Input device and electronic apparatus using the same

摘要

An input device includes an input-sensing unit that contains a capacitive input sensor and a sensitivity-sensing unit that contains a capacitive sensitivity sensor. The input-sensing unit senses position information obtained by touch operation of an operation body to the capacitive input sensor. The sensitivity-sensing unit senses sensitivity information obtained by touch operation of the operation body to the capacitive sensitivity sensor. The input device includes a control unit determining whether or not the output level of the position information from the input-sensing unit is adjusted based on the sensitivity information sensed by the sensitivity-sensing unit and a sensitivity-adjusting unit that adjusts an output level of the position information from the input-sensing unit based on a result of the determination of the control unit. The control unit controls the sensitivity-adjusting unit to adjust the output level of the position information received from the input-sensing unit.

1. An input device comprising:
an input-sensing unit that contains a capacitive input sensor, the input-sensing unit sensing position information obtained by touch operation of an operation body to the capacitive input sensor and outputting the position information; a sensitivity-sensing unit that contains a capacitive sensitivity sensor, the sensitivity-sensing unit sensing sensitivity information obtained by the touch operation of the operation body to the capacitive sensitivity sensor and outputting the sensitivity information, wherein the position information is independent from the sensitivity information; a control unit that receives the position information from the input-sensing unit and receives the sensitivity information from the sensitivity-sensing unit, the control unit determining whether or not an amplitude of the output of the position information from the input-sensing unit is adjusted based on the sensitivity information sensed by the sensitivity-sensing unit, and when the control unit determines that the amplitude of the output of the position information is to be adjusted based on the sensitivity information sensed by the sensitivity-sensing unit, the control unit generates adjustment data and transmits the adjustment data to a sensitivity adjusting unit; and the sensitivity-adjusting unit that adjusts the amplitude of the output of the position information from the input-sensing unit based on the adjustment data received from the control unit, wherein the control unit controls the sensitivity-adjusting unit to adjust the amplitude of the output of the position information received from the input-sensing unit, and wherein the control unit generates adjustment information for increasing the amplitude of the output of the position information from the input-sensing unit if the sensitivity information sensed by the sensitivity-sensing unit is compared with a predetermined threshold value when the control unit determines that the sensitivity information is smaller than the predetermined threshold value.
