In the age of miniaturization, its kind of difficult to keep up with the smallest electronic gadgets that are multiplying by the dozen. Here we take a look at some of the smallest functional cameras in the world to see if we can actually settle the debate of which one is the smallest of them all.

Hammacher Schlemmer sells a miniature camera measuring 1.125 inches long, 1 inch wide and 1.062 inches deep. It can easily rest on one finger.It has a built in battery that can be recharged after its 30 minute usage time. Plus a USB port that can be used to transfer the images it takes. Its 1.195 cubic inches volume is certainly small.

JTT’s Chobi Cam One is another competitor for the position of the world’s smallest camera and while its dimensions are not as compact, its 0.934 cubic inches volume certainly is. However it has an external battery and that does take up more in size.

Swiss company CSEM has its Vision-In-Package or VIP optical sensor which sits in a package containing its own processor, and is smaller than the size of a stock cube. Unfortunately this little baby that uses Bluetooth to transfer data is not currently commercially available. However future science projects for robotic surgery and drones sound promising when using the VIP.
