Sony details part 1: Camera

In the run up to Mobile World Congress we first mentioned what later became our headline campaign, #XperiaDetails. We wanted to show you how seemingly subtle changes can make a big difference, everyday and as part of that we’re running a series of posts here on the blog to show you just how those differences add up.

Hiroshi:

We look at smart phone photography on three levels – first, the everyday snapshots, we call these “Life Logging” (not to be confused with our Lifelogging app). Above that, we have what we call “Memory” photographs, these are those shots where you want to go beyond just recording what happened and you want to record a bit of how it felt to be there. Finally we have “Art” photos, where the main aim creating art. With Xperia Z1 we created a smartphone that could easily master the first two, and with Xperia Z2 we’ve created a smartphone that takes this high level of capability and applies it to videos as well.

There are three key ways we do that. Using 4k video we remove the need to constantly pan around to catch the action when filming important moments, simply hold the camera stock still and pinch to zoom / track the key moments during playback, the 4k resolution means that you can zoom right in and still have pin-sharp video that looks great both on the phone screen and on a TV. We have also created a new version of Steadyshot. As resolution and sharpness get better and better, image stability becomes more and more of an issue, and when people remember great moments in their life I can guarantee they don’t remember an image that shakes around. To get rid of this we zoom in slightly using Xperia Z2′s large sensor to provide a buffer around the edge of what is being recorded. We then use the accelerometer to work out if the phone is shaking, this allows the software to compensate by using the free areas of the sensor. This is a technical way of saying you end up with shake-free video that looks how you remember it.

Finally, we created Timeshift video. Some moments are over too quickly for a video to really capture how they felt. Pull off a difficult snowboarding trick and despite how incredible it felt to do it, the video shows you in the air for less than a second. Timeshift video is designed to change this. In Timeshift video mode we kick the Xperia Z2′s video camera into overdrive, grabbing images at rate of 120 per second and by doing this we allow the software to dramatically slow down the video without sacrificing quality. The result is pin-sharp, dramatic slowmotion for moments that deserve to live for longer.

Everything Sony mobile does is about experiences and the video capability of Xperia Z2 is an important part of that story. By improving this aspect of our technology we allow people to capture video that helps them to re-live important parts of their life, and in doing so we have created a smartphone that becomes an even more vital companion for its users. Like you said at the beginning, details matter.
