Latest Patents

Kawamura holds a patent for an automatic focusing device for a camera that adopts linear sampling. This device includes a camera section with an optical lens system that has a variable focusing position. It features a driver that varies the focus of the lens system. The device captures a desired scene through the lens systems and converts it into a video signal via raster scanning. The signal extracting section defines multiple sampling points arranged to intersect the scanning lines of the video signal. When the raster scanning reaches any of these sampling points, the device extracts and holds the video signal. A computing section then determines the direction in which the focus should be varied, and a control section manages the driver to adjust the focus accordingly.
