A computer-readable storage medium storing an information processing program executed by a computer of an information processing apparatus that obtains, from an input device including an acceleration sensor for detecting acceleration and an angular velocity sensor for detecting an angular velocity, acceleration data indicative of the acceleration and angular velocity data indicative of the angular velocity, is provided. The information processing program causes the computer to perform data obtaining and acceleration correction. The data obtaining repeatedly obtains the acceleration data and the angular velocity data. The acceleration correction corrects, based on the magnitude of the angular velocity indicated by the angular velocity data, the acceleration indicated by the acceleration data.
