Method and device for implementing painting with light and shooting equipment

Abstract

The invention discloses a method and a device for implementing painting with light and shooting equipment. The method comprises the steps of: acquiring the pixel value of each pixel of each frame of shot image; for each pixel, calculating the pixel difference between the adjacent frames of image respectively; and according to the obtained pixel difference and a preset light source threshold, determining each pixel as a light source or a background pixel, and reducing the pixel values of the background pixels. By distinguishing the light sources from the background pixels and reducing the pixel values of the background pixels, the contrast effect of the locus of light and the background is increased, so that the background of the image becomes dark, the effect of night painting with light is realized in the scene of too strong light by day, the application scene of painting with light is expanded, and the user shooting experience is improved.

Description

technical field [0001] The present invention relates to field photography technology, in particular to a method, device and photographing equipment for realizing light painting photography. Background technique [0002] Light painting photography is a simple yet creative and surprising photography technique. Light painting photography needs at least two people to cooperate with each other to complete, so it is more varied and interesting. It is mainly a photographic art method that uses the movement of the light source to enhance the environment or the subject. The light source moves within a period of time, and the photosensitive element of the camera evenly records the light at each unit moment, thereby recording the light source movement track of the entire picture. Light painting photography can be done indoors, at night, and even in some dim light environments where it is impossible to take pictures at all. [0003] In order to highlight the expressive ability of lig...

Problems solved by technology

[0003] In order to highlight the expressive ability of light trajectory, at present, light painting photography needs to be carried out in scenes with low light. In scenes with relatively bright light, it is impossible to capture the effect of clear contrast of light trajectory.

That is to say, at present, the application scenarios of light painting photography are limited to night or dimly lit scenes, so if the user finds a good shooting scene in daytime or brightly lit scenes, it is impossible to record the light painting effect at that time, which will undoubtedly reduce the user shooting experience
