As shown in FIG. 1C, the display surface of the display unit 13 is rotated toward the subject, so that the user confirms the subject image and the like in a state where the imaging unit 15 including the imaging element faces the user. can do.

  FIG. 2A is a block diagram illustrating an outline of a configuration of a display control device according to an embodiment of the present disclosure.

  As illustrated in FIG. 2A, the display control device 11 according to the embodiment of the present disclosure includes a detection unit 17. The detection unit 17 detects whether or not the display unit 13 and the imaging unit 15 have a predetermined relationship. Details of the detection unit 17 will be described later. In the present disclosure, at least one of information related to automatic recording of a subject image obtained by the imaging unit and information related to correction of the subject image obtained by the imaging unit is displayed on the display unit according to the detection result of the detection unit.

  FIG. 2B is a block diagram illustrating an example of a configuration of an imaging device to which the display control device according to the embodiment of the present disclosure is applied.

  The imaging unit 15 includes an imaging element such as a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS), and acquires an image signal related to the subject by photoelectric conversion. The image signal related to the subject acquired by the imaging unit 15 is output to the control unit 65 described later.

  The operation unit 63 includes various buttons such as the function button group 61 and the release button R described above. The operation unit 63 functions as a user interface for operating the imaging device 1. The operation unit 63 may include an external control device such as a remote controller. An operation signal received by the operation unit 63 and corresponding to a user input operation is output to the control unit 65 described later.

  The control unit 65 is a processing device including a processor, and the control unit 65 is configured as, for example, a digital signal processor (DSP) or a CPU (central processing unit). The control unit 65 controls each unit of the imaging device 1 and outputs a processing result corresponding to an input from the operation unit 63, for example.

  The control unit 65 includes, for example, a display control unit 19, an image processing unit 67, an image recording unit 69, a shooting mode control unit 73, a face detection unit 75, a smile shooting control unit 77, and a skin color adjustment unit 79. Hereinafter, the display control unit 19, the image processing unit 67, the image recording unit 69, the shooting mode control unit 73, the face detection unit 75, the smile shooting control unit 77, and the skin color adjustment unit 79 will be described in order.

  The display control unit 19 performs display control for displaying various data on the display unit 13. As an example of data displayed on the display unit 13, image data related to a subject obtained by the imaging unit 15 can be given. By sequentially displaying the image data related to the subject on the display unit 13, the user can check the current state of the subject with reference to the display unit 13.

  Other examples of data displayed on the display unit 13 include icons indicating the remaining battery level, setting values of parameters used for photographing, and the like. Examples of parameters used for shooting include the presence / absence of a strobe, shutter speed, aperture opening, ISO sensitivity, and the like. The parameters used for shooting include parameters used for shooting including the user who operates the imaging apparatus 1 as a subject (hereinafter referred to as self-portrait shooting as appropriate). As will be described later, examples of parameters used for self-portrait photographing include self-timer and face detection, so-called “smile shutter”, so-called “skin color correction”, and the like.

  The image processing unit 67 performs predetermined signal processing on the image signal related to the subject output from the imaging unit 15 and outputs the image signal after the signal processing. Examples of signal processing for an image signal related to a subject include digital gain adjustment, gamma correction, color correction, and contrast correction.

  The image recording unit 69 compresses the image signal after the signal processing output from the image processing unit 67 by a compression encoding method such as JPEG (Joint Photographic Experts Group), and outputs the compressed data. The image data output from the image recording unit 69 is stored in the storage device 71, for example.

  The storage device 71 includes, for example, an external storage device that can be freely attached to and detached from the imaging device 1 and an internal storage device that is fixed inside the main body. Image data obtained by shooting is stored in the storage device 71. Whether the image data is stored in the external storage device or the internal storage device can be arbitrarily set by the user, for example.

  Note that a program for performing various arithmetic processes and controlling each unit of the imaging apparatus 1 is, for example, a RAM (Random Access Memory) and a ROM (Read-Only Memory) disposed in the control unit 65, or a control unit 65. Stored in the storage device 71 connected to the. Examples of the storage device 71 include a hard disk, a flash memory, an optical disk, a magneto-optical disk, and an MRAM (Magnetoresistive Random Access Memory).

  The shooting mode control unit 73 performs control for recording image data according to the shooting mode selected by the user. Examples of the shooting mode setting include single shooting (recording of image data for each frame), continuous shooting, and shooting using a self-timer.

  The face detection unit 75 detects a specific target from the image data related to the subject acquired by the imaging unit 15 by, for example, pattern matching. Here, the specific target is, for example, the face of a person or animal included in the subject. Therefore, the face detection unit 75 detects one or more faces included in the image data regarding the subject.

  The user can set face detection by an input operation on the operation unit 63, and the user can select ON or OFF as the face detection setting value.

  The smile photographing control unit 77 determines whether or not the face detected by the face detection unit 75 is a smile. The smile photographing control unit 77 performs control for automatically executing recording of image data when the face detected by the face detection unit 75 is a smile. The function of automatically recording image data in accordance with the determination result of whether or not the subject is smiling is called “smile shutter”.

  The user can set “smile shutter” by an input operation on the operation unit 63, and the user can select on or off as the set value of “smile shutter”. When “ON” is selected as the setting value of “SMILE SHUTTER”, the user can further set how much the subject is smiling to record the image data. Specifically, for example, the user can further set “Laughter”, “Normal laughter”, “Smile” or the like as the set value of “Smile shutter”.

  The skin color adjustment unit 79 corrects the recorded image data so that the skin of the person looks smooth. The correction of the image data relating to the skin of the person's face, in particular, the skin of the person is called “skin color correction” or the like. That is, for example, the skin color adjustment unit 79 performs image processing on the data relating to the human face detected by the face detection unit 75 to record the photographed person's skin so that the skin looks smooth. Correct the image data. Specifically, the skin color adjustment unit 79 performs noise removal on data relating to a person's face.

  The user can set “skin color correction” by an input operation on the operation unit 63, and the user can select ON or OFF as the setting value of “skin color correction”. When ON is selected as the setting value of “skin color correction”, the user can further set the degree of “skin color correction”. Specifically, for example, the user can further set “strong”, “medium”, or “weak” as “skin color correction”.

(1-1-1. Configuration Example of Detection Unit)
Next, a configuration example of the detection unit 17 and an example of the operation of the detection unit 17 will be described. As described above, the detection unit 17 detects whether or not the display unit 13 and the imaging unit 15 are in a predetermined relationship.

  Here, the predetermined relationship indicates, for example, the relative positional relationship between the display unit 13 and the imaging unit 15. Specifically, for example, the detection unit 17 detects whether or not both the display surface of the display unit 13 and the imaging surface of the imaging element are directed toward the subject. That is, the predetermined relationship is a relationship in which the subject can confirm the display content of the display unit 13. Therefore, for example, when the display unit 13 is rotatable with respect to the housing 10 of the main body 1b, the detection unit 17 detects the rotation angle of the display 13 with respect to the housing 10 of the main body 1b, Detect the display direction.

  When the display unit 13 is rotated or moved with respect to the housing 10 of the main body unit 1b, the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are both directed toward the subject. Therefore, it can be determined that the photographer wants to shoot with the subject included. Therefore, in the present disclosure, based on whether or not the display unit and the imaging unit are in a predetermined arrangement, it is estimated whether or not the user is going to perform shooting that includes himself / herself as a subject.

  3A and 3B are schematic diagrams illustrating an example of a configuration of a detection unit in an imaging device to which the display control device according to the embodiment of the present disclosure is applied. FIG. 3A is a diagram illustrating a back surface of the imaging device 1 to which the display control device 11 according to the embodiment of the present disclosure is applied. FIG. 3B is a diagram illustrating a left side view of the imaging device 1 to which the display control device 11 according to the embodiment of the present disclosure is applied.

  As shown in FIGS. 3A and 3B, the detection unit 17 is configured by a set of a magnetic field sensor 17a and a magnet 17b, for example. The magnetic field sensor 17a is disposed, for example, inside the housing 10 of the main body 1b, and the magnet 17b is disposed, for example, inside the display unit 13. Of course, the magnetic field sensor 17a may be disposed inside the display unit 13, and the magnet 17b may be disposed inside the housing 10 of the main body unit 1b.

  The magnetic field sensor 17a is a sensor including a Hall element, for example. The magnetic field sensor 17a includes a digital output type sensor that outputs a logical value corresponding to the presence or absence of a magnetic field (in this specification, “magnetic flux density” and “magnetic field” are not distinguished), a magnetic field sensor There is an analog output type sensor that outputs a signal proportional to the size. If it is possible to detect whether or not the display unit 13 and the imaging unit 15 are in a predetermined arrangement, either a digital output type or an analog output type may be used as the magnetic field sensor 17a.

  Now, assuming that the user is shooting a subject that does not include himself / herself, the imaging surface of the image sensor is directed toward the subject, and the user's face and the display unit 13 on the opposite side to the imaging surface are displayed. Opposite to the display surface. In other words, the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially antiparallel. In FIG. 3B, the display direction of the display unit 13 is schematically indicated by an arrow D3, and the imaging direction of the imaging unit 15 is schematically indicated by an arrow D5.

  FIG. 3C is a left side view illustrating a state in the middle of rotation of the display unit with respect to the housing of the main body unit.

  When the display unit 13 is rotated with respect to the housing 10 of the main body unit 1b so that the display surface of the display unit 13 faces the subject as indicated by an arrow E in FIG. The magnet 17b also moves. Then, with the movement of the magnet 17b, the magnetic field near the magnetic field sensor 17a also changes as the display unit 13 rotates.

  FIG. 4A is a front view showing a state in which both the display surface of the display unit and the imaging surface of the imaging device are directed toward the subject. FIG. 4B is a top view illustrating a state in which both the display surface of the display unit and the imaging surface of the imaging element are directed toward the subject. FIG. 4C is a left side view illustrating a state in which both the display surface of the display unit and the imaging surface of the imaging element are directed toward the subject.

  In FIG. 4C, the display direction of the display unit 13 is schematically indicated by an arrow D3, and the imaging direction of the imaging unit 15 is schematically indicated by an arrow D5. As shown in FIG. 4C, in a state where both the display surface of the display unit 13 and the imaging surface of the image sensor are directed toward the subject, the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially the same. It is parallel.

  Here, for example, if the magnetic moment of the magnet 17b is parallel to the display direction of the display unit 13 (the direction indicated by the arrow D3), the state shown in FIG. 4C is compared with the state shown in FIG. 3B. Thus, the direction of the magnetic field in the vicinity of the magnetic field sensor 17a is reversed. Therefore, the polarity of the output from the magnetic field sensor 17a is reversed, and the control unit 65 causes both the display surface of the display unit 13 and the imaging surface of the image sensor to be directed toward the subject from the polarity of the output from the magnetic field sensor 17a. It can be determined whether or not. In other words, the control unit 65 can determine based on the detection result of the detection unit 17 whether or not shooting including the user who operates the imaging device 1 as a subject is being performed.

  In the example described above, the rotation of the display unit 13 with respect to the housing 10 is detected due to the change of the magnetic field. However, the method for detecting the rotation and movement of the display unit 13 with respect to the housing 10 is not limited to this example. For example, when the display unit 13 is rotatably connected to the housing 10 by a rotating arm or the like, how much the display unit 13 is rotated with respect to the housing 10 by detecting the rotation angle of the rotating arm. It may be determined whether or not. Alternatively, for example, an electrical contact is provided on the housing 10 and the display unit 13, or a notch is provided on one of the housing 10 or the display unit 13 to detect contact of the display unit 13 with the housing 10. It may be.

(1-1-2. Example of image displayed on display unit)
FIG. 5A is an image diagram illustrating an example of an image displayed on the display unit in a state where the display direction of the display unit and the imaging direction of the imaging unit are substantially antiparallel.

  In a state where the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially antiparallel, the subject image acquired by the imaging device and various parameters used for imaging, for example, One or more icons indicating setting values are displayed on the display unit 13. FIG. 5A shows an example in which an icon C1 indicating the remaining battery level, an icon C2 indicating that the imaging apparatus 1 is in the shooting mode, and the like are displayed on the display unit 13.

  FIG. 5B is an image diagram illustrating another example of an image displayed on the display unit in a state where the display direction of the display unit and the imaging direction of the imaging unit are substantially antiparallel.

  In FIG. 5B, an icon C0 indicating the setting value of the strobe, an icon S0 indicating the setting value of the self-timer, an icon S1 indicating the setting value of face detection, an icon S2 indicating the setting value of “smile shutter”, and “skin color correction” An example in which an icon S3 indicating a setting value is further displayed on the display unit 13 is shown. In the example shown in FIG. 5B, strobe light emission, self-timer and “smile shutter” are turned off, and face detection is turned on. The degree of “skin color correction” is set to “medium”. In this way, setting values of parameters used for self-portrait photography may be further displayed on the display unit.

  As shown in FIGS. 5A and 5B, the display unit 13 displays a part or all of icons indicating setting values of various parameters. In general, the display format in the imaging apparatus 1 can be switched so that the user can adjust the amount of information regarding various parameters. That is, in the imaging apparatus 1, it is possible to switch between the display format as shown in FIG. 5A and the display format as shown in FIG. 5B, for example, by operating the function button group 61 and the like. ing.

  Here, in a state where the display direction of the display unit and the imaging direction of the imaging unit are substantially anti-parallel (the state shown in FIGS. 1A and 1B), the user includes the user himself / herself as a subject. Suppose that the image pickup surface of the image pickup device is directed to the user side.

  Then, since the display surface of the display unit comes to the back side of the imaging device as viewed from the user, the user can check the setting values of various parameters by imaging the user so that the display surface of the display unit faces the user. The device must be turned over one by one. Further, a group of function buttons used for changing setting values of various parameters is generally arranged on the back surface of the imaging apparatus. Therefore, the conventional imaging apparatus is difficult to handle when it is necessary to change the setting values of various parameters. As described above, when shooting with the user himself / herself included in the subject, the user needs to set the setting values of various parameters in advance and direct the imaging surface of the imaging device to himself / herself.

  Therefore, in the present disclosure, based on whether or not the display unit and the imaging unit are in a predetermined arrangement, it is estimated whether or not the user is going to shoot to include himself / herself in the subject, and various parameters are set. The set value is displayed on the display unit. At this time, the display control apparatus 11 according to the present disclosure causes the display unit 13 to display, for example, an icon indicating a parameter setting value used for self-portrait photographing among one or more icons indicating the setting values of various parameters. .

  FIG. 6A is an image diagram illustrating an example of an image displayed on the display unit in a state where the display direction of the display unit and the imaging direction of the imaging unit are substantially parallel to each other.

  In the present disclosure, when the user directs the display surface of the display unit to himself, the display format of the image displayed on the display unit is automatically changed. That is, for example, when the user directs the display surface of the display unit toward himself with the image pickup surface of the image sensor facing himself / herself, the image displayed on the display unit is changed to, for example, the image illustrated in FIG. 6A.

  In a state where the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially parallel, for example, information related to processing for an image obtained by the imaging unit 15 is displayed on the display unit 13. As processing for an image obtained by the imaging unit 15, for example, processing relating to automatic recording of a subject image obtained by the imaging unit 15, processing relating to correction of a subject image obtained by the imaging unit 15, and an image obtained by the imaging unit 15 For example, a process for detecting a specific target is included. The information related to the automatic recording of the subject image obtained by the imaging unit 15 is executed according to the determination result of whether or not the subject is smiling, such as a setting value of automatic recording by a self-timer and “smile shutter”. Set value for automatic recording. Examples of the information regarding the correction of the subject image obtained by the imaging unit 15 include a setting value of “skin color correction”. Examples of the detection of the specific target from the subject image obtained by the imaging unit 15 include face detection.

  More specifically, when the user directs the display surface of the display unit 13 to himself / herself, as shown in FIG. 6A, for example, an icon S1 indicating a setting value for face detection, and an icon indicating a setting value for “smile shutter” Icons S3 and the like indicating the setting values of S2 and “skin color correction” are displayed on the display unit 13. FIG. 6A shows an example in which an icon S1 indicating the face detection setting value, an icon S2 indicating the “smile shutter” setting value, and an icon S3 indicating the “skin color correction” setting value are displayed on the display unit 13. The image displayed on the display unit 13 is not limited to this example. For example, the number, type, arrangement, and the like of icons displayed on the display unit 13 may be arbitrarily set by the user.

  In particular, an icon indicating the setting value of a parameter used for photographing a person is displayed on the display unit 13, so that the user can set the parameter used for self-portrait photographing without turning the imaging device 1 over. The value can be confirmed. Thus, in the state where the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially parallel, an icon indicating the setting value of the parameter used for photographing the person is displayed on the display unit 13. It is preferably displayed.

[1-2. Example of processing in display control apparatus]
FIG. 6B is a flowchart illustrating an example of processing in the display control apparatus according to the embodiment of the present disclosure. A series of processing described below with reference to FIG. 6B is executed by, for example, the control unit.

  First, in step St1, it is determined whether or not the display unit 13 and the imaging unit 15 have a predetermined relationship. That is, based on the detection result of the detection unit 17, for example, it is determined whether or not the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially parallel. If it is not detected that the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially parallel, the process ends.

  On the other hand, when the detection unit 17 detects that the display direction of the display unit 13 and the imaging direction of the imaging unit 15 are substantially parallel, the process proceeds to step St2. Then, in step St2, for example, parameter setting values used for self-portrait photographing are read. The set values of various parameters are stored, for example, in an internal storage device fixed inside the main body 1b.

  When the reading of the parameter setting values is completed, the process proceeds to step St3. In step St3, the display format of the image displayed on the display unit 13 is changed. That is, for example, the image displayed on the display unit 13 is changed from the image shown in FIG. 5A to the image shown in FIG. 6A.

  At this time, as shown in FIG. 6A, an icon corresponding to each set value is displayed on the display unit 13. Therefore, the user refers to each icon displayed on the display unit 13, for example, the face detection setting value is turned on, the “smile shutter” setting value is turned off, and the degree of “skin color correction” is set. It can be easily confirmed that is set to “medium”.

  As described above, according to the first embodiment of the present disclosure, the display format of the image displayed on the display unit 13 is automatically changed when the user directs the display surface of the display unit 13 to himself / herself.

  For example, when the user performs self-portrait shooting, the display surface of the display unit is directed toward the user. However, in a state where the display surface of the display unit is directed toward the user, the imaging device shakes and the user captures the image well. May not be possible. Therefore, for example, the user performs shooting after making settings for self-portrait shooting such as a self-timer in advance with respect to the imaging apparatus. In this case, the user needs to make various settings before changing the display direction of the display unit.

  If the user performs various settings before changing the display direction of the display unit, whether or not shooting by the self-timer is enabled while checking the own image displayed on the display unit, etc. There are situations where the user wants to check the setting values of various parameters. At this time, the user cannot simply confirm the setting values of the various parameters simply by directing the display surface of the display unit toward the user. In order for the user to check the setting values of various parameters, the user must call a display screen on which the setting values that the user needs to check are displayed, for example, by performing a menu operation or a display format switching operation. Because.

  For this reason, in the conventional imaging apparatus, in order for the user to switch the display format, the user has to operate the buttons arranged on the back surface of the imaging apparatus while keeping a pose. Alternatively, the user has to break the pose, return the display direction of the display unit to the original direction, and operate these buttons while visually recognizing the buttons arranged on the back of the imaging device.

  In the present disclosure, the detection unit detects that the display direction of the display unit has been changed by the user, and is used for shooting including, for example, the user who operates the imaging apparatus as a subject according to the detection result of the detection unit. The parameter setting value is displayed on the display. Therefore, whether the setting value of a parameter used for shooting is a setting suitable for shooting including the user who operates the imaging apparatus as a subject with the display surface of the display unit facing the user. It can be easily confirmed whether or not. Therefore, according to the present disclosure, the user can easily perform self-portrait shooting without the need for manipulating the buttons on the back of the imaging apparatus or breaking the pose.

  In FIG. 6A, when the user points the display surface of the display unit 13 to himself / herself, parameters used for self-portrait shooting among one or more icons indicating setting values of various parameters used for shooting. An example in which an icon indicating the set value is displayed on the display unit 13 is shown. As described above, among the one or more icons indicating the setting values of various parameters used for shooting, the icon indicating the setting value of parameters used for self-portrait shooting may be displayed with priority.

  The number of icons displayed on the display unit 13 is preferably five or less, and more preferably three. This is because if the number of icons displayed on the display unit 13 is large, it becomes easy for the user to check the setting values of various parameters, but the display on the screen becomes complicated and it is difficult for the user to check the subject image. When the number of icons displayed on the display unit 13 is about three, the image displayed on the display unit 13 is not complicated and the balance of the information amount is good.

  When the user faces the display surface of the display unit 13 toward himself, for example, the image displayed on the display unit 13 may be changed from the image shown in FIG. 5A to the image shown in FIG. 5B. Of course it does not matter. In this way, the amount of information displayed on the display unit 13 may be adjusted according to the user's needs.

<2. Second Embodiment>
[2-1. Schematic configuration of imaging apparatus]
FIG. 7A is a rear view illustrating an example of an imaging apparatus to which the display control apparatus according to the second embodiment is applied. FIG. 7B is a schematic diagram illustrating a state in which the display surface of the display unit of the imaging apparatus illustrated in FIG. 7A faces the subject.

  As illustrated in FIGS. 7A and 7B, the imaging device 2 to which the display control device 21 according to the second embodiment is applied includes, for example, a main body 2b and a lens unit 2r. An imaging unit 25 including an imaging element is arranged inside the housing 20 of the main body 2b, and for example, a group of function buttons and a display unit 23 are arranged on the back of the main body 2b of the imaging device 2. The imaging device 2 according to the second embodiment is common to the imaging device 1 according to the first embodiment. In addition, according to the detection result of the detection unit 27, at least one of information related to automatic recording of the subject image obtained by the imaging unit 25 and information related to correction of the subject image obtained by the imaging unit 25 is displayed on the display unit 23. Thus, the second embodiment is common to the first embodiment.

  The second embodiment is different from the first embodiment in that the display unit 23 has a function of an input device that receives an instruction from a user. That is, the display unit 23 in the second embodiment is specifically configured as a touch panel, and thus the display unit 23 also functions as the operation unit 63 described above.

  In the second embodiment, according to the detection result of the detection unit 27, for example, one or more icons indicating the setting values of parameters used for self-portrait shooting are displayed on the display unit 23. The second embodiment is different from the first embodiment in that the user touches these icons displayed on the display unit 23 to execute functions corresponding to the contents displayed by the individual icons. Yes.

[2-2. Outline of operation of imaging apparatus]
As shown in FIG. 7A, in the state where the display direction of the display unit 23 and the imaging direction of the imaging unit 25 are substantially antiparallel, for example, subject images acquired by the imaging device, One or more icons indicating parameter setting values are displayed on the display unit 23. Alternatively, for example, setting values of parameters used for photographing including the user who operates the imaging device 2 as a subject are further displayed on the display unit 23.

  Here, when the display surface of the display unit 23 is rotated by the user with respect to the housing 20, for example, the detection unit 27 configured by a set of the magnetic field sensor 27 a and the magnet 27 b is connected to the display unit 23 and the imaging unit 25. Is detected to have a predetermined relationship. Then, as in the case of the first embodiment, the display format of the display unit 23 is changed, and information regarding automatic recording of the subject image obtained by the imaging unit 25 or information regarding correction of the subject image is displayed on the display unit 23. The Specifically, as shown in FIG. 7B, for example, an icon S21 indicating a setting value for face detection, an icon S22 indicating a setting value for “smile shutter”, an icon S23 indicating a setting value for “skin color correction”, and the like. It is displayed on the display unit 23.

  As described above, in the second embodiment, the display unit 23 is configured as a touch panel. When the user's touch on the icons S21 to S23 displayed on the display unit 23 is detected, the display control device 21 according to the second embodiment, for example, displays the screen displayed on the display unit 23 using individual icons.

Therefore, the user can change the setting corresponding to the process indicated by each of the icons S21 to S23 by touching each of the icons S21 to S23 displayed on the display unit 23 during self-portrait shooting. .

  Note that, for example, an icon different from one or more icons initially displayed on the display unit 23 when the display surface of the display unit 23 is directed to the user by a so-called “flick” operation or a tracing operation by the user is displayed on the display unit. 23 may appear. For example, when the user traces the vicinity of the icons S21 to S23 displayed on the display unit 23 downward, the icons S21 to S23 may change so as to flow downward. In this case, for example, an icon S23 indicating the setting value of “skin color correction” is hidden at the bottom of the screen by the user's tracing operation, and for example, an icon indicating the setting value of the self-timer appears from the top of the screen. In this way, the user can easily change the setting values of various parameters used for shooting.

  FIG. 8A is an image diagram illustrating an example of a setting screen displayed when the user touches an icon displayed on the display unit.

  FIG. 8A is a diagram illustrating a state after the user touches the icon S <b> 22 displayed on the display unit 23. When the user touches the icon S22 displayed on the display unit 23, as shown in FIG. 8A, for example, the screen displayed on the display unit 23 is a screen for changing settings corresponding to the process indicated by the icon S22. Transition to.

  In FIG. 8A, an icon Sa22 for setting the “smile shutter” setting value to “big laughter”, an icon Sb22 for setting the setting value “normal laughter”, an icon Sc22 for setting the setting value “smile”, The icon Sd22 for turning off the setting value and the icon Se22 for closing the setting screen are displayed. For example, the user can switch the setting value of the process indicated by the icon S22, that is, the setting value of “smile shutter” by touching any of the icons Sa22, Sb22, Sc22 or the icon Sd22.

  FIG. 8A shows a state in which OFF is selected as the setting value of “smile shutter”. For example, after “OFF” is selected as the setting value of “SMILE SHUTTER”, when the user touches the icon Se22 for closing the setting screen, the setting of “SMILE SHUTTER” is determined to be OFF and the setting screen is closed. It is done.

  Note that when the user's touch on the icons S21 to S23 is detected, the screen displayed on the display unit 23 is changed to the setting screen, and the setting corresponding to the process indicated by each icon is changed. You may do it. That is, among the icons S21 to S23 displayed on the display unit 23, for example, every time the icon S23 is touched by the user, the setting value of “skin color correction” is OFF → “weak” → “medium” → “strong”. “→ Off →... May be switched. In this case, for example, the user can switch the setting value of the process indicated by the icon S23, that is, the setting value of “skin color correction” by repeatedly touching the icon S23.

[2-3. Example of processing in display control apparatus]
FIG. 8B is a flowchart illustrating an example of processing executed by touching an icon displayed on the display unit. In FIG. 8B, it is assumed that the display unit 23 and the imaging unit 25 have a predetermined relationship. A series of processing described below with reference to FIG. 8B is executed by, for example, the control unit.

  First, in step St21, it is determined whether or not the user has touched the display unit 23 configured as a touch panel. If it is not detected that the user has touched the display unit 23, the process ends.

  On the other hand, when the detection unit 27 detects that the user has touched the display unit 23, the process proceeds to step St22. In step St <b> 22, it is determined in which of the display areas of the display unit 23 the touch by the user has been detected. That is, it is determined which icon the user has touched among the icons S21 to S23 displayed on the display unit 23. In the following, it is assumed that a variable for designating an area (which may be referred to as coordinates) in which each of the icons S21 to S23 is displayed is U, and for the area in which the icons S21, S22, and S23 are displayed, Assume that “a”, “b”, and “c” are set as values.

  For example, when the icon S21 displayed on the display unit 23 is touched by the user, the screen displayed on the display unit 23 is changed to a screen for changing the face detection setting in step St23. . For example, when the icon S22 displayed on the display unit 23 is touched by the user, the screen displayed on the display unit 23 is changed to a screen for changing the setting of “smile shutter” in step St24.

An imaging unit 35 including an imaging device is arranged inside the housing 30 of the main body 3b, and a group of function buttons and a display unit 33 are arranged on the back of the main body 3b of the imaging device 3, for example. The imaging device 3 according to the third embodiment is common to the imaging device 1 according to the first embodiment. In addition, according to the detection result of the detection unit 37, the information about the automatic recording of the subject image obtained by the imaging unit 35 or the information about the correction of the subject image is displayed on the display unit 33. Common to the first embodiment.

  The third embodiment is different from the first embodiment in that the display unit 33 is a display unit including one or more function buttons 34. In the third embodiment, according to the detection result of the detection unit 37, each of the one or more function buttons 34 arranged on the display unit 33 has a function corresponding to information regarding processing on an image obtained by the imaging unit 35. It is different from the first embodiment in that it is assigned.

[3-2. Outline of operation of imaging apparatus]
In the example illustrated in FIG. 10A, four function buttons 34 a to 34 d are arranged on the display unit 33. In a state where the display direction of the display unit 33 and the imaging direction of the imaging unit 35 are substantially anti-parallel, the function buttons 34 a to 34 d are similar to the group of function buttons on the back of the housing 30. For example, functions such as menu operation and selection of a shooting mode according to the scene are assigned.

  Here, when the user rotates the display surface of the display unit 33 with respect to the housing 30, for example, the detection unit 37 configured by a set of the magnetic field sensor 37 a and the magnet 37 b includes the display unit 33 and the imaging unit 35. Assume that a predetermined relationship is detected. Then, as in the case of the first embodiment, the display format of the display unit 33 is changed, and information related to processing on the image obtained by the imaging unit 35 is displayed on the display unit 33. Specifically, as shown in FIG. 10B, for example, an icon S31 indicating a setting value for face detection, an icon S32 indicating a setting value for “smile shutter”, an icon S33 indicating a setting value for “skin color correction”, and the like. It is displayed on the display unit 33. At this time, each of the icons S31 to S33 is displayed in the vicinity of the function buttons 34a to 34c.

  In the third embodiment, in addition to changing the display format of the display unit 33, the function realized by operating the function buttons 34a to 34c arranged on the display unit 33 is a parameter used for self-portrait shooting. Changed to function related to settings.
