Syntax
INT is_SetExposureTime (HIDS hCam, double EXP, double* newEXP)
Description
Using is_SetExposureTime(), you can set the exposure time (in milliseconds). Since this value depends on the sensor timing, the exposure time actually used may slightly deviate from the value set here. The actual exposure time is returned by the newEXP parameter.
In free-running mode (is_CaptureVideo()), any modification of the exposure time will only become effective when the next image but one is captured. In trigger mode (is_SetExternalTrigger()), the modification will be applied to the next image.
For minimum and maximum exposure times as well as other sensor-based dependencies, please refer to Camera and Sensor Data chapter.

Input Parameters
hCam |
Camera handle |
EXP |
New desired exposure time For EXP=0.0, the exposure time is 1/frame rate. |
IS_GET_EXPOSURE_TIME |
Returns the current exposure time in the newEXP parameter. |
IS_GET_DEFAULT_EXPOSURE |
Returns the default exposure time. |
IS_SET_ENABLE_AUTO_SHUTTER |
Enables the auto exposure function. |
IS_GET_EXPOSURE_MIN_VALUE |
Returns the minimum available exposure time. |
IS_GET_EXPOSURE_MAX_VALUE |
Returns the maximum available exposure time. |
IS_GET_EXPOSURE_INCREMENT |
Returns the increment you can use to change the image exposure time. |
IS_GET_EXPOSURE_FINE_INCREMENT |
Returns a finer exposure time increment for some sensors. |
newEXP |
When setting a new exposure time via EXP: Returns the exposure time actually set (may deviate from desired exposure time) When passing other parameters via EXP: |
Return Values
IS_SUCCESS |
Function executed successfully |
IS_NO_SUCCESS |
General error message |
IS_NOT_SUPPORTED |
