Ambient Light Sensor Boosts Smartphone-Camera Performance

STMicroelectronics’ VD6281 full-color ambient light sensor (ALS) simultaneously provides scene color temperature, ultra-violet (UVA) radiation level, and lighting frequency information. As a result, the sensor lets the camera correct white balance and enhance color presentation and sets appropriate exposure times to avoid flicker artefacts and eliminate banding in pictures and videos, especially in scenes lit with LED sources.

 

Measuring 1.83 mm x 1 mm x 0.55 mm, the VD6281 is thought to be the smallest multispectral ambient light sensor available, allowing integration in bezel-free smartphones with small notches and inside smartwatches. The sensor uses direct-deposition filter material to create six independent color channels: red, green, blue, near-infrared, UVA, and clear.
