Syntax
INT is_Exposure (HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
Description
Using is_Exposure() you can set for the models UI-336x/UI-536x and UI-337x/UI-537x the dual exposure time.
|
Dual exposure and AOI If you want to use dual exposure and AOI simultaneously, you must take care that both 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_AOI() (if the image size is changed) 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 |
pParam |
Pointer to a function parameter, whose function depends on nCommand. |
cbSizeOfParam |
Size (in bytes) of the memory area to which pParam refers. |
UINT nRatio = 50;
INT nRet = is_Exposure(m_hCam, IS_EXPOSURE_CMD_SET_DUAL_EXPOSURE_RATIO, (void*)&nRatio, sizeof(nRatio));
