LED video processors are also known as image processors, image converters, video controllers, image processor image converters, video format converters, independent video sources, and the like. The LED video processor is the key device for the birth, growth, and maturity of the image processor LED full-color display. The advantages and disadvantages of the LED video processor directly affect the display effect of the LED display. The combination of the LED video processor and the display greatly facilitates the wide application of the end-user and improves the depth of use of the LED display.
The full-color LED multi-screen video image processor is a full-color LED high-performance image processing controller launched by national high-tech enterprises. The device integrates years of experience in video image processing, HD signal processing, and display. The patented hardware design combines the special requirements of the full-color LED screen display to simultaneously receive and process a variety of different video graphics signals. And displayed on the full color LED display.
So how does the LED video processor work, you know? Let me introduce you to the following small series.
1, resolution specification conversion: In general, image sources (such as Blu-ray DVD, computer, HD player, etc.) provide fixed signal resolution (refer to VESA, ITU, SMPTE, etc.). And the modular spliced display of the LED display screen allows its resolution to reach almost any value. The video processor converts the various signal resolutions to the actual physical display resolution of the LED display.
2, color space conversion: LED display color gamut is very wide, and the color space of most image signals is relatively small (such as NTSC). In order for an LED display to have an excellent image display effect, color space conversion is required.
3, the bit depth is improved: the current gray level of the LED display has been increased to 16 bits, 17 bits, however, the input signal source is mostly only 8 bits. Therefore, with the advent of the high-definition display era, the application of 10-bit or even 12-bit processing technology in video processors has become an unstoppable trend.
4. Zoom: During the resolution specification conversion process, the image needs to be scaled. The full image can be displayed on the screen regardless of whether the resolution is increased or decreased.
5. Image Processing and Enhancement Technology: Digital image processing technology has developed from the 1920s to the present, and a large number of patented technologies have appeared. For example, DCDi, ACC2, ACM3D and other Emmy-winning Faroudja laboratories have a range of patented technologies. These techniques undoubtedly greatly enhance the visual effect of the image.
