An acquisition means for acquiring a moving image obtained by imaging a subject;
Face detecting means for detecting a face area of the subject from the frame of the moving image;
A motion for detecting motion information indicating motion of the face area from the past frame to the current frame from a correlation between the current frame of the moving image and a frame past the current frame. Detection means;
Storage means for accumulating motion information detected by the motion detection means for a frame prior to the current frame ;
And correction means based on the stored motion information in the storage means and detecting motion information for said current frame, performing a positional correction of the face area in the current frame by said motion detection means,
An image processing apparatus comprising:
Whether the subject whose face area was detected most recently by the face detecting means and the subject whose face area was last detected by the face detecting means before the face area of the subject was detected are different from each other Determination means for determining whether or not
When the determination unit determines that the subject whose face area was detected most recently and the subject whose face region was detected last are different from each other, the motion information stored in the storage unit is initialized. Updating means to
An image processing apparatus comprising: The motion detection means includes a frame in which the face area of the subject is not detected by the face detection means, or a frame in which the face area of the subject cannot be detected by the face detection means, and a frame earlier than the frame. The image processing apparatus according to claim 1, wherein motion information indicating a motion of the face area is detected from a correlation between frames.   The correcting means does not correct the position of the face area for a frame in which the face area of the subject can be detected by the face detecting means, and does not detect the face area of the subject by the face detecting means, or The image processing apparatus according to claim 2, wherein the face detection unit corrects the position of the face area in a frame in which the face area of the subject cannot be detected. Said determining means, the position of the detected face area to the nearest, the last when the difference divided et the face area and the position of the detected face area is determined to have moved predetermined amount or more The image processing apparatus according to claim 1, wherein the image processing apparatus determines that the subject is different. It said determining means, the position of the detected face area to the nearest, the difference divided et the face area and the position of the face region is corrected most recently moved predetermined amount or more by the correcting means The image processing apparatus according to claim 1, wherein the image processing apparatus determines that the subject is different when the determination is made. Said determining means, and the dynamic-out amount of the face region based on the motion information detected for the current frame by the motion detection means, the mean of the face area, based on the stored motion information in the storage means If the difference amount between the motion amount is preset threshold or more, the image processing apparatus according to any one of claims 1 to 5, wherein determining that the a different subject. The determination means calculates a similarity between the most recently detected face area image and the last detected face area image, and the calculated similarity is lower than a preset threshold value. The image processing apparatus according to claim 1, wherein the image processing apparatus determines that the subject is different. Imaging means for imaging a subject;
An image processing apparatus according to any one of claims 1 to 7,
Control means for controlling at least one of exposure adjustment and focus adjustment of the imaging means according to the face area of the subject detected by the image processing apparatus;
An imaging apparatus comprising: An acquisition means for acquiring a moving image obtained by imaging a subject;
Face detecting means for detecting a face area of the subject from the frame of the moving image;
A motion for detecting motion information indicating motion of the face area from the past frame to the current frame from a correlation between the current frame of the moving image and a frame past the current frame. Detection means;
Storage means for accumulating motion information detected by the motion detection means for a frame prior to the current frame ;
And correction means based on the stored motion information in the storage means and detecting motion information for said current frame, performing a positional correction of the face area in the current frame by said motion detection means,
An image processing apparatus control method comprising:
The determination means of the image processing apparatus includes a subject whose face area has been detected most recently by the face detection means, and a subject whose face area has been detected last by the face detection means before the face area of the subject is detected. A determination step of determining whether or not the subject is different from each other;
When the update unit of the image processing apparatus, the determination process and Oite the recently subject face area is detected and the last face area is detected object is determined to be a different object from each other, An update step of initializing the motion information stored in the storage means;
A control method for an image processing apparatus. Program for causing a computer to function as each unit of the image processing apparatus according to any one of claims 1 to 7.
