  • Publication number: 20190370968
    Abstract: An image capturing device used to capture an image of an object is provided. The image capturing device includes a camera, a first light source and a controller. The first light source is disposed adjacent to the camera. The controller is electrically connected to the camera and the first light source and is configured to: control the camera to capture a first picture of the object under the condition that the first light source does not emit any light; control the camera to captures a second picture of the object under the condition that the first light source emits a light; subtract the first picture from the second picture to filter off the background brightness of the second picture to obtain a first filtered picture; and analyze the first filtered picture to obtain a probability of the object matching a certain state.

  • Patent number: 10444863
    Abstract: A virtual reality device, including a first sensor, a second sensor, a processor, and a display screen, is provided. The first sensor senses a first rotation-amplitude corresponding to the virtual reality device, and outputs a first sensing signal corresponding to the first rotation-amplitude. The second sensor senses a second rotation-amplitude corresponding to the user's eyes, and outputs a second sensing signal corresponding to the second rotation-amplitude. The processor generates a panoramic image, and obtains an initial display picture. The display screen displays the initial display picture. The processor further outputs a first display picture according to the first sensing signal and the second sensing signal, and the display screen displays the first display picture.

  • Patent number: 10341557
    Abstract: An image processing apparatus including a wide-angle camera, an auxiliary camera, and a controller is provided. The wide-angle camera has a first Field Of View (FOV), and captures a first image of a first area of a scene. The auxiliary camera has a second FOV which is narrower than the first FOV, and captures a second image of a second area of the scene. In particular, the wide-angle camera and the auxiliary camera are disposed on the same surface of the image processing apparatus, and synchronized to capture the first image and the second image, respectively. The controller determines a portion of the first image, which corresponds to the second area of the scene, and superimposes the second image on the portion of the first image to generate an enhanced image.

  • Publication number: 20190130869
    Abstract: A head-mounted display device including a camera, a controller, and a display system is provided. The camera captures an original image of the surrounding environment. The controller determines an area of a predetermined color in the original image, and increases at least one of the saturation level and the intensity level of the original image in the area to generate a color-difference enhanced image. The display system displays the color-difference enhanced image.

  • Patent number: 10277789
    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.

  • Patent number: 10236143
    Abstract: An operation mechanism is provided, including a fixed ring and a rotating assembly, wherein the rotating assembly is rotatably connected to the fixed ring. The rotating assembly includes a rotating ring and a movable portion. The rotating ring connects to the fixed ring. The rotating ring and the movable portion are fixed to each other. The movable portion is disposed on a surface of the fixed ring and configured to contact a circuit board disposed on the surface. When the rotating assembly is rotated from a first position to a second position relative to the fixed ring, the movable portion moves from a first contact position to a second contact position relative to the circuit board.
