GoPro Hero 4 said to support 4k/30fps, 1080p/120fps, HDR and maybe 3D

The GoPro HD Hero 4 will be powered by the Ambarella A9 camera SoC, which, besides being able to film in 4K resolution at 30fps, will be able to record in ultra high framerate modes for HD and fullHD, namely 1080p at 120fps, and 720p at 240fps.

Also included in the A9 specifications is 700Mpixels/s oversampling performance, multi-exposure HDR and WDR tone mapping, and electronic image stabilization EIS. There’s also WiFi capabilities with remote viewfinder and playback functions.

On the more speculative side, there are rumors floating around that the Hero 4 will sport two lenses side-by-side for filming in 3D, but that has not been confirmed

Major camera makers have a tough time due to smartphones

Most of the big camera makers are scaling back production as camera sales drop dramatically. Nikon forecasts 2013 sales to be down 23% over 2012. The culprit is said to be the smartphone, whose cameras are getting better.

For those new to 3D, the interaxial distance is the spacing between the center of the left camera lens and the right camera lens. The interaxial is a critical component to creating good 3D depth effects. Too large, and the viewers eyes will hurt. Too small, the depth effect will be minimal. The key is to select the right lens spacing for the “depth box” in front of the camera. Objects within the depth box will have appropriate parallax and good depth effects.

Most consumer and semi-pro 3D cameras have relatively narrow lens spacing – they are perhaps best for shooting 3D photos or video of kids in the backyard or at the park. Beyond a few tens of feet (or meters) the depth effect vanishes and those parts of the image appear flat.
