There are provided an apparatus and a method of controlling capacitance detection, and a touchscreen apparatus. The apparatus includes: a driving circuit unit providing driving signals including a preset number of driving pulses to a plurality of respective driving electrodes of a panel unit; a detecting circuit unit removing electrical noise from a first voltage corresponding to a capacitance change in the panel unit when the electrical noise is included in the first voltage; and a controlling unit controlling the driving circuit unit to generate an additional driving pulse when the electrical noise is included in the first voltage.
