A12A75 Advanced HD Automotive Camera SoC
The A12A75 SoC family enables single-channel Quad HD (4MP, 1440p) at 30fps, Full 1080p HD at up to 60 fps, and dual-channel Quad HD, providing support for video recording through the front windshield as well as through the rear window or inside the vehicle.
The A12A75 combination of advanced image processing, High Dynamic Range (HDR), 3D noise filtering, smart auto-exposure, and full-resolution oversampling provides superior image quality, allowing the capture of license plates and other key details, even in low light conditions. The increased resolution allows a wider field of view to be captured, while still maintaining a high level of detail throughout the image.
The A12A75 SoC includes a high-speed 792-MHz ARM? Cortex?-A9 CPU with Neon DSP extensions to support advanced analytics algorithms including Lane Departure and Forward Collision Warning Systems.
A12A enables WiFi connectivity for reviewing the captured video clips on iOS and Android devices as well as an interface to 4G/LTE modems for remote viewing or cloud storage of the video. The SDK leverages Ambarella’s multi-stream encoding capability for Full HD video recording while simultaneously sending a second stream to the smartphone.
