A predominantly software-based system, developed by NEC, that eliminates noise from the autofocus and zoom motors in digital camera videos.
How does it work? At present, focus and zoom motors are slowed or disabled to prevent sounds being collected by internal microphones. With NEC’s new innovation, a microphone and DSP are used to generate “pseudo-noise” to cancel out background buzzing from the camcorder’s own hardware. The method is similar to the one used by noise-cancelling headphones.
Who will be the beneficiaries? Manufacturers and users of small point-and-shoot camcorders and videocapable
