example 1

[0086] The mobile terminal of Example 1 includes a first photographing unit, a second photographing unit, and an overlapping unit. Wherein the mobile terminal has a black and white camera and a color camera.

[0087] The first shooting unit is used to focus on the subject (such as Zhang San), and when the subject in the black and white camera is clear, extract the outline features of the subject through a preset image edge extraction algorithm, and obtain focal length; the color camera shoots according to the focal length to obtain a first image. Wherein, the first image is the first image to be exposed in the multiple exposure.

[0088] When the position of the mobile terminal is moved in the same place, or when the position of Zhang San is slightly moved, the shooting angle and / or viewfinder range of the second image is obtained, and the second image needs to be exposed in multiple exposures of the second image.

[0089]The second shooting unit is configured to determine Z...

example 2

[0093] The only difference between Example 2 and Example 1 is that Zhang San's face is used as the subject in Example 2.

example 3

[0095] The technical solution of Example 3 is applicable to multiple exposures of the same scene in different places and different scenes in different places. The mobile terminal includes a first shooting unit, a second shooting unit, and an overlapping unit. Wherein the mobile terminal has a camera.

[0096] The first photographing unit is used for auto-focusing. When the outline of a certain animal (such as dog A) in the first image is clear, exposure is performed to obtain the first image, and the outline information of dog A is extracted, and the outline of dog A is extracted. The information is saved. Wherein, the first image is the first image to be exposed in the multiple exposure.

[0097] When the mobile terminal is moved to a different place, or when the position of the dog A is greatly moved, the shooting angle and / or viewfinder range of the second image is obtained, and the second image needs to be exposed in multiple exposures of the second image.

Abstract

The invention discloses a mobile terminal and a multi-exposure shooting method. A first shooting unit of the mobile terminal is used for shooting a first image, wherein feature information of a shooting subject in the first image is recorded while the first image is shot; a second shooting unit is used for determining the shooting subject of a successively shot image according to the feature information of the shooting subject in the first image and shooting the image; and a superposition unit is used for carrying out synthetic processing on the first image and the successively shot image according to a multi-exposure shooting mode to obtain a multi-exposure image. The shooting subjects in all to-be-exposed images in multi-exposure can be accurately focused through shooting the first image, recording the feature information of the shooting subject in the first image while shooting the first image and determining the shooting subject of the successively shot image by using the feature information of the shooting subject; and the multi-exposure image which is clear in picture and relatively good in visual effect is obtained through superposition.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a multiple exposure shooting method thereof. Background technique [0002] Multiple exposure is a technical method in photography that uses two or more independent exposures and then overlaps them to form a single photo. It can also be called multiple exposures, because the parameters of each exposure are different. , so the final photo will have a unique visual effect. The types of multiple exposures include the following: 1. Multiple exposures of the same scene in the same place and different scenes in the same place; 2. Multiple exposures of the same scene in different places and different scenes in different places; 3. All real focus shooting and virtual focus and real focus shooting 4. Multiple exposures with thick and light and multiple zooms; 5. Multiple exposures with and without background, etc. [0003] Multiple exposures of the same scene...
