The power consumption of an apparatus including a touch panel is reduced. In a touch panel control device (1) including a sensor drive section (22) and a liquid crystal drive controller (10), the sensor drive section (22) makes a detection sensitivity during a pause period lower than a detection sensitivity during an update period, the pause period being a period in which the liquid crystal drive controller (10) does not update the image that is displayed on a liquid crystal display panel (40), the update period being a period in which the liquid crystal drive controller (10) updates the image that is displayed on the liquid crystal display panel (40).
