COORDINATE DETECTING DEVICE
First Claim
1. A coordinate detecting device comprising:
- a plurality of first electrodes arranged in a first direction and a plurality of second electrodes arranged in a second direction different from the first direction;
a detecting unit configured to scan the plurality of first electrodes and the plurality of second electrodes, thereby detecting sensor output values of the first electrodes and sensor output values of the second electrodes; and
an arithmetic processing unit configured to perform an arithmetic process on the basis of the sensor output values detected by the detecting unit,wherein, when there are a plurality of peak regions in which the sensor output values of both the first electrodes and the second electrodes are equal to or greater than a first threshold value, the detecting unit detects the sensor output values at intersection points between the first electrodes and the second electrodes in the peak regions, andthe arithmetic processing unit calculates the coordinates of a detection target on the basis of the sensor output values at the intersection points between the first electrodes and the second electrodes in the peak regions and the coordinates of the first and second electrodes in the peak regions.

Abstract
A coordinate detecting device includes a plurality of first and second electrodes, a detecting unit for scanning the first and second electrodes to detect sensor output values of the first and second electrodes, and an arithmetic processing unit for performing an arithmetic process on the basis of the detected sensor output values. When there are a plurality of peak regions in which the sensor output values of both the first and second electrodes are equal to or greater than a first threshold value, the detecting unit detects the sensor output values at intersection points between the first and second electrodes in the peak regions. The arithmetic processing unit calculates the coordinates of a detection target on the basis of the sensor output values at the intersection points between the first and second electrodes in the peak regions and the coordinates of the first and second electrodes in the peak regions.
