PROBLEM TO BE SOLVED: To precisely obtain the position of photographing an image and to perform writing on the image even in an environment where use of a radio wave is not allowed. SOLUTION: The photographing position specifying device includes: an input section 11 for acquiring a photographing instruction and a writing instruction; a photographing section 12 for photographing an object when the photographing instruction is acquired; a storage section 17 for storing positions of at least three terminals in advance; and a light emitting section 13 for emitting light when the photographing instruction is acquired. The photographing position specifying device further includes: a sound wave reception section 14 for receiving a sound wave; a time acquisition section 15 for acquiring the time when the sound wave is received and the time when the light is emitted; and a control section 16 for calculating the distance to each terminal on the basis of the difference between the time when the sound wave is received and the time when the light is emitted and a sound velocity and calculating the position of the own photographing position specifying device; and a writing image acquisition section 51 for generating an image to be written for the photographing result of the photographing section 12 and acquiring it as a writing image. The storage section 17 stores the photographing result, the writing image and the position of the own photographing position specifying device 10a in association with each other.
