IMAQ Set User LUT VI

NI-IMAQ VI

IMAQ Set User LUT VI

Installed With: NI Vision Acquisition Software

Downloads a custom lookup table (LUT) to an image acquisition device. This VI can download 8-bit or 16-bit LUTs for analog or digital devices. If the image acquisition device has multiple LUTs, you can input all of the LUTs into this VI. Call this VI before starting the acquisition.

Note  This VI is not applicable for the NI PCI-1405, NI PCI-1426, NI PCIe-1427, NI PCIe-1429, NI PCIe-1430 or NI 17xx smart cameras.

IMAQ Session In identifies the device.

Tap 0 LUT (Red) is used for analog monochrome devices, the red channel for RGB digital cameras, or tap 0 on digital devices.

If the bit depth is 8-bit, wire an array of 8-bit unsigned integers containing 256 elements. If the bit depth is greater than 8-bits, wire an array of 16-bit unsigned integers containing 2n elements where n is the bit depth of the camera (1,024 for 10-bit, 4,096 for 12-bit, and so on).

Tap 1 LUT (Green) is used for the green channel for RGB digital cameras or tap 1 on digital devices.

If the bit depth is 8-bit, wire an array of 8-bit unsigned integers containing 256 elements. If the bit depth is greater than 8-bits, wire an array of 16-bit unsigned integers containing 2n elements where n is the bit depth of the camera (1,024 for 10-bit, 4,096 for 12-bit, and so on).

error in (no error) describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

code code is the number identifying an error or warning. If status is TRUE, code is a non-zero error code. If status is FALSE, code can be zero or a warning code. Use the error handler VIs to look up the meaning of this code and to display the corresponding error message.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Tap 2 LUT (Blue) is used for the blue channel for RGB digital cameras or tap 2 on digital devices.

If the bit depth is 8-bit, wire an array of 8-bit unsigned integers containing 256 elements. If the bit depth is greater than 8-bits, wire an array of 16-bit unsigned integers containing 2n elements where n is the bit depth of the camera (1,024 for 10-bit, 4,096 for 12-bit, and so on).

Tap 3 LUT is used for tap 3 on digital devices.

If the bit depth is 8-bit, wire an array of 8-bit unsigned integers containing 256 elements. If the bit depth is greater than 8-bits, wire an array of 16-bit unsigned integers containing 2n elements where n is the bit depth of the camera (1,024 for 10-bit, 4,096 for 12-bit, and so on).

IMAQ Session Out has the same value as IMAQ Session In.

ierrcodeclst.gif

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
