Description
Technical Field
The invention relates to the technical field of remote control, in particular to a remote image color temperature adjusting method based on field program director.
Background
The color temperature refers to the real restoration of the color of a shot object and is a key index for field shooting. Physically, an object exhibits a specific color because light reflected from the surface of the object exhibits the specific color in the human visual system when the light is irradiated onto the surface of the object. The color of an object as observed by the human eye is related not only to the reflective properties of the object but also to the light rays directed towards the object.
Under different light irradiation, when people directly look at objects with naked eyes, the feeling of the same color can be basically kept constant, but the camera cannot. Because of the imbalance of the output of the camera under different light irradiation conditions, the color distortion phenomenon of the image output by the camera occurs, and the quality of the field production program is directly influenced.
In the conventional technology, it is generally ensured that no color distortion occurs in images output by a multi-camera on site by a method based on talkback collaboration or single prompt collaboration by a director and a photographer, but the method is very inconvenient and has large adjustment error. Especially in the environment of large-scale on-site program production, due to the broadcasting guide classification and the cross-space distribution of the cameras, the traditional technology can not meet the working requirement of precise cooperation of on-site program production basically, and the quality of program production is greatly influenced.
