Abstract
To provide an information processing apparatus and information processing method capable of correcting a contact or proximity position to be closer to a user-intended contact or proximity position with high accuracy. It includes a calculation unit 163 that 3-value processes the proximity value to detect a first region and a second region depending on the 3-value processed proximity value and then calculates positions of respective centroids of the first region and the second region to calculate a direction of a straight line connecting the respective centroids, a calculation unit 162 calculating a contact or proximity position between the operation object and the surface of the display unit based on the proximity value, and a calculation unit 165 calculating a pointed position different from the contact or proximity position based on the contact or proximity position and the direction of the straight line connecting the first centroid and the second centroid.
