Embodiment 1

[0032] see figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the photographing method of the present invention. The method includes but not limited to the following steps.

[0033] Step S100, focusing on the object to be photographed and the background within the viewfinder range.

[0034] Before this step, the step of turning on the camera and taking a view may also be included. The detailed technical features of this step are within the comprehension scope of those skilled in the art, and will not be repeated here.

[0035] Wherein, the object to be photographed in step S100 may be a human face, a scene, or the like. The camera focuses on the subject and the background separately.

[0036] Step S110, respectively record the brightness value ranges in which the object to be photographed and the background have optimal exposure brightness during the focusing process.

[0037] In this step, the optimal exposure brightness of the object to be photo...

Embodiment 2

[0045] see figure 2 , figure 2 It is a schematic flowchart of the second embodiment of the photographing method of the present invention, and the photographing method in this embodiment includes but not limited to the following steps.

[0046] Step S200, respectively setting the brightness value ranges of the object to be photographed and the background having optimal exposure brightness.

[0047] In this step, the optimal exposure brightness of the object to be photographed and the background refers to the brightness value of the exposure brightness of the clearest picture respectively between the object to be photographed and the background during the two focusing processes, and the front and rear (i.e. positive and negative) of the brightness value ) a certain value range as the brightness value range of the object to be photographed and the background having the best exposure brightness.

[0048] For example, assuming that the best brightness value of the object to be ...

Abstract

The invention provides a photographing method and a photographing device. The photographing method comprises the steps of respectively focusing on an object to be shot in a viewing range and a background; respectively recording brightness value ranges of the object to be shot and the background with the best exposure brightness during a focusing process; selecting a brightness value in the overlapped range of the brightness value range of the object to be shot with the best exposure brightness and the brightness value range of the background with the best exposure brightness to serve as an optimized exposure brightness value for shooting the viewing range; and using the optimized exposure brightness value to take a photo of the viewing range. Compared with the prior art, the photographing method and the photographing device provided by the invention select the brightness value in the overlapped range of the brightness value range of the object to be shot with the best exposure brightness and the brightness value range of the background with the best exposure brightness to serve as the optimized exposure brightness value for shooting the viewing range to take the photo of the viewing range; the photographing exposure brightness with the best effect can be acquired, and clearness of the photo can be ensured.

Description

technical field [0001] The present invention relates to the technical field of a method for adjusting exposure brightness during a photographing process, in particular to a photographing method and a photographing device thereof. Background technique [0002] Cameras and mobile terminals with camera functions are currently commonly used camera devices. Taking mobile phones as an example, when we use mobile phones to take selfies, most of them use face auto-focusing methods. In this way, when there is a big difference in brightness between the background and the face, the camera automatically captures the face clearly, while the background is too bright or too dark. And when I manually focus, I found that the brightness of the background can be adjusted very clearly, but the face cannot be well represented. [0003] When shooting such scenes, we want to capture both the background and the characters clearly. But at present we can only choose one of the situations, that is, ...
