Full-color LED display of the video processor has what effect
Video processor is full-color LED display birth, growth and maturity of the whole witness and iconic equipment, and now LED dedicated video processing equipment in the process also gradually mature, here we come to understand the full color LED display Of the video processor:
The same time as the above-
LED video processor is a dedicated LED video processor, and it needs to complete the task is to be from the external image signal into the LED display can accept the signal. In this process, LED video processor generally need to complete the following process:
The same time as the above-
1, the resolution of the standard conversion: In general, the image signal source (such as Blu-ray DVD, computer, high-definition playback box, etc.) to provide the signal resolution has a fixed specification (refer to VESA, ITU, SMPTE and other standards), and led display The modular splicing of the screen allows the resolution to be almost any value. The video processor converts the various signal resolutions into the actual physical display resolution of the LED display.
The same time as the above-
2, color space conversion: LED display color gamut is very wide, and most of the image signal color space is relatively small (such as NTSC). In order to make full-color LED display with excellent image display, color space conversion must be carried out.
The same time as the above-
3, bit depth upgrade: the current full-color LED display gray scale has been raised to 16 bits, 17 bits, but the input signal source is only 8 bits. Therefore, following the arrival of the era of high-definition display, 10-bit or even 12-bit processing technology in the application of video processors is the trend.
The same time as the above-
4, image processing and enhancement technology: digital image processing technology from the 20th century, 20 years to the present development, there have been a large number of patented technology. Such as DCDi, qACC2, ACM3D and other Emmy Award Faroudja laboratory a series of patented technology. These technologies will undoubtedly make the visual effect of the image has been greatly improved.
The same time as the above-
5, zoom: resolution specifications conversion process, the need to scale the image, whether it is increased or reduced resolution, you can make the screen display a complete image.
