GoPro Hero 3
For adrenaline junkies across the world the GoPro Hero3 is the action cam of choice, but we could soon see them hankering after the GoPro Hero4.
GoPro's chip supplier has just released its new model, giving us a taste of what's to come in the Hero4. And while the GoPro Hero3 isn't exactly old, and is certainly no slouch, the specs of the new chip show welcome upgrades all round.
The chip at the heart of the Hero3 is made by Ambarella, and its new A9 4K Ultra HD Camera SoC is likely to be the brains inside the Hero4.
To recap, the current top-level Hero3 Black Edition will do 4K but up to a maximum of 15 frames per second (fps), 1080p at 60fps and 720p at 120fps with 12MP stills.
The new chip, destined for "mirrorless, sports, and digital still cameras" has a 4K Ultra HD H.264 encoder, shoots 1080p at 120fps and 720p at 240fps, 700MP overmulti-exposure HDR, Wi-Fi and electronic image stabilisation. That's a doubling of frame rates, plus a lot of incremental improvements that should make the GoPro Hero4's performance even closer to professional camcorders.
The Ambaralla chip will also cope with a maximum 32MP resolution, though it's unlikely that the GoPro 4 would sport a sensor with such a high pixel count.
There's no word from GoPro about a Hero4 yet, but we're hoping it turns up in time for a spot of summer adventuring.
