VEML6040 RGB Digital Sensor Slide 4

Where are RGB sensors used? Digital cameras use sensors like the VEML6040 for automatic white balancing. With so many possible light sources, an RGB sensor is needed as an input to the digital processor for white balancing. Making sure whites in daylight are rendered as whites and not blue or orange. The VEML6040 will be used to actively monitor the output of white LEDs since their color changes over time and temperature. The VEML6040 might also be used to determine the ambient color temperature so LCD displays automatically adjust for their white balance.
