Example Embodiment

[0085] 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 shooting subject (for example, Zhang San). When the shooting subject in the black-and-white camera is clear, the contour features of the shooting subject are extracted by a preset image edge extraction algorithm, and the image at this time is obtained. focal length; the color camera shoots according to the focal length to obtain a first image. The first image is the first image to be exposed in the multiple exposure.

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

Example Embodiment

[0092] Example 2

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

Example Embodiment

[0094] Example 3

[0095] The technical solution of Example 3 is applicable to the case of multiple exposures of different locations and different locations, and the mobile terminal includes a first photographing unit, a second photographing unit, and an overlapping unit. Wherein the mobile terminal has a camera.

[0096] The first photographing unit is used for automatic focusing. When the outline of an animal (for example, dog A) in the first image is clear, exposure is performed to obtain the first image, the outline information of dog A is extracted, and the outline of dog A is extracted. Information is saved. The first image is the first image to be exposed in the multiple exposure.

[0097] Move the mobile terminal to a different place, or when the position of the dog A moves greatly, obtain the shooting angle and / or the framing range of the second image, the second image that needs to be exposed in the multiple exposure of the second image.

[0098] The second photog...

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...
