Abstract
An interactive pointing device capable of switching capture ranges includes an image capturing element and a processing unit. The image capturing element operates in a first capture range or a second capture range. The image capturing element is used for capturing a light source, and outputting an image signal. When a distance from the interactive pointing device to the light source is smaller than a reference value, the processing unit controls the image capturing element to detect the light source with the first capture range, and the processing unit converts the image signal into a first coordinate data. When the distance is greater than the reference value, the processing unit controls the image capturing element to detect the light source with the second capture range, and the processing unit converts the image signal into a second coordinate data.
