Coordinate input apparatus, method thereof, and storage medium

摘要

A coordinate input apparatus which detects a position pointed in a region surrounded by at least four sensor units, based on detection outputs from two sensor units corresponding to the pointed position out of the at least four sensor units stores, in a memory unit, correction values which are based on respective detection outputs of a plurality of combinations each of two sensor units out of the at least four sensor units for one position corresponding to the plurality of combinations, and calculates the pointed position based on the detection outputs from two sensor units corresponding to the pointed position, and the correction values stored in the memory unit.

1. A coordinate input apparatus which detects a position pointed in a region surrounded by at least four sensor units, based on detection outputs from two sensor units corresponding to the pointed position out of the at least four sensor units, an arithmetic control circuit of each sensor bar controls the two sensor units, the operation between the arithmetic control circuits is executed by master-slave, comprising: a input unit configured to input a plurality of directions corresponding to a common position detected by the at least four sensor units; a calculation unit configured to calculate correction data based on the plurality of directions corresponding to the common position detected by the at least four sensor units: and a storage unit configured to store the correction data in a memory unit, wherein the calculation unit is configured to calculate the pointed position based on the detection outputs from two sensor units corresponding to the pointed position, and on the correction data stored in the memory unit.
