    Abstract: Disclosed herein are methods, devices, and non-transitory computer readable media that relate to stereoscopic image creation. A camera captures an initial image at an initial position. A target displacement from the initial position is determined for a desired stereoscopic effect, and an instruction is provided that specifies a direction in which to move the camera from the initial position. While the camera is in motion, an estimated displacement from the initial position is calculated. When the estimated displacement corresponds to the target displacement, the camera automatically captures a candidate image. An acceptability analysis is performed to determine whether the candidate image has acceptable image quality and acceptable similarity to the initial image. If the candidate image passes the acceptability analysis, a stereoscopic image is created based on the initial and candidate images.

    Abstract: It is quite common for users to have both video and photo material that refer to the same event. Adding photos to home videos enriches the content. However, just adding still photos to a video sequence has a disturbing effect. The invention relates to a method to seamlessly integrate photos into the video by creating a virtual camera motion in the photo that is aligned with the estimated camera motion in the video. A synthesized video sequence is created by estimating a video camera motion in the video sequence at an insertion position in the video sequence at which the still photo is to be included, creating a virtual video sequence of sub frames of the still photo where the virtual video sequence has a virtual camera motion correlated to the video camera motion at the insertion position.

    Abstract: A method for generating stereoscopic images with retinal rivalry effects. The method includes retrieving primary eye images and alternate eye images from memory. These images are filmed from horizontally offset cameras but include the same content. The method continues with processing the alternate eye images to introduce retinal rivalry such as by including a set of frames that have differing content from a corresponding set of frames from the primary eye images. The differing content, for example, may include an object rendered for the alternate eye that was not rendered in the primary eye images. The method may further include editing the primary eye images by inserting a transition and then editing the alternate eye images to perform the transition (e.g., a dissolve or cut) at a temporally offset transition point such as several frames later to introduce frames that differ in content from one eye stream to the other.

  • Publication number: 20130321592
    Abstract: An apparatus, a method and a storage medium including a function to generate a stereoscopic image are described. According to one implementation, the imaging apparatus includes an imaging lens; a first driving section; an obtaining section and a generating section. The first driving section rotates the imaging lens around an axis along a first direction orthogonal to an optical axis. The obtaining section obtains two image signals corresponding to two optical images which pass through the imaging lens rotated in two states to make a direction of the optical axis relatively different so that a relationship of a position of background with respect to a subject is different. The generating section generates image data of a stereoscopic image based on the two image signals.

    Abstract: An image capture device has an image capture module and a controller. The image capture module is used for capturing a plurality of consecutive preview images under an automatic shot mode. In addition, the image capture module can be a multi-view image capture module, which is used to capture a plurality of multiple-angle preview images. The controller is used for analyzing the preview images to identify an image capture quality metric index, and determining if a target image capture condition is met by referring to at least the image capture quality metric index. A captured image for the automatic shot mode is stored when the controller determines that the target image capture condition is met.

  • Patent number: 8581965
    Abstract: A means for 3D imaging takes two plane pictures of an object in different angles and respectively projects the correspondent images of the object toward users' eyes. Accordingly, the visual data would be transmitted to user's brain and integrated to construct a solid vision. A facility for 3D imaging comprises a multiple image projector consisting of a displaying unit installed on a refracting unit. Wherein, the displaying unit performs a plurality of images, and the refracting unit adopts an optical unit. Thereby, image beams generated by the displaying unit would travel through the refracting unit and deflect by a certain angle. Accordingly, the images shot from two different angles would be respectively projected into user's eyes, and a solid vision could be constructed.

  • Publication number: 20130293686
    Abstract: A mobile device generates a 3D reconstruction of a human subject by capturing a video frame sequence of the human subject. A pre-generated marker, which may be reticle or a 3D model of a humanoid, is displayed on the display while capturing the video frame sequence. The human subject is also displayed and the mobile device is held to cause the human subject to be displayed coincidently with the pre-generated marker. The video frame sequence that is captured while the mobile device is held to cause the human subject to be displayed coincidently with the pre-generated marker is used to generate a 3D reconstruction of the human subject, which may then be stored and transmitted to a remote server if desired. Sensors may be used to determine the pose of the mobile device with respect to the human subject, which may then be used to adjust the pre-generated marker appropriately.

  • Publication number: 20130222555
    Abstract: A reconstructed image which further reflects the photo shooting information of a main object is generated. A layer determiner defines a layer of a reconstructed image. A layer image generator reconstructs an image of an object included in the allocated depth range from a light field image and the depth map of the light field image for each layer. A conversion pixel extractor extracts corresponding pixels on a conversion layer which corresponds to an object to be modified. The object to be modified is designated by an operation acquired by a modification operation acquirer. A reconstructed image generator converts layer images using a conversion matrix defined by a conversion matrix determiner and generates an image whose composition has been modified by superimposing the layer images.

  • Patent number: 8514268
    Abstract: A method and device for high-resolution three-dimensional (3-D) imaging which obtains camera pose using defocusing is disclosed. The device comprises a lens obstructed by a mask having two sets of apertures. The first set of apertures produces a plurality of defocused images of the object, which are used to obtain camera pose. The second set of optical filters produces a plurality of defocused images of a projected pattern of markers on the object. The images produced by the second set of apertures are differentiable from the images used to determine pose, and are used to construct a detailed 3-D image of the object. Using the known change in camera pose between captured images, the 3-D images produced can be overlaid to produce a high-resolution 3-D image of the object.

  • Publication number: 20130201301
    Abstract: Disclosed herein are methods, devices, and non-transitory computer readable media that relate to stereoscopic image creation. A camera captures an initial image at an initial position. A target displacement from the initial position is determined for a desired stereoscopic effect, and an instruction is provided that specifies a direction in which to move the camera from the initial position. While the camera is in motion, an estimated displacement from the initial position is calculated. When the estimated displacement corresponds to the target displacement, the camera automatically captures a candidate image. An acceptability analysis is performed to determine whether the candidate image has acceptable image quality and acceptable similarity to the initial image. If the candidate image passes the acceptability analysis, a stereoscopic image is created based on the initial and candidate images.
