Abstract

Provided is an image output method of outputting predetermined image data from plural pieces of image data, the method including: acquiring a group including plural pieces of image data which are similar to each other; detecting a face turning angle with respect to a face image plane included in an image indicated by each image data belonging to the same group and a face rotation angle indicating a rotation angle in the face image plane; and outputting image data, in which the face turning angle and the face rotation angle are smaller than those of other image data, among the image data belonging to the same group.

Claims

1. An image output method, comprising:

acquiring a group including plural pieces of image data which are similar to each other;

detecting, for each piece of image data belonging to the group, a face turning angle with respect to a face image plane included in an image indicated by the piece of image data and a face rotation angle indicating a rotation angle of a face in the face image plane; and

outputting a piece of image data in which the face turning angle and the face rotation angle are smaller than those of other pieces of image data belonging to the group and in which the face is larger than that of the other pieces of image data belonging to the group.

2. An image output method, comprising:

acquiring a group including plural pieces of image data which are similar to each other;

detecting, for each piece of image data belonging to the group, a face turning angle with respect to a face image plane included in an image indicated by the piece of image data and a face rotation angle indicating a rotation angle of a face in the face image plane; and

outputting a piece of image data in which the face turning angle and the face rotation angle are smaller than those of other pieces of image data belonging to the group;

wherein the face turning angle and the face rotation angle are detected on the basis of a thumbnail image attached to each piece of image data.

3. An image output device, comprising:

a group acquiring unit acquiring a group including plural pieces of image data which are similar to each other;

a detecting unit detecting, for each piece of image data belonging to the group, a face turning angle with respect to a face image plane included in an image indicated by the piece of image data and a face rotation angle indicating a rotation angle of a face in the face image plane; and

a selecting unit outputting a piece of image data in which the face turning angle and the face rotation angle are smaller than those of other pieces of image data belonging to the group and in which the face is larger than that of the other pieces of image data belonging to the group.

4. A non-transitory computer-readable medium having a program stored thereon for causing a computer to execute a function for outputting image data, the function comprising:

a group acquiring function acquiring a group including plural pieces of image data which are similar to each other;

a detecting function detecting, for each piece of image data belonging to the group, a face turning angle with respect to a face image plane included in an image indicated by the piece of image data and a face rotation angle indicating a rotation angle of a face in the face image plane; and

a selecting function outputting a piece of image data in which the face turning angle and the face rotation angle are smaller than those of other pieces of image data belonging to the group and in which the face is larger than that of the other pieces of image data belonging to the group.
