Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In some photo scenes, there are often both strong light areas and low light areas within the viewfinder range. When taking a photo, the default focus point and metering point are often located in the center of the picture or in a specific area, so when taking a photo based on a low-light area, the background part will be overexposed, making it impossible to distinguish details in the photo.

[0026] For example, when taking a selfie, if the back...

Abstract

The invention discloses a photographing method, device and mobile terminal. The method includes: after receiving a photographing instruction, identifying a target area in the photographing area; determining a photometry point to perform photometry in the target area, and taking a photo Obtain the first image; determine the photometering point in the non-target area to perform photometry, and take a photo to obtain the second image, the brightness difference between the target area and the non-target area is greater than the set threshold; the first The image of the target area in the first image is spliced ​​and synthesized with the image of the non-target area in the second image to obtain a third image as a photo. In the third image stitched together, the images of the target area and the non-target area have been metered separately, which can ensure that the brightness of the photo is normal, and there will be no over-exposure or over-darkness. Compared with the existing technology As a result, the quality of the photos has been improved.

Description

technical field [0001] The present invention relates to the communication field / terminal field, and in particular to a photographing method, device and mobile terminal. Background technique [0002] With the popularization of digital products, more and more digital devices have a camera function. In some photo scenes, there are often both strong light areas and low light areas within the viewfinder range. [0003] When taking pictures based on the low-light area, the light-metering algorithm will try to make the brightness of the objects in the low-light area reach a normal level, while the strong-light area may be overexposed, so that it is impossible to distinguish the brightness of the photo in the strong-light area. Details, the resulting photo quality is not high. Contents of the invention [0004] An embodiment of the present invention provides a photographing method to solve the problem that the photos obtained by the existing photographing method may be overexplo...
