  In the digital camera 10 according to the present embodiment, 2 Hz is applied as an example of the vibration frequency. In the digital camera 10 according to the present embodiment, the determination method for determining whether the vibration frequency is less than the predetermined frequency is applied in order to determine whether the user is walking. For example, when the displacement (amplitude) detected by the vibration detection unit 80 exceeds a predetermined threshold, the determination method for determining that walking is in progress, and the walking by combining the amplitude and the vibration frequency. You may apply other determination methods, such as the determination method which determines whether it is inside.

  In step 124, the current position information stored in chronological order is read from the RAM 64, and it is determined whether the current position is fluctuated based on the read current position information. If the determination is affirmative, step 124 is performed. 126.

  In this embodiment, the latitude, longitude, and altitude indicated by the read current position information are given a predetermined amount (in this embodiment, 30 seconds as an example) at a predetermined time interval (in this embodiment, as an example). 3m) It is determined that there is a change in the current position except when there is no more change.

  In the digital camera 10 according to the present embodiment, values set in advance by the user may be applied as the predetermined interval and the predetermined amount.

  In step 126, a predetermined process prohibiting process is executed to prohibit execution of a predetermined process by operating a predetermined switch among switches other than the predetermined switch (release switch 16 in the present embodiment). To do.

  On the other hand, if the determination in step 122 or step 124 is negative, the process proceeds to step 128.

  In step 128, it is determined whether or not execution of the predetermined process is prohibited. If the determination is affirmative, the process proceeds to step 130, and the prohibited predetermined process is restored. On the other hand, if the determination is negative, the process proceeds to step 132 as it is.

  In step 132, it is determined whether or not the release switch 16 has been operated. If the determination is affirmative, the routine proceeds to step 134.

  In step 134, the speaker interface 72 is controlled so as to output a sound corresponding to the type of operation state for the release switch 16. In response to this, the speaker interface 72 outputs sound from the speaker 26.

  In the next step 136, the display state of the LCD 20 is switched according to the type of operation state for the release switch 16, and the process proceeds to step 138.

  Here, Table 1 shows an example of the relationship between the type of operation state for the release switch 16 and the function corresponding to the type (display state by the LCD 20) in the navigation mode. Table 1 also shows the types of operation states for the release switch 16 in the shooting mode in order to clarify the functional difference between when the release switch 16 is operated in the shooting mode and when the release switch 16 is operated in the navigation mode.

表１に示すように、ナビゲーションモードとされた場合に、レリーズスイッチ１６が半押し状態でクリックされると、スピーカー２６から３００Ｈｚの音Ａを出力させた後、ＬＣＤ２０に表示する地図の表示対象位置を前方向（目的地の方向）に移動させる。なお、本実施の形態に係るデジタルカメラ１０では、一例として、レリーズスイッチ１６が半押し状態でクリックされる毎に、上記表示対象位置の移動量として前方向に５０ｍ移動させる場合を適用するが、これに限らず、例えば、２５ｍ、１００ｍ等、他の移動量を適用してもよいし、予め使用者が設定した移動量を適用してもよい。

As shown in Table 1, when the release switch 16 is clicked in a half-pressed state when the navigation mode is set, a 300 Hz sound A is output from the speaker 26 and then the map display target position displayed on the LCD 20 Is moved forward (toward the destination). In addition, in the digital camera 10 according to the present embodiment, as an example, the case where the display switch is moved 50 m in the forward direction every time the release switch 16 is clicked in a half-pressed state is applied. For example, other movement amounts such as 25 m and 100 m may be applied, or a movement amount set in advance by the user may be applied.

  In addition, when the release switch 16 is pressed halfway in the half-pressed state (in this embodiment, as an example, 3 seconds), a sound B of 500 Hz is output from the speaker 26 and then the display range of the map displayed on the LCD 20 is displayed. Enlarge, that is, reduce the reduction scale. In addition, in the digital camera 10 according to the present embodiment, as an example, a case where the reduction scale is multiplied by 1/10 each time the release switch 16 is pressed halfway down is applied. Other magnifications such as 1/5 times or 1/20 times may be applied, or magnifications set in advance by the user may be applied.

  Further, when the release switch 16 is double-clicked in a half-pressed state, after the sound C of 600 Hz is output from the speaker 26, the display range of the map displayed on the LCD 20 is reduced, that is, the reduction scale is increased. In the digital camera 10 according to the present embodiment, as an example, a case where the reduction scale is multiplied by 10 each time the release switch 16 is double-clicked in a half-pressed state is applied. Other magnifications such as 20 times may be applied, or a magnification set in advance by the user may be applied.

  When the release switch 16 is clicked in the fully depressed state, after the sound D of 700 Hz is output from the speaker 26, the scale of the map displayed on the LCD 20 is returned to the preset initial value, and the pointer 96 is moved to the LCD 20 Return to the center of the map displayed at.

  Further, when the release switch 16 is kept fully pressed (in this embodiment, as an example, 4 seconds or more), after the sound E of 1000 Hz is output from the speaker 26, the long press is being continued. The inclination of the apparatus main body is detected by the inclination detection unit 82, and the map displayed on the LCD 20 is scrolled based on the detected inclination direction.

  In the digital camera 10 according to the present embodiment, when the release switch 16 is kept fully pressed and the tilt detection unit 82 detects that the digital camera 10 is tilted in the direction of arrow A in FIG. As an example, the map being scrolled is scrolled forward as shown in FIG. When the tilt detection unit 82 detects that the tilt is in the direction of arrow B in FIG. 3, the displayed map is scrolled backward. Further, when the tilt detection unit 82 detects that the camera is tilted in the direction of arrow C in FIG. 3, the displayed map is scrolled to the left, and when it is detected that the camera is tilted in the direction of arrow D in FIG. Scroll right on the map.

  The digital camera 10 according to the present embodiment applies a case in which the speed at which the displayed map is scrolled is increased as the angle detected by the inclination detection unit 82 increases. For example, the case where the detection time is increased as the time detected by the detection unit 82 becomes longer may be applied.

  On the other hand, if a negative determination is made in the determination process in step 132, the process proceeds to step 138 without executing the processes in step 134 and step 136.

  In the next step 138, it is determined whether or not the user has arrived at the destination by determining whether or not the current position is within a predetermined range including the destination (in this embodiment, 3 m as an example). If the determination is affirmative, the process returns to step 112. If the determination is affirmative, the process proceeds to step 140.

  In step 140, it is determined whether or not the execution of the predetermined process by operating the touch panel 21 is in a prohibited state. If the determination is affirmative, the process proceeds to step 142 and is prohibited. After returning to a predetermined process, the program is terminated. On the other hand, when a negative determination is made, the program is terminated as it is.
