A team of researchers creates a One-cubic-millimeter disposable camera. the resolution is 250 x 250px.
This tiny camera will be increased its quality and resolution in the future for sure. But what I'm thinking is if I have 300 of this little pin-hole, I would group them together and take a picture with these tiny camera. Then stitch all the images, and I would have 250 x 250 x 300 resolution images (equivalent to 18 megapix). Imagining that the final result will be a very interesting fry-eye-like image.
