Abstract

An information processing device having a touch panel includes an operation part, a display, an operation content determination part, and a display control part. The operation part displays an unlock icon while the display displays the predetermined lock screen in the locked state. The operation content determination part determines whether or not to release the locked state and whether to change the display content of the lock screen in response to a user'"'"'s operation on the unlock icon. The display control part changes the display content of the lock screen based on the determination result. The unlock icon can be moved from the initial position to an end mark along a slide bar via a user'"'"'s operation. The operation content determination part determines the instructed content of a user'"'"'s operation based on the time length of a user'"'"'s operation on the unlock icon or the position of the unlock icon.
