Document Type and Number:
Japanese Patent JP6979536
Kind Code:
B2
Abstract:
Provided are a sound signal processor, a sound signal processing method, a sound signal processing program, a sound signal processing system, and an imaging device with which it is possible to appropriately recognize a sound produced by a subject of observation. A video from a camera (10) that captures the inside of an area being observed from a fixed position is displayed on a display (112). Designation of a position in the video displayed on the display (112) is accepted, and the subject of observation is set. A positional relationship between the set subject of observation and a plurality of microphones (Mij) arranged discretely in the area being observed is calculated. An arrival time until a sound uttered by the subject of observation arrives at each of the microphones (Mji) is calculated on the basis of the calculation result. Sound signals from the microphones (Mij) are synchronized, superimposed, and emphasized on the basis of the calculation result, and then are outputted from a speaker (114).
