Apple’s “Biggest Camera Jump Ever”: Dual Lens Camera For DSLR Quality Photos
Apple’s done it again. It seems that the world dominant tech giant just can’t get enough of the headlines it attracts. While still in jeopardy regarding the dramatic ratio between demand and supply of the flagship iPhone 6 Plus, Apple is still not letting this factor hinder their progress in upgrading of the model.
In the next generation iPhone after iPhone 6 and 6 Plus, two dual lenses will be incorporated into the phone, according to John Gruber from Daring Fireball.
“The specific thing I heard is that next year’s camera might be the biggest camera jump ever,” Gruber said. “I don’t even know what sense this makes, but I’ve heard that it’s some kind of weird two-lens system where the back camera uses two lenses and it somehow takes it up into DSLR quality imagery.”
This trend of using multi-lens imaging systems to replace the small form factor of smartphones is a recently implemented technique. HTC was the first to integrate dual cameras in its flagship One M8, in which a standard sensor is merged with an “ultrapixel” sensor that lets in more light to improve image quality. The secondary lens then provides additional image information to the first lens, and allows shifting focus.
Corephotonics, a start-up marveling in compact camera design and computations, proposed a different technique of dual camera imagery. Earlier this year, Corephotonics created a dual lens module which has two distinct focal lengths, allowing catering to the resolution drops caused by digital zooming.
In simpler words, one camera is used for wide shots, and the other for close-ups. As an added bonus, the system provides spatial data for 3D imagery due to its lens offset.
After the announcement that dual cameras will be featured in the upcoming iPhones, it is highly being speculated that Apple could employ a similar system. Another speculation is that the image layers from both cameras could be piled up together to form a DSLR quality resolution image.
Apple has a lot of liberty when it comes to cameras, since the company has stacks of patents which cover smartphone camera technologies, like refocusing, interchangeable modules and interchangeable external lenses.
We are expecting a multi-sensor system that gathers luminance and chrominance values separately, and creates the resulting photos at exceedingly high resolutions and high color accuracy.
