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-screen focusing method and a camera. The full-screen focusing method includes the following steps: dividing the full screen into a plurality of first focusing areas according to predetermined rules; focusing on each of the first focusing areas to obtain The first lens of each first focus area needs to run the distance value; Run the lens and take the first photo respectively according to each described first lens needs to run the distance value; Select the corresponding first focus area on each first photo, and each A focus area is stitched into a second photo and output to the display screen. The full-frame focusing method provided by the present invention divides the whole frame into a plurality of first focus areas, each of the first focus areas respectively focuses and takes pictures, and cuts these pictures to form the whole picture, so that each area of ​​the full picture have been 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...
