Light painting shooting apparatus and method, and mobile terminal

Abstract

The invention provides a light painting shooting apparatus and method, and a mobile terminal. The method comprises the following steps: in a long exposure mode, collecting a first image through a first camera module in double camera modules, and meanwhile collecting a second image through a second camera module; when the first camera module collects the first image, determining a field depth of a light source track in the first image according to the first image and the second image; determining an actual track of a part exceeding a reference plane according to the field depth and the projection of the part exceeding the reference plane on the reference plane; and then, synthesizing the part not exceeding reference plane in the light source track with an actual track exceeding the light source track. By implementation of the light painting shooting apparatus and method provided by the invention, the influence of error track to the light painting is effectively avoided by the real-time correction of the light source track, thereby improving the light painting precision and reducing the possibility and time of post processing of the light painting.

Description

technical field [0001] The present invention relates to the field of photographing and photographing, and more specifically, to a light painting photographing device, method and mobile terminal. Background technique [0002] Light painting is to continuously collect the contents of the current scene in the long exposure mode of the camera, usually the moving trajectories of one or more light sources, and then these trajectories are imaged in the same image; in this way, you can use light to draw Various works, so light painting is also called the art of light. In the real light painting creation, the light painting creator first determines the subject and content of the light painting, such as what kind of graphics to draw. It should be noted that these graphics are flat, because the images are all flat content; then, by The painter, carrying the light source, makes the light source move according to a certain trajectory under the request of the creator in the long exposure...

Problems solved by technology

However, the actual movement is in the three-dimensional space after all, and its real trajectory must not be in the same plane. There will be more or less some light source trajectories beyond the range of the reference plane, and these trajectories beyond the range of the reference plane, What the camera collects is only its projection on the reference plane, not the real trajectory, which inevitably causes deviations between light painting creation and imagination, and affects the accuracy of light painting creation

In addition, in the production of existing light painting works, it is all completed by a single camera. Even if a terminal with dual cameras is used to make light painting works, only one of the cameras is used to complete all the shooting, and It does not involve the production of light painting works through dual cameras, and light painting generally needs to be carried out in a dark environment, so the lack of image quality caused by a single camera cannot be avoided
