<p>A pickup signal processing apparatus, provided with: a voice judgment unit (150) which judges whether pickup signals picked up by microphones (111, 112) are voice signals which include voice from a nearby sound source or are background noise signals which do not include voice; signal level calculation units (131, 132) which calculate the respective signal levels of the plurality of pickup signals that the microphones pick up; a setting unit (160) which, in the case that the pickup signals are judged to be background noise signals, determines from thesignal levels of the plurality of pickup signals, a gain value reducing the difference of signal levels between the microphones, and which sets that value as the gain value of the pickup signal of at least one of the microphones, said gain value being a value that the pickup signal of at least one microphone among the microphones (111, 112) is to be multiplied by; and computing units (121, 122) which multiply the pickup signal of at least one of the microphones by the gain value.</p> |
