The wiper control apparatus provided in a vehicle and for controlling the wiper operating on the window of the vehicle includes a wiper position detection unit to detect a position of the wiper on the window of the vehicle, a recognition rate calculation unit to calculate a recognition rate of an image taken by an imaging device when the position of the wiper detected by the wiper position detection unit is a previously determined position, a target recognition rate setting unit to set a target recognition rate from the calculated recognition rate, a comparison unit to compare the recognition rate with the target recognition rate and to output a comparison result, and a wiper operation speed determination unit to determine an operation speed of the wiper based on the comparison result.",
