<Function block configuration>
Next, main functional blocks in the imaging apparatus according to the present embodiment will be described with reference to FIG.
As shown in FIG. 3, the main functional blocks in the imaging apparatus according to the present embodiment are a face image detection unit 101, a detection list 102, a start condition storage unit 103, a start condition setting unit 104, and a display control unit. 48 and a display unit 106.

  The face image detection unit 101 is provided in the control circuit 41 of the imaging apparatus in FIG. 2, and the detection list 102 and the activation condition storage unit 103 are provided in the user data memory 43 of the imaging apparatus in FIG. The setting unit 102 is provided in the operation input unit 45 of the imaging apparatus in FIG.

  The face image detection unit 101 detects a human face image from the captured image captured by the electronic imaging unit 33 and extracts the face image. As a specific method for detecting a face portion in an image, a publicly known technique can be used, and a detailed description thereof is omitted. For example, feature information common to a human face is stored in advance. There is a method in which feature information extracted from each part of a photographed image is compared with feature information stored in advance, and an image portion having a predetermined degree of similarity or more is determined as a face. Here, as the feature information, information such as a color such as a skin color or a relative positional relationship of facial parts is generally used.

  In addition, when detecting face images continuously, the accuracy and efficiency of detection can be improved by following a moving face using information such as the position and size of the face image detected immediately before. There is also a method of performing a tracking operation to improve the above.

  The detection list 102 is a list in which the face image newly detected in the image data, its position information, the following face image, and its position information are recorded and updated. The activation condition storage unit 103 stores an operation mode data table, a data table related to automatic selection start conditions, a data table that defines conditions for determining the number of simultaneously selected persons, a data table that defines automatic selection conditions, and the like.

  As shown in FIG. 4, the operation mode data table describes an operation mode for executing the roulette mode. Specifically, in the “roulette mode at the time of moving image shooting”, a face image is automatically selected during moving image shooting, and an identification display of the automatically selected face image is executed along with this automatic selection process. In the “roulette mode during moving image reproduction”, a face image is automatically selected during moving image reproduction, and the identification display of the automatically selected face image is executed along with this automatic selection process. Furthermore, in the “roulette mode during still image reproduction”, a face image is automatically selected during still image reproduction, and the identification display of the automatically selected face image is executed along with this automatic selection process.

  As shown in FIG. 5, the data table relating to the start condition of the automatic selection operation is as follows: 1) The face image selected at the time of the previous automatic selection execution is no longer detected (followed); 2) Currently detected (followed) The number of all face images detected is 3 or more. 3) The number of all face images detected (followed) at the time of the previous automatic selection execution and the number of all face images currently detected (followed). 4) The number of face images that were detected (follow-up) at the time of the previous automatic selection execution, but are no longer detectable (follow-up) is 2 or more. 5) Detected at the time of the previous automatic selection execution. The number of face images that have not been (followed) but are newly detected (followed) is 2 or more, 6) random, 7) alive, undetected faces in the detected (followed) face images in the past 8) Elapsed time since the last automatic selection Sec or more, and conditions etc. are shown, the user is able to select these conditions appropriately, in combination with AND or OR or the like. Moreover, about said numerical part, a user can set arbitrarily.

  The data table relating to the conditions for determining the number of simultaneously selected persons determines the number of persons who perform facial image identification display (roulette mode). As shown in FIG. 6, 1) 1 person (fixed), 2) 2 persons Conditions such as (fixed), 3) 10% of the number of all face images detected (followed) at the time of automatic selection execution, and 4) random are shown.

  The data table related to the automatic selection condition indicates the condition on how to select the face images of the number of persons selected by the data table related to the determination condition of the simultaneously selected number of persons, as shown in FIG. Randomly selected from all face images currently detected (followed) 2) Randomly selected from previously unselected face images 3) Fastest among unselected face images in the past Detected face image, 4) Among the face images not selected in the past, the conditions such as the face image closest to the camera are shown.

  The activation condition setting unit 104 determines an operation mode data table stored in the activation condition storage unit 103, a data table related to automatic selection start conditions, a data table defining conditions for determining the number of simultaneously selected persons, and automatic selection conditions. Set the activation conditions that the user arbitrarily selects from the selected data table. The display control unit 48 refers to the detection list 102 based on the activation condition set in the activation condition setting unit 104 while reproducing a moving image or a still image, and performs control for identifying and displaying a specific face image. I do. Based on the control of the display control unit 48, the display unit 106 identifies and displays a specific face image while displaying a moving image or a still image.

<Processing during movie shooting>
With reference to FIG. 8, the processing operation during moving image shooting will be described.
First, the user uses the activation condition setting unit 104, the operation mode data table stored in the activation condition storage unit 103, the data table regarding the automatic selection start condition, the data table that defines the conditions for determining the number of simultaneously selected persons, Each condition is arbitrarily set from a data table in which automatic selection conditions are defined (step S101).

  Next, the control circuit 41 determines whether or not the start of moving image shooting has been instructed (step S102). If the start of moving image shooting has not been instructed ("No" in step S102), the control circuit 41 returns. stand by. On the other hand, when the start of moving image shooting is instructed (“Yes” in step S102), it is determined whether or not the end of moving image shooting is instructed (step S103).

  If the end of moving image shooting is instructed in step S103 (“Yes” in step S103), the entire process ends, and if the end of moving image shooting is not instructed (“No” in step S103) ]), The image data for the next new moving image frame is captured (step 104).

  Then, a face image is detected from the image data newly captured by the face image detection unit 101. If the face image currently being tracked exists in the current image data, the face image is detected. Tracking is continued and position information in the detection list 102 is updated. On the other hand, face images that have been tracked in the past but do not exist in the current image data are deleted from the detection list 102 (step S105). Here, tracking refers to tracking a face image detected in a previously captured moving image frame even if its position changes.

  Also, a new face image is detected from the image data (step S106), and the detected face image identification number and detection position information are added to the detection list 102 (step S107). As a new face image detection method, an image area where no face image has already been detected is targeted. First, after detecting a skin color portion, the eyes, nose, mouth, etc. are detected within the detected skin color area. It is determined whether or not there is a corresponding portion. If there is a corresponding portion, the skin color portion is regarded as a face image.

  Next, the selection control unit 48 determines whether or not the detection statuses of the plurality of face images shown in the detection list 102 match the start conditions for the automatic selection operation set by the user (step S108). If not ("No" in step S108), the process returns to step S103. On the other hand, when the detection statuses of the plurality of face images shown in the detection list 102 match the start condition of the automatic selection operation set by the user (“Yes” in step S108), the detection status is shown in the detection list 102. Based on the position information of the plurality of face images, a roulette mode operation is started in which identification display is performed while randomly changing the position of each face image at regular time intervals (step S109).

  Next, the simultaneous selection number of persons is determined based on the determination condition of the simultaneously selected number of persons set by the user (step S110), and face images for the determined number of persons are detected based on the automatic selection condition set by the user. A plurality of face images in the list 102 are selected at random. The random selection here is for giving game characteristics, and is truly random if the selection cannot be predicted by the user because the selection rule is not known to the user in advance. It is not necessary, and includes selection according to some rule (step S111). Then, in a state where the selected face image is identified and displayed, the change of the position of the face image that is randomly identified and displayed by the operation of the roulette mode started in step S109 is stopped, and the final selection result is displayed. Displayed on the unit 106 (stops in a state where the face image selected in step S111 is finally identified and displayed) (step 112), and returns to step 103.

<Specific examples of processing operations during movie shooting>
A specific example of the processing operation during moving image shooting will be described with reference to FIGS. 9 and 10.
Here, for example, there are seven people from Mr. A to Mr. G at the party venue, and at the same time as shooting the movie of the party with the camera, the image during the shooting is displayed in real time on the external monitor of the party venue Imagine a scene where you are enjoying the game.

  Each shooting frame is as shown in FIG. 9, and the automatic selection operation start condition set by the user is “(the number of all face images currently detected is 3 or more) AND (previous automatic The face image selected at the time of selection execution is no longer detected (followed)) ”, the condition for determining the number of simultaneously selected people is“ 1 (fixed) ”, and the automatic selection condition is“ currently detected (followed) ” "Randomly select from all existing face images".

  Based on the state transition diagram shown in FIG. 10 under the above conditions, a specific example in the processing operation during moving image shooting will be described. In FIG. 10, “◯” indicates a person detected (followed) in the shooting frame, and “◎” indicates a person selected most recently. Further, even if the same face image is detected (following) once, the detected face image is regarded as another face image.

  First, in the framing state (1), no person exists in the shooting frame. In the framing state (2), only Mr. A is detected in the shooting frame. In the framing state (3), Mr. B is added to this. In these states, in all of these states, the conditions for starting the automatic selection operation are “the number of all face images currently detected is 3 or more” and “previous” The automatic selection operation is not executed because the face image selected at the time of automatic selection is not cleared (because the condition is not satisfied).

  In the framing state (4), by newly adding Mr. C, the start condition of the automatic selection operation is “the number of all currently detected face images is 3 or more” and “selected during the previous automatic selection execution” "The detected face image is no longer detected (followed up)" is cleared, and the automatic selection operation is executed. In addition, the detection condition of the number of simultaneously selected persons is “one person (fixed)” and the automatic selection condition “random selection from all face images currently detected (followed)” is detected in the shooting frame. Random selection is performed among Mr., Mr. B, and Mr. C, and Mr. B is selected here.

  In the framing state (5), Mr. D is newly added, but Mr. B selected at the time of the previous automatic selection execution is still detected (following), so the start condition for the automatic selection operation is not satisfied. The automatic selection operation is not executed. In the framing state (5), Mr. A is removed and Mr. E is newly added. In this case as well, Mr. B who was selected at the time of the previous automatic selection execution is still detected (followed up). The start condition for the selection operation is not satisfied, and the automatic selection operation is not executed.

  In the framing state (7), Mr. B is further removed, so that the automatic selection operation start conditions are “the number of all currently detected face images is 3 or more” and “selected at the time of the previous automatic selection execution”. The face image is no longer detected (followed up) ”is cleared, and the automatic selection operation is executed. Further, Mr. C is selected according to the condition for determining the number of simultaneously selected persons “1 person (fixed)” and the automatic selection condition “random selection from all currently detected (followed) face images”.

  In the framing state (8), Mr. C is further removed and Mr. D and Mr. E are detected in the photographing frame. Therefore, the conditions for starting the automatic selection operation are “all currently detected”. The number of face images is 3 or more ”and“ the face image selected at the time of the previous automatic selection execution is no longer detected (followed) ”is not cleared, and the automatic selection operation is not executed.

  In the framing state (9), Mr. D is removed and Mr. F and Mr. G are newly added. Therefore, the start condition of the automatic selection operation is “the number of all face images currently detected is 3. Above ”and“ the face image selected at the time of the previous automatic selection execution is no longer detected (followed) ”are cleared, and the automatic selection operation is executed. Further, Mr. F is selected by “1 (fixed)” as the determination condition for the number of simultaneously selected persons and “random selection from all currently detected (following) face images” as the automatic selection condition.

  As in the above example, according to the present embodiment, a game can be enjoyed while watching a moving image being shot. In addition, since the automatic selection operation is activated only when a predetermined condition determined by the user is satisfied, it is possible to give excitement to those who enjoy the game. Furthermore, in the case of the condition setting as described above, since a different person is selected every time the automatic selection operation is started, there is no sense of unfairness and it is possible to enjoy without getting tired of the game. Further, in the above example, the processing operation at the time of moving image shooting has been described as an example, but even when a moving image that has already been shot is played back, it is possible to enjoy the game while watching a moving image by the same processing.

<Processing during still image playback>
With reference to FIG. 11, the processing operation at the time of still image reproduction will be described.
First, the user selects a still image (step S201). Then, a face image is detected from the selected still image (step S202). As a face image detection method, first, after detecting a skin color portion, it is determined whether or not there is a portion corresponding to eyes, nose, mouth, or the like in the detected skin color region, and there is a corresponding portion. In this case, the skin color portion is regarded as a face image. Further, the identification number of the detected face image and the detected position information are registered in the detection list 102 (step S203).

  Next, using the activation condition setting unit 104, any of the operation mode data table stored in the activation condition storage unit 103, the data table that defines the determination condition of the simultaneous selection number of persons, and the data table that defines the automatic selection condition Each condition is set to (Step S204). When the above setting is completed, the roulette operation is started (step S205).

  Then, the simultaneous selection number of persons is determined based on the determination condition of the simultaneously selected number of persons set by the user (step S206), and the face images for the determined number of persons are detected based on the automatic selection condition set by the user. The face image is selected from the face images in 102 (step S207), and the final selection result is displayed on the display unit 106 in a state where the selected face image is identified and displayed (step 208).

<Specific examples of processing operations during still image playback>
A specific example of the processing operation at the time of reproducing a still image will be described with reference to FIG.
Here, for example, there are seven persons from Mr. A to Mr. G at the party venue, and the still image data obtained by photographing these seven people is reproduced and displayed on the external monitor of the party venue. At the same time, assume that you are enjoying the game.

  Further, the shooting frame is as shown in FIG. 12, the determination condition of the simultaneous selection number set by the user is “one person (fixed)”, and the automatic selection condition is “in the face image not selected in the past”. Is the closest face image from the camera. In this case, Mr. F is selected in the first processing operation, and Mr. E is selected in the second processing operation.

  As in the above example, according to the present embodiment, it is possible to enjoy the game while viewing the still image being played back. In the case of the above condition setting, a different person is selected every time the roulette mode is activated, so that there is no sense of unfairness and it is possible to enjoy without getting tired of the game.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes a design and the like within a scope not departing from the gist of the present invention. For example, in the present embodiment, the case where the user sets the automatic selection start condition, the simultaneous selection number determination condition, and the automatic selection condition has been described as an example. A mode for setting the conditions may be provided. In this mode, conditions set by the user in the past may be learned according to the type of captured image, and conditions that meet the user's preference may be set automatically. Furthermore, for each type of captured image, a condition setting that can produce the most interesting game may be stored, and the condition may be automatically set according to this.
