Problems solved by technology

However, this synthesis method cannot determine the subject in the image, and treats the subject as ordinary pixels, which leads to blurring and distortion of the subject in the composite image, and the shooting effect is not good.

[0037] See figure 1 , The first embodiment of the multiple exposure method of the present invention is proposed. The multiple exposure method includes the following steps:

[0038] Step S101, aiming at a scene and shooting a background image.

[0039] The camera device enters the multiple exposure shooting mode, and the first photo taken is the background image by default. Randomly select a favorite scene to shoot and get a background image (such as figure 2 Shown), there is no subject that the user wants in the background image.

[0040] Step S102: Place a shooting subject in the scene, and shoot a contrast image.

[0041] Keep the camera device still, and lock its metering, focus and other parameters that are likely to cause changes in the viewfinder. 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 will take a manual shot. One or more contrast images (e.g. image 3 Shown). The number of contrast images ...

[0051] See Figure 7 , A second embodiment of the multiple exposure method of the present invention is proposed. The multiple exposure method includes the following steps:

[0052] Step S201, aiming at a scene and shooting a background image.

[0053] Step S202: When the shooting subject enters the scene and moves in the scene, continuously shoot multiple contrast images.

[0054] The subject of this embodiment is a moving object. After the user finishes taking the background image, he keeps the camera device still, and locks its metering, focusing and other parameters that may easily change the viewfinder. When the subject moves into the scene, once The user presses the shooting button, and the camera device automatically continuously shoots multiple contrast images, and each contrast image captures the motion state of the subject at different moments. The number of contrast images taken is preset by the user.

[0055] Step S203: Compare the background image with each contrast 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 present invention relates to the field of imaging technology, in particular to a multiple exposure method and imaging device. Background technique [0002] Multiple exposure in a digital camera is actually a process of combining multiple photos into one photo in real time through a certain method. The existing multiple exposure methods mainly use the pixel characteristics of the image to make judgments, for example, by adding the values ​​of the corresponding pixels of the two images in a certain ratio for synthesis. However, this synthesis method cannot determine the subject in the image, and treats the subject as ordinary pixels for processing, which results in blurring and distortion of the subject in the composite image, and poor shooting effect. Summary of the invention [0003] The main purpose of the present invention is to provide a multiple exposure method and camera device, aiming to improve the shooting effect of multiple exposure. [0004] To...
