Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0027] figure 1 It is a schematic flow chart of the multiple-exposure photographing method based on image synthesis in the present invention.

[0028] like figure 1 As shown, the multiple-exposure photographing method based on image synthesis includes:

[0029] S1, take a picture including foreground and background as a reference image;

[0030] S2, take the next picture containing the foreground and the background, a...

Abstract

The present invention discloses a multiple exposure shooting method and system based on picture synthesis. The method comprises: shooting a picture consisting of a foreground and a background, and taking the picture as an image; shooting the next picture consisting a foreground and a background, detecting the foreground of the next picture consisting of the foreground and the background based on the reference image, and performing synthesis of the detected foreground into the reference image; taking the foreground in the next picture consisting of the foreground and the background and the foreground in the reference image as the same object image with different positions in the space; and determining whether the number of the pictures consisting of the background and the foreground reaches the preset number of exposure or not, if the number of the pictures consisting of the background and the foreground reaches the preset number of exposure, outputting the reference image being subjected to synthesis at the last time, and if number of the pictures consisting of the background and the foreground does not reach the preset number of exposure, going on shooting and detection. The multiple exposure shooting method and system based on picture synthesis detect the partial contour of the picture having a brightness value being larger than a preset value and reduce the brightness values of all the pixels in the contour.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multiple-exposure photographing method and system based on image synthesis. Background technique [0002] At present, with the popularization of smart phones, many people like to take pictures with their mobile phones when they go out to play. Sometimes people want to get the effect of showing the same person in different positions on a photo. For this situation, The existing technology is to first take a photo containing only the scene as a template, then take other photos containing the scene and people, and then synthesize other photos containing the scene and people into the template to obtain The photo can show the effect of the same person in different positions. But the disadvantage of this approach is that you first need to take a photo with only a single scene as a template, and then you need to click pause after each photo is taken, and wait for the ...
