Problems solved by technology
[0011] In order to solve the above problems, the present invention provides a video interface-oriented signal adjustment system and its method, which effectively avoids the pins of the image acquisition module used to transmit video signals in the prior art and the corresponding pins to be connected on the digital video interface. When the pins are connected, there will be problems that cross each other or are not conducive to wiring, so that the pins of the image acquisition module used to transmit video signals and the pins of the digital video interface are on the connection and the wiring of the PCB where the digital video interface is located. Defects that add complexity and affect their electrical characteristics

Embodiment Construction
[0040] The present invention adds an asynchronous FIFO and a remapping module inside a chip such as a digital video interface, uses software to perform mapping configuration according to requirements, and remaps the video signal required to be transmitted by the digital video interface, and then enters subsequent video image sampling and processing. The remapping module restores the required digital video interface signals inside the chip.
[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0042] Such as Figure 1-Figure 3As shown, the signal adjustment system facing the video interface includes an image acquisition module such as a CMOS image sensor and a digital video interface; some pins on the digital video interface are respectively connected with those on the image acquisition module such as a CMOS image sensor for transmission The pins of the video signal are connected in a way that facilitate...

A video interface-oriented signal adjustment system and method thereof, comprising an image acquisition module and a digital video interface; several pins on the digital video interface are respectively connected to pins for transmitting video signals on the image acquisition module according to It is beneficial to route the PCB where the digital video interface is located or connect in a way that can minimize the number of layers of the PCB. The digital video interface includes a remapping module and a gating module as a mapping configuration interface. It effectively avoids the problem that the pins of the image acquisition module used to transmit video signals and the corresponding pins on the digital video interface to be connected in the prior art will cross each other or be unfavorable for wiring when connecting, so that the image acquisition module can be used The pins for transmitting video signals and the pins of the digital video interface increase the complexity and affect the defects of its electrical characteristics on the connection and the routing of the PCB where the digital video interface is located.
Description
technical field [0001] The present invention relates to the technical field of video interface, and also to the technical field of video signal adjustment, in particular to a video interface-oriented signal adjustment system and method thereof, and in particular to a digital video interface-oriented signal remapping system and method thereof. Background technique [0002] The main function of the video interface is to output the video signal to the external equipment, or collect the video signal collected from the outside. With the continuous development of video technology, people have successively adopted various types of video interfaces in order to present high-definition and high-quality video. At the same time, the role of the video interface is also constantly enriched. [0003] With the continuous improvement of people's requirements for image display quality, the traditional technology of transmitting and displaying multimedia signals in analog mode can no longer m...
