The dual-lens model is based on technology from LinX, an Israeli company acquired by Apple last year. LinX had successfully developed miniature multi-aperture cameras designed for mobile devices. The camera modules are nearly half the height of a standard mobile camera and are capable of creating stunning color images and high accuracy depth maps.
Kuo says Apple could use the LinX Imaging algorithm to bring a 2-3x optical zoom function to the iPhone 7 Plus while sidestepping the traditional bottlenecks associated with compact camera module (CCM) assembly.
At this point it's not clear whether Apple is just prototyping two versions of the iPhone 7 Plus or whether the company plans to release both the single lens and dual-lens versions. Perhaps the dual-lens could be an upgrade option, similar to opting for Cellular on the iPad.
Apple is expected to unveil the iPhone 7 later this year. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
