  • Sound pickup apparatus
    Patent number: 8103018
    Abstract: An A/D converter sets a sound pickup signal to low sensitivity and inputs the signal to a sound pickup beam generation unit. The A/D converter sets a sound pickup signal to high sensitivity and inputs the signal to the sound pickup beam generation unit. A sound detector determines from the sound pickup beam whether or not sound is present and whether or not clipping has arisen. A control unit inputs a determination result from the sound detector, thereby setting an encoder such that a low-level sound pickup beam signal is output to the outside when a high-level sound pickup beam signal is clipped.
