  • Patent number: 10171753
    Abstract: A shooting method, a shooting device and a computer storage medium. The shooting method comprises: continuously collecting images; reading the collected images and identifying a light painting region in the currently read image; extracting the light painting region and superposing the light painting region on a foundation image at a corresponding position to perform image synthesis and generate a synthesized image, and using the synthesized image as the foundation image for the next time of image synthesis; capturing the synthesized image and performing coding processing on the captured synthesized image; and converting image data after the coding processing into video file after the shooting is completed.

  • Patent number: 10129488
    Abstract: A method for shooting a light-painting video and a mobile terminal. The method includes steps as follows. After shooting begins, light-painting images are continuously collected by means of a camera. The light-painting images are read at intervals, and a composite image is generated from a current light-painting image and a previously collected light-painting image. Composite images are captured, the captured composite images are video-encoded, and a light-painting video is generated from the video-encoded composite images.

  • Publication number: 20180109711
    Abstract: A method for overexposed photography is disclosed. The method includes: photographing an overexposed picture in which a target object is included with a preset overexposed photography parameter; acquiring image data of the target object from the overexposed picture; generating a composite picture according to the acquired image data of the target object with a preset standard overexposed picture as the background. The embodiment of the present invention further discloses an apparatus for overexposed photography. The embodiment of the present invention can realize to photograph a picture with a target object which is clear and is highlighted over background while only requiring to take one picture without the requirement of long time for the exposure photography, which is fast and highly efficient.
