  However, a camera having such a facial expression automatic shooting function can display the number of shots or the number of remaining shots with respect to the capacity of the storage medium, but displays the number of shots of a predetermined facial expression such as a smile. I can't.

(1) A digital camera according to a first aspect of the present invention includes an imaging unit that images a subject to generate a subject image, a facial expression data storage unit that stores a predetermined facial expression as facial expression data, Detection means for comparing the facial expression of a person with facial expression data to detect that the facial expression of the person corresponds to a predetermined facial expression, and recording means for recording a subject image including the predetermined facial expression detected by the detection means And a counting means for counting the number of photographed subject images including a predetermined facial expression recorded by the recording means, and a display means for displaying the number of photographed images counted by the counting means.

  According to the digital camera of the present invention, it is possible to display how many subject images including a predetermined facial expression are taken.

Hereinafter, a digital camera according to an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing a configuration of a digital camera according to an embodiment of the present invention.

  As shown in FIG. 1, the digital camera includes a photographing lens 11, an aperture 12, an image sensor 13, a buffer memory 14, an image processing unit 15, an image recording unit 16 such as a memory card, and a control unit 20. The digital camera includes a face detection unit 21, a face data storage unit 22, a facial expression detection unit 23, a facial expression data storage unit 24, a facial expression setting unit 25, a facial expression level data storage unit 26, and a facial expression level setting unit 27. And a liquid crystal display 28. The digital camera further includes a counting unit 30, an automatic photographing unit 31, a face registration data storage unit 32, a face recognition unit 33, a facial expression photographing mode setting unit 40, a search unit 41, and a game mode setting unit.

  The photographing lens 11 includes a plurality of lenses including a zoom lens and a focus lens, and forms a subject image on the image sensor 13. In FIG. 1, for the sake of simplicity, the taking lens 11 is shown as a single lens. The imaging element 13 generates an image signal by photoelectrically converting the subject light L1 from the photographing lens 11.

  The image signal output from the image pickup device 13 is sent to the image processing unit 15 via the buffer memory 14, where predetermined various image processing is performed. At the stage before the start of shooting, the image signal from the image sensor 13 is sent to the liquid crystal display 28 via the buffer memory 14, the image processing unit 15, and the control unit 20, and displayed as a through image. At the photographing stage, the image signal from the image sensor 13 is recorded in the image recording unit 16 via the buffer memory 14 and the image processing unit 15. The image recording unit 16 adds and records additional information such as text or symbols to the image information.

  The face detection unit 21 inputs through image data sent from the image sensor 13 via the buffer memory 14, the image processing unit 15, and the control unit 20, and the through image data is stored in the face data storage unit 22 in advance. The face of the subject person in the through image is detected by comparing with the existing face data. The detected face area image is sent from the face detection unit 21 to the control unit 20. The face data storage unit 22 stores, for example, feature point data relating to the shape of eyebrows, eyes, nose, and lips.

  For the face detection, for example, a detection method disclosed in Japanese Patent Laid-Open No. 2001-16573 can be used. In this detection method, feature points are extracted from an input image to detect the face area, face size, etc. of the subject. The feature points include end points of eyebrows, eyes, nose, lips, and face contour points, such as the head vertex and the lower end point of the chin.

  As other face detection, for example, a detection method disclosed in JP-A-2005-157679 can be used. In this detection method, first, a luminance difference between two pixels in an input image is learned as a feature amount, and an estimated value indicating whether or not a face exists in a predetermined region in the input image based on the feature amount. And when the estimated value is 1 or more, it is determined that a face exists in the predetermined area.

  The facial expression detection unit 23 inputs an image of the face area detected by the face detection unit 21 via the control unit 20, and the facial expression of the image of the facial area is stored in advance in the facial expression data storage unit 24. By comparing with the predetermined facial expression data, it is detected that the facial expression of the subject person in the face area image corresponds to the predetermined facial expression data. There are various types of facial expressions such as a smile, a crying face, an angry face, a surprised face, a sleeping face, and the facial expression data storage unit 24 can store these data. Smile data and crying face data are stored. The facial expression setting unit 25 is an operation unit that sets the type of facial expression of the subject person from the outside. In this embodiment, the facial expression setting unit 25 can set a smile and a crying face as facial expressions.

  When the facial expression detection unit 23 detects a facial expression of an image in the face area, a detection method disclosed in Japanese Patent Application Laid-Open No. 2008-42319 can be used. In this detection method, for example, in order to detect a smile, the type of facial expression is determined based on whether the face of the detected image is close to the two facial expressions of a smile and a normal face. .

  Further, the facial expression detection unit 23 can detect not only the facial expression but also the degree of facial expression (expression level). That is, the facial expression detection unit 23 inputs the facial region image detected by the facial detection unit 21 from the control unit 20, and the facial expression level data storage unit 27 stores the degree of facial expression of the facial region image in advance. By comparing with the predetermined facial expression level data, it can be detected that the facial expression level of the face of the subject person in the face area image corresponds to the predetermined facial expression level data.

The facial expression level data storage unit 26 stores, for example, smile level data (for example, smile level data) indicating the characteristics of each smile when the smile level (smile level value) is 20% smile, 50% mid-smile, and 100% smile. , The interval between feature points) is stored for each smile level.
The facial expression level setting unit 27 is an operation unit for setting smile level values of 20%, 50%, and 100% from the outside.

  As a method for determining the degree of smile, for example, a method disclosed in Japanese Patent Application Laid-Open No. 2004-46591 can be used. This determination method evaluates the degree of smile for the smile of the input partial image, and calculates a smile evaluation value. When evaluating smiles, calculate the evaluation points for the shape of each element of the eyebrows, pupils, and lips by referring to the smile data stored in advance. Value.

  When the facial expression detection unit 23 detects that the facial expression of the subject is a predetermined facial expression or corresponds to a predetermined expression level, it outputs a detection signal to the control unit 20. When receiving the detection signal, the control unit 20 outputs a signal to the automatic photographing unit 31 and the counting unit 30. The automatic photographing unit 31 outputs an operation signal to the photographing lens 11, the diaphragm 12, and the image sensor 13 in accordance with a signal emitted from the control unit 20 to photograph the subject. The photographed subject image is recorded in the image recording unit 16.

  The counting unit 30 counts the total number of shots, the number of shots of smiles and crying faces that can be set by the facial expression setting unit 25, and smile level values 20% and 50 that can be set by the facial expression level setting unit 27. % And 100% are counted separately. For this purpose, the counting unit 30 includes a counter for the total number of shots, a counter for the number of smiling shots, a counter for the number of shots of crying faces, a counter for the number of shots with a smile level of 20%, and the number of shots with a smile level of 50%. Counter and a counter for the number of shots with a smile level of 100%.

  The facial expression detection unit 23 detects a smile when a detection signal A is detected, a detection signal B when a crying face is detected, and a detection signal C and a detection signal D when a smile with a smile level value of 20%, 50%, and 100% is detected. The detection signal E is sent to the control unit 20. When receiving the detection signal A, the control unit 20 sends a counting signal to the smile shooting number counter, and when receiving the detection signal B, the control unit 20 sends a counting signal to the crying face shooting number counter. When the detection signal E is received, a count signal is sent to the counter for the number of shots with smile level values of 20%, 50% and 100%, respectively. The total number of shots is counted by a known method.

  The liquid crystal display 28 is provided on the back surface of the digital camera, and is used for displaying a through image or reproducing a subject image recorded in the image recording unit 16. The liquid crystal display 28 has a variable screen angle and direction, and the screen can be directed toward the subject. The liquid crystal display 28 can display not only images but also information such as the above-described expression level value and the number of photographed subject images.

  In the face registration data storage unit 32, a face image of a specific person is registered as data with an index such as the name of the person. The person registration is performed, for example, by photographing the guide displayed on the screen of the liquid crystal display 28 with the eyes and mouth of the person aligned. By registering a person, it is also possible to photograph the person with priority over unregistered persons.

  The face recognition unit 33 inputs the face area image detected by the face detection unit 21 via the control unit 20, and collates the face area image with the face registration data registered in the face registration data storage unit 32. By doing this, it is determined whether or not the face of the subject person in the image of the face area is the face of a registered specific person, and the determination result is sent to the control unit 20. For the face recognition, for example, a method disclosed in Japanese Patent Application Laid-Open No. 2004-62560 can be used.

  The facial expression shooting mode setting unit 40 is an operation for setting ON / OFF a mode in which automatic shooting is performed when the facial expression type or facial expression level of the subject person corresponds to a predetermined facial expression or a predetermined facial expression level. Part.

  The search unit 41 is an operation unit that searches and reproduces information such as a subject image recorded in the image recording unit 16. The digital camera according to the present embodiment is set to “shooting mode” which is a shooting preparation state when the power is turned on, but can be set to “playback mode” by operating the search unit 41. In the reproduction mode, in addition to searching and reproducing image information, the numerical value of the number of shots counted by the counting unit 30 is graphed and displayed on the screen of the liquid crystal display 28, or the counted number of shots is displayed on the liquid crystal display. The desired subject image can be selected by being displayed on the 28 screens. These will be described later.

  The game mode setting unit 42 turns on a mode for performing a game for competing for the number of shots using the number of shots counted for a predetermined facial expression and the number of shots counted for each predetermined facial expression level. This is an operation unit for setting / OFF.

When automatically photographing a smiling face of a subject person using the digital camera configured as described above, the operation is as follows.
First, the facial expression shooting mode setting unit 40 is turned on, and the facial expression setting unit 25 sets a smile as the type of facial expression. The facial expression detection unit 23 compares the face image of the subject person detected by the face detection unit 21 with the smile data stored in the facial expression data storage unit 24. Output to the control unit 20. The control unit 20 activates the automatic photographing unit 31 in response to the detection signal A and sends a counting signal to the counter for the number of smiling shots of the counting unit 30. Thereby, the automatic photographing unit 31 photographs the smile of the subject person. The counting unit 30 counts the number of smile shots by one using the counter for the number of smile shots, and the liquid crystal display 28 displays the number of shots. Thereafter, when a smile is detected again, the same operation is performed and the count number is two. As a result, the smiling image of the subject is shot and the number of shots is counted.

Next, a case where automatic shooting is performed when a specific person among a plurality of subject persons smiles will be described.
First, the face image of the specific person is registered and stored in the face registration data storage unit 32 by a known method. The face recognition unit 33 compares the face area image of the subject person detected by the face detection unit 21 with the face registration data registered in the face registration data storage unit 32 and determines that the subject person is a registered person. Then, the determination result is sent to the control unit 20. When the facial expression detection unit 23 detects the smile of the registered person, the facial expression detection unit 23 outputs a detection signal A to the control unit 20. As a result, the automatic photographing unit 31 outputs an operation signal to the photographing lens 11, the diaphragm 12, and the image sensor 13 to photograph a smile of a specific person. The counting unit 30 counts one as the number of smile shots.

  Note that the counting unit 30 counts the number of smiling faces photographed, the number of crying faces photographed, and the number of smile levels photographed for each registered person registered in the face registration data storage unit 32. When there are a plurality of registered persons, the counting unit 30 can also be configured to count the number of smile images taken for each registered person.

  The digital camera according to the present embodiment operates similarly when the facial expression level is set by the facial expression level setting unit 27. As a result, each image is photographed with a smile level value of 20%, 50%, and 100% of the subject, and the number of each photographed image is counted.

  Hereinafter, each function and each mode of the digital camera according to the present embodiment will be described in detail with reference to the screen of the liquid crystal display 28 shown in FIGS. In the following description, as the predetermined facial expression levels, three smile levels of 20% smile, 50% medium laughter, and 100% big laughter are set by the facial expression level setting unit 27.

In addition, the screen size may be automatically changed according to the smile level, for example, a large laughing image has a large screen size and a smile has a small screen size.

(5) Game Mode The digital camera according to the present embodiment has a game mode. When the game mode is set to ON by the game mode setting unit 42, a smile shooting mode for automatically shooting when a smiling face of a subject person is detected. When set to ON, for example, the game can be played according to the following rules.
(A) The number limit rule sets a limit on the number of shots and competes for the total number of smile points in the limit number. The smile point is a point display of a smile level. For example, a smile is 1 point, a medium smile is 2 points, and a big smile is 3 points.
(B) The time limit rule is to determine the shooting time and compete for the number of smile images shot within the time limit.
(C) The time trial rule determines the target number of smile images and competes for the time (required time) until the target number is reached.

To start the game, first, the game mode setting unit 42 selects any one of the above (a), (b), and (c).
Now, when a game according to the number limit rule (a) is selected, the input of the limit number is required on the screen of the liquid crystal display 28. Here, five sheets are set as the limit number. Pressing the OK button on the screen or pressing the release button starts the game. When a smile is detected, the number of shots of the smile image is counted, and the number of points is always displayed as a bar graph 56 as shown in the screen of the liquid crystal display 28 shown in FIG. 56 is updated. When the number of shots reaches the limit, shooting is prohibited and a game end screen is displayed. The number of points for each photographer is aggregated. For example, photographers within the top 10 place the user name and store it in the memory.

  When a game according to the time restriction rule (b) is selected, the time limit and the smile level to be counted are requested on the screen of the liquid crystal display 28. Here, 60 seconds is set as the time limit and 100% laughter is set as the smile level to be counted. After the game starts, the number of shots of a laughing smile image is counted, and the number of shots is always displayed as a bar graph 57 as shown in the screen of the liquid crystal display 28 shown in FIG. 7, and every time the number of shots is counted. The bar graph 57 is updated. A clock 58 for measuring the time limit is also displayed on the screen. When the time limit is reached, shooting is prohibited and a game end screen is displayed. The number of shots for each photographer is tabulated. For example, photographers within the top 10 place the user name and store it in the memory. This time limit rule may compete for the total smile points as in the number limit rule. In this case, the smile level is not input.

  When a game based on the time trial rule (c) is selected, input of the target number and the smile level to be counted is requested on the screen of the liquid crystal display 28. Here, the target number of sheets is set to 5 and 100% laughter is set as the smile level to be counted. After the game starts, the same display as the screen of the liquid crystal display 28 shown in FIG. 7 is made. That is, the number of shots of a smiley image of a big laugh is counted, the number of shots is always displayed as a bar graph 57, and the bar graph 57 is updated each time the number of shots is counted. The elapsed time from the start of the game is also displayed on the screen by a clock 58. When the target number is reached, shooting is prohibited and a game end screen is displayed. The required time for each photographer is totaled, and for example, photographers within the top 10 place the user name and store it in the memory. Also in this time trial rule, the total of smile points may be competed as in the number limit rule. In this case, the smile level is not input.

The digital camera according to the present embodiment has the following operational effects.
(1) When the smile of the subject person is detected, the automatic photographing unit 31 photographs the smile of the subject person, the count unit 30 counts the number of photographed subject images, and the liquid crystal display 28 displays the number of photographed images. Therefore, it is possible to easily know how many smiling subject images have been taken.
(2) Similarly, when the smile level of the subject person is detected, it is possible to easily know how many subject images for each smile level have been taken.
(3) By registering a specific person among a plurality of subject persons, a smile of the registered person or a smile of a predetermined smile level is recognized, and a smile image of the registered person is preferentially shot and the number of shots is taken. I can know.

Variations of the digital camera according to the present embodiment are as follows.
(1) Counting the number of shots In the above embodiment, based on the detection signal from the facial expression detection unit 23, the automatic shooting unit 31 captures the smile of the subject person, and the counting unit 30 sets the number of counting signals. By counting, the number of photographed subject images is counted. As a modified example, the counting unit 30 may count using the additional information obtained by adding the number of captured subject images recorded in the image recording unit 16 to the image information. For example, the counting unit 30 may pick up a subject image with additional information “smile” and count the number of images. Counting the number of counting signals is performed almost simultaneously with automatic shooting. However, since automatic shooting is always performed when counting, the same result as counting the number of recorded subject images can be obtained.

(2) Normal Shooting Mode In the above description, the number of shots such as smiles is set to the smile automatic shooting mode by operating the facial expression shooting mode setting unit 40, and the facial expression detection unit 23 detects the smile of the subject person. Thus, the number of facial expressions when the automatic photographing was performed was obtained. However, the counter unit 30 is not limited to the number of shots in the smile automatic shooting mode as described above, but also in a normal shooting mode, that is, a mode in which the photographer performs a shooting start operation such as a shutter release at an arbitrary timing. The number of shots can be counted.

In order to count the number of shots such as smiles in this normal shooting mode, for example, the following method (a) or (b) may be executed.
In the method (a), even in the normal shooting mode, the facial expression detection unit 23 always detects a smile image of the subject person and detects whether or not the subject image when the photographer releases the shutter is a smile. If it is a smile, a detection signal is generated. As a result, the counter unit 30 counts the number of smile shots. Of course, at this time, the automatic photographing unit 31 is inoperative because the facial expression photographing mode is not set. Therefore, the automatic photographing unit 31 does not respond to this detection signal and does not perform an automatic photographing operation. In the normal shooting mode, when the shutter button is pressed in the playback mode, the mode is switched to the shooting mode. When the shutter button is fully pressed after switching to the shooting mode, the smile detection operation starts.

  In the method (b), in response to the detection signal from the facial expression detection unit 23, the smile image when the control unit 20 releases the shutter and the smile information as additional information are associated with each other, and the smile image and the smile information are recorded. Part 16 is recorded. The counting unit 30 counts the number of photographed smile images based on the smile information.

(3) Other functions (a) Message display When a digital camera reaches a predetermined number of, for example, 100, 200, or 1000 subject images such as smiles counted by the counting unit 30, a predetermined message is displayed. May be added to the screen of the liquid crystal display 28. The predetermined message is, for example, “100 smile images have been achieved. Congratulations!”.
(B) Storage on Website A function may be added to the digital camera to automatically upload subject images such as smiles counted by the counting unit 30 onto the web using a wireless function such as wifi. When automatically increasing, a confirmation display as to whether to increase may be displayed on the screen of the liquid crystal display 28.

The term “number of shots” used in this specification may be the number of shots taken since the start of use of the digital camera, or the number of shots related to the subject image recorded in the image recording unit 16. It may also be the number of shots for both of these. In the case of the number of shots for both, for example, for smiles, the counting unit 30 counts the cumulative number of shots and counts the number of shots of smiley images in the image recording unit 16.
