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.

Claims

1. A stereoscopic image recording device for creating stereoscopic image data from image data corresponding to two or more different viewpoints and recording the same, comprising:

general-purpose stereoscopic image data judging means for judging whether the image data contained in the stereoscopic image data, out of created stereoscopic image data, is general-purpose stereoscopic image data or not; and

extension decision recording means for adding a first predetermined extension as an extension of the stereoscopic image data and recording the same when the general-purpose stereoscopic image data judging means judges that the stereoscopic image data is the general-purpose stereoscopic image data, and adding a second predetermined extension as the extension of the stereoscopic image data and recording the same when judged not to be the general-purpose stereoscopic image data.

2. The stereoscopic image recording device according to claim 1, wherein a condition of judging performed by the general-purpose stereoscopic image data judging means contains at least one of conditions:

whether a viewpoint quantity is 2 or not, whether an aspect ratio satisfies a predetermined condition or not, whether a horizontal to vertical ratio of image scaling satisfies a predetermined condition or not, and whether arrangement of the image satisfies a predetermined condition or not.

3. The stereoscopic image recording device according to claim 1, wherein the general-purpose stereoscopic image data judging means is further provided with mark judging means for judging to be the general-purpose stereoscopic image data, when the mark indicating the image for stereoscopic viewing is contained in the stereoscopic image data.

4. The stereoscopic image recording device according to claim 1, wherein the stereoscopic image data is recorded by setting the first predetermined extension as an extension of a JPEG image.

5. The stereoscopic image recording device according to claim 1, further comprising aspect ratio adjusting means for adjusting an aspect ratio of the stereoscopic image data to a predetermined aspect ratio, when the aspect ratio of the stereoscopic image data is other than the predetermined aspect ratio.

6. A program in a computer for creating stereoscopic image data from image data corresponding to two or more different viewpoints and recording the same, for realizing:

a general-purpose stereoscopic image data judging function for judging whether the stereoscopic image data is general-purpose stereoscopic image data in which a viewpoint quantity of the image data contained in the stereoscopic image data is two and an aspect ratio of the stereoscopic image data satisfies a predetermined condition or not, out of created stereoscopic image data; and

an extension decision recording function for adding a first predetermined extension as an extension of the stereoscopic image data and recording the same when the general-purpose stereoscopic image data judging function judges that the stereoscopic image data is the general-purpose stereoscopic image data, and adding a second predetermined extension as an extension of the stereoscopic image data and recording the same when judged not to be the general-purpose stereoscopic image data.
