Light Camera Demo

Mashable got a chance to see Light Co's L16 52MP array camera prototype at CES 2016. Few quotes from Mashable impressions:

"On the prototype, the photo stitching took a little while to work and froze. In the end, I didn't get to see how fast it was. When I asked Dr. Rajiv Laroia, Light's co-founder and Chief Technology Officer, how long it will take to generate a 52-megapixel image on the final product, he told me they're shooting for under a minute.

That's a long time to wait for a complete image. The Light team is going to try to make the processing as fast and instantaneous as possible, but the company's not promising anything faster than under a minute right now."

"I have to admit, the sample image taken by the L16 looked pretty good with lots of details when zoomed in, but it also looked like it had a lot of image noise."

NVIDIA Presents Deep Learning Automotive Imaging Platform

NVIDIA launches NVIDIA DRIVE PX 2, said to be the world’s most powerful engine for in-vehicle artificial intelligence. DRIVE PX 2 can process the inputs of 12 video cameras, plus lidar, radar and ultrasonic sensors. It fuses them to accurately detect objects, identify them, determine where the car is relative to the world around it, and then calculate its optimal path for safe travel.

The company's Youtube promo video presents the new processor:

Socionext Shipping Dual Camera Image Processor

PRNewswire: Socionext (Fujitsu + Panasonic Semi) introduces “M-12MO” (MBG967) Milbeaut Image Processor. The MBG967, which will be available in volume shipments starting in January, is mainly targeted at smartphones and other mobile applications. It supports dual camera, the latest trend in mobile applications, along with functionalities such as low light shot and depth map generation. The expansion of dual camera capabilities in the mobile camera market has been highly anticipated because dual cameras enable new functionalities previously considered difficult with mobile cameras. These include low light shot, which integrates images from color and monochrome sensors, and the generation of depth maps, which can create background blur comparable to that of SLR cameras.

Main features of the MBG967 include:

Low light shot by dual camera: By integrating the images from color and monochrome image sensors, the MBG967 enables high-sensitivity, low-noise pictures:

High-speed, high-accuracy auto focus supports high speed “Phase Detect AF”, in addition to conventional “Contrast AF”. The MBG967 also supports “Laser AF” which has an advantage in the low light conditions. Its “Super Hybrid AF” utilizes these three AF methods in combination, always allowing faster and more accurate AF in varying conditions:
