Watch a one-hour webinar to discover the tiny VD6283 multispectral color sensor, the newest addition to ST's Ambient Light Sensor (ALS) family with advanced light flicker extraction.

This ultra-sensitive ALS device performs fast and accurate light measurement thanks to an individual ADC and a readout for each color channel. The VD6283 uses hybrid color filters with precise responses which enhance the accuracy of the correlated color temperature (CCT) and Lux performance. The device can be used to assist camera white balance in less than 30 ms.

With a patented architecture and a high-performance photodiode design, the VD6283 can extract light flickering frequencies to enhance camera experience and avoid “banding effects” on videos or viewfinder modes. Additionally, the VD6283 is the only sensor able to extract different light flicker waveforms, including LED square signals, that can run flicker operations simultaneously with ALS operations.

You will learn:

  • How to resolve the challenges that rolling shutter cameras have with LED lighting
  • How the sensor's tiny footprint (1.83 x 1.0 x 0.55 mm) allows accurate Lux measurement without taking up valuable real estate in your design
  • How to measure correlated color temperature (CCT) for optimal image color rendering
