Title:
CAPACITANCE DETECTION DEVICE, TOUCH PANEL, ELECTRONIC EQUIPMENT, PROGRAM, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/027044
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the erroneous detection of electrode capacitance changes and the like. A capacitance detection device (1) comprises: a voltage measurement unit (11) that measures first voltage values (V1) and/or second voltage values (V2) for a predetermined number of cycles; and a validity determination unit (12) that determines whether a voltage value measured when a capacitance or capacitance change is detected in an electrode (E) is valid or not on the basis of the first voltage values (V1) and/or second voltage values (V2) for the predetermined number of cycles.
