There's more evidence that the larger-screened version of the next iPhone, likely called the iPhone 7 Plus, is going to get a pretty big camera upgrade.

Chinese and Japanese camera lens manufacturers "have sent dual-lens camera samples to Apple for testing," according to a new report from DigiTimes, a publication that has a mixed track record when it comes to reliably reporting Apple rumors.

The DigiTimes report, though, comes just a few days after Ming-Chi Kuo, a reliable Apple analyst at KGI Securities, said that iPhone 7 Plus would indeed come with a dual lens camera.

As we reported last week, a dual lens camera would allow for better pictures in low light, because two cameras can capture more light than just one.

It could also improve the iPhone camera's zoom, according to MacRumors. The new cameras could take advantage of technology from LinX, a startup Apple bought last year for a reported $20 million. LinX has supposedly built technology that can improve the quality of pictures taken with a smartphone to make them more like those taken with bigger, DSLR cameras.

Finally, it could also allow Apple to build the next version of its iPhone without the camera bulging out of it, a feature since the iPhone 6 was released in 2014, because it could allow for a thinner design, according to MacRumors.

Apple takes the iPhone camera very seriously. Graham Townsend, who oversees the iPhone camera at Apple, told Charlie Rose in a recent "60 Minutes" interview that Apple has 800 engineers who work on the iPhone's camera.
