With almost 5 million views on YouTube, video of the Ultimate Smartphone Photobooth is quickly spreading the word about the Qualcomm® Snapdragon™ 540-degree photobooth made entirely of 130 HTC One smartphones powered by  Snapdragon processors. Wondering how the Snapdragon Booth makes images like these possible and how you can be a part of the action? We’ve got some behind-the-scenes details right here.

How does it work?

Qualcomm Technologies developed software that runs on each of the 130 HTC One smartphones and each smartphone connects via WiFi to a server. From the server we send commands to all the connected smartphones, including focus, zoom in, and capture. The operator cues a countdown clock which is displayed on a tablet within the rig. This signals the time for the participant to strike a pose. When the clock hits zero, 130 smartphones function essentially as one camera, and capture an average of about 60 frames per second on each smartphone.

Each image gets a time stamp and our server selects one synchronized image from every smartphone and downloads them. Once downloaded, another image server checks to see if every image is properly aligned then combines them into an animated sequence. From there, a GIF file is exported for display.

What is the difference between the rig in the video and the rig at live events?

For the video, sequences were created from footage captured by Snapdragon powered HTC One phones and then footage was compiled and exported to create a final video using editing tools such as Final Cut Pro.

The live event rig creates footage captured through the HTC One phones. From there the footage is sent to a server to align the footage and convert it in to a GIF.

Why 130 HTC One smartphones?

The HTC One is powered by a Qualcomm Snapdragon processor, designed to provide leading camera functionality, photo burst capabilities and cutting-edge software that is used in order to execute the rig. By working closely with HTC’s marketing and development teams and utilizing Snapdragon powered devices, the team was able to make this rig a functional reality.

Is this all done by Snapdragon processors?

The video version features footage from the Snapdragon Booth captured entirely by Snapdragon powered cameras, which were controlled via closed network by a Snapdragon-powered device. The live rig creates GIF files, which are similarly captured and controlled by Snapdragon-powered devices. The live rig’s GIFs are automatically collated and rendered by an image server.

If my photo was taken in the rig, where can I find it?
