The nascent market for 360-degree cameras is getting more crowded. Meet Giroptic, which joins the likes of Bublcam, Centr Cam and Panono in building hardware to capture a more fuller picture of what’s going on around you.

Giroptic is currently running a Kickstarter campaign to raise money to put its prototype egg-shaped 360-degree camera into production and has smashed past its original goal of $150,000 — with more than $610,000 raised at the time of this writing and still a full 36 days left on its campaign.

How does Giroptic differ from rival 360-degree cameras? It’s offering 360 HD video (1080p “equivalent image quality”) — including real-time streaming — which sets it apart from Panono, which only does photos at present.

Giroptic also stitches the images it captures together inside the device itself to make a real-time panorama.

The actual captured portion is 150 degrees from top to bottom out of a possible 180-degrees, so it’s not getting everything — typically there’s a blind spot beneath the device, as if a football had had its base sliced off.

This is because Giroptic has three 185-degree fish-eye lenses mounted near the top. Bublcam bests this viewing field with a true spherical 360-degree view (with zero blind spots), thanks to four 190-degree lenses, but it does not do the stitching on the device itself.

And then Centr Cam takes a smaller slice still — offering a 56-degree vertical field of view vs 150 degrees on Giroptic –so it’s capturing a lot less.
