  • Multi-camera time slice system and method of generating integrated subject, foreground and background time slice images
    Patent number: 10244220
    Abstract: A multi-camera time slice system and method of producing a three-dimensional (3D) integrated time slice image array uses multiple cameras to capture a subject to produce an array of subject images with transparent backgrounds. The array of subject images with transparent backgrounds is merged with an array of foreground images with transparent backgrounds and an array of background images, which are captured in a similar manner as the array of subject images, to produce the 3D integrated time slice image array.
    Type: Grant

  • Multi-camera system and method of calibrating the multi-camera system
    Patent number: 9066024
    Abstract: A multi-camera system and method of calibrating the multi-camera system uses at least one timer to synchronize cameras of the multi-camera system with respect to time. The cameras are used to capture images of the at least one timer. The images are then analyzed to adjust an image-capture timing parameter of at least one of the cameras to time synchronize the cameras.
