The multitude of lenses that make up an insect's eye is providing inspiration for a new generation of super-slim camera phone.
Conventional camera lenses cannot be shrunk below a few millimetres in thickness before reducing the field of view. But a compound lens, made from hundreds of tiny "micro lenses", can be made around one-tenth of the width, while retaining the same field of view and quality of image.

That sounds promising.

The image quality of such a small compound lens would be limited to about 250 by 250 pixels, or 0.06 of a megapixel. The lenses should be relatively cheap and simple to manufacture, as micro lenses can be made using existing lithographic techniques, Bräuer adds.
Camera phones have exceeded that small range.

"Camera phones have exceeded that small range."
Nah man.. it's 250x250 for each small compound lens. So, when constructed into a 10x10 matrix of lens, you get approximately 6Mpix of resolution. |

so in theory you incorporate this technology into digital cameras, not phones, you could have say a 100x100 compound lens matrix. which would produce upwards of a 50 megapixel photo. now take 3 100x100 compund lenses, each one picking up the 3 different colours red blue and green and thats how you can create super high quality 50 megapixel photo.

Yeah but if thats true, there must be a catch, because they werent eager to put it in regular cameras, only camera phones, and compactness is almost as important in digicams.

The technology is in its infancy so lets see what becomes of it over time.to early to speculate,but the idea looks promising.

sooner or later camera phones in installed with a human eye for the best picture quality possible...

i like the idea but its impossible
you would first have to work out how to read the signal sent from the retina...then decipher those signals...then process them....then create the image

yes i have 
i am an optical physicist and berkely
i have also worked out the string theory, the big bang theory and have found out how to cut a hole in the space time continuem in order to travel mass distances within seconds.....because im also an astro physicist at berkely and NASA at the same time

excellent davo
all i know about the near future of camera lenses is.. where they will use water as the lense.. somthing to do with the eyes aswell..

yeah because water has a little bit of surface tension it .....wait ill have to draw it...its too hard to explain.
it would mainly be used to help with focusing and object like this.
