[0002] In today's digital high-speed development era, new media technology is increasingly mature, and the audience's quality requirements for live pictures have reached a new height, no longer satisfied with traditional live pictures, but put forward higher requirements on the fineness of composition, the richness of color and the level of depth of field, etc. In order to meet the needs of the audience, the picture quality of television live broadcast must be continuously improved, and the production of film feeling of live picture color, complete composition, background blur and other elements is the problem we want to solve at present.
[0003] At present, the main way to present the film feeling of live picture is to adjust the color of single camera through third-party equipment and process the video with color adjusting software in video post-production. A traditional live picture production system mentioned in Chinese patent CN204669511U adjusts the color of different cameras through multiple independent controllers. This way is not only cumbersome to operate, but also difficult to achieve unified coordination between controllers, resulting in uneven picture effect. At the same time, the post-processing software processing method is time-consuming and labor-intensive, and it is difficult to use in real time during live broadcast. UTILITY MODEL CONTENT

[0009] The ultra-high-definition 4K television truck system is a signal production carrier, and the channel camera, the high-speed channel camera and the pan-tilt camera are connected with the ultra-high-definition 4K television truck system. The pan-tilt camera is connected to the 3500RCP control unit through a network cable, the connection mode of the 3500RCP control unit is set to Bridge mode, and the IP addresses of the pan-tilt camera and the 3500RCP control unit are set in the same network segment, so as to realize the control of the pan-tilt camera by the 3500RCP control unit. The other end of the 3500RCP control unit is connected to a gigabit switch, and is in communication connection with the MCU central control unit through the gigabit switch, and the IP addresses of the MCU central control unit and the 3500RCP control unit are in the same network segment, so as to realize the centralized management of the MCU central control unit on the 3500RCP control unit. The MCU central control unit is in communication connection with the oscilloscope equipped in the ultra-high-definition television truck system, and is used for the centralized management of the color and composition of the pictures taken by each camera, so as to generate a live picture with a film feeling in real time. The MCU central control unit controls the channel camera and the gigabit switch equipped in the truck to centrally manage the color, composition and the like of the pictures taken by each camera. This centralized and unified control mode is different from the traditional single camera color adjustment mode, and the efficiency is improved.
[0010] Further, a special LUT for the pan-tilt camera is made, and the special LUT module is used to optimize the picture effect of the pan-tilt camera, so that the color and contrast of the picture can be quickly and accurately adjusted according to different shooting scenes and requirements, thereby providing strong technical support for the production of a film picture.
[0011] Further, the adjustment parameters of the camera color matrix are made, and the color matrix adjustment parameter module is used to accurately adjust the color performance of the channel camera, so that the color of the picture is more rich and realistic, and the artistic appeal of the picture is enhanced.
[0012] Further, the specific parameters of the picture white balance and black cut are determined, and the picture white balance and black cut parameter module is used to set the white balance and black cut parameters of the picture taken by the camera. The accurate white balance setting can ensure that the color of the picture is real and natural, and the reasonable black cut parameter can enhance the contrast and level of the picture. In actual operation, the best white balance and black cut parameters can be determined through testing and adjustment of different scenes.
[0013] Further, the composition ratio of the pan-tilt camera and the channel camera is determined, and the composition ratio adjustment module is used to determine the composition ratio of the pan-tilt camera and the channel camera. Through careful design of the composition ratio, the picture can be more beautiful and atmospheric, and the film feeling of the live picture can be highlighted.
[0014] Compared with the way of adjusting color of single camera by third party equipment or processing video by color matching software in post-production, the color matching scheme of the super high definition 4K television mobile broadcast vehicle is more efficient, combines the picture effect of film feeling with the television broadcast technology, and can be directly used in live broadcast without adjusting the picture by consuming manpower and material resources in post-production, so that the centralized and unified control mode is different from the traditional single camera color adjustment mode, and the work efficiency is greatly improved.
