Ambarella has released the A5s family of SoCs that combines high-speed CPU and low-power 45nm technology to support megapixel photography in pocket-sized hybrid cameras.

The A5s SoC delivers full high-definition (HD) recording, 14MPixel of still photography, and the ability to capture HD and Internet video simultaneously.

A 533MHz ARM11 CPU and enhanced graphic capabilities enable a new class of lifestyle cameras with features such as a smart touchscreen, intuitive GUI and wireless networking.

The low-power design combined with Ambarella's unique image sensor processing and H.264 compression technology assures long battery life and high-quality, HD capture of everyday activities.

Sophisticated spatio-temporal filters reduce noise without causing blur to deliver clearer images, especially noticeable in low-light indoor scenes.

For high-contrast and outdoor scenes, the chip's automatic local exposure correction adjusts each pixel to highlight sharp details from areas that otherwise would be over- or underexposed.

By incorporating a flexible, low-power processor with megapixel photography, HD and Internet video capture, said Fermi Wang, Ambarella CEO, the A5s enables a true mass-market camera.

Ambarella expects that full HD consumer hybrid cameras based on the A5s platform will be priced at or under the critical $149 end-user price threshold in 2010. The A5s family consists of three products: A5s25, A5s30 and A5s50. Each is available with a full reference design.

The A5s25 integrated circuit can capture 10MPixel still pictures as well as generate and compress high-definition video in both 720p60 and 1080p30 formats.

The A5s30 enables burst recording of 8MPixel still images at 30fps with appropriate sensors. The A5s50 supports the standard interlaced HD broadcast format 1080i60 optimized for display on TV.
