Claim 7:
8. A touch operation detection method that, in a touch panel provided with a plurality of drive lines arranged in parallel, and a plurality of sense lines arranged in parallel and intersecting the plurality of drive lines, inputs an input signal with respect to the plurality of drive lines in parallel and drives the plurality of drive lines, detects an output signal from the plurality of sense lines in parallel, and detects a touch operation made with respect to the touch panel based on a linear element sequence corresponding to a magnitude of a capacitance at each intersection between the plurality of drive lines and the plurality of sense lines calculated based on a matrix operation of an input sequence corresponding to a magnitude of the input signal and an output sequence corresponding to a magnitude of the output signal, the method causing one or more processors to execute:
inputting the input signal with respect to the plurality of drive lines;
detecting the output signal that is output from the plurality of sense lines;
grouping the plurality of drive lines into a plurality of groups each having a set grouped number of adjacent drive lines;
detecting a touch operation made with respect to the touch panel based on the linear element sequence calculated by a matrix operation of the input sequence and the output sequence; and
inputting the input signal having the same pattern to each of the grouped number of drive lines that have been grouped.
