Abstract: According to an aspect, a detection apparatus includes: a detection electrode block including detection electrodes arranged in a first direction; a detection circuit configured to be coupled to the detection electrodes to detect detection signals; and a coupling circuit. The coupling circuit has a first mode of coupling the detection electrodes to the detection circuit by r coupling patterns corresponding to a first row to an r-th row of a Walsh Hadamard matrix in a first period, and a second mode of coupling the detection electrodes to the detection circuit by n coupling patterns (n>r) corresponding to the first row to an n-th row of the Hadamard matrix in a second period longer than the first period. The coupling circuit does not couple the detection electrodes to the detection circuit by a coupling pattern corresponding to an (r+1)-th row of the Hadamard matrix in the first mode.
