In the era of LED display screen, video processor not only carries a lot of work such as image processing and analysis, coding and decoding compression, but also embeds a large number of intelligent analysis algorithms to analyze massive data. Due to the influence of regional weather, the outdoor LED display screen is different from night and day, and the sunny day is different from rainy day. How can led display perfect picture with the change of weather; This requires the video processor to have more excellent image quality improvement ability, with advanced image scaling processing algorithm, to ensure that the video image after scaling processing, the maximum degree of image clarity and gray level. In addition, the video processor is also required to have rich image adjustment options and adjustment effects to process image brightness, contrast and gray to ensure soft and clear screen output. The function of the LED video processor is to convert the image signal from the outside into the signal that the LED display can accept. The advantages and disadvantages of LED video processor directly affect the display effect of LED display screen.
How does LED video processor complete the perfect display of LED display? It mainly includes the following points:
1、 Multi image processing, in many special scenes, a display screen needs to display multiple pictures with the same or different signals. The video processor with multi image processing function can flexibly meet such display requirements.
2. Picture zooming, the display mode of LED display screen is point-to-point, which determines that the LED display can only display the picture consistent with its own physical resolution. LED video processor can zoom the image, output the picture in any size, and map the whole desktop to the LED screen. [LED display manufacturer] signal conversion and switching, video processing equipment can complete the format conversion between many signals. Another important function of video processor is to manage all kinds of signals when there are multi-channel signals, and switch between them flexibly.
4. Large screen splicing, the point spacing of LED display screen is becoming smaller and smaller, and the overall size is becoming more and more huge, which makes the physical resolution of LED screen become very large. LED video processor has splicing function and can drive large resolution screen, which is a very cost-effective driving mode.
5. Image quality is improved, because the pixel spacing of LED display screen is much larger than that of other flat panel display media, so there are strict requirements for image processing technology, especially image enhancement technology. High quality LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as de interlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the image quality.
