General Description

The AS7350 is the market’s most advanced spectral ambient light sensor (ALS) for high-end mobile phone cameras and camera-based consumer devices. The sensor enables the highest quality images even in situations with extreme color contrast, or under non-ideal/mixed light source conditions, enabling professional-grade photography using a consumer device.

For the first time, the AS7350 achieves this by enabling light source identification via spectral reconstruction to achieve unprecedented automatic white-point balancing accuracy under a variety of light conditions. By accurately identifying ambient light conditions, the AS7350 enables unparalleled image quality even in high color contrast scenes and helps vendors continue on the path to delivering professional-grade camera quality in mobile devices.

The AS7350 identifies a variety type of light source, including daylight, incandescent, fluorescent, all types of LEDs, and any combination thereof. The sensor features 11 channels, 8 equally spaced in the visible, 1 flicker, 1 NIR, and 1 clear channel, all in a tiny 3.1mm x 2.0mm x 1.0mm LGA package. The flicker channel detects artificial light sources with flicker frequencies from 50 Hz - 3 kHz and beyond, depending on the implementation.

This product suits for the following applications:

  • Image Enhancement
  • Spectral Light Source Detection
