Embodiment 1

[0092] An embodiment of the present invention provides a focusing method, such as image 3 As shown, the method may include:

[0093] S101. When a focusing instruction is received, collect a first image through an image sensor, and obtain an initial focal length and shooting parameters of the camera.

[0094] It should be noted that the focusing method provided by the embodiment of the present invention is implemented in a scene where a photo is taken on a terminal.

[0095] Focusing refers to adjusting the focal distance when using a camera. Focusing is also called focusing on light and focusing. Focusing is the process of changing the distance and the distance between animals by using the focusing mechanism on the camera or the camera on the terminal to make the image of the subject clear.

[0096] Wherein, the phase focus realizes the automatic focus by detecting the phase shift of the image. A grid plate composed of parallel lines is placed at the position of the light-...

Embodiment 2

[0122] An embodiment of the present invention provides a focusing method, such as Figure 6 As shown, the method may include:

[0123] S201. Receive a focus instruction.

[0124] It should be noted that, in the embodiment of the present invention, the user uses the terminal to take pictures. When the user clicks on the camera application to open the camera application, the camera button is triggered or the display screen of the terminal is clicked, that is, the terminal receives a focus instruction.

[0125] S202. When a focusing instruction is received, collect a first image through an image sensor, and obtain an initial focal length and shooting parameters of the camera.

[0126] The description of the detailed process of this step is consistent with the description process of S101 in the previous embodiment, and will not be repeated here.

[0127] It should be noted that the process of obtaining the initial focal length in the embodiment of the present invention may be as...

Embodiment 3

[0155] Such as Figure 10 As shown, the embodiment of the present invention provides a terminal 1, the terminal 1 may include:

[0156]The acquisition unit 10 is configured to, when the receiving unit 11 receives the focusing instruction, the acquisition unit 18 acquires the first image through the image sensor, and acquires the initial focal length and shooting parameters of the camera.

[0157] The determining unit 12 is configured to determine a first depth-of-field range for capturing the first image according to the initial focal length and the shooting parameters acquired by the acquiring unit 10 .

[0158] The calculation unit 13 is configured to calculate at least two first focal lengths by adjusting the position of the shooting motor within the first depth of field range determined by the determination unit 12 .

[0159] A focusing unit 14, configured to focus and aim the first image according to the at least two first focal lengths calculated by the calculation unit...

Abstract

The embodiment of the invention discloses a focusing method and a terminal. The focusing method and the terminal can rapidly realize focusing, are simple in operation and have the diversity. The method comprises: when a focusing instruction is received, collecting a first image through an image sensor, and obtaining an initial focal length and the camera parameters of a camera; according to the initial focal length and the camera parameters of the camera, determining the first field depth range shooting the first image; in the first field depth range, calculating at least two first focal lengths through adjusting the position of a camera motor; and performing focusing aiming of the first image according to the at least two first focal lengths, and obtaining the at least two second images corresponding to the at least two first focal lengths after focusing.

Description

technical field [0001] The present invention relates to image processing technology in the field of information processing, in particular to a focusing method and a terminal. Background technique [0002] With the rapid development and gradual popularization of mobile terminals, mobile terminals have become one of the indispensable tools in people's daily life, and mobile terminals with camera devices are widely favored by users. In order to obtain a better shooting experience, people have higher and higher requirements for the camera function of the mobile terminal, which not only require the pixel of the camera device to be improved, but also require the camera device to increase the shooting speed. Among them, the shooting speed is mainly determined by the focusing method. [0003] At present, most of the mobile terminals on the market adopt a contrast focusing method or a phase focusing method, and the target focusing position is accurately found by driving the lens to ...
