Abstract

The invention relates to an image processing technology, and especially relates to a method for enhancing a light painting effect in a background image, and a device for realizing the method. The method for providing the light painting effect, provided by one embodiment of the invention, comprises the following steps: receiving motion data of an object, the motion data relating deceleration of the object at each time and being obtained by a sensor arranged on the object; according to the motion data, determining a motion path of the object; according to light source attribute which the object is endowed with, generating a motion image of the object from the determined motion path; and synthesizing the motion image and the background image. Since a light source locus is recorded by use of the sensor arranged on the object, a high-performance camera and optimization arrangement of shooting parameters are unnecessary.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method for adding a light painting effect to a background picture and a device for realizing the method. Background technique [0002] The so-called "light painting photography" refers to a photography method that uses long-time exposure to create special image effects through light source changes during the exposure process (for example, using moving light sources to "draw" images in the dark). [0003] The typical production process of light painting photography generally includes the following steps. The first is to choose a venue with sufficiently dark light as the background venue for shooting light painting effects, such as underground garages, open spaces at night, etc. Then choose a portable light source as the "brush" used in light painting, and you can use light sources with various characteristics, such as LED lights, flashlights, fireworks and torches. The camer...
