摘要： An image displaying device includes a planar display panel and a light penetrating unit. The planar display panel displays a plane image. The planar display panel at least includes a first pixel group, a second pixel group and a third pixel group. The second pixel group is located between the first pixel group and the third pixel group. When vision passes through the light penetrating unit toward the planar display panel, the vision acquires a second distance of a second imaging position within the plane image relevant to the second pixel group relative to the planar display panel being greater than a first distance of a first imaging position within the plane image relevant to the first pixel group relative to the planar display panel and a third distance of a third imaging position within the plane image relevant to the third pixel group relative to the planar display panel.

摘要： The invention provides a three-dimensional object scanning device using structured lights and method using the same. A combination of specific monochrome light sources is used to construct the content of the structured lights to form a predetermined image, which is projected to the three-dimensional object such as an intraoral object. The combination of blue and green lights effectively eliminates reflective interference of the red or white environment within the intraoral space. Default patterns of the predetermined image are distinguished from one another by using well designed arrangement of color blocks so that specific coding information of location may be embedded and exploited.

摘要： A display system and a control method are provided. The display system includes a display device, an illumination device and a control circuit. The display device includes a display panel. The display panel is configured to display an image frame. The illumination device is movably disposed on the display device. The illumination device selectively projects light in a first direction or in a second direction different from the first direction. When the illumination device projects the light in the first direction, the control circuit generates a first control signal so as to control the illumination device to perform a first illumination mode. When the illumination device projects the light in the second direction, the control circuit generates a second control signal so as to control the illumination device to perform a second illumination mode different from the first illumination mode.

摘要： The present invention provides a display device. The display device includes a display module, a first mounting frame, one or more electromotive driving elements, and a control module. The display module is disposed on and spaced from a setting surface and has a display surface. The first mounting frame is spaced from the display module and is disposed on the setting surface. The electromotive driving elements are disposed on the first mounting frame and face the display module relatively. The control module controls display of the display surface based on a display signal, and controls each of the electromotive driving elements to selectively generate an attractive force and a repulsive force with respect to the display module based on an actuation signal, so as to change a distance of the display module from the first mounting frame, a setting angle of the display module with respect to the setting surface, or a combination thereof.

摘要： An image capturing device includes an image capturing unit, a light filter module, a light sensing unit, an infrared light source and a processing unit. The light filter module includes a first light filter and a second light filter. The first light filter filters an infrared and allows a visible light to pass. The second light filter filters a visible light and allows an infrared to pass. The light sensing unit senses an environmental light. When the processing unit determines that an intensity of the environmental light is higher than a threshold, the processing unit alternately switches the first light filter and the second light filter to a front of the image capturing unit, controls the image capturing unit to capture a visible light image through the first light filter, and controls the image capturing unit to capture an infrared image through the second light filter.

摘要： A projector includes an apparatus casing, a light source module, a flow generating device, a sensing module, and a power module. The light source module is disposed inside the apparatus casing and includes a light-emitting part and a lampshade surrounding the light-emitting part. The flow generating device can generate an air flow for dissipating heat by the light source module. The sensing module is disposed in the apparatus casing and includes a thermo-sensitive component disposed near the lampshade and located in a flowing path of the air flow. The power module is disposed in the apparatus casing and electrically connected to the light source module and the sensing module. The power module selectively stops powering the light source module according to an electric parameter of the thermo-sensitive component. Thereby, the invention protects the projector from being overheated by use of the thermo-sensitivity of the thermo-sensitive component.
