LED video processor principle
In the process of use, LED video processor generally needs to complete the following processes:
I. resolution and specification conversion: generally, the signal resolution provided by image sources (such as blu-ray DVD, computer, hd playback box, etc.) has a fixed specification (refer to standards like VESA, ITU and SMPTE), while the modular splicing display of led display makes its resolution almost arbitrary. The video processor converts various signal resolutions into the actual physical display resolution of the led display.
2. Color space conversion: LED display has a wide color range, while most image signals have a small color space (such as NTSC). In order for the led display to have a good image display effect, color space conversion must be carried out.
Iii. Bit depth promotion: currently, the gray level of led display has been increased to 16 and 17 bits, but most input sources are only 8 bits. Therefore, with the advent of the high-definition display era, the application of 10-bit and even 12-bit processing technology in video processors has become an inevitable trend.
4. Zoom: in the conversion process of resolution specification, the image needs to be zoomed and zoomed. Whether the resolution is increased or decreased, the whole image can be displayed on the screen.
V. image processing and enhancement technology: digital image processing technology developed from the 1920s to the present, a large number of patented technologies have emerged. For example, DCDi, ACC2, ACM3D and other emmy award-winning Faroudja laboratory's series of patented technologies. These techniques have undoubtedly improved the visual effects of images.
