I'm using a Raspberry pi to monitor a self-service fridge. When the door opens, a shell script is being executed to capture pictures until the door closes again.The problem, however, is the speed of the ARM-processor. Capturing in full resolution using fswebcam takes 2-4 seconds, which is too long.Our idea to solve this is to split the process:Capture raw images and save to memory cardAfter the door is closed, process the raw data. This is not time-critical.Now, my questions are:Is this possible / wise?Which program should I use?
Capture raw image from V4L (webcam) device
