1. An input detection device that detects an input position of an inputter on a display panel, the input detection device comprising:
an input circuit that inputs a drive signal to an electrode group including a number of electrodes that are arranged adjacent to each other among a plurality of electrodes arranged in parallel on the display panel; and
a detection circuit that detects the input position based on a detection signal corresponding to the drive signal input to the electrode group, wherein
the input circuit inputs a first drive signal to a first electrode group including a plurality of electrodes at a first timing and inputs, at a second timing subsequent to the first timing, a second drive signal to a second electrode group including a number of the electrodes included in the first electrode group and at least one electrode positioned adjacent to the first electrode group, and
the detection circuit detects the input position based on a first detection signal corresponding to the first drive signal and a second detection signal corresponding to the second drive signal.
