Problems solved by technology

[0003] In the process of using an endoscope, it is difficult to meet the needs of a single magnification image, so an adapter that can zoom is needed, which can present images of different magnifications for users to observe. For example, application number CN200420020588.9 provides a zoom adapter
However, the current zoom adapter needs to manually adjust the focus again to obtain a clear image after changing the magnification every time, which brings inconvenience to the user and reduces efficiency. , no need to adjust the focus when changing the magnification again, a zoom adapter that can continuously obtain clear images

Embodiment Construction

[0030] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific implementation manners described here are only used to explain relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only parts related to the present disclosure are shown in the drawings.

[0031] It should be noted that, in the case of no conflict, the implementation modes and the features in the implementation modes in the present disclosure can be combined with each other. The present disclosure will be described in detail below with reference to the drawings and embodiments.

[0032] Zooming refers to zooming in and out of an image by changing the focal length, and focusing refers to adjusting the position of the focal point to make the image clearer. In the existing zoom adapter, in order to change the image magnification, it is necessary to manually...

Abstract

The present invention discloses a zooming adapter optical system. The system comprises in order from an object side to an image side: a zooming lens set, a fixed lens set, a zooming lens set and a compensation lens set, the zooming lens set is configured to perform focusing processing of an object distance to obtain a clear image; the fixed lens set is configured to remain the position unchanged in the process of focusing processing and zooming process; the focusing lens set is configured to perform linear movement in an optical axis direction to change the image amplification ratio; and the compensation lens set is configured to perform non-linear movement to compensate the position of focus points with different enlargement ratios for movement in the optical axis direction.

Description

technical field [0001] The present disclosure relates to a zoom adapter optical system and a control method thereof, a zoom adapter and an endoscope system. Background technique [0002] The adapter is used for cooperating with the endoscope and connecting the camera device at the same time, so as to transmit the image detected by the endoscope to the camera device, so that the user can observe better. [0003] In the process of using an endoscope, it is difficult to meet the needs of a single magnification image, so an adapter that can zoom is needed, which can present images of different magnifications for users to observe. For example, application number CN200420020588.9 provides a zoom adapter. However, the current zoom adapter needs to manually adjust the focus again to obtain a clear image after changing the magnification every time, which brings inconvenience to the user and reduces efficiency. , It is a zoom adapter that can continue to obtain clear images without ...
