  • Patent number: 10027948
    Abstract: Camera related methods and apparatus which are well suited for use in capturing stereoscopic image data, e.g., pairs of left and right eye images, are described. Various features relate to a camera rig which can be used to mount multiple cameras at the same time. In some embodiments the camera rig includes 3 mounting locations corresponding to 3 different directions 120 degrees apart. One or more of the mounting locations may be used at a given time. When a single camera pair is used the rig can be rotated to capture images corresponding to the locations where a camera pair is not mounted. Static images from those locations can then be combined with images corresponding to the forward direction to generate a 360 degree view. Alternatively camera pairs or individual cameras can be included in each of the mounting locations to capture video in multiple directions.

  • Patent number: 8160440
    Abstract: A three-dimensional image pickup apparatus for capturing a three-dimensional image which includes a left-eye image and a right-eye image includes: a first imaging unit having a first optical system and operable to take the left-eye image; a second imaging unit having a second optical system and operable to take the right-eye image; and a controller operable to control the first imaging unit and the second imaging unit. The first optical system and the second optical system individually include a convergence angle changing unit capable of optically changing a convergence angle and a focal length changing unit capable of optically changing a focal length. The controller, when controlling the focal length changing unit to change the focal length, controls the convergence angle changing unit based on a predetermined constant convergence angle tracking curve to keep the convergence angle constant before and after the change of the focal length.

    Abstract: To enable satisfactory simultaneous and widely varied pictures to be obtained, for example, by allowing a common user to obtain an overall picture while the common user performing desired image capturing, or the like. A first image capturing device image-captures a subject to record this image, and also transmits a trigger signal to a second image capturing device. The second image capturing device image-captures an image to record this image in accordance with the trigger signal. Thus, the first and second image capturing devices enable both of an overall image and a zoomed image to be obtained with simultaneous timing.

    Abstract: An adapter for controlling a first camera and a second camera, which exhibit differing operating characteristics, in a three-dimension (3D) camera imaging system. The adapter provides a camera control signal to the first camera to control operation of the first camera. The adapter converts the camera control signal to a second camera control signal utilizing information from the first and the second cameras indicative of imaging states of the cameras, and provides the second camera control signal to the second camera to control operation of the second camera. The conversion compensates for the differing operating characteristics of the first and second cameras.
