<p><P>PROBLEM TO BE SOLVED: To provide a display device and an information protection program for properly preventing the leakage of secret information to a third person without damaging the convenience of a user. <P>SOLUTION: In a display terminal, when the switching instruction of a screen displayed on a display panel is made (S3), an elapsed time since the screen is switched is measured (S5). Then, when it is determined that the residual battery amount is smaller than a voltage threshold (S7: YES), and that a prescribed time or more has passed since the screen is switched (S9: YES), at least secret data to be prevented from being browsed by a third person among image data stored in a memory card are deleted (S11). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
