Abstract:
PROBLEM TO BE SOLVED: To provide an all-sky camera device that takes an all-sky image, obtains a sound with a microphone to generate a three-dimensional sound field, and reduces the possibility of breakage of a microphone, suppress an increase in arithmetic processing, and minimizes cost increase to obtain a three-dimensional sound field with realistic feeling.SOLUTION: A line segment 400 that connects a pair of first directional microphones 4A and 4B is positioned on the side of a front panel part 10, and a line segment 401 that connects a pair of second directional microphones 4C and 4D is positioned on the side of a rear panel part 11 side, such that the line segments are located in a twisted relationship with a camera housing 1 interposed therebetween. In a case in which the pair of first directional microphones 4A and 4B and the pair of second directional microphones 4C and 4D are disposed as described above, even when the number of microphones is limited to four in total, it is possible to direct the directivity of sound pickup to all directions.SELECTED DRAWING: Figure 4
