Within the fiercely contested smartphone market, images generally is a key battleground. Alongside the insatiable needs for higher batteries, sturdiness, storage, and processing, digital camera high quality consistently ranks as a key issue when selecting a telephone.
At CES 2023, Spectricity, a startup based mostly in Belgium, unveiled a brand new entrant to the competitors: the S1 chip.
Spectricity claims the S1 is the primary really miniaturised and mass-manufacturable spectral picture sensor for cell units — and the corporate is targetting sector dominance. Inside two years, Spectricity boldly predicts the sensor will probably be inside each smartphone.

The bullishness derives from a singular focus: measuring “true color” in smartphones. In line with Spectricty, that is one thing that even the very best smartphones nonetheless can’t do.
The issue stems from shortcomings of their white stability software program, which is used to take away unrealistic color tones. Our pure imaginative and prescient system does this remarkably nicely. Once we see a white wall underneath daylight or a fluorescent lamp, our mind adjusts the color temperatures to make each scenes seem white. Smartphones try to do the identical factor, however the outcomes are sometimes disappointing.
“None of those cameras can recognise true color.
Restricted by the three RGB color channels of purple, inexperienced, and blue, their auto-white balancing algorithms wrestle to right unnatural color temperatures. Consequently, images taken underneath incandescent bulbs can seem extra orange than underneath daylight, whereas shady areas can look bluer.
“Regardless that there’s lots of processing energy behind these cameras, none can recognise true color,” Spectricity CEO Vincent Mouret tells TNW.
To resolve this subject, the S1 sensor makes use of extra filters to analyse the spectral signature of an object. After sensing the sunshine supply in a picture, the system corrects the colors accordingly.
Spectricity confirmed TNW the results in a stay demo. Underneath totally different lighting situations, the images produced by the S1 had been in comparison with images taken by high-end smartphone cameras.
Though the outcomes of demos aren’t all the time replicated in actuality, the colors rendered by the S1 appeared much more constant underneath various illuminations.
“With our answer, you may have the identical colors regardless of the lighting situation,” says Spectricity software engineer Michael Jacobs.
The ambitions for the sensor prolong past higher images. Because the S1 can seize the total seen and near-infrared vary at video charges, the imager may improve quite a few cell functions. Spectricity envisions utilizing the sensor for distant cosmetics, e-commerce, ID verification, skin-health evaluation, and even good gardening.
A key element of those plans is the S1’s improved rendering of pores and skin tones. Smartphone cameras are notoriously bad at capturing darker pores and skin, which limits the inclusivity of images. It additionally inhibits any apps that use pores and skin evaluation, from melanoma detection to digital make-up.
The S1’s recognition of darker pores and skin may broaden entry to the advantages.
Smartphone giants are additionally ploughing fortunes into color constancy, however Specriticity says they nonetheless can’t compete with the S1 sensor. This confidence emanates from an extended and slim scientific focus.
Spectricity started life as a spin-out of the Interuniversity Microelectronics Centre (IMEC), a analysis lab for nanoelectronics and digital applied sciences. This connection has helped the startup amass 19 granted patents and 66 lively functions, in addition to 13 PhDs of their crew.
To commercialise the improvements, Spectricity has arrange a high-volume manufacturing line on the X-FAB foundry — which is now prepared for mass manufacturing.
The S1 is presently underneath analysis by main smartphone makers. Amid a global decline in cell gross sales, Spectricity is betting that the sensor affords them an irresistible edge.
