.
cbSizeOfParam
Size (in bytes) of the memory area to which
pParam refers.
