Problems solved by technology

However, on the one hand, the image of the live view frame is obtained by down-sampling, and the resolution is reduced. Moreover, due to the limitations of the imaging system, it will increase the error of manual focus
On the other hand, in the process of manual focusing, the user moves the focus motor by adjusting the roller to make the lens move to achieve the effect of gradually clearing the image. When the lens reaches the focus state, most users cannot confirm whether the current lens is in the focus state. Generally, you will continue to adjust the scroll wheel to produce the defocus effect, and then adjust to the previous clear state. This operation causes the breathing effect in the focusing process to be obvious, and the user readjusts the defocused lens to a clear state. Rely heavily on user experience
The lack of an effective auxiliary manual focus method will increase the difficulty of focusing the lens and reduce the quality of the image

Abstract

A manual focus assisting method includes: acquiring an image generated by light of the autofocus lens during manual focusing on an autofocus lens; and determining an image related to an in-focus stateof the autofocus lens a focus parameter value; determining a focus position of the autofocus lens based on the focus parameter value. This method can help users achieve precise manual focus. A manualfocus assist device for performing the above method. An unmanned aerial vehicle includes the above auxiliary device.

Description

technical field [0001] The invention relates to the field of photographing, in particular to a manual focus assisting method, a manual focus assist device and an unmanned aerial vehicle. Background technique [0002] Manual focus is a process in which the user determines the focus position of the autofocus lens by observing the clarity of the image in the live view frame with the naked eye. However, on the one hand, the image of the real-time viewfinder frame is obtained through down-sampling, and the resolution is reduced. Moreover, due to the limitations of the imaging system, it will increase the error of manual focus. On the other hand, in the process of manual focusing, the user moves the focus motor by adjusting the roller to make the lens move to achieve the effect of gradually clearing the image. When the lens reaches the focus state, most users cannot confirm whether the current lens is in the focus state. Generally, you will continue to adjust the scroll wheel to ...
