  @Prynok Do you have a still image from the camera. I was able to do a get from an image from the camera without a problem. Just sample code below

  
  function setup()
      cameraSource(CAMERA_BACK)
  end
  
  
  function draw()    -- This sets a dark background color 
      background(40, 40, 50)  
      img=image(CAMERA)
      if xx~=nil then
          sprite(xx,WIDTH/2,HEIGHT/2)
      elseif img~=nil then
          sprite(img,WIDTH/2,HEIGHT/2)
      end
  end
  
  function touched(t)
      if t.state==BEGAN then
          xx=img
          r,g,b=xx:get(200,200)
          print(r,g,b)
      end
  end

  @dave1707 Thanks, I got it working, your way is probably easier though!

  CAMERA is simply the string "CAMERA." You needed to use image(CAMERA):get(...)

  While @SkyTheCoder's method works, it's slower since you need to rasterize the image every time you want to get a pixel. He probably knows that, though. That was just for demonstration purposes.
