Abstract

The present invention provides a photographing method. The photographing method comprises entering into a slow shutter photographing mode after acquiring a slow shutter photographing mode command; continuously acquiring images of all frames of a photographed object; dividing the image of each frame of the photographed object into an optical track area, a background light source area and a non light source area according to a first preset brightness value; synthesizing the optical track areas of the images of all the frames to be an optical track area of an object image; using background light source areas of images of one or more frames as a background light source area of the object image, so as to prevent the background light source area of the object image from over exposure; synthesizing the non light source areas of the images of one or more frames to serve as a non light source area of the object image, so as to enable the brightness of the non light source area of the object image to be enhanced and avoid over exposure; and storing the object image after acquiring a photographing command.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a photographing device and method. Background technique [0002] With the development of image processing technology and mobile terminal equipment, mobile devices are used as camera devices anytime and anywhere and have become an important function that is often used in daily life. People use camera devices to conveniently record beautiful moments and use them to express emotion. At present, most photographing devices (such as desktop computers, mobile phones, tablet computers, cameras, etc.) provide a photographing function. [0003] Users hope that the photos taken by taking pictures can effectively express the movement trajectory of the user's light source, such as the light track pattern formed after the hand-held light source moves, the fireworks performance that is easy to disappear and cannot be grasped, and the magnificent waterfall forming a silk-like e...
