Hello!
I was wondering if anyone here has previously worked with ArduCam. My group and I are making progress on our project but were wondering if anyone else could help us with a small issue. We are making an attendance face recognition system and were planning on using an Arduino (with OV2640) to capture the image. We were wondering if there's anyway to have the Arduino take an image when the code is complied so that we wouldn't have to use the host app.
You might get more help if you edit the thread title to say that you want help with Arducam.
The problem with this - and most queries regarding the "Arducam", is that the Arduino (most of the simple and less expensive ones) have no capability for image processing, let alone video.
You are therefore better off connecting the camera directly to the image processor, such as a Raspberry Pi. I don't know if an "Arducam" is easily interfaced to a Pi, so it may not be the best of camera choices.
This is an example of the "Arduino to do anything" meme. 
You can use the Arduino for control but for the video you need a DSP (Digital Signal Processor) or something in that class to do the video and audio. Check into what has to happen to process your signals. It will require a huge amount of math and array processing to do it in something less then a few days. Check how much data in bytes you will have to process. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!

Do you need a sort of image buffer? Or a way to temporary store the captured image?
Not sure I understand.
