    摘要： A display system includes a controller and an image display panel. The controller includes a signal transmitter configured to output at least a vertical synchronization signal to a plurality of image-capturing apparatuses; and a synthesizer configured to provide synthesized image signals in units of lines obtained by synthesizing, in units of lines, image signals in units of lines output from the respective image-capturing apparatuses at a timing corresponding to a horizontal synchronization signal formed in a predetermined cycle based on an output timing of the vertical synchronization signal. The image display panel is configured to display sequentially, in units of lines, the synthesized image signals in units of lines.

    摘要： A server system with one or more processors and memory maintains a database for a plurality of root media items, where: a respective root media item is associated with a family tree that includes a genesis node and multiple leaf nodes; and the genesis node corresponds to the respective root media item and a respective leaf node of the multiple leaf nodes corresponds to a first modified media item that is a modified version of the respective root media item. The server system: receives at least a portion of modified metadata corresponding to a second modified media item that is a modified version of a media item corresponding to a respective node in the family tree; and, in response, appends, to the family tree, a new leaf node that is linked to the respective node, where the new leaf node corresponds to the second modified media item.

    摘要： A projector and an apparatus and method for driving an optical scanner are disclosed. A sensing signal processor receives a sensing signal that represents sensing of operation of the optical scanner and generates a horizontal scan signal corresponding to a horizontal frequency of the optical scanner on the basis of the received sensing signal. A driving signal generator generates at least one of a horizontal reference signal including line information that indicates the number of horizontal lines of a horizontal driving signal of the optical scanner, a reference clock signal and a scanner driving signal for driving the optical scanner on the basis of the generated horizontal scan signal.

    摘要： A method and an apparatus for data communication using digital image processing are provided. The method for transmitting data using digital image processing includes displaying a reference image including one or more frames having preset image quality and including clock data for data synchronization in each frame, determining whether a confirmation signal indicating that transmission of data is possible is received within a preset time, and displaying a corrected reference image having image quality differing from the preset image quality when the confirmation signal is not received within the preset time. Data may thus be transmitted without a separate transceiver supporting a certain communication scheme, and data synchronization between a receiving end and a sending end is thus possible to more conveniently transmit/receive data.

    摘要： A slicer level calculator including a signal detector, a moving average calculator, a sync-tip voltage sample circuit, a blanking voltage sample circuit, a slicer level calculator, and a rear-end processor is disclosed. The signal detector determines whether an input video signal satisfies a low signal to noise ratio (SNR) criterion. If so, the first signal detector further enables a low SNR control signal. The moving average calculator obtains a moving average voltage level of the input video signal. The sync-tip voltage sample circuit, the blanking voltage sample circuit and the slicer level calculator obtain a sync-tip voltage level, a blanking voltage level, and a slicer voltage level, respectively. The rear-end processor selectively executes low-pass filtering operation on the slicer voltage level in response to the low SNR control signal.
