## Abstract

An information processing apparatus (1) includes a viewpoint position detection unit (15) and a correction processing unit (11). The viewpoint position detection unit (15) detects a viewpoint position (PS) of an observer. The correction processing unit (11) detects a gaze point (GP) on a viewpoint image (VPI) corresponding to the viewpoint position (PS). The correction processing unit (11) blurs an outer edge of the viewpoint image (VPI) away from the gaze point (GP) in a parallax direction.

## Claims

### Claim 1

An information processing apparatus comprising:
a viewpoint position detection unit that detects a viewpoint position of an observer; and
a correction processing unit that detects a gaze point on a viewpoint image corresponding to the viewpoint position and blurs an outer edge of the viewpoint image away from the gaze point in a parallax direction.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1,
wherein the viewpoint image includes a plurality of line images adjacent in a parallax direction, and
the correction processing unit selectively blurs one or more line images, in which the gaze point is not located, among the plurality of line images.

### Claim 3 (depends on 2)

The information processing apparatus according to claim 2,
wherein the correction processing unit blurs a line image more greatly as the line image is located farther from the gaze point.

### Claim 4 (depends on 1)

The information processing apparatus according to claim 1,
wherein the correction processing unit varies distribution of a blur amount in the viewpoint image in accordance with a moving speed of the viewpoint position.

### Claim 5 (depends on 4)

The information processing apparatus according to claim 4,
wherein the blur amount decreases as a moving speed of the viewpoint position increases.

### Claim 6

An information processing method executed by a computer, comprising:
detecting a viewpoint position of an observer;
detecting a gaze point on a viewpoint image corresponding to the viewpoint position; and
blurring an outer edge of the viewpoint image away from the gaze point in a parallax direction.

### Claim 7

A program causing a computer to execute:
detecting a viewpoint position of an observer;
detecting a gaze point on a viewpoint image corresponding to the viewpoint position; and
blurring an outer edge of the viewpoint image away from the gaze point in a parallax direction.
