  Here's an example. Use collectgarbage() to prevent Codea from crashing when it updates img.

  displayMode(FULLSCREEN)
  
  function setup()
  end
  
  function draw()
      background(40, 40, 50)
      img=image(CAMERA)
      collectgarbage()
      if img~=nil then
          sprite(img,WIDTH/2,HEIGHT/2)
      end
  end

  Why that doesn't work???

  
  function setup()
  
  end
  
  function draw()
      i = image(CAMERA)
      collectgarbage()
      imgCopy = i:copy(i.width/2, i.height/2, 500, 500)
  end

  Are you after something like this. Tap the screen to copy a section of the Camera image.

  displayMode(FULLSCREEN)
  
  function setup()
  end
  
  function draw()
      background(0)
      i = image(CAMERA)
      collectgarbage()
      if imgCopy~=nil then
          sprite(imgCopy,WIDTH/2,HEIGHT/2)
      elseif i~=nil then
          sprite(i,WIDTH/2,HEIGHT/2)
      end
  end
  
  function touched(t)
      if t.state==BEGAN then
          print(i)
          imgCopy = i:copy(i.width/2, i.height/2, 500, 500)
      end
  end
