[0037] see figure 1 , propose the first embodiment of the multiple exposure method of the present invention, the multiple exposure method includes the following steps:
[0038] Step S101, aligning with a scene, and shooting a background image.
[0039] The camera device enters the multiple exposure shooting mode, and the first photo taken by default is the background image. Randomly select a favorite scene to shoot, and obtain a background image (such as figure 2 shown), there is no subject in the background image that the user intended.
[0040] Step S102, placing a shooting subject in the scene, and shooting a comparison image.
[0041] Keep the camera device still, and lock its metering, focusing and other parameters that may easily lead to changes in framing, place the subject (such as an object) into the scene or let the subject (such as a person) enter the scene, and then the user manually takes a picture. one or more comparison images (such as image 3 shown).

[0051] see Figure 7 , propose the second embodiment of the multiple exposure method of the present invention, the multiple exposure method includes the following steps:
[0052] Step S201, aligning with a scene, and shooting a background image.
[0053] Step S202, when the subject enters the scene and moves in the scene, continuously shoot a plurality of comparison images.
[0054] The subject of this embodiment is a moving object. After the user shoots the background image, keep the camera device still, and lock its metering, focusing and other parameters that are likely to cause changes in the framing. When the subject moves into the scene, once When the user presses the shooting button, the camera will automatically shoot multiple comparison images continuously, and each comparison image captures the movement state of the subject at different moments. The number of photographed comparison images is preset by the user.
[0055] Step S203 , comparing the background image ...

Abstract
The invention discloses a multiple exposure method and a camera shooting device. The multiple exposure method includes the steps of obtaining a background image and a comparison image, comparing the background image with the comparison image, recognizing a shot subject from the comparison image and compounding the recognized shot subject into the background image, wherein the image of the shot subject is added to the background image to form the comparison image. Due to the fact that the shot subject is compounded into the background image and compounding is not conducted through a method of adding the whole comparison image to the background image according to a certain proportion, the shot subject can has fidelity and be displayed in a highlighted mode in the final compounded image, and the camera shooting effect of multiple exposure is improved.
Description
technical field [0001] The invention relates to the technical field of imaging, in particular to a multiple exposure method and an imaging device. Background technique [0002] Multiple exposure in digital cameras is actually a process of synthesizing multiple photos into one photo in real time through a certain method. The existing multiple exposure methods mainly use the pixel features of the images to make judgments, for example, by adding the values of the corresponding pixel points of the two images in a certain ratio to synthesize. However, in this synthesis method, the subject in the image cannot be judged, and the subject is treated as an ordinary pixel, which leads to the blurring and distortion of the subject in the composite image, and the shooting effect is not good. Contents of the invention [0003] The main purpose of the present invention is to provide a multiple exposure method and an imaging device, aiming at improving the shooting effect of multiple e...
