Abstract
A microphone array system includes a camera that images a picture for a target place, and a microphone array that picks up sound. A sound source position is calculated based on the picked up sound. An image is displayed on a display, the image including an imaged target place picture and a sound source position mark indicative of the sound source position. An instruction of a specified spot is received in the target place picture displayed on the display. Sound directivity is formed in a direction from the microphone array toward the specified spot based on the picked up sound, and sound data is generated by emphasizing sound in the direction in which the sound directivity is formed. The generated sound data is output to the speaker to reproduce the sound data.
