Embodiment Construction

[0040] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] Such as Figure 1-5 As shown, a full-frame focusing method provided by an embodiment of the present invention includes the following steps:

[0042] 101. Divide the whole frame into multiple first focus areas according to predetermined rules;

[0043] Specifically, the whole screen is divided to form a plurality of different first focus areas, the cutting rule is preset, and the predetermined rule may be equal division, such as figure 1 As shown, divide the entire screen into six rows and eight columns and so on. The predetermined rule may also be to divide the entire screen into multiple first focus areas of different sizes. The predetermined rule is determined according to the actual demand and the processing capability of the camera ...

Abstract

The invention discloses a full-image focusing method and a camera. The full-image focusing method comprises the following steps of: according to preset rules, partitioning a full image into a plurality of first focusing areas; respectively carrying out focusing on each first focusing area to obtain a first lens running distance value of each first focusing area; according to each first lens running distance value, respectively running a lens and shooting a first picture; and selecting the corresponding first focusing area on each first picture, splicing the first focusing areas into a second picture and outputting the second picture to a display screen. According to the full-image focusing method provided by the invention, the full image is partitioned into a plurality of focusing areas, each first focusing area is respectively focused and the pictures are shot, and the pictures are cut to be spliced into the integral picture, so that each area of the full image is effectively focused.

Description

technical field [0001] The invention relates to imaging technology, in particular to a full-frame focusing method and a camera. Background technique [0002] The current camera focusing methods mainly include contrast focusing, phase focusing, and laser focusing. Contrast focusing drives the lens and continuously detects the contrast of the image to confirm whether the image is clear. If it is not clear, drive the lens to continue moving until a contrast peak is found. Phase focusing reserves some shaded pixels on the photosensitive element for phase detection, and determines the focus offset value through the distance between pixels and its changes to achieve accurate focusing. Laser focus obtains the focusing distance by emitting infrared light and receiving the bounced light. [0003] The focusing methods of the prior art can only focus on a partial area of ​​the entire picture, but in fact, the captured picture only has a unique depth of field in very few cases, so in m...
