Interview with Martin Wäny
Martin Wäny, the founder and CEO of Awaiba, now CMOSIS, gives an interview on endoscopic imaging to News Medical site. Few interesting quotes:
"The miniaturization, and in particular the usage of semiconductor miniaturization technologies, allows us to build smaller, in volume and lower priced endoscopic cameras. This enables the proliferation of disposable endoscopes for a wide range of applications.
Is it possible to introduce 3D visualization using the mini optical modules?
Yes, for that purpose CMOSIS already offers endoscopic stereo camera modules. Multiple camera modules can provide 3D image information as needed for dental applications, or for the absolute measurement of features in laparoscopy or gastroenterology."

Kogakuin University Video Super-Resolution Said to Exceed Nyquist Limit
Nikkei: Seiichi Gohshi, professor of the Department of Information Design, the Faculty of Informatics, Kogakuin University, and Fujitsu jointly develop a new technology employed for the "Xevic" image processing engine of Fujitsu's Arrows NX F-02H smartphone, to be released in late November 2015. Unlike commonly-used "reconstructed super resolution" and "learning super resolution," the super-resolution technology being researched by Gohshi uses an original method called "nonlinear signal processing method." A nonlinear function is used to supplement high-frequency components and reproduce high-resolution components that surpass the "Nyquist frequency (half of a sampling frequency)," Gohshi said.
The 2014 University research report gives a list of recent publications by Seiichi Gohshi:

Panasonic Post Focus Leverages High Speed Video Mode
PRNewswire: Panasonic leverages its high speed sensor to introduce a Post Focus feature that captures multiple photos with multiple in focus points through a single release of the shutter. Post Focus uses 49-area DFD (Depth From Defocus) autofocus to capture 4K images at 30 fps. The operation of Post Focus function is quite simple and easy – set the camera to Post Focus mode, and press the shutter button. The camera automatically "racks" the focus while capturing photos with varied in focus points. During the playback, one uses the touch screen to select the in focus area desired, and save as a separate 8MP file:
Sony Rises in Semiconductor Company Ranking
