The LED video processor is a dedicated video signal processor for LED displays. The task it needs to accomplish, in simple terms, is to convert image signals from external sources (such as Blu-ray DVDs, computers, HD playback boxes, etc.) into signals that LED displays can accept. In this process, the LED video processor generally needs to complete the following processing: First, the resolution specification conversion: In general, the image signal source (such as Blu-ray DVD, computer, HD player, etc.) provides a fixed signal resolution. The specifications (refer to VESA, ITU, SMPTE and other standards), and the modular display of the led display, so that its resolution can be almost any value. The LED video processor converts a wide variety of signal resolutions into the actual physical display resolution of the led display. Second, color space conversion: LED display color gamut is very wide, and the color space of most image signals are relatively small (such as NTSC). In order for the LED display to have an excellent image display effect, color space conversion is necessary. Third, 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, following the arrival of the era of high-definition display, the application of 10-bit or even 12-bit processing technology in video processors has become an irresistible trend. 4. Zoom: During the resolution specification conversion process, the image needs to be scaled. Whether the resolution is increased or decreased, the complete image can be displayed on the screen. V. 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 emerged. For example, DCDi, ACC2, ACM3D and other Emmy-winning Faroudja laboratories a series of patented technologies. These techniques undoubtedly make the visual effect of the image greatly improved.
