Problems solved by technology

However, the existing multiple exposure methods can only superimpose the entire image, that is, the area exposed each time is the entire photo, and it is impossible to perform multiple exposures on parts
As a result, the space for users to freely create with the multiple exposure function is severely limited, resulting in poor user experience

[0031] see figure 1 , figure 2 , propose the first embodiment of the multiple exposure method of the present invention, the multiple exposure method includes the following steps:

[0032] Step S101 , displaying the composite effect of the existing picture and the real scene on the viewfinder preview interface.

[0033] The existing picture 10 may be a picture stored locally, or a picture formed just after exposure. The synthetic effect of the real scene 20 currently captured by the lens and the existing picture 10 is displayed in real time on the viewfinder preview interface. Such as figure 2 As shown, the leopard displayed in the viewfinder preview interface is the existing picture 10, and the desert is the real scene captured by the current lens 20. The user can preview the rendering of the combination of the leopard and the desert in real time. By viewing the preview rendering, even if there is no Ordinary users with shooting skills can also adjust the composition of ...

[0038] see in conjunction figure 2 , image 3 , propose the second embodiment of the multiple exposure method of the present invention, the multiple exposure method includes the following steps:

[0039] Step S201, displaying the composite effect of the existing picture and the real scene on the viewfinder preview interface.

[0040] Step S202, selecting at least two exposure areas on the framing preview interface.

[0041] This example is in figure 2 The shown viewfinder preview interface provides at least two exposure area selection frames 121, each exposure area selection frame 121 can be adjusted to a suitable position, and the size and shape of each exposure area selection frame 121 can also be adjusted, such as various geometric shape or outline shape of animals and plants etc. Finally, the ranges defined by each exposure area selection frame 121 are the selected exposure areas. The number of exposure areas can be pre-set, and can also be set or changed at any tim...

Abstract

The invention discloses a multiple exposure method and device. The multiple exposure method comprises the steps of displaying synthesis effect of an existing picture and a real scene on a view-taking preview interface; selecting an exposure area on the view-taking preview interface; and enabling the existing picture and the real scene in the exposure area to be synthesized into one picture. Accordingly, local multiple exposure is achieved, a free creation mode is provided for users, a multiple exposure creation space is expanded, and user experience is greatly improved.

Description

technical field [0001] The invention relates to the field of exposure technology, in particular to a multiple exposure method and device. Background technique [0002] The multiple exposure technique originated from film cameras, and it refers to the shooting technique of exposing multiple shots onto the same negative to achieve multiple image overlapping. Later, digital cameras took advantage of the characteristics of convenient processing of digital signals to inherit and develop the original multiple exposure. However, the existing multiple exposure methods can only superimpose the entire image, that is, the area exposed each time is the entire photo, and multiple exposures cannot be performed on parts. As a result, the space for users to freely create using the multiple exposure function is severely limited, resulting in poor user experience. Contents of the invention [0003] The main purpose of the present invention is to provide a multiple exposure method and devi...
