How to convert image from usb camera to array

[Chauhan]

Hello Everyone

I am trying to use a USB camera and then convert the image obtained to array format so that i can have access to each pixel intensity. But when i am using IMAQ image to array, it gives error like invalid image format.  Thought i an see the image in image window it is just that i can not convert it to array. A little help from anyone is appreciated. 

Regards

You are using a USB camera, which generates color images.  You are using ImageToArray for grayscale images, which is why the image format is not compatible.  You need to do one of two things:

1.  Convert your color image to a grayscale image.  IMAQ Cast is the easiest way to do this - just create a second image that is grayscale and use it as the destination.

2.  Use ImageToArray for color images to extract the data you need.

IMAQ cast did the work.
