CAMBRIDGE, UK The Ambarella A5s family of SoCs combines high-speed CPU and low-power 45nm technology to support megapixel photography in pocket-sized hybrid cameras.
The A5s system-on-a-chip delivers full high-definition (HD) recording, 14 megapixels of still photography, and the ability to capture HD and internet video simultaneously.
A 533-MHz ARM11 CPU and enhanced graphic capabilities enable a new class of lifestyle cameras with features such as a smart-touch screen, intuitive graphic user interface, 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, says 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 US $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 10 MP still pictures as well as generate and compress high-definition video in both 720p60 and 1080p30 formats.
The A5s30 enables burst recording of 8 MP still images at 30 frames per second with appropriate sensors. The A5s50 supports the standard interlaced HD broadcast format 1080i60 optimized for display on TV.
