摘要 |
A sensing device includes: a plurality of sensors that are arrayed on a screen and that generate first detection signals each having a level corresponding to a touch state of an object on the screen or a distance between the object and the screen; a read unit that reads the first detection signals from the plurality of sensors at predetermined periods; a binarization unit that compares a level of each of the first detection signals read by the read unit with a threshold value and generates a second detection signal that is binarized; a determination unit that determines whether or not the object touches the screen on the basis of each second detection signal; a detection unit that detects a touch position of the object on the screen on the basis of each second detection signal; and a control unit that controls the read unit such that the predetermined period becomes a first period when the determination unit determines that there is no touch and that controls the read unit such that the predetermined period becomes a second period shorter than the first period when the determination unit determines that there is a touch. |
