Research on Autofocus Recognition of the LAMOST Fiber View Camera System Under Front and Back Illumination In the closed-loop detection system of the LAMOST, the lens of the fiber view camera system must focus the end of the optical fiber to accurately acquire t... Z Zhou,J Liang,S Duan,...
Autofocus camera adjusting focus lens position based on illumination characteristicsA CPU calculates integrating values of image-capturing signals in a band obtained by removing through a band pass filter a low frequency component of image-capturing signal output from an image-capturing device and ...
iPhone 11 camera issue This camera was letting me take pictures by pressing the buttons on each side of the phone at the same time, now it’s just screen-shorting everything, including the camera options/frame that you see when you open the app. Not sure if any one else has had this ...
Apple on Tuesday was granted a U.S. patent describing multiple methods of creating a self-adjusting Apple Watch band, designs that could one day replace magnetic clasps, velcro and other fasteners seen in current generation hardware. As assigned by the U.S. Patent and Trademark Office, Apple'...
