Researchers acuminate photographs by capturing assorted low-quality images

Technology.am (Oct. 2, 2009) — The MIT Graphics Group is assuming that combing several low-quality exposures with altered focal base can crop a bluff photo than a single, higher-quality exposure.

stayfocusedrHasinoff, MIT advisers Fredo Durand and William Freeman, and Kiriakos Kutulakos of the University of Toronto devised a algebraic archetypal that determines how abounding exposures will crop the sharpest angel accustomed a time limit, a focal distance, and a light-meter reading.

Hasinoff says that abstracts in the lab, area the cardinal and continuance of digital-camera exposures were controlled by laptop, bore out the model’s predictions.

A agenda camera could calmly abundance a table that specifies the ideal cardinal of exposures for any set of circumstances, Hasinoff says, and the camera could accept a audible operational ambience that invokes the table.

The multiple-exposure approach, he says, offers accurate advantages in low ablaze or back the arena covers a ample ambit of distances.

Today’s fastest customer cameras can abduction about 60 images in a second, Hasinoff says. If the MIT researchers’ archetypal bent that, beneath assertive conditions, the ideal cardinal of exposures in a tenth of a additional would be eight, the fastest cameras could administer alone six. “But there’s still a big accretion to be had,” Hasinoff says.
