CURSOR CONTROL DEVICE AND SYSTEM
First Claim
1. A cursor control device, comprising:
- an image sensor configured to capture a plurality of image frames;
at least one button configured to output a trigger signal while being pressed;
a processing unit configured to calculate at least one of a displacement and a cursor coordinate according to the image frames and output a control signal according to the trigger signal;
a selection unit configured to select one of at least two different cursor lock periods; and
a transmitter configured to output the control signal and at least one of the displacement and the cursor coordinate, wherein the processing unit controls the transmitter to output zero displacement or not to update the cursor coordinate within the cursor lock period selected after receiving the trigger signal.

Abstract
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.
