Recording medium, mobile electronic device, and operation control method

Abstract

A processor of a mobile terminal refers to an app table that stores a reference flag on a per-app basis, the flag indicating whether the operation-unlock app screen is to be displayed in the foreground window of a display. Furthermore, the processor acquires from the app table the flag that corresponds to the current app in response to a lighting-off command. Moreover, the processor determines whether the operation-unlock app screen is to be displayed in the foreground window instead of the current app screen on the basis of the acquired flag. On the basis of the result of the determination, the processor controls the changing of a screen in the foreground window.

What is claimed is: 
     
         1 . A mobile electronic device comprising:
 a display; and   a processor coupled to the display, wherein the processor executes a process comprising:   turning off a screen of the display when a predetermined time period passes without any operation inputs or when receiving a lighting-down command;   determining whether a predetermined application screen is displayed on the display at a time of the turning off; and   when receiving a re-lighting operation after the turning off, displaying the predetermined application screen on the display when it is determined that the predetermined application screen is displayed on the display at the time of the turning off and displaying a screen-unlock application screen to receive an unlock operation on the display when it is determined that the predetermined application screen is not displayed at the time of the turning off.   
     
     
         2 . The mobile electronic device according to  claim 1 , wherein the process further comprises:
 when receiving an operation to the predetermined application screen displayed on the display,
 performing a process to scroll, zoom in, or zoom out, when the received operation is an operation to scroll, zoom in, or zoom out, and 
 displaying the screen-unlock application screen on the display when the received operation is an operation other than the operation to scroll, zoom in, or zoom out. 
   
     
     
         3 . A non-transitory computer readable recording medium having stored therein an operation control program causing a mobile electronic device to execute a process comprising:
 turning off a screen of a display when a predetermined time period passes without any operation inputs or when receiving a lighting-down command;   determining whether a predetermined application screen is displayed on the display at a time of the turning off; and   when receiving a re-lighting operation after the turning off, displaying the predetermined application screen on the display when it is determined that the predetermined application screen is displayed on the display at the time of the turning off and displaying a screen-unlock application screen to receive an unlock operation on the display when it is determined that the predetermined application screen is not displayed at the time of the turning off.   
     
     
         4 . The recording medium according to  claim 3 , further comprising
 when receiving an operation to the predetermined application screen displayed on the display,
 performing a process to scroll, zoom in, or zoom out, when the received operation is an operation to scroll, zoom in, or zoom out, and 
 displaying the screen-unlock application screen on the display when the received operation is an operation other than the operation to scroll, zoom in, or zoom out. 
   
     
     
         5 . An operation method that causes a mobile electronic device to execute a process comprising:
 turning off a screen of a display when a predetermined time period passes without any operation inputs or when receiving a lighting-down command;   determining whether a predetermined application screen is displayed on the display at a time of the turning off; and   when receiving a re-lighting operation after the turning off, displaying the predetermined application screen on the display when it is determined that the predetermined application screen is displayed on the display at the time of the turning off and displaying a screen-unlock application screen to receive an unlock operation on the display when it is determined that the predetermined application screen is not displayed at the time of the turning off.   
     
     
         6 . The method according to  claim 5 , further comprising
 when receiving an operation to the predetermined application screen displayed on the display,
 performing a process to scroll, zoom in, or zoom out, when the received operation is an operation to scroll, zoom in, or zoom out, and 
 displaying the screen-unlock application screen on the display when the received operation is an operation other than the operation to scroll, zoom in, or zoom out.
