Syntax
INT is_DeviceFeature (HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
Description
Using is_DeviceFeature() you can configure special camera functions provided by specific uEye models:
•Enable/disable black reference columns, see uEye Cockpit: Advanced features
•Enable/disable black reference rows, see uEye Cockpit: Advanced features
|
The black level reference is currently supported by the following models: •UI-300x (reference rows) •UI-304x/UI-504x (reference rows) •UI-306x (reference rows) •UI-308x (reference rows) •UI-309x (reference rows) •UI-313x/UI-513x (reference rows) •UI-314x/UI-514x (reference rows) •UI-316x (reference rows) •UI-318x (reference rows) •UI-320x/UI-520x (reference rows) •UI-326x/UI-526x (reference rows) •UI-329x/UI-529x (reference rows) •UI-336x/UI-536x (reference columns) •UI-337x/UI-537x (reference columns) •UI-386x/UI-586x (reference rows) •UI-388x/UI-588x (reference rows) |
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. |
Status flags from DEVICE_FEATURE_MODE_CAPS
IS_DEVICE_FEATURE_CAP_BLACK_REFERENCE |
Displays the black level reference in the image which can be used to calibrate the black level. |
