Syntax

INT is_SetTimeout (HIDS hCam, UINT nMode, UINT Timeout)

Description

Using is_SetTimeout(), you can change user-defined timeout values of the uEye API. If no user-defined timeout is set, the default value of the uEye API is used for the relevant timeout.

For further information, please refer to the How to proceed: Timeout values for image capture section.

hint_info

The user-defined timeout only applies to the specified camera at runtime of the program.

Timeout for hardware trigger

If you set a user-defined timeout value, we recommend the following formula for calculating the timeout:

Timeout = (max. time between trigger signals + max. exposure time + frame duration + trigger delay) * factor

•Max. time between trigger signals: the maximum interval between two hardware trigger signals in the application

•Max. exposure time: the maximum exposure time in the application

•Frame duration: 1/frame rate

•Trigger delay: Trigger delay which can be set using is_SetTriggerDelay().

•Factor: The factor should have a value between 1.5 and 2. The application is blocked too long with a too large value and with a too small value you may lost images.

Input parameters

hCam

Camera handle

nMode

Selects the timeout value to be set

IS_TRIGGER_TIMEOUT

Sets the timeout value for triggered image capture

Timeout

Timeout value in 10 ms.

Value range [0; 4...429496729] (corresponds to 40 ms to approx. 1193 hours)

0 = use default value of the uEye API

For 1...3, the value 4 is used.

Return values

IS_CANT_COMMUNICATE_WITH_DRIVER

Communication with the driver failed because no driver has been loaded.

IS_CANT_OPEN_DEVICE

An attempt to initialize or select the camera failed (no camera connected or initialization error).

IS_INVALID_CAMERA_HANDLE

Invalid camera handle

IS_IO_REQUEST_FAILED

An IO request from the uEye driver failed. Possibly the versions of the ueye_api.dll (API) and the driver file (ueye_usb.sys or ueye_eth.sys) do not match.

IS_NO_SUCCESS

General error message

IS_NOT_SUPPORTED

The camera model used here does not support this function or setting.

IS_SUCCESS

Function executed successfully
