Method for operating a video camera, Methods to increase and decrease the degree of magnification and video camera operated by the method.

摘要

The invention relates to a method for operating a video recorder, a method for improving and reducing its amplification degree, a video recorder operated by this method, especially an operating video recorder, so as to ensure that the amplification speed of the photographed object changes rapidly. The amplification in Scotland is realized by quickly converting the plane change electronic factor provided by the image Senal processing circuit. Before or after the change of the electronic factor of the plane change,At the same time, the electronic factors of plane descent and the mechanical factors of plane change are also compensated by the optical layout of the camera. The compensation speed of the two factors at the same time is consistent with the actual operation of the mechanical components driven by the laser optical layout.
