Abstract: An apparatus for image reproduction and a method therefor are provided. The apparatus includes a processing module and a logic circuit. The processing module outputs a data signal. The logic circuit is for selectively processing a single image of the data signal and a group of images of the data signal for displaying. When the apparatus is in a synchronization mode, the logic circuit processes a data pattern of the data signal for determining a sequence of the data signal. When the apparatus is in a display mode, the logic circuit processes the group of images of the data signal according to the determined sequence. In an embodiment, the group of images indicates a three-dimensional (3-D) image for displaying by a 3-D panel.

Abstract: A portable device for transmitting a positioning information to a remote device is disclosed, which comprises: a positioning unit, for acquiring the positioning information; a timing unit, for calculating a first time interval and a second time interval; a calculating unit, coupled to the positioning unit and the timing unit, for calculating a speed parameter according to the first time interval and the distance of two positioning information acquired within the first time interval; and a transmission unit, coupled to the speed calculating unit and the timing unit, being defined to transmit the positioning information in every second time interval while the second time interval is change with respect to the speed parameter.
