摘要： An interactive pointing device capable of switching capture ranges includes an image capturing element and a processing unit. The image capturing element is used for capturing an optical signal, and outputting an image signal. The processing unit is used for determining a switching signal, and responsible for processing and analyzing the image signal. Through the determination about the switching signal and the coordinate conversion of the image signal by an arithmetic unit, the interactive pointing device capable of switching capture ranges is enabled to be operable in hosts with different resolutions.

摘要： A control device for an image display includes at least two reference points, a modulation unit and a remote controller. The modulation unit modulates the light of a predetermined spectrum generated by the reference points with a brightness variation cycle. The modulation unit controls the reference points to emit the light with a first brightness within a first period of the brightness variation cycle and to emit the light with a second brightness within a second period of the brightness variation cycle, wherein the first brightness and the second brightness are not zero gray level. The remote controller captures the light of the predetermined spectrum with a sampling cycle and demodulates an image variation of the reference points with respect to the remote controller. The present invention further provides a control method for an image display.
