Abstract: A three-dimensional image apparatus and an operation method thereof are provided. The three-dimensional image apparatus includes a projection unit, a photographic apparatus, a display module and a control unit. In a scan mode, the control unit controls the projection unit to project a structure-light pattern onto an object to be captured in different angles relatively to the object and controls the photographic apparatus to capture a plurality of composition images corresponding to different angles of the object. The composition images are converted into a three-dimensional image in a three dimensional image format through an image conversion module, and the three-dimensional-format image may display a displaying image of the object in a specific viewing angle through the display module. The projection unit and the photographic apparatus are located at a same side of the three-dimensional image apparatus.

Abstract: An input/output device and human-machine interaction system and method thereof are provided. The input/output device includes a projection module, an image capturing module and a processing module. The projection module is capable of receiving an image provided by a mobile computing device and projecting the image onto a surface. The image capturing module is capable of capturing a user's operation action on a projected image on the surface to thereby provide operation information. The processing module is electrically connected with the image capturing module for receiving and processing the operation information to thereby generate an operation command to correspondingly control the mobile computing device.

Abstract: A projector assembly includes a projector casing and an auxiliary device. The projector casing is formed with a mating aperture, and has a first light source for emitting light beams defining an optical path of the projector assembly. The auxiliary device includes a mating part inserted detachably into the mating aperture in the projector casing, a second light source disposed in the mating part for emitting light beams, and a light-beam guiding module disposed in the mating part in front of the second light source so that the light beams emitted from the second light source are guided into the optical path via the light-beam guiding module, thereby enhancing illumination of the optical path of the projector assembly.

Abstract: A backlight module includes a light box, at least one light guide tube, and at least one light source. The light box has a light exit side. The light guide tube has a plurality of microstructures which are spaced apart along a length of the light guide tube. The light guide tube and the microstructures are disposed in the light box in a particular arrangement so that the microstructures are placed substantially in a matrix array within the light box. The light source is disposed adjacent to the light guide tube, and is operable so as to emit a light beam to the light guide tube. The microstructures disperse the light beam from the light guide tube.

Abstract: An interrupt processing method and apparatus particularly well-suited for use in an interrupt controller of a multiprocessor system or device. Each of the interrupt requests has at least one destination processor associated therewith for servicing the interrupt request. An interrupt controller in accordance with the present invention applies latched interrupt requests to a priority compare tree which serves to prioritize received interrupt requests. A number of higher priority requests, including the highest priority request, are supplied to a destination selection circuit which includes an interrupt dispatcher which determines a processor to which the first priority interrupt request will be dispatched. Similar determinations are made for the remaining identified interrupt requests, but with the corresponding destination register contents masked to prevent processors already selected to receive a higher priority interrupt from being considered for a lower priority interrupt.

Abstract: An expandable ROM module adapted for use with an existing ROM interface having a predetermined number of address lines to provide an expanded memory array of variable size. The expanded memory is divided into a plurality (T) of pages and a temporary storage device is provided to store page address data. The temporary storage device includes a T-bit page selection register, which receives address input from the ROM interface, and a mapping array, which has T entries, to direct address inputs to each page. Page address data are stored in the temporary storage device via a convert-read-to-write method, which utilizes read interface and read cycle to perform write operations. Several convert-read-to-write methods can be provided depending on the number of addresses that need to be reserved and the complexity of circuitry and programming that will be involved. Examples of the convert-read-to-write methods include: direct, direct but segmented, indirect and segmented, multiple-indirect and segmented.
