Your Smartphone Photos Could Be Soon Noise-Free

The smaller the sensor, the worse the image? A new technology may soon ensure that sensors get a lot more light. The result: The nasty noise belongs to the past.
Noise is created by digital photography including (the reasons are varied) if too little light with the camera sensor comes along, trying about the software “patch” missing image information in dark areas of the image. You shoot in automatic mode, the software adjusts the ISO sensitivity high. As a result, The noise becomes stronger.
Why is it that gets too little light on the chip? Apart from the pure size is among the usual filters. You can pass only the light of a certain wavelength. Accordingly, the sensor can understand whether to render the pixel in blue, green or red. The downside: Because they are the light-sensitive sensor, about two-thirds of the possible brightness “swallowed”.

Rajesh Menon of the University of Utah scientists have now introduced a revolutionary concept, which allows each individual photon. Full light output, so. How did they get that? The researchers have developed a kind of transparent filter. More precisely: a few micrometers thin plastic with varying elevations. Depending on is broken as the light according to wavelength, it creates an intensity pattern on the sensor. It takes only an algorithm that converts this pattern in image information.

NASA Is Shooting Asteroids So
With a regular digital camera can you down then so be the ISO sensitivity and less noisy photos. But the researchers stated that is the compatible with mass production system for cameras can be used with very small pixels – so also in smartphones. In three years, the technology should be then ready for series production. Just smartphones can score points but in good light conditions, have problems with noisy recordings at dusk or at night but also after years of improvements in the area of the camera.
That sounds quite realistic, because NASA is one of the sponsors of the research project. So the new system should be used also to photograph near-Earth objects in outer space. In addition, Menon has founded the company of Lumos imaging and is in talks with several camera manufacturers and IT companies.
It seems as if we finally Smartphone photography can be glad in three years to a new level which seems currently to stagnate. Apart from minimal improvements to the luminous efficiency and increases the resolution, the cameras are all at similar high level in current top models.
