NEC Noise Canceling for camcorder zooms

NEC has developed a process to the sound of the camera motor, which for example when zooming or changing the autofocus during recording on the tape (or card) is, to suppress it. This makes it possible to run faster the zoom without regard to any noise or to place the motor on the housing closer to the internal microphone. So far, the speed of the zoom and auto focus wure often artificially limited to loud noise to avoid during the recording, According to NEC, but what often leads to poor usability in scenes where zooming or a quick change of AF are needed () such as in sports. In addition, moves by the increasing miniaturization of the camcorders zoom / focus motor automatically closer to the built-in microphone and amplifies this problem. When NEC's procedures are the characteristic sounds of each system during zooming and focusing just as involved as age or individual Störgeräuschcharakterisitiken special equipment, The run will be determined in the operation. These sounds are then separated out on the new procedure from the recorded Soud. Use are still not known what camcorder manufacturers NEC's new technology.
