Abstract: An oral cavity scanning device is provided in the invention. The oral cavity scanning device includes an image capturing unit, an IMU circuit and a processing unit. The image capturing unit obtains a first image and a second image. The IMU circuit obtains IMU information corresponding to the first image and the second image. The processing unit obtains a distance value between the first image and the second image. The processing unit uses a contour algorithm to obtain a first contour and a second contour. The processing unit obtains first sampling points according to the first contour and second sampling points according to the second contour. The processing unit uses a feature algorithm to find relative feature points between the first sampling points and the second sampling points. The processing unit uses a depth information algorithm to obtain the depth information of each feature point.

Abstract: An inspection device is provided, including a base, a circuit assembly, an electrocardiogram sensor, a diaphragm, an annular member, and a positioning member. The base has a top surface, a bottom surface, a guiding portion, an opening, and an accommodating space. The guiding portion is formed on the top surface, the opening is formed on the bottom surface, and the accommodating space is formed between the top surface and the bottom surface. The circuit assembly is disposed in the accommodating space, and has a first contact and a second contact. The electrocardiogram sensor is disposed on the bottom surface and electrically connected to the circuit assembly. The diaphragm covers the opening. The annular member is rotatably connected to the base and has a guiding member. The guiding member is slidably connected to the guiding portion. The positioning member is affixed to the annular member and has a contacting portion.

Abstract: A method of automatically triggering scanning operation through specific motion includes steps as follows. A specific motion trajectory of a scanning device is sensed to determine whether the scanning device is moved along a predetermined path. If so, an image sensor of the scanning device is switched on. A determination is made as to whether the scanning device is moved down to a lower position. If so, the image sensor of the scanning device is switched off.

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.

Abstract: An electronic device able to show light graphic includes a housing, plural light-transmissive plates stacked inside the housing, plural light sources disposed inside the housing, and a control unit disposed inside the housing. Each of the light-transmissive plates includes a light-incident surface, a light output surface and an optical pattern formed on the light output surface thereof. Projection zones of the light output surfaces to the light-transmissive region are overlapped. The light sources are respectively arranged for emitting lights towards the light-incident surfaces. The control unit is electrically connected to the light sources for controlling at least one of the light sources to emit lights towards the light-incident surface of the corresponding light-transmissive plate, so that the lights form a light graphic by the optical pattern of the corresponding light-transmissive plate, and the light graphic is shown on a light-transmissive region.
