Abstract

The embodiment of the invention provides a secondary exposure photographing method and apparatus for an electronic device. The method comprises the following steps: operating a photographing mode of the electronic device; receiving a first photographing instruction; synthesizing first frame of exposure image data collected by a camera module at a first preset proportion with each frame of exposure image data collected by the camera module in real time at a second preset proportion in real time according to a secondary exposure algorithm, and displaying the synthetic exposure image data on a photographing preview interface; receiving a second photographing instruction; synthesizing the first frame of exposure image data at the first preset proportion with a second frame of exposure image data collected by the camera module at the second preset proportion according to the secondary exposure algorithm, and generating a compression encoding picture according to the synthetic exposure image data. By implementing the secondary exposure photographing method and apparatus provided by the embodiment of the invention, the secondary exposure effect is directly displayed on the photographing preview interface and foliation, the proportion of the secondary exposure in the foliation can be freely set, and no loss of the picture pixels and the preview smoothness can be maximally guaranteed.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method and device for secondary exposure and photographing of electronic equipment. Background technique [0002] Double exposure technology is a unique photography technology in the era of film cameras. Its principle is to expose the same film twice or more times (multiple exposures), so as to present the effect of superimposing two scenes on one photo. [0003] Cameras are now a standard feature on smartphones, but there is currently no mature solution for adding double exposure effects to a phone's camera app. If the user wants to add a second exposure effect to the photo, they can only use post-processing software such as PhotoShop (an image processing software) to perform the second exposure process, which is very inefficient, and the quality of the photo will be lost to a certain extent, and the user experience is poor. . Contents of the invention ...
