A touch panel control device includes: a first determiner to compare a touch level value at each of coordinates along a detection surface of a touch panel, with a first threshold value, to thereby determine presence or absence of an operation for the touch panel; a second determiner to compare, when the first determiner determines the presence of the operation for the touch panel, the touch level value in the operation with a second threshold value, to thereby determine whether the operation is valid or invalid; and a threshold-value changer to change the second threshold value. When the second determiner compares the touch level value in the operation with the second threshold value and determines that the operation is valid, the threshold-value changer changes the second threshold value in the middle of the operation.
