When it is determined that the clock setting is completed, the controller 130 ends the clock setting function.

  On the other hand, if it is determined in step S303 that the contents of the clock setting item have not been changed from the default state, the liquid crystal display 123 displays a confirmation screen for setting the clock as shown in FIG. 7 (S305). The confirmation screen for not setting a clock displays a content for confirming that the clock is not set by the user. At this time, the user can select “Yes” or “No” by operating the selection button 203. When the user selects “Yes”, the controller 130 sets the clock setting contents in the default state, and determines that the clock setting is completed (S306). When it is determined that the clock setting is completed, the controller 130 ends the clock setting function. On the other hand, if the user selects “No”, the controller 130 returns the operation to step S302. In this way, since the liquid crystal display 123 displays a confirmation screen in which the clock is not set, even if the user accidentally presses the enter button 205 without changing the clock setting, Can be easily set.

  If it is determined in step S306 that the clock setting has been completed, the controller 130 displays an overview of the clock setting resetting procedure on the liquid crystal display 123 as shown in FIG. 8 (S307). Details of the resetting procedure will be described later. At this time, when the enter button 205 is pressed, the liquid crystal display 123 starts the through image display of FIG. 9 (S308). In this way, by showing the user the reset procedure at the end of the clock setting function that is automatically started when the power is turned on, the user erroneously enters the date and time on the clock setting screen that is automatically displayed when the power is turned on. Even if it ends, you can know the procedure for resetting. Therefore, the user can easily reset the clock setting.

  Details of the clock setting resetting procedure will be described. FIG. 10 is a screen transition diagram when executing the clock setting resetting procedure in the digital camera 100 according to the first embodiment. First, the user presses the decision button 205 of the selection button 203 to display the menu screen D900 on the liquid crystal display 203. The menu screen is a screen on which tabs divided into groups for each function such as shooting, playback, and various settings and various setting items belonging to each tab are displayed.
