  Displaying an image as an opening screen has the effect of reducing the anxiety and frustration (discomfort) of the user waiting for the reset time, while the same opening screen can be shown each time the power is turned on. This may increase the feeling of irritation.

  Further, in order to make the opening screen more strongly recognized by the user, it may be possible to set the display time of the opening screen longer than the reset time, and the extension of the waiting time may increase the user's frustration.

  Moreover, when the image as an opening screen is the same every time, it is also considered that a user's irritation feeling increases further.

  The present invention was made to solve the above-described problems of the prior art, and the purpose of the display is to enable a user to feel less frustrated when displaying an image as an opening screen. A control method, a display control device, a program, and a storage medium are provided.

  In order to achieve the above object, a display control method of the present invention is a display control method for controlling an image to be displayed as an opening screen for a predetermined time when the power is turned on, the time when the power was last turned off or the power The recording process that records the time when the power is turned on (ON), the comparison process that compares the time recorded by the recording process with the current power-on time, and the opening screen that is displayed based on the comparison result of the comparison process are changed. And a changing process.

  In order to achieve the above object, the display control device of the present invention is a display control device that controls to display an image as an opening screen for a predetermined time when the power is turned on, and the time when the power was turned off last time. Alternatively, recording means for recording the time when the power is turned on (ON), comparison means for comparing the time recorded in the recording means with the current power-on time, and an opening screen displayed based on the comparison result of the comparison means And changing means for changing.

  According to the present invention, since the image as the opening screen displayed according to the time interval of power ON (ON) / OFF (OFF) changes, the user is frustrated when displaying the image as the opening screen. It becomes possible to reduce.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The feature of the present invention is to record the time when the power is turned off (OFF) or the time when the power is turned on (ON), compare the recorded time with the current power-on time, and display based on the comparison result. It is to change the image as the opening screen.

  Further, the present invention is characterized by controlling whether or not to display an image as an opening screen based on a comparison result between the recorded time and the current power-on time, and an arbitrary value as a comparison reference in the comparison process Is set and the arbitrary value is recorded.
