Ambarella, the company that makes the image processor SOC (system on Chip) for GoPro have just released their up coming camera SOC specs – the A9. Considering that Ambarella have been exclusively making the imaging SOC for GoPro, it is not unreasonable to assume that this new SOC outlines the features of the Next GoPro.
Here is how the A9 is described:
The Ambarella A9 Camera SOC enables development of the next generation of HD and Ultra-HD video cameras with leading-edge video features and exceptional still-image quality.
In addition to 4K Ultra HD video resolution at 30 frames per second, the A9 supports high frame-rate video for capturing fast-action sports with 1080p video at 120 frames per second or 720p video at 240 frames per second.
The A9 includes dual-core ARM® Cortex™-A9 CPUs providing the performance required for advanced applications including wireless connectivity to smartphones for video-streaming or image sharing.
Looking at the spec sheet, this new SOC will include quite an interesting set of features.
Mainly, is seems that GoPro 4 will have 4K encoded using H.264 and be capable of 120p @1080, as well as have integrated Wifi and Social media sharing capabilities.
Of course, GoPro may opt to make several flavors of that SOC enabling and disabling features to segment the market into a High/Medium/Low price tags as they did with the GoPro 3+ and the colored editions.
