Abstract

According to one embodiment, an image processing device includes a readiness determining unit configured to determine whether or not a state of a face image included in an image at one time out of images obtained at a plurality of different times is a ready state that satisfies a condition for performing three-dimensionality determination, three-dimensionality determination is determining whether the object is three-dimensional or not; an initiation determining unit configured to determine whether or not a state of a face image included in an image at different time from the image at the one time is an initiation state changed from the ready state; and a first three-dimensionality determining unit configured to perform the three-dimensionality determination on the face images included in the images when it is determined that the state is the initiation state.

Claims

1. An image processing device comprising:

a readiness determining unit configured to determine whether or not a state of a face image included in an image at one time out of images obtained at a plurality of different times is a ready state that satisfies a condition for performing three-dimensionality determination, three-dimensionality determination is determining whether the object is three-dimensional or not;

an initiation determining unit configured to determine whether or not a state of a face image included in an image at different time from the image at the one time is an initiation state changed from the ready state; and

a first three-dimensionality determining unit configured to perform the three-dimensionality determination on the face images included in the images when it is determined that the state is the initiation state.

2. The device according to claim 1, wherein the ready state is a state in which the face images are stationary in the images.

3. The device according to claim 2, wherein the initiation determining unit determines that the state is the initiation state when there is a motion in the face image from the face image in the ready state.

4. The device according to claim 3, wherein in the ready state, a face size, a face orientation and a face motion amount in the face image are within set ranges.

5. The device according to claim 4, comprising:

at least one second three-dimensionality determining unit different from the first three-dimensionality determining unit; and

an integrated determining unit configured to determine that the face image is three-dimensional when one of the first three-dimensionality determining unit and the second three-dimensionality determining unit determines that the face image is three-dimensional.

6. An image processing method comprising:

determining, whether or not a state of a face image included in an image at one time out of images obtained at a plurality of different times is a ready state that satisfies a condition for performing three-dimensionality determination;

determining, whether or not a state of a face image included in an image at different time from the image at the one time is an initiation state changed from the ready state; and

performing, the three-dimensionality determination on the face images included in the images when it is determined that the state is the initiation state.

7. A computer program product comprising a computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform:

determining whether or not a state of a face image included in an image at one time out of images obtained at a plurality of different times is a ready state that satisfies a condition for performing three-dimensionality determination;

determining whether or not a state of a face image included in an image at different time from the image at the one time is an initiation state changed from the ready state; and

performing the three-dimensionality determination on the face images included in the images when it is determined that the state is the initiation state.
