Light Co. Talks about L16 Camera Internals

Light Co. posts an update on the progress to mass production of its L16 multi-aperture camera, giving some details on its internal design:

"The ASIC is the “brain” of the camera and is what we use to control all of the L16’s camera modules. Consider that your traditional (non-computational) camera only has to control a single lens and a single sensor as you compose, focus, adjust and capture. The L16 requires simultaneous control of at least 10 discrete cameras (lens barrels, sensors, mirrors, etc.). Needless to say this requires an extremely advanced “brain,” which is why we designed a highly advanced ASIC specifically for this purpose.

There are 3 ASIC’s in each L16 Camera, each made using industry leading semiconductor processes. Each ASIC is comprised of a 533 MHz processor with multiple levels of internal caches and has up to 4GB of DDR memory support. Light has devised a proprietary MIPI data handling mechanism to be very power efficient. In fact, Light’s ASIC has more MIPI camera interfaces than any leading media or application processor in the semiconductor industry. In addition, each ASIC is loaded with Light’s exclusive lens, mirror, and sensor controls that enable the L16 to work its magic. The development of this chip marks major breakthrough and required an enormous amount of effort from the Light team.
