摘要： Disclosed is a method for automatically adjusting synchronization of sound and picture of TV. The method includes: obtaining a video, determining whether the video contains an adjustment video clip corresponding to a preset video database; obtaining audio information of the adjustment video clip and a time point corresponding to the audio information if the video contains the adjustment video clip corresponding to the preset video database; comparing the audio information of the adjustment video clip and the time point corresponding to the audio information with a standard video in the preset video database, and determining whether there is a synchronization delay between the sound and the picture; and synchronizing the sound and the picture of the video if there is the synchronization delay between the sound and the picture. A device for automatically adjusting synchronization of sound and picture of TV and a computer readable storage medium are further disclosed.

摘要： Provided is a video processing device that generates a display video signal to be supplied to a liquid crystal display having a liquid crystal that is driven by a frame inversion scheme and includes a control microcomputer and a video signal processor. The control microcomputer controls a data enable signal such that a display invalid section having a predetermined number of fields is set for an interlace video signal at a predetermined period based on a vertical synchronization signal included in the interlace video signal input from outside. The video signal processor generates the display video signal by setting the display invalid section for the interlace video signal based on the data enable signal and outputs the display video signal to the liquid crystal display.

摘要： A high-speed video system is disclosed that includes a moving image absorbing disk at an image plane. The disk has a pattern that passes and blocks image data. The disk is located between an event and an image sensor, or reflects an image to the image sensor. The disk is rotated at a speed that matches the desired reconstructed image frame rate. The image sensor frame data is processed using image reconstruction techniques, such as the D-AMP or TWIST algorithm, to recover a time sequence of reconstructed images. Additional images can be reconstructed for each image sensor frame if some spatial resolution is sacrificed. For continuous video, the disk speed is adjusted to the sensor frame rate. For burst mode, a single sensor image is acquired and a short image sequence is reconstructed. This image capture system works with a variety of radiations, including infrared, light, UV and X-rays.

摘要： Methods and devices for presenting a virtual reality image may include rendering at least one image frame received from an application for a virtual reality image for display on a display device. The methods and devices may include receiving a selection of one of a plurality of tear thresholds that define conditions for tearing in a displayed image. The methods and devices may include determining whether the rendered frame is received prior to the selected one of the plurality of tear thresholds, wherein the selected one of the plurality of tear thresholds occurs after a frame timing event that corresponds to a deadline for initiating display of a new frame. The methods and device may include communicating the rendered image frame to the display device for presentation on the display device when the rendered frame is received prior to the selected one of the plurality of tear thresholds.

摘要： A semiconductor device includes an adjusting circuit that transmits a control signal to a device to be controlled according to a transmission cycle synchronized with a reference clock. The device to be controlled has a first period during which the control signal is allowed to be supplied to the device to be controlled and a second period during which the supplying of the control signal to the device to be controlled is not preferable compared to that in the first period. The adjusting circuit is configured to, when a transmission timing of the control signal determined according to the transmission cycle is within the second period, adjust the transmission timing of the control signal so that the control signal will be transmitted in the first period.

摘要： A source driving device includes a locking module, a controlling module and a decoding module. The locking module executes a locking process selectively in a first band or a second band according to a band setting signal in order to lock a first clock signal synchronized with a first display signal. The controlling module is coupled to the locking module for comparing a control voltage with a reference voltage in the locking process and generates the band setting signal accordingly. The decoding module is coupled to the locking module for generating a decoded signal according to the first display signal and the first clock signal.

摘要： A received image displaying apparatus comprises: a wireless communication unit that wirelessly receives the frame images transmitted by the image transmitting apparatus with which the received image displaying apparatus has established a connection of wireless communication; and a displaying unit that displays the frame images, which were wirelessly received by the wireless communication unit, in an order in which the frame images were captured. At least one of the image transmitting apparatus and the received image displaying apparatus comprises: a reference sync signal generating unit that generates the reference sync signals; and a control unit that, if the wireless communication unit has received no reference sync signals for a certain time interval, controls the reference sync signal generating unit to generate reference sync signals and that further controls the wireless communication unit to wirelessly transmit the reference sync signals to the other apparatus included in the image transmitting/receiving system.

摘要： A system for at least substantially plesiochronously operating a receiver in communication with a plurality of cameras (e.g., at least two plesiochronously operational cameras) is described. In one or more implementations, the system includes a plurality of cameras. Each camera is configured to generate a signal for transmission via a communications link, and the signal comprises data packets encoded in a forward channel. The system also includes a receiver communicatively coupled to the plurality of cameras via the single-ended communications link. The receiver is configured to generate a synchronization data based upon at least one of the data packets. The receiver is also configured to modulate the signal to encode the synchronization data in a reverse channel so that the signal comprises the forward channel data and the reverse channel data simultaneously.
