PROBLEM TO BE SOLVED: To provide an information transmission system capable of transmitting information simply and in an easy-to-understand manner even when a photographer is concentrated on a subject underwater.SOLUTION: The information transmission system has a camera 10 having an imaging section which images a subject image to output image data and a waterproofing protector 30 storing the camera 10 water-tightly, in which an acceleration detection section 7 which detects acceleration applied to the camera 10 itself, a sound wave transmission section 31 which externally transmits sound wave and a sound wave transmission control section 1b which changes a sound wave pattern on the basis of the acceleration detected by the acceleration detection section 7 are arranged. The sound wave transmission section 31, when generating a signal according to the sound wave pattern changed by the sound wave transmission control section 1b and transmitting the sound wave based on the generated signal to another camera 10, allows another camera 10 or the like to generate an image for transmitting the information and combines the generated image with the subject image displayed in another camera 10 to display the image. |
