Abstract:
3-dimensional image data (400) recorded or transmitted includes 3-dimensional image identification information (401) showing that there exists data relating to a 3-dimensional image. Version information (402), for example, is version "1" containing as control information (403) only the parameter for identifying the image data structure such as parallax barrier method and the lenticular method and version "2" further containing a parameter specifying the parallax amount as the control information (403). Thus, for example, a reproduction apparatus having no parallax amount adjustment function can perform 3-dimensional display if the version is "1" but cannot perform display according to the specified parameter if the version is "2", which can be judged without analyzing the control information (403). Moreover, it is possible to provide profile information (801) for setting parameter values such as the number of viewpoints and the reduction ratio .
Abstract:
3-dimensional control information is created for 3-dimensional display of a main image. By multiplexing the main image, a thumbnail image, and the 3-dimensional control information, it is possible to output the thumbnail image for appropriately checking the image content when the main image is a 3-dimensional image. Moreover, it is judged whether the parallax amount of the 3-dimensional image is within the parallax range which can be viewed 3-dimensionally. If 3-dimensional view is impossible, an alarm is issued to a user and the parallax amount of the 3-dimensional image can be adjusted. Furthermore, when enlarging or contracting the 3-dimensional image, it is judged whether the parallax amount of the 3-dimensional image is within a parallax range which can be viewed 3-dimensionally. When the 3-dimensional view is difficult, the parallax can be adjusted.
Abstract:
An image data recording device (100) includes a 3-dimensional display control information creation section (11) for inputting a parameter indicating a condition when imaging a 3-dimensional image, encoding the parameter, and creating imaging condition information and a file creation section (12) for creating a multi-media information file containing both of the imaging condition information and the 3-dimensional image data or at least one of the 3-dimensional image data and the 2-dimensional image data.
Abstract:
A multimedia information file including 3-demensional image data is added by 3-dimensional display control information (2) indicating which 3-dimensional display method is assumed for the 3-dimensional image data or which data format is used for recording the data. A 3-dimensional image reproduction device displays the 3-dimensional image data after performing an appropriate conversion according to the data characteristic obtained from the 3-dimensional display control information (2), so that the recorded 3-dimensional image data (3) can have a general purpose and the same 3-dimensional image data can be utilized for different 3-dimensional display methods.
Abstract:
An image input from an image input unit (1) is displayed on a display unit (4) and transmitted to an object extraction unit (2). An initial contour setting unit (5) sets a graphic of a predetermined size at a predetermined position on the screen and the display unit (4) superimposes the graphic on the input image to be displayed. The initial contour can be moved vertically and horizontally by a moving unit (6) and can be magnified/demagnified by a magnification/demagnification unit (7). When the initial contour is moved to a desired position and has a desired size, the contour is confirmed as the initial contour to be used for an object extraction by a decision unit (8). In the object extraction unit (2), an object is extracted by using the input image and the initial contour. The object extracted is recorded onto a recording medium by recording/reproducing unit (3). When this is reproduced, it is displayed on the display unit (4). Thus, it is possible to rapidly set an initial contour by a simple operation without providing a particular input device.
