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, Ambarella’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, the A5s enables a true mass-market camera,” said Fermi Wang, Ambarella CEO. “It fits the mobile consumer lifestyle, is fun to use, and leverages Ambarella’s strategy to bring rapid innovation and top-notch image quality to an increasingly demanding market.”.
Targeting the expanding market of pocket-sized lifestyle cameras, the A5s platform represents an industry breakthrough in value and functionality for high-quality still and full HD video performance. 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.
