Syntax
INT is_SetSubSampling (HIDS hCam, INT mode)
Description
Using is_SetSubSampling(), you can enable subsampling mode both in horizontal and in vertical directions. This allows you to reduce the image size in the subsampling direction without scaling down the area of interest. In order to simultaneously enable horizontal and vertical subsampling, the horizontal and vertical subsampling parameters can by linked by a logical OR.
|
Note that binning or subsampling cannot be activated if the AOI size is set to the minimum value. |
Some monochrome sensors are limited by their design to mere color subsampling. In case of fine image structures, this can result in slight artifacts.
The adjustable subsampling factors of each sensor are listed in Camera and sensor data chapter.
Some sensors allow a higher pixel clock setting if binning or subsampling has been activated. If you set a higher pixel clock and then reduce the binning/subsampling factors again, the driver will automatically select the highest possible pixel clock for the new settings.

This function is currently not supported by the following camera models: •UI-1007XS |
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and exposure time. After executing is_SetSubSampling(), calling the following functions is recommended in order to keep the defined camera settings:
•If you are using the uEye camera's flash function: is_IO()

Return values
When used with IS_GET_SUBSAMPLING |
Current setting: Returns the defined constants using "OR" from ueye.h, e.g. IS_SUBSAMPLING_2X_HORIZONTAL |
When used with IS_GET_SUBSAMPLING_FACTOR_VERTICAL IS_GET_SUBSAMPLING_FACTOR_HORIZONTAL |
Current setting: Returns the current factor as integer value (2, 3, 4, 5, 6, 8, 16) |
When used with IS_GET_SUBSAMPLING_TYPE |
Current setting: Returns IS_SUBSAMPLING_COLOR if the camera uses color-proof subsampling, else IS_SUBSAMPLING_MONO |
When used with IS_GET_SUPPORTED_SUBSAMPLING |
Returns the supported subsampling modes linked by logical ORs |
IS_BAD_STRUCTURE_SIZE |
An internal structure has an incorrect size. |
IS_CANT_ADD_TO_SEQUENCE |
The image memory is already included in the sequence and cannot be added again. |
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_CAPTURE_RUNNING |
A capturing operation is in progress and must be terminated first. |
IS_DR_CANNOT_CREATE_SURFACE |
The image surface or overlay surface could not be created. |
IS_DR_CANNOT_CREATE_TEXTURE |
The texture could not be created. |
IS_DR_CANNOT_CREATE_VERTEX_BUFFER |
The vertex buffer could not be created. |
IS_DR_DEVICE_OUT_OF_MEMORY |
Not enough graphics memory available. |
IS_DR_LIBRARY_NOT_FOUND |
The DirectRenderer library could not be found. |
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_CAMERA_HANDLE |
Invalid camera handle |
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_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_SUCCESS |
General error message |
IS_NOT_CALIBRATED |
The camera does not contain any calibration data. |
IS_NOT_SUPPORTED |
The camera model used here does not support this function or setting. |
IS_NULL_POINTER |
Invalid array |
IS_OUT_OF_MEMORY |
No memory could be allocated. |
IS_SEQUENCE_BUF_ALREADY_LOCKED |
The memory could not be locked. The pointer to the buffer is invalid. |
IS_SUCCESS |
Function executed successfully |
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. |
