Reports monitored by Bloomberg News showed that Apple quietly acquired Spectral Edge, a British startup that specializes in artificial intelligence technology, and was founded by the University of East Anglia in 2014.

The company invented Spectral Edge Phusion in 2016, a photography technology that uses uninterrupted infrared light in the human eye to sharpen smartphone images and restore color, especially in images taken on cloudy days.

Apple has not yet commented on the acquisition, nor the amount it paid for the company.

This is not the first purchase of a company specializing in artificial intelligence by Apple this year. Last July, it bought Drive II, a startup in the field of autonomous technology, valued at $ 200 million. Last March, reports indicated that the US company had bought Lighthouse II, which is powered by artificial intelligence, powered home security cameras.

Apple has a habit of quietly collecting smaller companies. In May last year, CEO Tim Cook said that Apple bought twenty companies within six months, only six of them were known.
