A cursor control device includes an image sensor, at least one button, a processing unit, a selection unit and a transmitter. The image sensor captures a plurality of image frames. The at least one button outputs a trigger signal while being pressed. The processing unit calculates a displacement according to the image frames and outputs a control signal according to the trigger signal. The selection unit selects one of at least two different cursor lock periods. The transmitter outputs the control signal and the displacement, wherein the processing unit controls the transmitter to output zero displacement within the cursor lock period selected after receiving the trigger signal. The present disclosure further provides a cursor control system. |
