<p>A sound-pickup device includes an input unit configured to input a plurality of sound signals, a sound-directivity-generation unit configured to generate a plurality of sound-directional signals in all circumferential directions from the sound signals, a scanning unit configured to scan and output the sound-directional signals in order of directivity directions, and a vector-synthesis unit configured to select at least one specified-direction signal transmitted from the scanning unit and synthesize a specified direction. At least one signal output from the vector-synthesis unit is processed to be a plurality of sound-output channels.</p> |
