Problems solved by technology
Therefore, the operating distance of the existing technology is L~2L. If the operating distance is less than L or greater than 2L, the system will not respond correctly
[0005] Regarding the aforementioned limited operating distance or operating range, when the maximum operating distance is exceeded, the light point image will be smaller than the minimum size requirement and cannot be recognized
When the operating distance is less than the minimum, the spot image will be larger than the maximum limit and cannot be recognized
If the spot image is enlarged in order to increase the maximum operating distance, the shortest operating distance of the spot image will be limited; conversely, if the spot image is reduced in order to expand the minimum operating distance, the longest operating distance of the spot image will be limited distance

The invention provides an optical remote-control system and a light source control method used for the optical remote-control system, the optical remote-control system comprises a light source containing a plurality of luminescence units for emitting at least a light; an image sensor for receiving the light for imaging; and a processor used for determining the number or the position of the luminescence units which are turned on according to the imaging area by light.
Description
technical field [0001] The invention relates to an optical remote control system and a light source control method used therein, in particular to an optical remote control system capable of modulating a light source for orientation and a light source control method thereof. Background technique [0002] Recently, many electronic interactive game systems provide users with joysticks or remote controllers to operate more motion-sensing electronic games, such as games such as car driving and golfing. Such joysticks may include gyroscopes, accelerometers or image sensors. At present, the image sensor in the joystick can be used to control the movement of the cursor on the screen, or to click a certain image on the screen to directly perform selection or other operations. [0003] Figure 1A Mark the schematic diagram of using the joystick in the existing electronic interactive game system. The joystick 11 is oriented according to the image captured by the image sensor 111, tha...
