    Abstract: A camera device is provided, which is switchable between an unfolded state and a folded state. The camera device includes a first lens module and a second lens module. The first and second lens modules are rotatably connected and respectively have a first optical lens and a second optical lens. When the camera device is in the unfolded state, the first and second optical lenses face a first direction. When the camera device is switched from the unfolded state to the folded state, the second optical lens module is rotated from a first position to a second position with respect to the first optical lens module, and the second optical lens faces a second direction, wherein the first direction is opposite to the second direction.

    Abstract: An optical touch screen includes a display panel, a first camera module, a second camera module, and a controller. The first camera module includes a first emitting unit and a first receiving unit. The first emitting unit is used for emitting a first light beam toward the surface of the display panel. The first receiving unit is used for capturing an image on the display panel. The second camera module includes a second emitting unit and a second receiving unit. The second emitting unit is used for emitting a second light beam toward the surface of the display panel. The second receiving unit is used for capturing another image on the display panel. The controller calculates a relative horizontal position of the object with the display panel, and determines whether a distance between the object and the display panel is located in a touch area or a hover area.

    Abstract: A non-contact elevator control system having a control panel with multiple buttons, an image processor, a first and a second camera module, wherein the first and second camera modules are arranged at two adjacent corners of the control panel, is disclosed. When an object enters a detection range, the image processor obtains a first imaging position of the object based on a first image taken by the first camera module and a second imaging position of the object based on a second image taken by the second camera module. The image processor calculates the corresponding position of the object in the control panel according to the first and the second imaging positions, and the relative position information of the first and second imaging positions with respect to the first and second camera modules. The image processor triggers a corresponding button in the control panel based on the position.

    Abstract: An optical touch system includes a screen, an image-erasing device, an image-sensing module, a processing unit, and an image processor. The image-erasing device includes a body and reflection portions on the body. The image-erasing device is detachably contacted with the screen. The image-sensing module includes a light source emitting a light beam to the reflection portions to respectively generate a reflected light beam, and an image sensor detecting the reflected light beams. The processing unit obtains positions on the screen respectively corresponding to the reflection portions according to the reflected light beams, and defines position information of an erasing region according to the positions on the screen. The image processor outputs a display image to be displayed on the screen, and erases data of the display image corresponding to the erasing region according to the position information.
