The display screen includes a photographic image display window 351, a photographic attachment information display window 352, and click boxes 353a and 353b. In the captured image display window 351, the main image 253 stored in the image file 250, that is, the captured image is displayed, and a translucent arrow image 354 representing the relative wind direction and wind speed obtained in FIG. 7 is superimposed. Is displayed. In the shooting attachment information display window 352, the contents of the Tag information of the image file 250 are displayed.
[0034]
The user can select the display / non-display of the arrow image 354 by operating the click boxes 353a and 353b. The selection operation is performed using an input device such as a mouse connected to the personal computer 300. In the illustrated example, when the arrow image 354 is displayed, the click box 353b of “do not display wind direction and wind speed” is active, and the click box 353a of “display wind direction and wind speed” is inactive (grayed out display).
[0035]
The length of the arrow image 354 is proportional to the wind speed. That is, the arrow images 354 having different lengths according to the wind speed are displayed. Therefore, for example, when the wind direction is the same as in FIG. 8 and the wind speed is half, that is, 4 m / s, the display is as shown in FIG.

[0037]
In addition, since the measurement data of the wind direction and the wind speed at the time of shooting can be superimposed on the captured image and displayed on the monitor LCD 203 of the digital camera 200, the wind direction and the wind speed at the time of shooting each captured image can be easily obtained at the shooting site. Can be confirmed.
[0038]
Further, by using the digital camera 200, measurement data of wind direction (absolute wind direction) and wind speed and measurement data of shooting direction can be included in the shooting accessory information and recorded in the memory card 212 together with the shot image. Based on the wind direction (absolute wind direction) recorded on the memory card 212 and the shooting direction, the relative wind direction based on the shooting direction can be calculated.
[0039]
Further, the image data 250 recorded in the memory card 212 is read out by the personal computer 300, and the relative wind direction with respect to the object to be photographed is obtained from the measurement data of the wind direction (absolute wind direction) and the photographing direction included in the image data 250, and the relative data is obtained. Since the arrow image 354 representing the wind direction and the wind speed is generated and the arrow image 354 is superimposed on the photographed image and displayed on the monitor 350 of the personal computer 300, the wind direction and the wind speed acting on the photographing object at the time of photographing. Can be grasped intuitively by looking at the image displayed on the monitor 350.
[0040]
In the above embodiment, the personal computer 300 is provided with an image display device having a function of generating an arrow image 354 representing a wind direction and a wind speed relative to an imaging target and displaying the arrow image 354 superimposed on the captured image. However, the digital camera 200 may have the function of this image display device.
[0041]
In the above embodiment, the arrow image 354 is displayed as a wind image representing the relative wind direction and wind speed with respect to the photographing target. However, a wind image reminiscent of a more realistic wind is displayed. Alternatively, an arrow representing wind may be displayed as a moving image. Further, the wind image does not necessarily need to be translucent.
