## Abstract

An information processing apparatus comprising a situation acquiring unit configured to acquire a situation of one movable object, and a storing execution unit configured to store a face image of an occupant on the one movable object, captured by an image-capturing unit mounted on the one movable object when the one movable object is in a predetermined situation, as a face image of the occupant with neutral facial expression is provided.

## Claims

### Claim 1

An information processing apparatus comprising:
at least one processor;
a situation acquiring unit configured to acquire a situation of one movable object using the at least one processor; and
a storing execution unit configured to store a face image of an occupant of the one movable object captured by an image-capturing unit mounted on the one movable object in response to when the one movable object is in a predetermined situation, as a face image of the occupant with neutral facial expression using the at least one processor.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1 comprising an emotion estimating unit configured to estimate emotion of the occupant of the one movable object, by comparing the face image of the occupant captured by the image-capturing unit and the face image of the occupant with neutral facial expression stored by the storing execution unit using the at least one processor.

### Claim 3 (depends on 2)

The information processing apparatus according to claim 2, wherein the one movable object is an automobile,
the situation acquiring unit acquires an operation situation of a steering wheel of the one movable object, and
the storing execution unit stores the face image of the occupant, captured by the image-capturing unit while the operation situation of the steering wheel of the one movable object is a predetermined situation, as the face image of the occupant with neutral facial expression.

### Claim 4 (depends on 3)

The information processing apparatus according to claim 3, wherein the storing execution unit stores the face image of the occupant captured by the image-capturing unit while a rotation angle of a steering wheel of the one movable object falls in a predetermined range from a reference position, as the face image of the occupant with neutral facial expression.

### Claim 5 (depends on 1)

The information processing apparatus according to claim 1, wherein the situation acquiring unit acquires a situation of a path through which the one movable object moves, and
the storing execution unit stores the face image of the occupant captured by the image-capturing unit in response to when the situation of the path through which the one movable object moves is a predetermined situation, as a face image of the occupant with neutral facial expression.

### Claim 6 (depends on 5)

The information processing apparatus according to claim 5, wherein the one movable object is an automobile and the situation acquiring unit acquires the situation of a road on which the one movable object travels.

### Claim 7 (depends on 6)

The information processing apparatus according to claim 6, wherein the storing execution unit stores, in response to when the road at a predetermined distance from a position of the one movable object in the moving direction of the one movable object is a straight road, the face image of the occupant captured by the image-capturing unit while the one movable object travels along the straight road, as the face image of the occupant with neutral facial expression.

### Claim 8 (depends on 7)

The information processing apparatus according to claim 7, wherein the storing execution unit stores the face image of the occupant captured by the image-capturing unit while the one movable object travels along the straight road, as the face image of the occupant with neutral facial expression, under a condition that another vehicle is not present on the straight road.

### Claim 9 (depends on 7)

The information processing apparatus according to claim 7, wherein the storing execution unit stores the face image of the occupant captured by the image-capturing unit while the one movable object travels along the straight road, as the face image of the occupant with neutral facial expression, under a condition that a traffic light does not exist on the straight road.

### Claim 10 (depends on 7)

The information processing apparatus according to claim 7, wherein the storing execution unit stores the face image of the occupant captured by the image-capturing unit while the one movable object travels along the straight road, as the face image of the occupant with neutral facial expression, under a condition that an intersection does not exist on the straight road.

### Claim 11 (depends on 6)

The information processing apparatus according to claim 6, wherein the storing execution unit stores, in response to when the road along which the one movable object travels from a position of the one movable object for a predetermined period is a straight road, the face image of the occupant captured by the image-capturing unit while the one movable object travels along the straight road, as the face image of the occupant with neutral facial expression.

### Claim 12

A non-transitory computer-readable storage medium having stored thereon a program for causing a computer to function as:
a situation acquiring unit configured to acquire a situation of a one movable object; and
a storing execution unit configured to store a face image of an occupant of the one movable object, captured by an image-capturing unit mounted on the one movable object in response to when the one movable object is in a predetermined situation, as a face image of the occupant with neutral facial expression.
