The projection apparatus includes a projection module, a decoder, and an optical device. The projection module is used for alternately projecting first projected images and second projected images according to a three-dimensional video signal. The decoder is coupled to the projection module, and used for receiving and decoding the three-dimensional video signal to generate and wirelessly transmit a status signal. The optical device is used for receiving a frame switching control signal outputted from the projection module, used for receiving the status signal from the decoder, and use for receiving the first projected images and the second projected images in an image receiving status.

Abstract: A decoder, a projection device, and an image processing method are provided. The decoder has a decoding circuit and a buffer coupled to the decoding circuit. The decoding circuit receives a three-dimensional video signal and a control signal and decodes the three-dimensional video signal to generate first image data and second image data. The buffer temporarily stores at least one of the first image data and the second image data. The decoding circuit adjusts an output time difference between outputting the first image data and outputting the second image data according to the control signal.

Abstract: A speaker system and a method for optimizing an output of a speaker thereof are provided. The speaker system includes a speaker, an automatic gain control amplifier, a volume adjustment unit, a controller, and an indication unit. The function of the automatic gain control amplifier may be intelligently optimized by the controller, so that the controller may remind the user that the automatic gain control amplifier is operated in a reduced dynamic range through the indication unit in case that the volume adjustment unit receives an input sound frequency signal of a very high intensity. With the help of the indication unit, the user may easily find an optimal operation spot of the automatic gain control amplifier, and the speaker system may generate enough sound with a good dynamic range.

Abstract: The dimensions of a viewing screen are altered to fit the aspect ratio of video being displayed on the viewing screen. A viewing screen includes screen covers which may be displaced horizontally along the viewing screen. If a different aspect ratio video is being displayed, the screen covers are moved horizontally to increase or decrease the viewing area of the viewing screen. The video is then optically resized and shifted to fit the height or width of the screen.

Abstract: A method of operating a video device includes determining an operating temperature, determining if the operating temperature is above normal operating temperature for the video projector, and setting the video projector in economy mode if the operating temperature is above the normal operating temperature.

Abstract: A projection screen is disclosed, which includes an upper housing, an upper roller, a reflecting curtain, a lower housing, a lower roller, a lower mask and a positioning assembly. The upper roller is pivoted in the upper housing. The reflecting curtain is wound on the upper roller and has a reflecting surface to form a projection area. The lower housing is fixed at a free end of the reflecting curtain. The lower roller is pivoted in the lower housing. The lower mask is wound on the lower roller. The positioning assembly detachably connects a free end of the lower mask to the reflecting curtain, so that the lower mask covers a portion of the reflecting surface of the reflecting curtain to define the boundary of the projection area.

Abstract: Frame expanding glasses adapted to be used with a display apparatus for making a user observe an expanding frame are provided. The frame expanding glasses include a left eye optical module and a right eye optical module. The left eye optical module is disposed between a left eye frame and the left eye of the user. The left eye optical module includes a left eye prism and a first frame selector. The right eye optical module is disposed between a right eye frame and the right eye of the user. The right eye optical module includes a right eye prism and a second frame selector. A frame expanding visual system using the frame expanding glasses is also provided.

Abstract: Systems and methods which can shift video to the edge of the display screen. The user can electrically and mechanically roll up or down the projection screen to fit the opposite edge. Further, the electrically shifted position can be memorized in memory, which will be easily recalled during future use. Also, to avoid displaying visible noise near the top edge of the video, the video may be shifted to avoid such noise being visible. The shifted position may be stored in memory to be recalled for future use.

Abstract: A video system includes a video projector located in a housing a display screen disposed adjacent to the housing, wherein the display screen is capable of being tilted to expose the video projector, logic for generating a test image to display on the tilted display screen in order to calibrate the video projector, logic for projecting the test image onto the tilted display screen; and logic for calibrating the video projector using the test image. The test image is altered to fit the tilted display screen.

Abstract: A video projector generates a black screen. Further, the video projector reduces the brightness of the light source which reduces the power level of the video projection system. Since the light source's power is reduced, less heat is generated by the video projector and the video projector's cooling fan may be slowed down. As a result, the video projector produces less noise.
