A data processing method and device for a Light emitting diode (LED) Television (TV), and an LED TV are disclosed, the data processing device includes: a signal processing chip configured to perform mode conversion on a received TV signal so as to obtain a first video signal of a preset mode; and a video processing chip connected to the signal processing chip and configured to perform clock synchronization processing on the first video signal so as to obtain a second video signal and output the second video signal to an LED display. The problem in the prior art that an LED TV can only display a TV signal of a single mode is solved, thereby achieving the effect that the LED TV can display videos of various modes and various formats.

Data processing method and device for LED televison, and LED television

A method and device for processing a video image are provided. The method comprises: receiving an original video image; adjusting a signal clock frequency of the original video image to acquire a processed video image; after a command signal input by a user is received, capturing the processed video image according to a preset size to acquire a video image corresponding to a display window of the preset size; and encoding the video image corresponding to the display window of the preset size to acquire an encoded video image. According to the method and device for processing the video image disclosed by the disclosure, new line, field and blanking synchronization signals are acquired through adjusting the clock frequency of an input image, and then, the corresponding capturing operation and outputting operation are performed according to the image display requirements of the user, so that the effect that video images with any resolution are reliably and stably displayed in the best display area range is realized.

Method and device for processing video image

The present invention discloses a method for and a system for reducing the dynamic false contour in the image of an alternating current plasma display. The method includes the following steps: dividing each frame image into multiple subfields; accounting the number and the probability of the dynamic false contour appeared in each frame image; based on the result of the accounting, carrying out an optimized coding for the pixel data of each frame image, and if there is an error generated by the optimized coding, diffusing the error generated by the optimized coding into neighboring pixels.
