TOUCH PANEL

Provided is a touch panel which completes touch detection within a specified time even when the maximum number of touch points is set to be large. A control portion assigns priorities for being given a high coordinate precision to the respective touch points based on the state of the touch points. The control portion selects coordinate calculation algorithms having coordinate precisions corresponding to the priorities of the respective touch points from among a plurality of coordinate calculation algorithms, and calculates required calculation time for calculating coordinates of all the touch points. The control portion determines the priorities so that the calculated required calculation time is equal to or shorter than a specified time. The control portion selects coordinate calculation algorithms corresponding to the priorities and calculates the coordinates of the respective touch points.
