Abstract

The image display system includes a first image producer producing a first left-eye display image using a left-eye original image that is a left-eye captured image or a left-eye processed image produced therefrom, and producing a first right-eye display image using a right-eye original image that is a right-eye captured image or a right-eye processed image produced therefrom. A first image display unit allows left and right eyes of a viewer to view the first left-eye and right-eye display images. The first image producer produces the first left-eye and right-eye display images each corresponding to an image of a partial area of the original image. A second image producer produces, using at least one of the left-eye and right-eye original images, a second display image corresponding to an image of an area including the above partial area and being wider than that partial area.

Claims

1. An image display system comprising:

a left-eye image capturer and a right-eye image capturer respectively configured to acquire, by image capturing, a left-eye captured image and a right-eye captured image;

a first image producer configured to (a) produce a first left-eye display image using a left-eye original image that is the left-eye captured image or a left-eye processed image produced by image processing performed on the left-eye captured image, and (b) produce a first right-eye display image using a right-eye original image that is the right-eye captured image or a right-eye processed image produced by the image processing performed on the right-eye captured image; and

a first image display unit configured to allow a left eye and a right eye of a first viewer to view the first left-eye display image and the first right-eye display image,

wherein;

the first image producer is configured to produce the first left-eye display image corresponding to an image of a partial area of the left-eye original image and produce the first right-eye display image corresponding to an image of a partial area of the right-eye original image; and

the system further comprises a second image producer configured to produce, using at least one of the left-eye original image and the right-eye original image, a second display image corresponding to an image of an area including the partial area of the at least one of the left-eye and right-eye original images and being wider than that partial area.

2. An image display system according to claim 1, wherein:

the first left-eye display image and the right-eye display image respectively include both-eye image areas that are viewed overlapped with each other through the left eye and the right eye;

the first left-eye display image includes the both-eye image area and a left-eye image area that is viewed by the left eye; and

the first right-eye display image includes the both-eye image area and a right-eye image area that is viewed by the right eye.

3. An image display system according to claim 2, wherein the second display image includes the both-eye image area, the left-eye image area and the right-eye image area.

4. An image display system according to claim 1, wherein the image processing overlaps the left-eye captured images and the right-eye captured image with another image.

5. An image display system according to claim 1, further comprising:

a second image display unit configured to be viewable by a second viewer different from the first viewer; and

an image outputter configured to cause the second image display unit to display the second display image.

6. An image display system according to claim 5, further comprising a selector configured to select an image to be displayed by the second image display unit from the second display image, the first left-eye display image and the first right-eye display image.

7. An image display system according to claim 5, wherein the second image producer is configured to produce, as the image to be displayed by the second image display unit, a combined display image by combining the first left-eye and right-eye display images with each other.

8. An image display system according to claim 1, further comprising:

an image display apparatus including the left-eye and right-eye image capturers and the first image display unit; and

an image processing apparatus including the second image producer,

wherein the first image display unit is included in one of the image display apparatus and the image processing apparatus.

9. A non-transitory storage medium storing a computer program for causing a computer of an image display system to execute a display process, the image display system comprising:

a left-eye image capturer and a right-eye image capturer respectively configured to acquire, by image capturing, a left-eye captured image and a right-eye captured image; and

a first image display unit configured to allow a left eye and a right eye of a first viewer to view a first left-eye display image and a first right-eye display image, the display process comprising;

a process for (a) producing the first left-eye display image using a left-eye original image that is the left-eye captured image or a left-eye processed image produced by image processing performed on the left-eye captured image, and (b) producing the first right-eye display image using a right-eye original image that is the right-eye captured image or a right-eye processed image produced by image processing performed on the right-eye captured image, the first left-eye display image corresponding to an image of a partial area of the left-eye original image, the first right-eye display image corresponding to an image of a partial area of the right-eye original image; and

a process for producing, using at least one of the left-eye original image and the right-eye original image, a second display image corresponding to an image of an area including the partial area of the at least one of the left-eye and right-eye original images and being wider than that partial area.
