Product Brief
Overview
The Ambarella A12W Wearable Camera Processor is a
system-on-chip solution that integrates an advanced image
sensor pipeline (ISP), an H.264 encoder, and a powerful ARM®
Cortex™-A9 CPU for advanced analytics and user applications.
Targeting social and professional wearable camera designs,
the A12W is fabricated at the 28 nm manufacturing process
and is delivered with an SDK that is optimized for low power.
Additionally, the A12W processor family enables powerful image
processing tools such as lens distortion correction, high dynamic
range and motion compensated filtering and sharpening.
