Imaging technique captures better night scenes

Japanese image processing software vendor Morpho (Tokyo, Japan) has developed a technique that enables a camera to simultaneously capture both the portrait of, and a night scene behind, a subject simultaneously.

Capturing a portrait in a night scene requires a flash to be fired to light up the subject. However, this usually means that the background tends to end up dark as the shutter speed is too fast to collect enough ambient light.

Morpho's so-called "Night Portrait" technique overcomes that problem in a similar way to slow-synch flash in which with-flash and without flash images are merged.

The technique uses Morpho's motion detection technique called Softgyro so that users can capture a blur-free night portrait without a tripod.
