LED video processor is also called screen processor, image converter, video controller, image processor screen converter, video format converter independent video source.
LED Video processor is the picture processor LED full color display screen birth, growth and maturity of the whole witness and key equipment, LED video processor advantages and disadvantages directly affect the display effect of the LED display. LED video processor and the display of the binding of the use of the LED video processor is greatly facilitated by the end-user wide range of applications to improve the depth of the use of the LED display.
Full-color LED multi-screen video image processor is a national high-tech enterprises launched for the full-color LED high-performance image processing and
control equipment. The device integrates years of rich experience in video image processing, high-definition signal processing and display, using patented technology hardware design, combined with the special requirements of full-color LED screen display design, can simultaneously accept and process a variety of different video graphic signals, and display on the full-color LED display.
So how does the LED video processor work, do you know? The following small introduction to you.
First, the resolution specification conversion: In general, the image signal source (such as Blu-ray DVD, computer, high-definition playback box, etc.) to provide the signal resolution have fixed specifications (refer to VESA, ITU, SMPTE and other standards), and the modular splicing of the LED display display, so that its resolution can be almost any value.
Video processor will be a variety of signal resolution converted to the actual physical display resolution of the LED display.
Second, the color space conversion: LED display of the color gamut is very wide, and most of the image signal color space is relatively small (such as NTSC). In order for the LED display to have excellent image display effect, must be color space conversion.
Third, the depth of the bit to improve: the current grayscale level of the LED display has been raised to 16 bits, 17 bits, however, most of the input signal source is only 8 bits. Therefore, with the arrival of the high-definition display era in the footsteps of 10-bit or even 12-bit processing technology in the
video processor application has been the trend.
Fourth, scaling: resolution specifications conversion process, the need for image scaling, whether the resolution increases or decreases, you can let the screen display a complete image.
Fifth, image processing and enhancement technology: digital image processing technology from the 1920s to the present, a large number of patented technologies. For example, DCDi, ACC2, ACM3D and other Emmy Award-winning Faroudja laboratory of a series of patented technologies. These technologies undoubtedly make the visual effect of the image has been greatly improved.
