example 2

[0094] Example 2, combined with Example 1, the second weight is 0.1, then the first weight is: the product of the difference between 1 minus the second weight (ie 0.1) and the initial weight of the target depth data.

[0095] In this way, by combining the focus of the depth camera and the phase focus camera, the focus error is corrected, and the influence of the phase focus on the final effect is effectively avoided, further improving the accuracy of the focus.

[0096] Optionally, in the embodiment of the present application, after the above step 104, the focusing method provided in the embodiment of the present application further includes step 105:

[0097] Step 105 , the focusing device adjusts the current focal length of the phase focus camera by adjusting the sharpness value.

[0098] Exemplarily, the focusing device may adjust the current focal length of the above-mentioned phase focus camera by adjusting the sharpness value (or FV value (ie focus value)) of the above-m...

Abstract

The invention discloses a focusing method and device and electronic equipment, and belongs to the technical field of communication. Specifically, the method comprises the following steps: collecting a first image collected by a depth camera and a second image collected by a phase focusing camera; collecting a first weight of target depth data of an image corresponding to a first region of the first image; collecting a second weight of an initial focal length of the phase focusing camera based on a confidence coefficient of an image corresponding to a second region of the second image; adjusting the focal length of the phase focusing camera according to the first weight and the second weight; wherein the first image and the second image are respectively collected by a depth camera and a phase focusing camera for the same shooting object at the same time; the second region is a region corresponding to the first region in the second image.

Description

technical field [0001] The present application belongs to the technical field of communications, and in particular relates to a focusing method, device and electronic equipment. Background technique [0002] With the continuous development of electronic information technology, the functions of electronic devices (such as smart phones, tablet computers, etc.) are becoming more and more powerful, and the demand for taking pictures through electronic devices is increasing. [0003] At present, during the phase focusing process of electronic devices, for some small objects, such as pens, flowers or leaves, when the user takes a photo, he wants to focus on the above-mentioned small objects, but because the subject is too small, or because the backlight or the difference in depth of field between the front and the back is not When it is too large, the focus will be inaccurate and affect the photo effect. Contents of the invention [0004] The purpose of the embodiments of the p...
