IMAQ Histogram doesn't work

[Pavel_47]

Hello,

In the example that follows the IMAQ Histogram block doesn't do its job: all statistics are 0.

Where I've been mistaken ?

Thanks in advance.

Well, look at the wire connected to the input of the Histogram Function -- it comes from an IMAQ Create function that creates a blank image!  So you get the Expected Answer, every intensity is zero.  Fix your wiring.

Resolved.

The problem was the IMAQ Histogram doesn't work with RGB (I used PC web camera).

Workarounf: insert the Customizing function (that transforms 32-bit RGB to 16-bit grey) between ROI image and Histogram.
