Abstract
A light pointing device employed in an input apparatus comprises a signal receiving interface and a light emitting component. The signal receiving interface is used to receive a system signal from the input apparatus. The light emitting component can generate a flashing light source whose intermittence cycle is synchronized with the reference clock cycle of the system signal. Furthermore, the ratio of the intermittence cycle of the flashing light source to the reference clock cycle of the system signal is a natural number.
