Embodiment Construction

[0077] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0078] With the popularization of mobile phones, and due to the characteristics of mobile phones being easy to carry, using mobile phones to take pictures has become the choice of most people. However, when shooting scenes displayed on monitors such as computers and TVs, it is inevitable that seemingly "interesting" moiré patterns will appear. This affects the image quality of the original imag...

Abstract

The invention relates to a method and a device for controlling lens focusing, thereby effectively suppressing Moire patterns generated during image acquisition. The method comprises the steps: determining a first focusing position in a process of driving a lens group to move in a preset interval; determining a second focusing position based on the first focusing position and a preset deviation value; and driving the lens group to move to the second focusing position. According to the technical scheme of the invention, the coherence between the detail resolution of the photographed object and the repetition unit space frequency of the photosensitive element of the image collector can be reduced, and the moire generated during image collection can be effectively suppressed.

Description

technical field [0001] The present disclosure relates to the field of Internet technologies, and in particular to a method and device for controlling lens focusing. Background technique [0002] With the popularization of mobile phones, and due to the characteristics of mobile phones being easy to carry, using mobile phones to take pictures has become the choice of most people. However, when shooting scenes displayed on monitors such as computers and TVs, it is inevitable that seemingly "interesting" moiré patterns will appear. This affects the image quality of the original imaging to a certain extent. Therefore, how to effectively reduce the appearance of moiré is a technical problem that needs to be solved at present. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, embodiments of the present disclosure provide a method and device for controlling lens focusing, which can effectively suppress moiré generated when...
