Alpsentek "hybrid" vision sensor for HDR imaging

From the VISION 2022 exhibition in Stuttgart:

AlpsenTek® launches the ALPIX-Eiger™, a fusion vision sensor for high-end imaging 

AlpsenTek®, a leading developer of fusion vision sensors, announced the launch of the ALPIX-Eiger™ fusion vision sensor chip, specifically designed for high-end imaging applications. Using the original patented Hybrid Vision™ fusion vision technology, ALPIX-Eiger™ enables the fusion of image sensing and event sensing at the pixel level, making the simultaneous output of both image and event streams possible.

ALPIX-Eiger ™ is a patented chip architecture and pixel design with advanced 3D stacking and BSI back-illuminated/backlight technology. With a pixel size of just 1.89µm×1.89µm and a resolution of 8.0 megapixels, it is the smallest pixel size and highest resolution image sensor with event-aware capabilities in the industry. It offers broad application capabilities to small-sized smart devices, such as mobile phones and motion cameras.

High performance

The ALPIX-Eiger™ not only maintains the advantages of image sensors, ensuring full image quality and rich image details but also facilitates event sensing through the patented design of digital-analog mixed signal processing in pixels. This technology allows single pixel to work independently to detect light changes. Having a response speed of microseconds, high frame rate (equivalent to 5000fps), high dynamic range (110dB), low data redundancy and other characteristics helps the image sensor obtain more information and enhances image quality.  Compared with previous event camera solutions, the event stream output by ALPIX-Eiger™ carries color information, which aids color reconstruction of the image and achieves better quality photo and video capabilities.

Wide Applications

In practical applications, intelligent imaging devices equipped with ALPIX-Eiger™ chips can achieve high-end functions such as de-blurring, high frame rate, and super-resolution to facilitate the development of more visual applications. The HDR performance and instantaneous response of the ALPIX-Eiger™ also allow the device to obtain better imaging results at night in scenarios with extreme light and dark contrasts.
