  • Publication number: 20170076428
    Abstract: Provided is an information processing apparatus configured to improve visibility for a user when presentation information is projected and displayed on a target object. The information processing apparatus includes an image capture device and a display device. The information processing apparatus recognizes marker IDs and positions of markers included in a captured image obtained via the image capture device, and determines whether or not one or more markers are included in the captured image (Step S203). When one or more markers are included in the captured image (Step S203: Y), a related information acquisition unit acquires related information corresponding to the marker IDs (Step S204). At this stage, a distance between the information processing apparatus and each marker is calculated based on a size of the markers included in the image (Step S212).

  • Patent number: 9460537
    Abstract: An apparatus designs an animation expressing a transition of display forms of an object. A reception unit receives an operation for setting key frames in the animation at one or more time points on a time axis displayed on a screen, the time axis corresponding to the animation, and instructs a display form of the object at each of the set key frames. The reception unit receives, in a state when one or more key frames are set on the time axis and a display form of the object is instructed at each of the set key frames, an instruction for reflecting a display form of the object instructed to a first key frame of an already set one or more key frames as a display form of the object at a second key frame set on the time axis. A display control unit displays indicators representing the key frames.
