Description

Technical Field

[0001] The invention belongs to the technical field of cameras, in particular to a camera capable of realizing free conversion between horizontal and vertical screens. Background Art

[0002] In the field of real-time news interviews, the difference between horizontal and vertical screens in the same interview shooting scene may have a huge impact on the composition and level of the real-time image. When shooting in horizontal screen, the image has a larger display space in the horizontal direction, and has the characteristics of being wide and open, so it is suitable for shooting large scenes, such as background distant photos, group photos, etc.; when shooting in vertical screen, the image is compressed in the horizontal direction, but has a larger display space in the vertical direction, which is more suitable for showing the details of the interviewed people and the depth of the photos. The current general solution is to use two camera positions to record the horizontal and vertical versions of the video at the same time, and adapt the real-time interview content by real-time switching. In addition, the current mainstream professional interview cameras generally adopt an integrated structural design in which the aperture lens combination is placed at the front end of the camera, and the CMOS image sensor and viewfinder / screen are placed at the back end of the camera. The whole machine is large in size and heavy in weight, suitable for fixed operation on a tripod. When the interview needs to be transferred or moved, the operator needs to carry it on his shoulder, which is not easy to operate, and the maintenance process is cumbersome and time-consuming.
