Syntax
INT is_InitCamera (HIDS* phCam, HWND hWnd)
Description
is_InitCamera() starts the driver and establishes the connection to the camera. After successful initialization, this function assigns the camera handle. All subsequent functions require this handle as the first parameter.
When using Direct3D or OpenGL for image display, you can pass a handle to the output window.
Starter firmware for GigE uEye cameras When you are using these camera models, initialization will be aborted with an error message if the camera's starter firmware is not compatible with the installed driver. To initialize the camera, you have to write the proper starter firmware to the camera first. This is done using the is_InitCamera() function with corresponding parameter setting (see Input parameters table). Updating the firmware can take up to 20 seconds. It is important not to disconnect the camera from the PC or power supply during this time. Otherwise, malfunctions could occur in the camera. Camera models GigE uEye SE/RE only: f you have initialized the camera with a driver version earlier than 3.40, you need to update the camera firmware manually using the IDS Camera Manager. Driver versions 3.40 and higher support automatic firmware updates. |
Note on multi-camera environments When using multiple cameras in parallel operation on a single system, you should assign a unique camera ID to each camera. To initialize or select a camera with is_InitCamera(), the phCam handle must previously have been set to the desired camera ID. To initialize or select the next available camera without specifying a camera ID, phCam has to be preset with 0. |
phCam |
Pointer to the camera handle When you call this function, the pointer value has the following meaning: 0: The first available camera will be initialized or selected. 1-254: The camera with the specified camera ID will be initialized or selected. |
*phCam | |
The camera is opened using the device ID instead of the camera ID. For details on device ID please refer to the is_GetCameraList() chapter. |
*phCam | |
During initialization of the camera, this parameter checks whether a new version of the starter firmware is required. If it is, the new starter firmware is updated automatically. To ensure backward compatibility of applications, always call is_InitCamera() without the IS_ALLOW_STARTER_FW_UPLOAD parameter first. Only if an error occurs, call the function with this parameter set (see Example below). |
hWnd |
Pointer to the window where the Direct3D image will be displayed If hWnd = NULL, DIB mode will be used for image display. |

Error opening a Windows registry key |
IS_CANT_READ_REGISTRY |
Error reading settings from the Windows registry |
IS_CAPTURE_RUNNING |
A capturing operation is in progress and must be terminated first. |
IS_CRC_ERROR |
A CRC error-correction problem occurred while reading the settings. |
IS_DEVICE_ALREADY_PAIRED |
The device is already in use by the system or is being used by another system. (Camera was opened and paired to a device). |
IS_DEVICE_NOT_COMPATIBLE |
The device is not compatible to the drivers. |
IS_DR_CANNOT_CREATE_SURFACE |
The image surface or overlay surface could not be created. |

IS_ERROR_CPU_IDLE_STATES_CONFIGURATION |
The configuration of the CPU idle has failed. |
IS_FILE_WRITE_OPEN_ERROR |
File cannot be opened for writing or reading. |
IS_INCOMPATIBLE_SETTING |
Because of other incompatible settings the function is not possible. |
IS_INVALID_BUFFER_SIZE |
The image memory has an inappropriate size to store the image in the desired format. |
IS_INVALID_CAMERA_TYPE |
The camera type defined in the .ini file does not match the current camera model. |
IS_INVALID_CAPTURE_MODE |
The function can not be executed in the current camera operating mode (free run, trigger or standby). |
IS_INVALID_DEVICE_ID |
The device ID is invalid. Valid IDs start from 1 for USB cameras, and from 1001 for GigE cameras. |
IS_INVALID_EXPOSURE_TIME |
This setting is not available for the currently set exposure time. |
IS_INVALID_CAMERA_HANDLE |
Invalid camera handle |
IS_INVALID_IP_CONFIGURATION |
The configuration of the IP address is invalid. |
IS_INVALID_MEMORY_POINTER |
Invalid pointer or invalid memory ID |
IS_INVALID_MODE |
Camera is in standby mode, function not allowed |
IS_INVALID_PARAMETER |
One of the submitted parameters is outside the valid range or is not supported for this sensor or is not available in this mode. |
IS_INVALID_PIXEL_CLOCK |
This setting is not available for the currently set pixel clock frequency. |
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_NETWORK_CONFIGURATION_INVALID |
The configuration of the network card is invalid. |
IS_NETWORK_FRAME_SIZE_INCOMPATIBLE |
The settings for the image size of the camera are not compatible to the PC network card. |
IS_NO_ACTIVE_IMG_MEM |
No active image memory available. You must set the memory to active using the is_SetImageMem() function or create a sequence using the is_AddToSequence() function. |
IS_NO_IMAGE_MEM_ALLOCATED |
The driver could not allocate memory. |
IS_NO_IR_FILTER |
No IR filter available |
IS_NO_SUCCESS |
General error message |
IS_NOT_CALIBRATED |
The camera does not contain any calibration data. |

No memory could be allocated. |
IS_SEQUENCE_BUF_ALREADY_LOCKED |
The memory could not be locked. The pointer to the buffer is invalid. |
IS_STARTER_FW_UPLOAD_NEEDED |
The camera's starter firmware is not compatible with the driver and needs to be updated. |
IS_SUCCESS |
Function executed successfully |
IS_SUBNET_MISMATCH |
The subnet of the camera and PC network card are different. |
IS_SUBNETMASK_MISMATCH |
The subnet mask of the camera and PC network card are different. |
IS_TIMED_OUT |
A timeout occurred. An image capturing process could not be terminated within the allowable period. |
IS_TRIGGER_ACTIVATED |
The function cannot be used because the camera is waiting for a trigger signal. |
