Apple is gearing up to reveal iPhone 7 during its "special event" that will take place in San Francisco on Sept. 7. While rumors are rife, one significant rumor is that the iPhone 7 Plus will sport a dual camera system.
The Cupertino-based tech giant is reputable for investing heavily in its camera technology and the latest rumor could become a unique feature of the upcoming handset, according to Mirror UK. Having two cameras at the back of the device is by no means a new strategy. The recently unveiled LG G5 and Huawei P9 both sport two lenses, and the first ever smartphone to come with this functionality was the HTC Evo 3D, released back in 2011.
However, Apple may be set to improve on what previous manufacturers did with dual camera lenses. The company has hinted on the invitation to the event that the iPhone 7 will create a bokeh effect, with an image of several out-of-focus colored dots outlining the top part of Apple's logo.
The HTC One M8 and Honor 6 Plus rely on dual lenses to create photos with added depth. The second lens on the two devices is meant to capture extra depth information that enables users to have a clear focus in the foreground, while the background remains blurred. This is referred to as bokeh effect used by fashion photographers.
If rumors turn out to be true, each of the 12MP lenses on the new iPhone will come with their own sensor. The sensors could capture slightly different versions of the same still, which can then be combined to create an image that will have optimal contrast and color saturation.
The technique is similar to how Huawei's P9 smartphone uses its dual camera lens, according to the same publication. Positioned at the back of the phone, one lens captures RGB color and the other captures monochrome detail.
The monochrome-only lens enhances the camera's contrast levels, with Huawei claiming that it captures up to 200 percent more light. The company even released the RBG and monochrome sensor combo for its Honor 8 handset, which resulted into producing sharper photos.
In case iPhone 7 follows the same trend, the outcome will be the two lenses working together to create vibrant, punchy stills. Getting best of the two worlds, users' images will have rich colors and sharp definition on the edges.
