IMAQ MulDiv VI
Owning Palette: OperatorsInstalled With: NI Vision Development ModuleComputes a ratio between two images. Each pixel in Image Src A is multiplied by the integer value specified in the input Constant before being divided by the equivalent pixel found in Image Src B. To avoid losing information, a temporary variable giving higher definition is used to perform the operation. If the background is lighter than the image, this function can correct the background. In a background correction image, Image Src A is the acquired image, and Image Src B is the light background.

Constant is the value multiplied by each pixel in Image Src A before each pixel in Image Src A is divided by the equivalent pixel in Image Src B. |

 |
Image Src A is a reference to the first source image. |
||||||
|
Image Dst is a reference to the destination image. |
||||||
|
Image Src B is the reference to the second source image. |

error in (no error) describes the error status 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.

Image Dst Out is the reference to the destination (output) image that receives the processing results of the VI. If the Image Dst is connected, Image Dst Out is the same as Image Dst. Otherwise, Image Dst Out refers to the image referenced by Image Src A. |

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.
