Abstract: A detection device includes: a sensor having a detection region; electrodes arrayed in a first direction and a second direction in the detection region; a detection circuit configured to generate detection values of the electrodes based on detection signals from the electrodes; and a processing circuit configured to generate spatial coordinates indicating a position of an object to be detected on or above the detection region. The spatial coordinates include first data indicating a position in the first direction, second data indicating a position in the second direction, and third data indicating a position in a third direction. The processing circuit acquires the first to third data based on the detection values and generates the spatial coordinates when at least one of the detection values is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold.
