ELECTRONIC DEVICE, METHOD, AND COMPUTER PROGRAM PRODUCT

1 . An electronic device comprising:

a hardware processor configured to:

output a user interface for designating disparity sharpness related to a difference in sharpness at a border between an object and a background of the object, the difference resulting from a difference in depth-direction distances of the object and the background;

set the sharpness at the border between the background and the object based on the disparity sharpness designated via the user interface; and

generate one multiscopic image from parallax images.

2 . The electronic device according to claim 1 , wherein

the user interface is configured to designate disparity stability related to intensity at which chronological variation of a depth-direction distance of the object is suppressed, and

the hardware processor is further configured to generate one multiscopic image using the parallax images by setting the depth-direction distance of the object based on the disparity stability designated via the user interface.

3 . The electronic device according to claim 1 , wherein

the user interface is configured to designate a size of a first area in which the depth-direction distances are handled as same, from a second area not common among the parallax images, and

the hardware processor is further configured to generate one multiscopic image using the parallax images by setting the first area, based on the size of the first area, the size being designated via the user interface.

4 . The electronic device according to claim 1 , wherein

the user interface is configured to designate which one of image positions in each of the parallax images is used as the picture position,

the hardware processor is further configured to perform picture position correction on each of the parallax images by setting the designated image position in each of the parallax images as the picture position, the image position being designated via the user interface, and

the user interface is configured to visually present the designated image position.

5 . The electronic device according to claim 4 , wherein the user interface is configured to set a recessing amount or a protruding amount of the image position other than the picture position.

6 . A method executed on an electronic device, the method comprising:

outputting a user interface for designating disparity sharpness related to a difference in sharpness at a border between an object and a background of the object, the difference resulting from a difference in depth-direction distances of the object and the background; and

setting the sharpness at the border between the background and the object based on the disparity sharpness designated via the user interface, and generating one multiscopic image from parallax images.

7 . The method according to claim 6 , further comprising generating one multiscopic image using the parallax images by setting a depth-direction distance of the object based on a disparity stability designated via the user interface, wherein

the user interface is configured to designate the disparity stability related to intensity at which chronological variation of the depth-direction distance of the object is suppressed.

8 . The method according to claim 6 , further comprising generating one multiscopic image using the parallax images by setting a first area in which the depth-direction distances are handled as same, based on a size of the first area, the size being designated via the user interface, wherein

the user interface is configured to designate the size, from a second area not common among the parallax images.

9 . The method according to claim 6 , further comprising performing picture position correction on the parallax images by setting the designated image position in each of the parallax images as a picture position, the image position being designated via the user interface, wherein

the user interface is configured to designate which one of image positions in each of the parallax images is used as the picture position, and

the user interface is configured to visually present the designated image position.

10 . The method according to claim 9 , wherein the user interface is configured to set a recessing amount or a protruding amount of the image position other than the picture position.

11 . A computer program product including programmed instructions, embodied in and stored on a non-transitory computer readable medium, wherein the instructions, when executed by a computer, cause the computer to perform:

outputting a user interface for designating disparity sharpness related to a difference in sharpness at a border between an object and a background of the object, the difference resulting from a difference in depth-direction distances of the object and the background; and

setting the sharpness at the border between the background and the object based on the disparity sharpness designated via the user interface, and generating one multiscopic image from parallax images.

12 . The computer program product according to claim 11 , wherein the instructions, when executed by the computer, further cause the computer to perform generating one multiscopic image using the parallax images by setting a depth-direction distance of the object based on a disparity stability designated via the user interface, wherein

the user interface is configured to designate the disparity stability related to intensity at which chronological variation of the depth-direction distance of the object is suppressed.
