PURPOSE: An optical joystick module is provided to block the inflow of an external light transmitted to an image sensor and improve the operating performance. CONSTITUTION: A subject contracts with an optical joystick module, and the optical joystick module is coupled with a cover plate comprising a non-transmission unit and a transmission unit. A holder(20) includes an acceptance space at its inside, and an illumination member(30) irradiates the light toward the subject by being installed at an external plane of the holder. An image unit forms a light source in image, and an image sensor receives the light source through the image unit and calculates the light source in variation value. |
