Abstract:
1. A photographing device adapted to perform a photographing operation underwater, the photographing device comprising: an operation switch that initiates the photographing operation responsive to a manual user operation of the operation switch; a photographing unit that obtains a subject image as image data during the photographing operation; a pressure sensor that detects a water or air pressure on the photographing device; a detection unit that detects whether the photographing device is placed in water or in air; a storage unit that stores image information; and a controller that (1) generates an image file on the basis of the image data and stores the image file in the storage unit, (2) starts an operation of generating time-series pressure data on the basis of output of the pressure sensor when the photographing device enters a first state, in which movement of the photographing device from air into water is detected from an output of the detection unit, (3) stops the operation of generating the time-series pressure data when the photographing device enters a second state, in which movement of the photographing device from water into air is detected from an output of the detection unit, (4) associates any image files stored in the storage unit during a time from entering the first state to entering the second state with the time-series pressure data, and (5) stores again the any image files in the storage unit, wherein responsive to a manual user operation of the operation switch, the controller functions to store the image file generated on the basis of the image data in the storage unit, wherein when the second state is detected, the controller functions to read out the any image files generated during the time from entering the first state to entering the second state from the storage unit, and wherein the controller associates the any image files stored in the storage unit with the time-series pressure data by adding the time-series pressure data to a header section or a footer section of each of the read-out image files, to generate modified image files.
