We don’t have the habit of obsessively covering every rumor and leak out there, but this one caught our attention. We knew the Nexus 5 was near at the end of August, when Google decided to decrease the price of the already affordable LG Nexus 4 by $100. Now, as we’re nearing the end of October, when Nexus 5 is said to be launched, more interesting rumors and leaks have started to appear.
A Nexus 5 log obtained by Myce.com and Androidworld.it shows interesting details about Nexus 5’s camera. Google’s upcoming smartphone, if we are to believe to the diggings, will be the first one with a MEMS camera. And it seems that the MEMS camera has some truly innovative features. First of all, its strongest point is that it can focus 7 times faster than current cameras. Also, it can take burst images very fast and if the object you’re trying to take pictures of isn’t moving very fast, then you’ll be able to focus later, a feature which seems to be borrow from Lytro cameras. Victor from PhoneArena explains better what the MEMS technology is all about:
MEMS is the same technology that brought us microphone, gyros and barometers in a tiny smartphone. Auto-focusing in VCMs happens when a current is sent through a coil causing the moving elements of a camera to move in the direction of a magnet. There are a few set steps for the moving elements and at each one the camera evaluates the focus to determine whether the image is in focus or not (if not it just moves one step further and re-evaluates).
MEMS technology on the other hand can focus nearly 7 times faster and is much smaller. It uses electrostatic force to draw to solid-state comb-shaped surfaces together, but they never touch and degradation takes much longer. Instead of having multiple moving elements you only have one with extremely quick auto-focus and power consumption of 1mW, hundreds of times less than VCM modules.
The MEMS camera will have a super-fast auto focus that will lock in only a fraction of a second, no matter if its day or night outside. If this turns out to be true, then Google will bring this technology to the mainstream and will join the battle with other smartphones that are very good in the camera field. The iPhone 5s, for example, comes with the ability to record slow motion videos, which is a feature that many users out there have already fallen in love with.
Besides the revolutionary MEMS technology, here are other possible details about Nexus 5’s camera: 8-megapixel sensor that is not backside illuminated, f/2.4 aperture, sensor size of 1/3.2 inch. In the video below you will find a demonstration of the MEMS camera at the MWC 2013 from Barcelona.
