如何从相机获取当前帧作为图像？

Question

Hello im trying to make my own special custom code scanner. My app's render a special custom barcode and I need to make a very simple scanner that will take whats currently being seen with the camera and quickly process it to decode the barcode. So how can I grab the frames from the camera and use them as images without pressing the "take" button.
