Patent number: 10419694Abstract: An apparatus for imaging an object has a metering image sensor that comprises a plurality of pixels. The plurality of pixels is matrix-arrayed along vertical and horizontal directions. The apparatus also has an image sensor driver that drives the metering image sensor, which reads image-pixel signals of neighboring pixels among the plurality of pixels while mixing the image-pixel signals. The apparatus also has a pixel addition setting processor that sets a number of pixel addition of the metering image sensor with respect to at least one of at least one row and at least one column. The pixel addition setting processor sets different numbers of pixel addition to different pixel areas. The apparatus also has an exposure controller that controls an exposure of the metering image sensor and the photography image sensor.Type: GrantFiled: October 11, 2018Date of Patent: September 17, 2019Assignee: RICOH IMAGING COMPANY, LTD.Inventors: Masakazu Terauchi, Yasuhiro Kazama, Hirotaka Ueno

Patent number: 4516133Abstract: The directivity as well as the gain of an antenna element associated with a finite length reflector, which includes a feed antenna such as a dipole antenna and a reflector having a finite length of several wavelengths or less, are improved by disposing a non-feed loop element having a peripheral length of about 2 wavelengths along a common imaginary plane with the feed antenna so as to surround the feed antenna. Preferably, the non-feed loop element is disposed in parallel to the reflector, and more preferably it is disposed nearly symmetrically with respect to the center of the feed antenna.Type: GrantFiled: September 7, 1982Date of Patent: May 7, 1985Assignee: Japan Radio Company, LimitedInventors: Shigeru Matsumoto, Yoshikatsu Okabe, Yasuhiro Kazama
