Abstract:
1. An interactive pointing device capable of switching capture ranges, comprising: an image capturing element, capable of operating with a first capture range or a second capture range, for capturing an optical signal from an external light source, and outputting an image signal from the optical signal based on the first capture range or the second capture range; and a processing unit, for responding to a switching signal, wherein when the switching signal is in a first mode, the processing unit controls the image capturing element to capture the optical signal with the first capture range, and the processing unit calculates a first coordinate data based on the image signal from the optical signal, and when the switching signal is in a second mode, the processing unit controls the image capturing element to capture the optical signal with the second capture range, and the processing unit calculates a second coordinate data based on the image signal from the optical signal, wherein the first capture range is corresponding to a first sensing angle, and the second capture range is corresponding to a second sensing angle.
