The image capturing device captures an image of an area to include the light-emitting portion with an unadjusted capturing angle and focal distance and can adjusts the capturing angle and the focal distance to obtain an adjusted image. The light-emitting portion is to be located at a preset coordinated position in the target image before adjustments are made. The image capturing device captures images including a speaker at the microphone, applying an adjusting capturing angle and an adjusted focal distance. A positioning system is also disclosed.
