Embodiment Construction

[0026] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings required in the embodiments of the present invention. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort.

[0027] In order to facilitate the understanding of the embodiments of the present invention, some content involved in the embodiments of the present invention will be described first.

[0028] Among them, the zigzag HDR (zzHDR) technology is the latest HDR technology, which supports exposure from the photosensitive unit to improve the dynamic range of the captured image. The exposure of zzHDR includes long exposure and short exposure. An image is divided into two images with different exposure parameters. When the...

Abstract

The invention provides an image shooting method and a mobile terminal; the image shooting method comprises the following steps: receiving a shooting order, and detecting whether automatic exposures a main camera lens and an auxiliary camera lens are in a synchronization state; if yes, respectively obtaining the first image data taken by the main camera lens and the second image data taken by the auxiliary camera lens; combining the first and second image data so as to obtain a synthesis image. The method can use a zzHDR function to improve the dynamic scope of the final synthesis image, thus preventing the poor synthesis image dynamic scope effects caused by time differences and jittering hands, obtaining the high dynamic scope image with a good dynamic scope effect, and using the dual-camera lens to reduce the synthesis image sharpness loss to the lowest level.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an image capturing method and a mobile terminal. Background technique [0002] With the development of terminal technology, terminal cameras have become a basic standard configuration of mobile terminals, such as mobile phones, laptops, wearable devices, etc. While bringing great convenience, users have more and more demand for taking pictures. [0003] At present, most terminal cameras support a high dynamic range (High Dynamic Range, HDR) camera mode. Compared with ordinary images, HDR images can provide more dynamic range and image details. According to the low dynamic range (Low Dynamic Range, LDR) images of different exposure times, the LDR images corresponding to the best details of each exposure time are used to Synthesize the final HDR image, which can better reflect the visual effect of people in the real environment. [0004] In order to obtain HDR i...
