Photographing apparatus, method and program
First Claim
1. A photographing apparatus comprising:
- a photographing means for obtaining image data by taking a photograph of a subject;
a display means for displaying various kinds of information including the image data;
a release means for performing photographing operation;
a storage means for storing various kinds of information including the image data;
a photographing control means for obtaining a moving image of the subject by continuously taking photographs with the photographing means and displaying the moving image on the display means;
a face judgment means for performing processing, in a predetermined time interval, for judging whether a human face is included in a frame included in the moving image until a positive result is obtained in the judgment;
a face detection means for detecting a facial position in a frame, which is judged to include a face, if the face judgment means judges that the face is included in the frame; and
a control means for controlling the photographing means, the face judgment means, the face detection means, and the storage means so that the detected facial position is stored in the storage means, judgment is made as to whether the face is included in the next frame after the predetermined time, and if the judgment is positive, the facial position is detected, the facial position, which is stored in the storage means, is replaced by the newly detected facial position and the newly detected facial position is stored in the storage means, and until the release means performs the photographing operation, judgment is made as to whether the face is included in the next frame further after the predetermined time, and if it is judged that the face is included in the frame, the facial position is detected, and the newly detected facial position is stored in the storage means, and a frame obtained when the release means performs the photographing operation and/or a plurality of temporally precedent and/or subsequent frames of the obtained frame are stored in the storage means as the image data.

Abstract
Processing for judging whether a face is included in a frame is performed, in a predetermined interval, on each of frames included in a moving image of a subject, displayed on a monitor, until the judgment becomes positive. If it is judged that a face is included in a frame, the facial position is detected in the frame, and stored. Then, judgment is made as to whether a face is included in the next frame after predetermined time. If the judgment is positive, the facial position is detected. The previously stored facial position is replaced by the newly detected facial position, and the newly detected facial position is stored. These processes are repeated until photographing operation is performed by operating a release unit.

10. A photographing method at a photographing apparatus including a photographing means for obtaining image data by taking a photograph of a subject, a display means for displaying various kinds of information including the image data, a release means for performing photographing operation, a storage means for storing various kinds of information including the image data, and a photographing control means for obtaining a moving image of the subject by continuously taking photographs with the photographing means and displaying the moving image on the display means, the method comprising the steps of:
-
performing processing, in a predetermined time interval, for judging whether a human face is included in a frame included in the moving image until a positive result is obtained in the judgment;
detecting a facial position in a frame, which is judged to include a face, if it is judged that the face is included in the frame; and
storing the detected facial position in the storage means, judging whether the face is included in the next frame after the predetermined time, and if the judgment is positive, detecting the facial position, replacing the facial position, which is stored in the storage means, by the newly detected facial position and storing the newly detected facial position in the storage means, and until the release means performs the photographing operation, judging whether the face is included in the next frame further after the predetermined time, and if it is judged that the face is included in the frame, detecting the facial position, and storing the newly detected facial position in the storage means, and storing a frame, which is obtained when the release means performs the photographing operation and a plurality of temporally precedent and/or subsequent frames of the obtained frame in the storage means as the image data.

11. A program for causing a computer to execute an image processing method at a photographing apparatus including a photographing means for obtaining image data by taking a photograph of a subject, a display means for displaying various kinds of information including the image data, a release means for performing photographing operation, a storage means for storing various kinds of information including the image data, and a photographing control means for obtaining a moving image of the subject by continuously taking photographs with the photographing means and displaying the moving image on the display means, the program comprising the procedures for:
-
performing processing, in a predetermined time interval, for judging whether a human face is included in a frame included in the moving image until a positive result is obtained in the judgment;
detecting a facial position in a frame, which is judged to include a face, if it is judged that the face is included in the frame; and
storing the detected facial position in the storage means, judging whether the face is included in the next frame after the predetermined time, and if the judgment is positive, detecting the facial position, replacing the facial position, which is stored in the storage means, by the newly detected facial position and storing the newly detected facial position in the storage means, and until the release means performs the photographing operation, judging whether the face is included in the next frame further after the predetermined time, and if it is judged that the face is included in the frame, detecting the facial position, and storing the newly detected facial position in the storage means, and storing a frame, which is obtained when the release means performs the photographing operation and/or a plurality of temporally precedent and/or subsequent frames of the obtained frame in the storage means as the image data.
