Spectral ALS focuses on premium phone cameras

Claimed to be the world’s most advanced spectral ambient light sensor (ALS) for high-end mobile phone cameras, the AS7350 enables the highest quality images even in situations with extreme colour contrast, or under non-ideal/mixed light source conditions, says ams. As a result, says the company, professional grade photography is possible using a consumer device.

The AS7350 enables light source identification via spectral reconstruction to achieve unprecedented automatic white-point balancing accuracy under any light conditions, claims ams.

Whether sharing videos on social media or capturing that perfect scenic shot, photography is a major point of market differentiation for mobile phone manufacturers.

White-point balancing, compensating the image’s treatment of colour for the distorting effects of ambient light is one of the core functions of advanced photography. The AS7350 identifies any type of light source, including daylight, incandescent, fluorescent, all types of LEDs, and any combination of these. The  spectral ALS features 11 channels, eight equally spaced in the visible, one flicker, one near infrared (NIR) and one clear channel in a tiny 3.1 x 2.0 x 1.0mm LGA package.

The flicker channel detects artificial light sources with flicker frequencies from 50Hz to 3kHz and beyond, depending on implementation.

The AS7350 will be available for sampling in first quarter of 2020. ams als offers a full enablement suite.

Ams designs and manufactures advanced sensors. It says its mission is to shape the world with sensor solutions by providing a seamless interface between humans and technology.

ams’ high-performance sensor solutions drive applications requiring small form factor, low power, highest sensitivity and multi-sensor integration. Products include sensor solutions, sensor ICs, interfaces and related software for consumer, communications, industrial, medical, and automotive markets.

With headquarters in Austria, ams employs about 9,000 people globally and serves more than 8,000 customers worldwide.
