Converting a snapped image from usb webcam to rgb model color

Question

Hellow everyone,
I am trying to convert  a snapped image using usb webcam to RGB model. I have two VIs, for snapping and the other for converting JPEG to RGB as the attached VIs bellow. My problem is how to connect these two VIs in one VI to make direct conversion from snapping to RGB model. I am using LABVIEW 8.6

So the two VIs that you have are not directly compatible with each other. Notice that the first one uses IMAQ VIs (an add-on), while the second is using VIs from NI's Base Package. This means that the first VI (the snap) outputs an "Image" type, while the second VI is using an "imagedata" type.
To clarify, you want the histogram of each color in the image, is that right? This is what a histogram is:

If so, you can use the IMAQ ExtractColorPlanes VI to extract each individual color plane...

...and then you can use the IMAQ Histogram VI to map the histogram of that color plane.
