Arduino Digital Camera Video Feed

Is it possible to get video feed from a digital camera using an arduino and display it in a computer over the serial?

At a frame rate of about one frame per day, yes.

Tich, tich. A little arithmetic, please. Let's assume a colour VGA camera. 640 (horizontal) x 480 (vertical) x 3 (red, green, blue) pixels at one byte per pixel = 921 600 bytes.

Let's say 115 200 baud, or 11 520 bytes per second = 80 seconds for one image.

Now, we need to discuss how we get that image into the Arduino in the first place.

Maybe you can do a little JPEG before the image gets to the Arduino.
