An object sensing system includes an indication plane, a first image sensing unit, a plurality of light emitting units and a processing unit. The indication plane is used for an object to indicate a position. The first image sensing unit is disposed at a first corner of the indication plane. The light emitting units are disposed around the indication plane. Each of the light emitting units is corresponding to at least one of a plurality of operation times, at least one exposure time is set within each of the operation times, and each exposure time is corresponding to at least one of the light emitting units. The processing unit controls the light emitting units to emit light according to each exposure time correspondingly and controls the first image sensing unit to sense a first image relative to the indication plane within each operation time.
