Abstract: A mobile terminal device receives an input of a pressing operation when an operation surface is pressed. A pressing amount detecting unit detects whether or not the operation surface has been pressed. A grip determining unit determines whether or not the housing has been gripped by a user. A threshold adjusting unit adjusts a press detection sensitivity of the pressing amount detecting unit when the housing is gripped by the user and when the housing is not gripped by the user. By this means, it is possible to provide an input device which adequately detects a pressing operation, and a program which is executed by this input device.
