Night Sight in the pixel phones

Have already been two years since the launch of the first smartphone of Google, pixel, which radically elevated the level of image quality that we could expect from mobile cameras.

Google continues to expand its leadership with the introduction of a new, equally revolutionary camera. It’s called Night Sight and allows your phone’s camera to see in the dark. It just doesn’t require any hardware or additional cost: Night Sight is a new camera mode for Pixel phones.

Google is offering all Pixel models to maintain that high quality while providing an easier way to access the mode. The night view is transcendental because it is a software change that offers a jump in performance that previously could only bring a new hardware.

Night Sight it’s not just a prolonged exposure mode for your phone. In the past, you would have needed a tripod to stabilize your camera to get information about the light for several seconds and so get a brighter picture on the night than the human eye can see. You are now achieving similar results with a handheld Pixel by segmenting the exposure into a burst of consecutively taken frames, which are then reassembled into a single image using the company’s algorithmic magic.

Before taking a picture, Google’s Night Sight camera makes a ton of multi-factorial calculations. Using what the company calls motion measurement, the Pixel takes into account its own movement (or its absence), the movement of objects in the scene and the amount of light available to decide how many exposures to take and how long they should last.

Night Sight Photos will take up to six seconds and up to 15 frames to capture an image. Google has set a limit of one second per exposure if the phone is perfectly still, or a third of a second if it is a handheld. At the technical level, the software is analyzing how the Chrominance registry histogram of each photo changes with different shades. Google calls this method Fast Fourier Color Constancy (FFCC).
