New research suggests that tangible cameras can make meake of sharp shots

No expert photographer feels to know that the camera stable, sharp shot. According to new research led by Brown University Engineers, traditional wisdom is not always correct.

Researchers showed that with the help of smart algorithm, the camera in motion could produce high resolution images than the camera fully kept. New image processing techniques run -off the mill camera can enable fast imaging for scientific or archive photography, along with photos of the mill camera hardware.

“We all know that when you shake the camera, you find a picture of fading,” said Pedro Felzins Wall, a professor of engineering and computer science in Brown. “But what we show is that a picture caught by the walking camera actually contains additional information that we can use to enhance the image solution.”

This study was recently presented and posted at the International Conference on Competition Photography Archeo Print print server.

Digital cameras produce images by creating an average of light intensity on a row of pixels. This leads to a resolution limit: small details from the same pixel slip into the pixel rather than to recover inside it. Because of this, the details of the sub -pixel are blurred.

The Felzins Walb and his team use a camera motion to produce the techniques prepared by the pixel resolution. When the camera runs, the small points of light are the leaves that cross more than one pixel. The team’s algorithm uses these tracks as additional information, exactly to indicate where there should be good details, they should be constructed on a fine grid. The result is a super -resolution image in which the original pixel array is faster in detail.

For the study, researchers tested the traditional camera on the stage and tested the technique, which enabled them to test their techniques in various movement scenes. In some cases, the team drew several photos by moving the camera a bit between the exhibitions, then used its algorithm to build the same image from a number of shots caught by the camera between the camera. In other cases, the team moved the camera during each exhibition and restruited a high resolution image from the same moving shot.

In both cases, the team showed that their algorithm camera could use the motion so that images could be created with more resolution.

“There were some ideological things that were suggested before,” said Felzins Walb. “But we show that there were some assumptions in these previous ideas that were not true. And therefore it is proof of the idea that we can really recover more information using the movement.”

Researchers imagine enough potential applications for their techniques. Researchers say a dynamic phase setup used for experiments can be used for art works or sample super resolution archive photography. This technique can also be useful for photography from planes.

The team also sees the possibility of an algorithm for a day on commercially available cameras.

“There are existing systems that camera use to fade,” said Felzins Walb. “But no one has actually tried to use it to increase the resolution. We show that this is the work you can do.”

The team plans to continue their technique development and find industry partners available to the public in the coming years.
