Embodiment Construction

[0023] like figure 1 As shown in the figure, a layer function card of the present invention mainly includes a layer signal distribution module 1, a layer signal clock reorganization module 2, a signal drive strengthening module 3, a signal preprocessing module 4, a video image special processing chip 5, a layer / Image signal output processing module 6, layer signal selector 7, signal processing module 8 and control unit 9; wherein:

[0024] The layer signal distribution module 1 is connected to the matrix mainboard 10, receives one layer / image signal from the matrix mainboard 10, and passes the layer signal through the layer signal clock recombination module 2 and the signal drive enhancement module 3 in turn to perform the layer signal. After the clock is reorganized and the signal drive is strengthened, it is output as a layer signal; the image signal is sent to the video image special processing chip 5 through the signal preprocessing module 4 for image data processing, and...

Abstract

The present invention is a layer function card and its image processing method, comprising a layer signal distribution module, a layer signal clock recombination module, a signal drive enhancement module, a signal preprocessing module, a dedicated video image processing chip, and a layer / image signal output Processing module, layer signal selector, signal processing module and control unit; one layer function card can realize the combination of 4 layer signals, and two layer function cards can realize the combination of 7 layer signals, that is, the first After the four image signals of the first layer function card are merged, a complete layer is formed. After the complete layer signal is extracted by the layer signal selector, it is returned to the matrix main board through the layer signal return channel. Layers are merged with other 3 input image signals on the layer function card to form 7 layers. Therefore, the present invention can realize unlimited layer superposition in this device, and by receiving layer signal input from other devices, Realize multi-device layer overlay.

Description

technical field [0001] The invention relates to a layer function card and an image processing method thereof. Background technique [0002] With the increasing maturity of LED technology, large-area LED screens are gradually being promoted. In the process of promoting large-area LED screens, in order to realize the multi-screen display of large LED screens, the infinite creative space of artists can become In reality, people have developed LED video processors that support multi-screen display. [0003] In practical applications of security monitoring, administrative management, military command, exhibition, scientific research and education, multi-screen display of LED large screen is required, and video processor is required to have multi-screen display function. The existing LED video processors in the market can generally only support four-split screens, which greatly limits the on-site construction wiring and creativity, which in turn causes great application troubles ...
