Abstract

The invention relates to a self-adaption zooming system and a self-adaption zooming method, belonging to the technical field of zooming. The self-adaption zooming system comprises a front fixing group, a first zooming group, a second zooming group, a first compensation group, a second compensation group and a rear fixing group which are sequentially and coaxially arranged, wherein a detector is arranged on an output light path of the rear fixing group and is used for imaging the light of the rear fixing group; the output end of the detector is connected with a control component; the control component is connected with the first zooming group, the second zooming group, the first compensation group and the second compensation group in a control manner and is used for controlling the first zooming group, the second zooming group, the first compensation group and the second compensation group to move in the axial direction according to the imaging situation of the detector, thereby achieving continuous zooming of the system. By adopting the zooming system provided by the invention, the imaging quality is good within the range of 10-400mm, the zooming achieving route is simple, and a small amount of lenses are used.

Description

technical field [0001] The invention relates to an adaptive zooming system and method, and belongs to the technical field of zooming. Background technique [0002] Zoom technology has many advantages and is widely used in many fields. Zoom technology usually has two methods: discrete zoom and continuous zoom. The discrete zoom method is usually that the field of view of the system changes discretely. As a result, the problem of not being able to proceed continuously. In some existing zooming technologies, when it is necessary to realize continuous zooming, there are usually disadvantages such as complex zooming realization paths and a large number of lenses to be used. Contents of the invention [0003] The object of the present invention is to provide an adaptive zoom system and method to solve the problems in the prior art that the path for zooming is complicated and the number of lenses to be used is large. [0004] The present invention provides an adaptive zoom syst...
