Patent Images
1. An input device comprising:
- an image processing module to extract a motion vector with respect to an external image;
a motion sensing module to sense motion of a housing of the input device and to estimate a posture of the housing;
a control module to correct the motion vector using the estimated posture, if motion of the housing is sensed; and
a transmission module to transmit the corrected motion vector.
