Application of video processor in Full-color LED display
Video processor is the birth of full-color LED display, growth and maturity of the whole witness and the symbol of equipment, today's special LED video processing equipment in this process is also gradually maturing, led video processor, the pros and cons of direct impact on the display of LED display effect.
Overall, LED video processor, is the LED dedicated video processor. The task it needs to accomplish, in short, is to convert the image signal from the outside into an acceptable signal from the LED display. In this process, the LED video processor generally needs to complete the following process:
1.resolution specification conversion: The video processor converts various signal resolutions to the actual physical display resolution of the led display.
2. color space conversion: LED display's color gamut is very wide, and most of the image signal's color space is relatively small (such as NTSC). In order for the led display to have excellent image display, color space conversion is necessary.
3. Bit depth enhancement: The gray level of the current led display has been raised to 16 bits and 17 bits. However, the input signal source is mostly 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 is a general trend.
4. Zoom: In the resolution conversion process, the image needs to be zoomed. No matter whether the resolution is increased or decreased, the entire image can be displayed on the screen.
5. Image Processing and Enhancement Technology.
