Spectral ALS sensors to enhance the performance of the next generation of high-end smartphone cameras

     Ams has introduced the AS7350, the most advanced spectral ambient light sensor (ALS) on the market for high-end mobile phone cameras. The new sensor is capable of delivering high quality images, even in cases of extreme color contrast, or in non-ideal/mixed light source conditions, enabling professional grade photography with consumer devices. The AS7350 achieves this for the first time by enabling light source identification through spectral reconstruction, achieving unprecedented automatic white point balance accuracy in any light condition.

     Driven by consumers' desire for more advanced camera features, mobile phone manufacturers are constantly striving to differentiate themselves by improving image quality. Whether it's sharing a video on social media or taking the perfect landscape shot, photography through advanced camera features is the killer app in today's smartphones and a major point of market differentiation for phone manufacturers. Driven by consumer demand for more advanced camera features, mobile phone manufacturers are constantly striving to differentiate their devices by improving image quality. By selecting the premium AS7350 spectral ALS sensor, Oems have a competitive advantage that can help maximize sales and limit competitive market risk.

     By accurately identifying ambient lighting conditions, the AS7350 delivers unmatched image quality even in high-color contrast scenes and helps vendors continue to deliver professional-grade camera quality in mobile devices. Reiner Jumpertz, vice president and general manager of the Color and Spectral Sensors business line at ams, said: "For many consumers, camera performance is the decisive factor in choosing a quality phone: They conduct in-depth research on the model, guided by professional testing and user reviews. We believe this is a turning point in the use of consumer devices to achieve professional image quality, and smartphone vendors can now use the AS7350 spectral ALS to detect and identify ambient light sources to obtain very accurate white balance information (above or beyond normal RGB sensors), giving them world-class image quality customers."

     Professional photographers understand the impact of different light sources on photo quality and color effects. White dot balance is one of the core functions of modern photography, which can compensate the distortion effect of the image to the ambient light and process the color. Advanced white point balancing capabilities for consumer devices enable features previously reserved for the professional camera market. The AS7350 recognizes any type of light source, including daylight, incandescent, fluorescent, all types of leds and any combination of them.

     The most advanced spectral ambient light sensor on the market has 11 channels, 8 equal-pitch visible light, 1 flicker, 1 near-infrared and 1 clear channel, all in a small LGA package of 3.1 mm x 2.0 mm x 1.0 mm. The scintillation channel detects artificial light sources with a scintillation frequency of 50 Hz to 3 KHZ and above, depending on the implementation.
