The objective is to provide a correction algorithm, specifically for an input device and a display device. [Solution] The present invention comprises: a means for executing zero-point adjustment with respect to a sensor output of each load sensor when an absolute value of an amount of change of the output of each load sensor is equal to or lower than a predetermined threshold value (alpha) for a predetermined measuring period; a means for calculating positional data using the sensor outputs of the respective load sensors, and calculating the total load (Z) of the respective load sensors; a means for determining that the calculated data is normal when the absolute value |dZ/dt| of the amount of change of the total load (Z) is equal to or lower than a threshold value (Beta); a means for determining the calculated data as the presence of input when the absolute value |Z| of the total load is equal to or larger than a threshold value (Gamma); and a means for removing a predetermined number of pieces of data from the first and from the last, among the calculated data continuously obtained from the calculation means.
