<p><P>PROBLEM TO BE SOLVED: To present an execution state of an application without guarantee of an operation to a user among applications used as objects for execution. <P>SOLUTION: If the user specifies the application when an operation picture is displayed in a second display hierarchy 162 of a display part 16, a CPU 11 determines whether or not the specified application is an external application. When the specified application is not the external application, the CPU 11 excludes the operation picture, executes a specified internal application, and displays an image corresponding to its request in the second display hierarchy 162. When the specified application is the external application, the CPU 11 displays a trial image showing that execution of the external application is being tried in a first display hierarchy 161 in front in the visibility direction rather than the second display hierarchy 162 which displays the operation picture. The CPU 11 tries the execution of the specified external application, measures a period in which there is no display request, and when the period exceeds a threshold, the CPU 11 eliminates the trial image displayed in the first display hierarchy 161 to display an error image. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
