Mobile terminal and photographing method thereof

Abstract

The invention discloses a mobile terminal. After an obtaining module detects a lightpainting photographing instruction triggered by a user, an image obtained currently in a photographing view-finding frame is set to be a background image; a determination module determines a light source for lightpainting photographing in the view-finding frame, wherein the view-finding frame moves relative to the light source; a collection module collects images, relative to all positions of the view-finding frame, of the light source at a preset time interval; and a synthesis module splices the collected images, relative to all positions of the view-finding frame, of the light source into a moving track image of the light source and carries out synthesis on the moving track image of the light source and the background image to obtain a lightpainting image. In addition, the invention also discloses a photographing method. Therefore, under the circumstance that the light source is kept to be still, the view-finding frame moves to obtain the moving track image of the light source relative to the view-finding frame, so that a technical problem that the still light source can not be used for carrying out lightpainting photographing in the prior art can be solved and the using satisfaction degree of the user increases.

Description

technical field [0001] The present invention relates to the technical field of photographing, in particular to a mobile terminal and a photographing method thereof. Background technique [0002] At present, with the rapid development of mobile terminals such as mobile phones and tablet computers, the shooting functions of mobile terminals are becoming more and more diversified. Users all hope to take the most unique photos to show their friends, such as taking light painting photos. At present, light painting photos taken by mobile terminals generally need to prepare light sources for light painting photos in advance, such as flashlights, fluorescent sticks, etc., and then keep the position of the mobile terminal unchanged, move the light source continuously, and capture the moving track of the light source. A photo of the light painting showing the traces of the light source is obtained. However, for stationary light sources, such as street lamps, lighting lamps, etc., use...
