(First embodiment)
FIG. 1 is a block diagram showing a configuration of a digital still camera 1 according to the first embodiment of the present invention. The digital still camera 1 according to the first embodiment includes a lens 11, an image sensor 12 that captures an image of a subject, a shutter 13 for capturing a still image, and an image signal obtained by the image sensor 12. An A / D conversion unit 14 that performs D conversion and a memory 15 that stores captured image data are provided.

  The digital still camera 1 also receives a mode switching unit 16 for switching between a moving image shooting mode and a still image shooting mode, a mode setting unit 17 for instructing the mode to the mode switching unit 16 and the shutter 13, and an operation from the user. And an operation unit 18. The mode switching unit 16 inputs the digital data input from the A / D conversion unit 14 to the image processing unit 20 in the moving image shooting mode. The mode switching unit 16 stores the digital data input from the A / D conversion unit 14 in the memory 15 in the still image shooting mode.

  In addition, the digital still camera 1 includes an image processing unit 20 having a function of detecting a predetermined movement of the subject based on a moving image shot in the operation shooting mode. In the present embodiment, the image processing unit 20 detects the wink of the subject and transmits a wink detection signal to the mode setting unit 17.

  In the image processing unit 20, a face detection unit 21 that detects a face image of the subject from the input image, an eye detection unit 22 that detects an eye image, and an eye tracking that images the eyes detected by the eye detection unit 22. Part 23. The eye tracking unit 23 tracks an eye image with respect to an image input at a predetermined time interval in the moving image shooting mode. The image processing unit 20 includes a wink detection unit 24. The wink detection unit 24 detects opening / closing of the eyes based on the eye image tracked by the eye tracking unit 23. The wink detection unit 24 detects wink when one eye is closed from the state where both eyes are opened and the both eyes are opened again.

  The mode setting unit 17 has a function of transmitting to the shutter 13 a signal instructing to turn off the shutter 13 in accordance with the wink detection signal transmitted from the image processing unit 20. When the shutter 13 is released, the digital still camera 1 captures a still image in the still image capturing mode. In the still image shooting mode, image data shot by the image sensor 12 is converted into digital data by the A / D conversion unit 14, and the converted digital data is recorded in the memory 15 via the mode switching unit 16. Further, the mode setting unit 17 transmits information on the set mode to the mode switching unit 16. Thereby, the mode switching unit 16 switches whether the digital signal output from the A / D conversion unit 14 is stored in the memory 15 or input to the image processing unit 18 based on the mode.

  FIG. 2 is a diagram illustrating an operation of taking a still image by the digital still camera 1. When the remote shooting mode is selected by the operation unit 18 in FIG. 1, the digital still camera 1 captures a subject in the moving image shooting mode, and inputs image data for each frame obtained by the shooting to the image processing unit 20. That is, the digital still camera 1 converts an image signal obtained by the image sensor 12 into a digital signal by the A / D conversion unit 14 and inputs the converted digital signal to the image processing unit 20 via the mode switching unit 16. (S10).

  Next, the face detection unit 21 of the image processing unit 20 performs face detection processing on each input frame image data, and determines whether or not a face image is detected (S11). Regarding face detection processing, for example, Viola, P. et al. Jones, M .; Computer Vision and Pattern Recognition, 2001. CVPR 2001. Proceedings of the 2001 IEEE Computer Society Conference on, Volume: 1, 8-14 Dec. 2001 Pages: I-511-518 vol. The method shown in 1 can be used.

  If no face image is detected by the face detection unit 21 (NO in S11), the image processing unit 20 waits for input of an image of the next frame (S10). If a face image is detected by the face detection unit 12 (YES in S11), processing by the eye detection unit 22 is performed.

  The eye detection unit 22 performs a process of detecting an eye image on the area where the face is detected (S12). For example, the eye detection unit 22 detects an eye image by using a template image of an eye and performing template matching on a search region. The eye detection unit 22 sets an image having the highest similarity as an eye image by template matching. When an eye image is detected, the eye detection unit 22 passes the eye detection position and the detection image to the eye tracking unit 23.

  The eye tracking unit 23 tracks the eye image of the person to be photographed based on the eye images sequentially input from the eye detection unit 22 and determines whether or not the eye tracking has been performed (S13). If the eye detection position in the current frame is within a predetermined range including the eye detection position in the previous frame, the eye tracking unit 23 determines that the eye tracking is successful, If the eye position in the frame is outside the predetermined range, it is determined that eye tracking has failed. If the eye tracking unit 23 fails in eye tracking, the eye tracking unit 23 restarts eye tracking from the current frame.

  The wink detection unit 24 of the image processing unit 20 determines whether or not it has been winked based on the eye detection position and the detected image (S14). The wink detection unit 24 detects a state where both eyes are open, then detects a state where one eye is closed, and detects a wink when detecting a state where both eyes are open again. To determine whether the eyes are open or closed, the eye detection unit 22 prepares a template with open eyes and a template with closed eyes, and detects a state transition. The reason why one eye is closed is to prevent erroneous detection of wink when both eyes are closed by blinking.

  When detecting the wink, the wink detection unit 24 notifies the mode setting unit 17 of wink detection information. The mode setting unit 17 uses the wink detection information as a trigger to cut the shutter 13 and shoot a still image (S15). The timing at which the mode setting unit 17 releases the shutter 13 may be the same as the timing at which the wink detection information is notified, or may be after a certain period of time has elapsed after receiving the notification of the wink detection information. The time from when wink is detected to when the shutter 13 is released can be set by the operation unit 18.

When the shutter 13 is released, the image sensor 12 of the digital still camera 1 captures a still image, and stores the captured still image data in the memory 16 (S16).
The configuration and operation of the digital still camera 1 according to the present embodiment have been described above.

  The digital still camera 1 according to the present embodiment detects an image of the subject's eye from a moving image captured in the moving image mode, and releases the shutter 13 when a wink is detected. Thereby, a still image can be taken at a timing desired by the subject.

  In this embodiment, the case where only one face is shown in the photographed image has been described. However, when a plurality of faces are shown, the eyes of a plurality of people are tracked and any one person winks. It is good also as a structure which cuts the shutter 13 when it detects.

(Second Embodiment)
Next, a digital still camera according to a second embodiment of the present invention will be described. The basic configuration of the digital still camera of the second embodiment is the same as that of the digital still camera 1 of the first embodiment (see FIG. 1), but the configuration of the image processing unit 20 is different.

  FIG. 3 is a diagram illustrating a configuration of the image processing unit 20 according to the second embodiment. The image processing unit 20 includes a feature amount generation unit 25 that generates a feature amount of an input image, a registered feature amount storage unit 26 that stores a feature amount of a face image of a predetermined person in advance, and a face image to be collated A collation feature amount storage unit 27 that stores feature amounts, a face collation unit 28 that performs face collation by comparing collation feature amounts and registered feature amounts, and a detection result by the wink detection unit 24 and collation by the face collation unit 28 A determination unit 35 that determines whether or not to release the shutter 13 based on the result is provided.

  Next, the operation of the digital still camera of the second embodiment will be described. In the digital still camera according to the second embodiment, a face image of a person who releases the shutter 13 is registered in advance, and when a still image is shot, the still image is shot using the registered person's wink.

  FIG. 4 is a diagram illustrating a registration operation of a face image of a person who releases the shutter 13. First, the digital still camera captures the subject in the moving image capturing mode, and inputs the captured image data to the image processing unit 20 (S20). The image processing unit 20 detects a face image and determines whether or not it has been detected (S21). If the face image cannot be detected (NO in S21), the image processing unit 20 waits for the input of the next frame image. When the face image can be detected (YES in S21), the eye detection unit 22 detects the eye image (S22). The eye detection unit 22 displays the detected eye position with a cross mark.

  The digital still camera accepts whether or not the detected face image may be a registered image by operating the button of the operation unit 18 (S23). When receiving an operation indicating that the image is acceptable as a registered image, the digital still camera generates a feature amount of the detected face image, and stores the generated feature amount in the registered feature amount storage unit 26 (S24).

  FIG. 5 is a diagram illustrating an operation of taking a still image by the digital still camera. When the remote shooting mode is selected, the digital still camera captures the subject in the moving image mode, inputs an image of each captured frame to the image processing unit 20 (S30), and detects a face image from the input image (S30). S31) A process of detecting an eye image is performed on the area where the face is detected (S32). Subsequently, the digital still camera performs eye tracking (S33) and detects wink (S34). The above operation is the same as steps S10 to S14 (see FIG. 2) in the operation of the digital camera 1 of the first embodiment.

  When the wink is detected by the wink detection unit 24 (YES in S34), the image processing unit 20 generates a feature quantity for matching from the detected face image, and the generated feature quantity and the registered feature The feature quantity stored in the quantity storage unit 26 is compared to check whether or not the detected face image matches the registered person's face image (S35). As a face matching method, for example, Turk, M., et al. A. Pentland, A .; P. Computer Vision and Pattern Recognition, 1991. Proceedings CVPR '91. , IEEE Computer Society Conference on, 3-6 June 1991 Pages: 586-591.

When the face images are collated (YES in S35), the digital still camera 1 releases the shutter 13 (S36). When the shutter 13 is released, the image sensor 12 of the digital still camera 1 captures a still image and stores the captured still image data in the memory 16 (S37).
The digital still camera according to the second embodiment of the present invention has been described above.

  When the wink is detected, the digital still camera of the second embodiment collates whether or not the face image of the person who winks matches the face image registered in advance. Since the shutter 13 is cut, the shutter 13 is cut when the registered person winks, and the shutter 13 is not cut even when another person winks. In the present embodiment, it is possible to designate a person who can release the shutter 13.

(Third embodiment)
FIG. 6 is a diagram illustrating a configuration of the digital still camera 3 according to the third embodiment, and FIG. 7 is a diagram of the digital still camera 3 as viewed from the front surface (photographer side). As shown in FIG. 7, the digital still camera 3 has LEDs 31 at the four corners of the front surface. The digital still camera 3 according to the third embodiment notifies the subject of the position of the face by blinking the LED 31.

  As shown in FIG. 6, the basic configuration of the digital still camera 3 of the third embodiment is the same as that of the digital still camera 1 of the first embodiment. In the digital still camera 3 according to the third embodiment, the image processing unit 20 includes a face position calculation unit 30 that calculates where in the captured image a face is based on an input image. The digital camera 3 controls the blinking of the LED 31 based on the face position calculated by the face position calculation unit 30.

  FIG. 8 is a diagram illustrating the operation of the digital still camera 3 according to the third embodiment. Note that the operation of the digital still camera 3 to release the shutter 13 by detecting the subject's wink is the same as in the first embodiment. FIG. 8 shows an operation for informing the subject of the position of the face.

  The digital still camera 3 takes an image with the image sensor 12 and inputs image data obtained by the imaging to the image processing unit 20 (S40). The image processing unit 20 performs face image detection processing from the captured image, and determines whether or not a face image is detected (S41). When a face image is detected (YES in S41), the face position calculation unit 30 of the image processing unit 20 calculates in which area of the input image the face image is detected (S42).

  The face position calculation unit 30 performs blinking control of the LED 31 based on the calculated face position. Specifically, the face position calculation unit 30 calculates to which direction the subject is moved and the face is in the center of the screen, and indicates the direction in which the subject should move by blinking the LED 31. To inform.

For example, as shown in FIG. 9, when a face is shown on the monitor 32 on the back surface of the digital still camera 3, if the subject moves in the direction of the arrow, the face comes to the center of the screen. Therefore, as shown in FIG. 10, the left LED 31 blinks (in FIG. 10, it is blacked out to indicate blinking) to inform the subject to move to the left side.
The digital still camera 3 according to the third embodiment of the present invention has been described above.

  The digital still camera 3 according to the third embodiment informs the person to be photographed of the direction to move to bring the face to the center by the LED 31 provided on the front surface. Thereby, a to-be-photographed person can be imaged in the center of a screen.

  In this embodiment, as the means for notifying the subject of the face position, the blinking of the LED 31 has been described as an example, but means for notifying the subject of the face position is not limited to the LED. For example, guidance may be performed using voice or the like.

  In the present embodiment, the example in which the LED 31 is provided to the digital still camera 1 of the first embodiment has been described. However, the configuration for informing the face position is the digital still camera of the second embodiment. It can also be applied to.

  In the present embodiment, the case where there is one subject is described. However, when there are a plurality of subjects, for example, a plurality of faces are detected, and the positions of the detected faces are detected. Similar processing can be performed using the center of gravity. Further, when applied to the digital still camera of the second embodiment, the processing can be performed so that the face position of the person registered in the registered feature amount storage unit 26 is in the center.

(Fourth embodiment)
Next, a digital still camera according to a fourth embodiment of the present invention will be described. The digital still camera according to the fourth embodiment is a digital still camera that releases a shutter according to the movement of the mouth of the subject. The basic configuration of the digital still camera of the fourth embodiment is the same as that of the digital still camera 1 of the first embodiment (see FIG. 1), but the configuration of the image processing unit 20 is different.

  FIG. 11 is a diagram illustrating a configuration of the image processing unit 20 according to the fourth embodiment. The image processing unit 20 according to the fourth embodiment includes a face image detection unit 21, a mouth detection unit 33, a mouth tracking unit 34, and a mouth operation detection unit 35. The mouth detection unit 33 detects a mouth image from the face image. The mouth tracking unit 34 has a function of tracking the mouth image detected by the mouth detecting unit 33. The mouth motion detection unit 35 has a function of detecting mouth motion based on the mouth information tracked by the mouth tracking unit 34.

  FIG. 12 is a diagram illustrating a still image shooting operation by the digital still camera according to the fourth embodiment. When the remote shooting mode is selected by the operation unit 18, the digital still camera captures the subject in the moving image mode and inputs the captured image for each frame to the image processing unit 20. That is, the digital still camera converts an image signal obtained by the image sensor 12 into a digital signal by the A / D conversion unit 14 and inputs the converted digital signal to the image processing unit 20 via the mode switching unit 16. (S50).

  Next, the face detection unit 21 of the image processing unit 20 performs face detection processing on each input frame image data, and determines whether a face image is detected (S51). If no face image is detected by the face detection unit 21 (NO in S51), the image processing unit 20 waits for input of an image of the next frame (S50). If a face image is detected by the face detection unit 12 (YES in S51), processing by the mouth detection unit 33 is performed.

  The mouth detection unit 33 performs a process of detecting an image of the mouth on the area where the face is detected (S52). For example, the mouth detection unit 33 creates a template image and detects the mouth image by a method of performing template matching on the search region. For the detected mouth image, for example, template matching is performed, and the image having the highest similarity is used as the mouth image. When the mouth image is detected, the mouth detection position and the detected image are passed to the mouth tracking unit 34.

  The mouth tracking unit 34 compares the mouth image of the previous frame, tracks the mouth image, and determines whether or not the mouth image has been tracked (S53). If the mouth detection position in the current frame is within a predetermined range including the mouth detection position in the previous frame, the mouth tracking unit 34 determines that the mouth has been successfully tracked, and If the position of the mouth in the frame is outside the predetermined range, it is determined that the mouth tracking has failed. If the mouth tracking unit 34 fails to track the mouth, the mouth tracking unit 34 restarts the mouth tracking from the current frame.

  The mouth movement detection unit 35 of the image processing unit 20 determines whether or not the mouth has moved based on the mouth detection position and the detected image. The mouth motion detection unit 35 detects a state where the mouth is open or closed, and then determines that there is a mouth motion when the mouth is closed or when the state where the mouth is opened is detected. To determine whether the mouth is open or closed, the mouth detection unit 33 prepares a template with an open mouth and a template with a mouth closed, and detects a state transition.

  When detecting the opening / closing operation of the mouth, the mouth operation detecting unit 35 notifies the mode setting unit 17 of the detection information of the opening / closing operation of the mouth. The mode setting unit 17 uses the detection information of the opening / closing operation of the mouth as a trigger to cut the shutter 13 and shoot a still image (S55). The timing at which the mode setting unit 17 releases the shutter 13 may be the same as the timing when the detection information of the opening / closing operation of the mouth is notified, or after a certain time has elapsed after receiving the detection information of the opening / closing operation of the mouth. It may be from. The time from when the opening / closing operation of the mouth is detected to when the shutter 13 is released can be set by the operation unit 18.

  The image sensor 12 of the digital still camera captures a still image when the shutter 13 is released, and stores the captured still image data in the memory 16 (S56). The configuration and operation of the digital still camera according to the fourth embodiment have been described above.

  The digital still camera according to the fourth embodiment detects a mouth image from a moving image shot in the moving image mode, and releases the shutter 13 when an opening / closing operation of the mouth is detected. Thereby, a still image can be taken at a timing desired by the subject.

  In this embodiment, the case where only one face is shown in the photographed image has been described. However, when multiple faces are shown, the mouths of multiple people are tracked, and any one person can hold the mouth. It is good also as a structure which cuts the shutter 13 when opening and closing.

  In the above-described embodiment, attention is paid only to opening / closing of the mouth as the mouth movement. However, movement of the mouth when a word is spoken may be detected.

  The digital still camera according to the embodiment of the present invention has been described in detail with reference to the embodiment, but the present invention is not limited to the above-described embodiment.

  In addition, the digital still camera of the present invention can be applied to taking a registered image or a collation image in a face recognition system. When photographing for authentication, it is desirable that the orientation, facial expression, etc. of the subject to be photographed are the same as at the time of registration. However, when automatically taking a registered image or a collation image, the face orientation and facial expression often change. By using the present invention, the person to be photographed can determine the timing of photographing, so that the orientation and expression of the face at the time of photographing can be made constant, and the authentication accuracy can be improved.

  As described above, the present invention is useful as a digital still camera or the like having a moving image shooting mode and a still image shooting mode that can release a shutter at a timing desired by a subject by remote control.
