  • Patent number: 8035683
    Abstract: When three-dimensional images are displayed on various display apparatuses, the images are displayed in a state that allows for stereoscopic vision even if the size of the display apparatus is large or even if the resolution of the display apparatus is low. The apparatus includes: a decision means for deciding based on the standard information contained in the control information whether the amount of parallax on the display screen when three-dimensional image data is displayed is greater than the amount of parallax on the optimal display apparatus for displaying the three-dimensional image data; and an image processing means for implementing an image process for changing the amount of parallax, and adjusts the amount of parallax of three-dimensional images in accordance with the ratio between the pitch between dots of the standard display apparatus for displaying three-dimensional images and the pitch between dots of an own terminal.

  • Patent number: 7889196
    Abstract: An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller (102) designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter (101) creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator (103) creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer (104) converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

  • Patent number: 7720308
    Abstract: Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.

  • Patent number: 7679616
    Abstract: An image data recording apparatus includes a three-dimensional display control information generation unit receiving a parameter indicating a condition for picking up a three-dimensional image, and encoding the parameter so as to generate image pick-up condition information, and a file generation unit generating a multimedia information file including both of the image pick-up condition information and three-dimensional image data or at least one of the three-dimensional image data and two-dimensional image data.

  • Publication number: 20090284584
    Abstract: To provide an image processing device which, when synthesizing an image into a 3D image, realizes image synthesis free from artifacts by taking parallax of 3D image into consideration, and suppresses deterioration of image quality at block encoding. An image processing device 1 receives a left-eye image obtained from the viewpoint corresponding to the left eye and a right-eye image obtained from the viewpoint corresponding to the right eye as input, determines the transparency of an object to be synthesized into the left-eye image and right-eye image by transparency determining means 3, based on the parallax information from a parallax detecting means 2 that detects parallax information and the positional information from a positioning means 5, and further determines the synthesized position of the object by an adjusting means 32 so that it aligns with the boundaries of encoding blocks, to thereby achieve synthesis of the object into the left-eye image and right-eye image.

  • Publication number: 20090263007
    Abstract: If horizontal viewpoint quantity information Nx and vertical viewpoint quantity information Ny are predetermined quantities, a value of the aspect ratio of the output image data to be finally output satisfies a predetermined condition, and a 3D identification mark is contained in the output image data, then an image recording device adds a first extension as general-purpose 3D image data which can also be used in a conventional device and records it. Accordingly, when 3D image data is output (displayed and printed) in a conventional device, image data which can be used as 3D image data (which can be viewed as a stereoscopic image) can be output as general-purpose image data while image data which cannot be used as 3D image data in the conventional device is not output as image data. This prevents a confusion of general users.
