Patent EP-0279423-A2 (EP)
Inventor: MURASHIMA HIROTSUGU
IPC: H04N5/232
Filed: 1988-02-17
Abstract: In an automatic focusing circuit of a video camera, an automatic focusing operation is performed in response to a first focus evaluating value which is steeply changed and a second focus evaluating value which is gently changed, in response to the position of a lens, generated in response to a video signal obtained in an image sensing circuit 4. When a comparator 28 determines that the first focus evaluating value does not reach a predetermined reference value, an in-focus state detecting circuit 24 and a focusing motor control circuit 10 perform an intermittent automatic focusing operating every other field in response to the second focus evaluating value. When the comparator 28 determines that the first focus evaluating value exceeds the predetermined reference value, the in-focus state detecting circuit 24 and the focusing motor control circuit 10 perform an automatic focusing operation more frequently every field in response to the first focus evaluating value. The moment the change of an object is detected after the object is in focus, the automatic focusing operation is resumed in response to the second focus evaluating value.

Abstract: An optical fiber connector (20) includes two plug assemblies (37-­37) each including a cylindrically shaped plug (40) extending from within a cap (70). An end of each cap is adapted to be secured to a coupling housing (92) to cause the plug which extends from the cap to be received in a sleeve (105) disposed in the housing. An optical fiber cable (22) extends through a cable entrance end of the cap and has an end portion of its optical fiber terminated by the plug. An extender (85) of the cap is secured thereto and extends along the cable a distance to a location where portions (91-91) thereof are closely adjacent to the cable. Bending forces applied to the cable are transferred at the location to the extender and thence to the cap. This avoids the transfer of those forces to the plug which otherwise could cause the plug to turn pivotally about an interior lip of the cap and result in an optical disconnection of the plug from the other plug in the sleeve.

Abstract: In a known device, three-dimensional filterings are carried out in the luminance channel and in the chrominance channel in such a manner that both the luminance and the chrominance component are unambiguously allocated spaces in the three-dimensional frequency space. PAL coding and decoding is effected in conventional manner by means of quadrature modulation and quadrature demodulation, respectively. In the novel device, the loss in bandwidth of the luminance component caused by the three-dimensional filtering is to be reduced. For this purpose, the PAL-modulated chrominance signal is subjected to a multi-dimensional residual side band filtering in the coder. In order to largely reduce or to avoid mutual crosstalk between the colour difference signals at the receiving end, the colour difference signals are low-pass-filtered in the direction of vertical frequencies during the multi-dimensional filtering.
