An input apparatus includes: an operation position determination device that determines an operation position of a gesture operation by a user; a movement vector calculator that calculates a movement vector at an input position on the basis of a movement amount of the operation position when the operation position moves; an input processor that executes first input processing at the input position at the time when a first gesture operation is detected, and executes second input processing at the input position at the time when a second gesture operation is detected; and a movement vector corrector that corrects the movement vector in the case where a change from the first gesture operation to the second gesture operation is determined.
