The video processor is the full-color LED display was born, grow and mature to witness the entire process and marking equipment, LED dedicated video processing equipment in this process has gradually become mature, LED video processor directly affects LED screen display effect.
In general, LED video processor, is dedicated to LED video processor. But it needed to complete the task, in simple terms, is from an external (e.g. Blu-ray DVD, computers, high-definition playback box ) image signal into LED display can receive signals. In this process, the LED video processor is generally required to complete the following process:
A bit depth, lifting: the current LED display gray level has been raised to 16 bit, 17 bits, however the input signal source most of only 8 bits. Therefore, with high-definition era footsteps, 10 bit and 12 bit processing technology in the video processor in the application is already represent the general trend.
Two, resolution specification conversion: in general, the image signal source ( e.g. Blu-ray DVD, computers, high-definition playback box ) to provide signal resolution have fixed specifications ( VESA, ITU, SMPTE standards ), and LED display modular splicing display, the resolution can be almost any numerical. The video processor will be a variety of signal resolution is converted to LED display of the actual physical display resolution.
In three, the scaling: resolution specification conversion process, the need for image scaling, either the resolution increase or decrease, can let the screen display image.
Four, color space conversion: LED display color gamut is very wide, and the majority of image signal color space are relatively small ( such as NTSC ). In order to make the LED display screen with excellent image display effect, must undertake the color space conversion.
Five, image processing and enhancement technology: digital image processing technology in the nineteen twenties development up to now, there has been a large number of patent technology. For example, DCDi, ACC2, ACM3D and Faroudja laboratory won Emmy Awards for a series of patent technology. These techniques will undoubtedly make the image visual effect has been greatly improved.
The company is relying on the Chinese Academy of Sciences and Tsinghua University technology, for radio and television, full-color large screen display control, video conferencing and communication, medical imaging and the education and training in areas such as the provision of professional video and audio processing equipment and technical services, users throughout the various provinces and regions.
