Embodiment Construction

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0021] The embodiment of the present invention aims at the problem of poor focusing performance and poor focusing speed of cameras in the prior art, and provides a terminal focusing method and a terminal, which can quickly complete focusing without adding hardware, which not only saves costs, but also improves the user experience effect.

[0022] Such as figure 1 As shown, the embodiment of the present invention provides a terminal focusing method, including:

[0023] Step 11, acquiring a preview image of the object to be photographed by the lens, and detecting the preview image;

[0024] Step 12, when it is detected that there is an object to be detected in the object to be photographed in the preview image, determine the first area of ​​the object to...

Abstract

The invention provides a terminal focusing method and a terminal. The terminal focusing method comprises the following steps: a preview image, taken via a lens, of an object to be photographed is obtained and detected; when that an object to be detected exists in the object to be photographed in the preview image is detected, a first area of the object to be detected in the preview image is determined; according to a first pre-established mapping relation, and first shooting distance corresponding to the first area is determined; areas of a sample object, photographed at different shooting distances via the lens, in the preview image are recorded in the first mapping relation; an focus can be brought on an object to be photographed according to the first shooting distance. Rapid focusing can be realized, cost can be saved, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of image capturing, and in particular to a terminal focusing method and a terminal. Background technique [0002] Today's camera focusing technology is divided into the following categories: [0003] Contrast focusing system. The principle is to find the position of the lens with the maximum contrast according to the contrast change of the picture at the focal point, that is, the position of accurate focus. [0004] Phase detection focusing system. Phase detection AF requires a little more hardware than contrast AF. Consists of a split lens and a linear sensor Image is separated into 2 images by the split lens, and then the distance between the two images is detected by the linear sensor. Compared with the contrast method that needs to go back and forth many times to "miss" the exact focus position to focus, the phase focus can judge whether the current focus position is front or back through the...
