PROBLEM TO BE SOLVED: To provide an image display device which can visualize a position of a sound source while suppressing deterioration of precision in specifying the position of the sound source, and shortening a time required for specifying the position of the sound source. SOLUTION: The image display device is provided with: a display means which displays a photographed image taken by a camera 17 on a display region 71A; a sound collecting means which consists of a pair of microphones M1, M2 arranged in a predetermined interval; a correction temperature setting means which establishes a temperature to correct a propagation speed of a sound collected by the sound collecting means; a sound source position calculation means which calculates the position of the sound source emitting the sound based on a time difference which the sound reaches to a pair of microphones, and the corrected temperature established by the correction temperature setting means; a correlation means which correlates the position of the sound source calculated by the sound source position calculation means, with the display position in the photographed image displayed in the display region corresponding to the position of the sound source; and a display control means which controls to display the image identifying the position of the sound source in the display position correlated with the position of the sound source by the correlation means.
