  • Patent number: 8717419
    Abstract: An image processing apparatus executes a distortion correction on coordinates of a target pixel in a virtual viewpoint image based on distortion characteristics of a virtual camera and calculates coordinates in the virtual viewpoint image after the distortion correction. The image process apparatus calculates ideal coordinates in a captured image from the coordinates in the virtual viewpoint image after the distortion correction and calculates real coordinates in the captured image from the ideal coordinates in the captured image based on distortion characteristics of an imaging unit. The image process apparatus calculates a pixel value corresponding to the real coordinates from image data of the virtual viewpoint image and corrects the pixel value corresponding to the real coordinates based on ambient light amount decrease characteristics of the imaging unit and ambient light amount decrease characteristics of the virtual camera.

  • Patent number: 8705799
    Abstract: The path and/or position of an object is tracked using two or more cameras which run asynchronously so there is need to provide a common timing signal to each camera. Captured images are analyzed to detect a position of the object in the image. Equations of motion for the object are then solved based on the detected positions and a transformation which relates the detected positions to a desired coordinate system in which the path is to be described. The position of an object can also be determined from a position which meets a distance metric relative to lines of position from three or more images. The images can be enhanced to depict the path and/or position of the object as a graphical element. Further, statistics such as maximum object speed and distance traveled can be obtained. Applications include tracking the position of a game object at a sports event.

    Abstract: Systems and methods for 2D image and spatial data capture for 3D stereo imaging are disclosed. The system utilizes a cinematography camera and at least one reference or “witness” camera spaced apart from the cinematography camera at a distance much greater that the interocular separation to capture 2D images over an overlapping volume associated with a scene having one or more objects. The captured image data is post-processed to create a depth map, and a point cloud is created form the depth map. The robustness of the depth map and the point cloud allows for dual virtual cameras to be placed substantially arbitrarily in the resulting virtual 3D space, which greatly simplifies the addition of computer-generated graphics, animation and other special effects in cinemagraphic post-processing.

A face detecting section detects persons' faces from a preliminary image captured by each imaging unit. A face comparing section compares the faces between the two preliminary images. A face evaluating section calculates a face evaluation value of each face, and determines ranking of the faces in each preliminary image based on the face evaluation values. Moreover, in consideration of the ranking of the faces determined in the telephoto preliminary image out of the two preliminary images, the face evaluating section corrects the face evaluation values and ranking of the faces in the wide-angle preliminary image. In each imaging unit, photographic conditions for actual photography are determined with giving high priority to the higher-ranked image.

In various embodiments of the present invention, information is signaled to a decoder that slices are coded using certain constraints, so that parallel decoding of slices is possible. This signaling can be performed at a sequence parameter set level, or it could be performed at picture parameter set level, slice header level or macroblock header level. Additionally, the delay between various views is also signaled to the decoder, at the same location as the constraint information in various embodiments. Various algorithms can also be used to improve the coding efficiency of the system.

    Abstract: A remote control device is used to control a mechanism with the aid of a movement pattern and/or a distance pattern of at least one moved object. The remote control device has a camera module to receive a stereo image and to detect the moved object. An image evaluation module has a movement evaluation sub-module and a distance evaluation sub-module. A control and communication module of the remote control device, depending on the movement or distance values determined, generates at least one mechanism control signal and sends it to the mechanism to be controlled. An interface module has a data memory, a comparator sub-module and a communication sub-module. The latter, with adequate agreement between the respective actual parameter and one of the desired movement parameters, sends the control signal assigned in the table to the module of the remote control device or to the mechanism.

    Abstract: A depth acquisition system utilizes at least three sensors with at least one sensor in a non-colinear configuration to increase depth information. This configuration provides both vertical and horizontal depth information to be combined to enhance image quality, especially in three-dimensional image gathering. Vertical sensor pairs aid in determining disparities for horizontal edges and make depth estimations for horizontal edges more accurate.

  • Patent number: 8547443
    Abstract: High dynamic range imaging includes creating a high dynamic range image file for a subject image captured from a first angle. The high dynamic range image file is created by an image capturing device and is stored on the image capturing device. High dynamic range imaging also includes receiving, at the image capturing device over a communications network, a second high dynamic range image file for the subject image captured from a second angle. The second high dynamic range image file is subject to an authorization requirement. High dynamic range imaging further includes creating, by the image capturing device, a composite high dynamic range image file by combining elements of both of the high dynamic range image files, and generating, by the first image capturing device, a three-dimensional high dynamic range image from the composite high dynamic range image file.

  • Patent number: 8504640
    Abstract: A method of providing three dimensional (3D) information is disclosed in which a master recruits a local slave to provide contemporaneous images. The images are collected and 3D information extracted therefrom. The 3D information or various images may be transmitted to a remote device and is employed to provide a substitute background that replaces the background of the original image. Either the new image is displayed on one or both devices. The images can be collected and the 3D information extracted at either of the master or slave or at a separate device. To recruit the slave, the master broadcasts a query to all local devices, determines the available devices and their characteristics, automatically or manually selects a particular device, requests authorization from the selected device, and pairs with the selected device when authorization is received. Devices of the same or different types may be paired.
