Aptina has announced what it says is an intelligent imaging SoC aimed at backup camera solutions. The ASX344AT features built-in image processing and claims to deliver 180 degree viewing with robust de-warp functionality.

The National Highway Traffic Safety Administration (NHTSA) found that 180 degree camera solutions, such as the camera solutions using the ASX344AT, provide a nearly 60 per cent improvement over traditional mirror-based systems and a nearly 15 per cent improvement over traditional 130 degree viewing systems for backup accident avoidance.

The ASX344AT SoC was designed specifically to lower cost and enhance time-to-market. Combining a high-performance sensor, image processing, and 180 degree de-warp capabilities, the ASX344AT is a single-chip solution for backup camera solutions. This dramatically reduces overall system cost as well as physical solution footprint. The SoC comes with a comprehensive software toolkit that simplifies creation of multiple perspective views for lens distortion correction and improves time-to-market for manufacturers, Aptina noted.

The ASX344AT is in a 1/4in optical format with VGA resolution. The sensor uses a large 5.6um pixel that provides amazing low-light and high dynamic range, giving an accurate image in challenging lighting conditions, stated the company. The SoC processing capabilities include sophisticated functions such as colour recovery and correction, auto white balance, gamma, sharpening, lens shading correction, on-the-fly defect correction and auto exposure.

The SoC includes four overlays that may be blended simultaneously, with a choice of 32 colours selectable from 64,000 total. The Universal Asynchronous Receiver/Transmitter (UART) interface enables manufactures to customise viewing modes that can adjust dynamically based on driver situation. The SoC offers NTSC/PAL output for universal communication with regional displays.

The ASX344AT meets the stringent AEC-Q100 qualification with operating temperatures of -40°C to 105°C and is in mass production.
