Abstract
A coordinate input device and a touch panel device determine a correction value with a plurality of output values obtained from a plurality of sensors arranged in a touch panel based on the output value of a 1st peak sensor that outputs the largest output value, the output value of a 2nd peak sensor having the second largest output value, the output value of a 3rd peak sensor having the third largest output value, and the output value of a 4th peak sensor having the fourth largest output value.
