MENLO PARK, Calif., June 14, 2016 — NIR Camera SensorInvisage Technologies Inc. has announced the Spark4K NIR camera sensor for Internet of Things devices.

The 1.1-μm pixel, 13-MP sensor in a 1/3-in module features 4K video at 30 fps, ideal for augmented reality, autonomous and authentication systems that require high resolution, high dynamic range NIR imaging with global shutter capability.

The sensor features 35 percent quantum efficiency, enabling accurate detection of a brighter, shorter LED pulse that instantaneously outshines ambient IR light to help devices navigate and learn about their environments more accurately in pitch darkness or direct sunlight. Applications include depth sensing, 3D mapping, compositional analysis, authentication and gesture tracking.

Spark4K's ability to detect variations to IR light patterns with greater sharpness allows autonomous and augmented reality devices to perform with enhanced accuracy.


GLOSSARY
camera
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
