Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0036] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first direction could be termed a second direction, and, similarly, a second direction could be termed a first direction, without departing from the scope of the present application. Both the first direction and the second direction are directions, but they are not the same direction.

Abstract

The invention relates to a focusing method, a device, electronic equipment and a computer readable storage medium. The method comprises the steps: obtaining a first phase difference value and a second phase difference value of a detection image corresponding to a first shooting posture, and determining a focusing mode of the electronic equipment according to the confidence coefficients corresponding to the two phase differences; when the focusing mode is phase detection automatic focusing, detecting a second shooting posture of the electronic equipment and deflection data of the electronic equipment relative to the first shooting posture; determining a target direction and a corresponding target phase difference according to the deflection data, the first phase difference value and the second phase difference value; and controlling the electronic equipment to focus according to the target phase difference. The target direction and the target phase difference value corresponding to the target direction are determined according to the deflection data of the electronic equipment and the confidence coefficient of the two phase differences, and the phase difference value of the two directions after the electronic equipment is subjected to angle deflection does not need to be calculated again, so that the calculation complexity of a focusing algorithm is reduced; the focusing rate of the electronic equipment in the deflection attitude is improved.

Description

technical field [0001] The present application relates to the image field, and in particular to a focusing method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] When capturing an image, in order to ensure that the image is captured clearly, it is usually necessary to focus the electronic device. The so-called focusing refers to the process of adjusting the distance between the lens and the image sensor. Currently, a relatively common focusing method includes phase detection auto focus (English: phase detection auto focus; PDAF for short). [0003] In the related art, in order to perform phase detection autofocus, some phase detection pixels (also referred to as shielded pixels) can be set in pairs among the pixels included in the image sensor, wherein each phase detection pixel is centered on One of the phase detection pixels performs left occlusion, and the other phase detection pixel performs right occlusion. In thi...
