Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, and more specifically, to a control circuit and device for automatic image locking acquisition in a broadcast control station. Background Technology

[0002] Currently, the image acquisition method for broadcast control stations on the market is basically to use PTZ cameras. However, the images captured by PTZ cameras are not necessarily ideal videos. From multiple perspectives, the use of PTZ cameras in broadcast control stations relies on manual control using levers in the control panel. If the person being captured is far away or moving, the image will not be centered, which is not ideal for the broadcaster. Moreover, PTZ cameras are very expensive, and during use, an operator is required to control the lens direction. Before use, a network cable must be plugged in and the IP address must be set up, which is an obstacle for those who are not familiar with the settings.

[0038] It needs to be explained, such as Figure 2 As shown, the image processing chip 1 can be of the SSD261Q type, etc., and there is no limitation on it. Other existing chip models with the functions required by this application can also be used.
