Sensing device and driving method of sensing device

A driving method of a sensing device, the sensing device including a plurality of sensing electrodes arranged in a row direction and a column direction, a sensing circuit including a plurality of read-out circuits respectively connected to the plurality of sensing electrodes and a control circuit for controlling the plurality of read-out circuits, and an arithmetic circuit that arithmetically is configured to process a sensing signal output from the sensing circuit;

• the plurality of sensing electrodes and the plurality of read-out circuits are connected one-to-one via wiring;
• and the sensing circuit is configured to store a driving table that stores multiple sampling frequencies different from each other, the method comprising:
• reading out the multiple sampling frequencies different from each other;
• driving simultaneously the plurality of read-out circuits at the multiple sampling frequencies different from each other;
• generating a plurality of output signals obtained by the driving;
• performing arithmetic processing on the plurality of output signals read out using the multiple sampling frequencies different from each other;
• and
• calculating an amount of noise.
