Abstract

A controller (101) designates whether images are integrated or not and image placement mode when integration is implemented. An image integrator (102) creates image data in a format designated by the presence/absence of integration and placement mode. A 3D information generator (103) generates 3D information necessary for 3D image display by formatting the presence/absence of integration and the placement mode. An encoder (104) encodes the image data created by image integrator (102) and generates coded data. A multiplexer (105) converts the encoded data generated by encoder (104) and the 3D information created by the 3D information generator into a predetermined format and outputs the result to the outside. This arrangement enables image data for 3D display to be versatile.

Claims

1. An image data generating apparatus for generating image data of a predetermined data format from a plurality of images corresponding to a plurality of viewpoints, comprising:

an information generating means for generating an integration information that indicates whether images from different viewpoints have been integrated into a single image or not and an image placement information that indicates a placement relationship of the images from the different viewpoints inside of the single integrated image when the images from the different viewpoints are integrated into the single image,

wherein the data format includes the integration information and the image placement information, and

the image placement information includes information on the placement relationship in which the viewpoint images we positioned by rotation of a predetermined angle, and a placement order information that indicates whether the images are arranged in an order of the viewpoints or in a reverse order of the viewpoints.

2. The image data generating apparatus according to claim 1, wherein the predetermined angle is one or plural among 0 degrees, 90 degrees clockwise, 180 degrees clockwise and 270 degrees clockwise.

3. The image data generating apparatus according to claim 1, wherein the image placement information includes a placement direction information that indicates whether the images are arranged vertically or horizontally.

4. The image data generating apparatus according to claim 1, wherein the image placement information is information on the placement relationship of the images in which placements of the viewpoint images are positioned by rotation of a predetermined angle, information on the placement relationship of the images in which positions of the images are inverted in a predetermined direction based on a positional relationship of the viewpoints, or information on a combined relationship of the two placement relationships.

5. The image data generating apparatus according to claim 4, wherein the predetermined angle is one or plural among 0 degrees, 90 degrees clockwise, 180 degrees clockwise and 270 degrees clockwise, and the predetermined direction is one or plural among a horizontal direction and a vertical direction.

6. An image data reproducing apparatus for reproducing a plurality of images corresponding to a plurality of viewpoints, from image data of a predetermined data format, comprising:

an analyzing means for analyzing the predetermined data format,

wherein the analyzing means analyzes an integration information that indicates whether images from different viewpoints have been integrated into a single image or not and an image placement information that indicates a placement relationship of the images from the different viewpoints inside of the single integrated image, and reproduces the plurality of images using the integration information and the image placement information, and

the image placement information includes information on the placement relationship in which the viewpoint images are positioned by rotation of a predetermined angle, and a placement order information that indicates whether the images are arranged in an order of the viewpoints or in a reverse order of the viewpoints.

7. The image data reproducing apparatus according to claim 6, wherein the predetermined angle is one or plural among 0 degrees, 90 degrees clockwise, 180 degrees clockwise and 270 degrees clockwise.

8. The image data reproducing apparatus according to claim 6, wherein the image placement information includes a placement direction information that indicates whether the images are arranged vertically or horizontally.

9. The image data reproducing apparatus according to claim 6, wherein the image placement information is information on the placement relationship of the images in which placements of the viewpoint images are positioned by rotation of a predetermined angle, information on the placement relationship of the images in which positions of the images are inverted in a predetermined direction based on a positional relationship of the viewpoints, or information on a combined relationship of the two placement relationships.

10. The image data reproducing apparatus according to claim 9, wherein the predetermined angle is one or plural among 0 degrees, 90 degrees clockwise, 180 degrees clockwise and 270 degrees clockwise, and the predetermined direction is one or plural among a horizontal direction and a vertical direction.
