Description

  The present invention relates to an electronic device, a control method thereof, a program, and a storage medium, and more particularly to display control in accordance with opening / closing and a posture of a display unit in an electronic device including a plurality of display units.

  In general, an electronic apparatus that includes a plurality of display units and is capable of changing the positional relationship between the plurality of display units is known. For example, there is an electronic device in which a first display unit and a second display unit are rotatably connected, and an imaging surface is provided on the opposite side of the display surface of the first display unit. In such an electronic apparatus, it is possible to display different information on each display unit for comparison. When the electronic apparatus has a camera function, it is possible to display a through image on one display unit at the time of shooting and display a shooting setting value on the other display unit. As described above, in an electronic device including a plurality of display units, user convenience can be improved.

  Furthermore, in an imaging device which is one of electronic devices, a display image of an image obtained by photographing according to the detection result by detecting a mutual positional relationship between a plurality of display units and a playback image at the time of playback There is one that controls the switching of the display.

  For example, there is an imaging apparatus including a first display unit disposed on the opposite side of the imaging surface and a second display unit rotatably disposed so as to protrude from the upper surface of the housing. In this imaging apparatus, the rotation angle is detected and whether or not a user is present on the back side of the imaging apparatus is detected. And the display content displayed on the 1st and 2nd display part is controlled according to the detection result (refer patent document 1).

JP 2010-4109

  Since the electronic device described above includes a plurality of display units, power consumption increases as the number of display units increases. In addition, a display unit that performs preferential display may be switched according to a posture of a user holding the electronic device. For this reason, the user may have to switch the display content to a display unit that performs display preferentially as necessary.

  In the imaging device described in Patent Literature 1, it is possible to control the display content of the display unit according to the rotation angle of the display unit and the presence or absence of the user. However, in the method described in Patent Document 1, when the inside of the image pickup is set at a so-called vertical position or when set upside down, the display contents may not be appropriately controlled.

  Therefore, an object of the present invention is to appropriately control display contents displayed on a plurality of display units, and to reduce power consumption without impairing user convenience, a control method thereof, and It is to provide a program and a storage medium.

  In order to achieve the above object, an electronic device according to the present invention has a first display unit having a first display surface and a positional relationship between the first display surface and the first display surface. Second display means having a changeable second display surface, first detection means for detecting a positional relationship between the first display surface and the second display surface, and the first display surface Alternatively, depending on the combination of the second detection means for detecting the posture of the second display surface with respect to the direction of gravity, the position detection result in the first detection means and the posture detection result in the second detection means, And control means for controlling operations of the first display means and the second display means.

  ADVANTAGE OF THE INVENTION According to this invention, the display content displayed on a some display part (display means) can be controlled appropriately, and it can reduce power consumption, without impairing a user's convenience.

  Hereinafter, an example of an electronic device according to an embodiment of the present invention will be described with reference to the drawings. In the following description, an imaging apparatus which is one of electronic apparatuses will be described as an example.

[First Embodiment]
FIG. 1 is a perspective view showing an appearance of an example of an imaging apparatus according to the first embodiment of the present invention. FIG. 1A is a perspective view showing a state where the imaging apparatus is viewed from the back side, and FIG. 1B is a perspective view showing a state where the imaging apparatus is viewed from the front side. Here, the subject side is defined as the front side in the optical axis direction of the photographing lens described later. The vertical and horizontal directions are based on a user located on the back side (rear side) of the imaging apparatus.

  An illustrated imaging apparatus (hereinafter referred to as a camera) 100 includes an imaging apparatus body (hereinafter referred to as a camera body) 101, and a hinge mechanism 105 extending in a predetermined direction is defined in the camera body 101. A first display unit 102 is attached to the camera body 101 by a hinge mechanism 105 so as to be rotatable (openable and closable). A second display unit 103 is disposed on one surface (front surface) of the camera apparatus main body 101. In addition, a photographing lens 104 is disposed on the back side of the first display unit 102.

  The first display unit 102 is rotatable by a hinge mechanism 105 from a predetermined “fully closed position” to a “fully opened position” about the axis C1 (first axis). Here, the “fully closed position” refers to a position where the first display unit 102 approaches or contacts the second display unit 103. The “fully opened position” refers to a position where the first display unit 102 is rotated 180 degrees in the opening direction from the “fully closed position”. That is, the first display unit 102 can be rotated 180 degrees from the “fully closed position”. Note that the rotation angle from the “fully closed position” is θc1.

  In the first embodiment, the first display unit 102 corresponds to the first display unit, and the second display unit 103 corresponds to the second display unit.

  FIG. 2 is a block diagram showing a system configuration of the camera shown in FIG.

  The camera 100 includes a system control unit 150 that controls the entire camera 100. Here, the system control unit 150 is connected to the image processing unit 107, the recording medium 108, the operation unit 109, the open / close detection sensor 110, the attitude detection sensor 111, the first display unit 102, and the second display unit 103, Each of these blocks is controlled.

  Various programs executed by the system control unit 150 are stored in a nonvolatile memory 151 such as a ROM, and the volatile memory 152 such as a RAM is used as a working memory for the system control unit 150.

  The camera 100 includes an image sensor 106, and the image sensor 106 generates an electrical signal (analog signal) corresponding to a subject image (optical image) incident through the photographing lens 104 by photoelectric conversion. Then, the image sensor 106 outputs the analog signal to the image processing unit 107 as image data by A / D conversion. Note that the image sensor 106 is constituted by, for example, a CCD or a CMOS image sensor.

  The image processing unit 107 performs predetermined image processing such as gamma / knee processing, filter processing, and monitor display information combining processing on the image data. Further, the image processing unit 107 may perform image data compression processing such as JPEG.

  The recording medium 108 is, for example, a flash memory that can be attached to and detached from the camera body 101. The recording medium 108 records image data obtained by shooting, shooting information related to shooting, and the like. The operation unit 109 includes an operation member such as a photographing switch and a touch panel. A user operates the operation unit 109 to give various commands to the system control unit 150.

  The open / close detection sensor 110 is disposed in or near the hinge mechanism 105 and detects an angle θc1 formed by the first display unit 102 and the second display unit 103. That is, the open / close detection sensor 110 outputs a position detection result indicating the open / close position of the first display unit 102. The open / close detection sensor 110 includes a single or a plurality of contact switches. The open / close detection sensor 110 may be a non-contact detection unit using a hall element, a photo interrupter, or the like.

  In the illustrated example, the system control unit 150 determines the rotation state of the first display unit 102 based on the output (detection result) of the open / close detection sensor 110. For example, the system control unit 150 determines first to third rotation states as the rotation state of the first display unit 102. The first rotation state refers to a state where the angle θc1 is not less than 0 degrees and less than 15 degrees (this state is also referred to as a fully closed position). The second rotation state refers to a state where the angle θc1 is not less than 15 degrees and less than 170 degrees (hereinafter also referred to as “transition position”). The third rotation state is a state where the angle θc1 is 170 degrees or more and 180 degrees (this state is also referred to as a fully opened position).

  The transition position is a position within a predetermined angle range corresponding to an intermediate position between the fully closed position and the fully open position.

  The posture detection sensor 111 detects the posture of the first display unit 102 or the second display unit 103 with respect to the direction of gravity and obtains a posture detection result. Here, as the posture detection sensor 111, for example, a rotation posture detection element is used to detect a change in posture when the first display unit 102 rotates about the axis C1. Note that as the posture detection sensor 111, for example, another device capable of detecting a posture change such as an acceleration sensor or a gyro sensor may be used.

  Each of the first display unit 102 and the second display unit 103 is, for example, a TFT liquid crystal panel of about 3.0 inches. Specifically, the first display unit 102 is a 3.5-inch wide TFT liquid crystal panel, and the second display unit 103 is a 3.0-inch TFT liquid crystal panel with a touch panel function.

  FIG. 3 is a perspective view for explaining an imaging posture when imaging is performed using the camera 100 shown in FIG. FIG. 3A is a diagram illustrating an example of the imaging posture, and FIG. 3B is a diagram illustrating another example of the imaging posture.

  In the imaging posture shown in FIG. 3A, the hinge mechanism 105 is rotated to the “transition position” where the angle θc1 is 120 degrees. That is, the first display unit 102 is rotated at an angle θc1 of 120 degrees. On the other hand, in the imaging posture shown in FIG. 3B, the hinge mechanism 105 is rotated to the “fully open position” where the angle θc1 is 180 degrees. That is, the first display unit 102 is in the “fully open position”.

  At this time, the camera 100 is held in a horizontal position so that the hinge mechanism 105 is positioned at a lower position with respect to the first display unit 102 in both of the imaging postures illustrated in FIGS. 3A and 3B. It is in a state. In the following description, the illustrated imaging posture is referred to as “first posture (posture 1)”.

  Then, from “posture 1”, a state in which the camera 100 is tilted approximately 90 degrees so that the right hand is in the upper position and the left hand is in the lower position so that the camera 100 is in the vertical position is “second posture (posture 2”). ) ". A state in which the camera 100 is tilted approximately 90 degrees so that the camera 100 is in the vertical position so that the left hand is in the upper position and the right hand is in the lower position is referred to as a “third posture (posture 3)”. Furthermore, a state in which the camera 100 is rotated approximately 180 degrees and held in the horizontal position so that the right hand and the left hand are switched from “posture 1” is referred to as “fourth posture (posture 4)”.

  FIG. 4 is a diagram illustrating an example of control according to the combination of the rotation state and the imaging posture described in FIG. FIG. 5 is a diagram illustrating the state of the camera 100 according to the combination of the imaging posture, the transition position, and the fully open position described with reference to FIG. In FIG. 5, the angle θc1 is 120 degrees as an example of the “transition position”, and the angle θc1 is 180 degrees as an example of the “fully open position”.

  First, referring to FIG. 4, “all off” means a state in which both the first display unit 102 and the second display unit 103 are turned off. Here, regardless of the imaging posture, in the case of the “fully closed position” where the angle θc1 is 0 degree or more and less than 15 degrees, the user can hardly confirm the first display unit 102 and the second display unit 103. As a result, the system control unit 150 performs “all extinction” control. That is, the system control unit 150 stops the operations of the first display unit 102 and the second display unit 103.

  “State priority control” is control for giving priority to the first display unit 102 or the second display unit 103 in accordance with the combination of the imaging posture and the rotation state. Further, “default control” refers to control performed according to a predetermined priority regardless of the combination of the imaging posture and the rotation state. Note that if the priority determination between “state priority control” and “default control” conflicts, the system control unit 150 performs “state priority control” with priority over “default control”.

  Next, referring to FIG. 5, when the imaging posture is “posture 2” or “posture 3” and the rotation state is “transition position”, the user is positioned on the back side of the photographing lens. There is a high possibility that the display unit 102 is directly facing. In this case, it is difficult for the user to check the second display unit 103. Therefore, the system control unit 150 performs “state priority control” in which an image is displayed on the first display unit 102 (priority display) and the second display unit 103 is turned off. Note that “posture 2” and “posture 3” are states in which the axis C1 is substantially at the same position as the first display unit 102 in the direction of gravity.

  When the imaging posture is “posture 4” and the rotation state is “transition position”, the user raises the camera 100 upward and confirms the image by the second display unit 103, so-called high-angle shooting posture. Is likely.

  In this case, it becomes difficult for the user to check the first display unit 102. Therefore, the system control unit 150 performs “state priority control” in which an image is displayed on the second display unit 103 and the first display unit 102 is turned off.

  “Position 4” is a state in which the axis C1 is at a position above the first display unit 102 in the direction of gravity. “Position 1” is a state in which the axis C1 is at a position below the first display unit 102 in the direction of gravity.

  On the other hand, as shown in FIG. 4, in a state where it is difficult to determine the priority based on the combination of the imaging posture and the rotation state, the system control unit 150 is based on a predetermined priority (default setting). Perform “default control”. That is, here, the system control unit 150 displays an image on a display unit with high priority based on the default setting, and turns off the other display unit.

  The default setting may be set according to, for example, the resolution of the display unit, and may be set according to the presence or absence of an additional function such as a touch panel function. In addition, the default setting may be to preferentially set a display unit having an image aspect ratio and a similar aspect ratio, and a display unit (here, the first display unit) having a short distance from the optical axis in consideration of parallax. The display unit 102) may be set with priority.

  Further, as shown in FIG. 5, in the combination of the imaging posture and the rotation state as “default control”, it is sometimes easy to confirm an image even on a display unit with low priority. For this reason, auxiliary display that improves operability such as display of settings of the camera 100 may be performed on the display unit with high priority without turning off the display unit with low priority.

  FIG. 6 is a flowchart for explaining an example of display control of the display unit performed by the camera 100 shown in FIG. The display control shown in FIG. 6 is performed by developing a program recorded in the nonvolatile memory 151 in the volatile memory (work memory) 152 and executing it by the system control circuit 150.

  When the display control is started, the system control unit 150 detects the position of the hinge mechanism (that is, the rotation angle θc1) by the open / close detection sensor 110 in step S601, and the hinge mechanism (that is, the first display unit 102) If the position of the hinge mechanism is the transition position, the process proceeds to step S601, and if the position of the hinge mechanism is the fully closed position, the process proceeds to step S602. If there is, the process proceeds to S604.

  In step S <b> 601, the system control unit 150 detects the posture of the camera 100 by the posture detection sensor 111 and determines the imaging posture of the camera 100. When the imaging posture of the camera 100 is the posture 1, the process proceeds to S605, and when the imaging posture of the camera 100 is the posture 2 or the posture 3, the process proceeds to S606. If the imaging posture of the camera 100 is posture 4, the process proceeds to S607.

  In step S <b> 603, the system control unit 150 performs all extinguishing to turn off the first display unit 102 and the second display unit 103. Then, the system control unit 150 ends the display control.

  In S604, the system control unit 150 performs default control according to the default setting. Then, the system control unit 150 ends the display control.

  In step S605, the system control unit 150 performs default control according to the default setting. Then, the system control unit 150 ends the display control.

  In step S <b> 606, the system control unit 150 performs state priority control that prioritizes the first display unit 102. Then, the system control unit 150 ends the display control.

  In step S <b> 607, the system control unit 150 performs state priority control that prioritizes the second display unit 103. Then, the system control unit 150 ends the display control.

  As described above, in the first embodiment of the present invention, the first display unit 102 and the second display unit 103 are turned off and off according to the rotation position of the first display unit 102 and the posture of the camera 100. Control priority display. Thereby, power consumption can be reduced without impairing user convenience.

[Second Embodiment]
FIG. 7 is a perspective view showing an appearance of an example of an imaging apparatus according to the second embodiment of the present invention. FIG. 7A is a perspective view of the imaging device as seen from the back side, and FIG. 7B is a perspective view of the imaging device as seen from the front side with the photographing lens removed.

  Here, the subject side is defined as the front side in the optical axis direction of the photographing lens described later. The vertical and horizontal directions are based on a user located on the back side (rear side) of the imaging apparatus. Further, in FIG. 7, the same reference numerals are assigned to the same components as those of the camera shown in FIG. In the second embodiment, the first display unit 102 corresponds to the second display unit, and the second display unit 103 corresponds to the first display unit.

  An illustrated imaging apparatus (hereinafter referred to as a camera) 200 is a so-called digital single-lens reflex camera, and a photographing lens 104 is attached to a lens mount 250. The first display unit 102 is disposed on the opposite side of the lens mount 250, that is, on the back side of the camera body 101, and the camera body 101 is provided with a hinge mechanism 205 having two axes orthogonal to each other. The second display unit 103 is rotatably attached to the camera body 101 by 205.

  The second display unit 103 is rotatable (openable and closable) from a predetermined “fully closed position” to a “fully open position” about the axis C1 (first axis) by a hinge mechanism 205. Here, the “fully closed position” refers to a position where the second display unit 103 approaches or abuts against the first display unit 102. The “fully opened position” refers to a position where the second display unit 103 is rotated 180 degrees in the opening direction from the “fully closed position”. That is, the second display unit 103 can be rotated 180 degrees from the “fully closed position”. The rotation angle from the “fully closed position” (that is, the open / close position) is θc1. Further, in the example illustrated in FIG. 7, a state in which the second display unit is located at the “fully open position” is illustrated.

  Furthermore, the second display unit 103 is rotated from -90 degrees to 180 degrees with the hinge mechanism 205 centered on the axis C2 (second axis) and the state shown in FIG. It can be rotated up to a degree. Then, from the state shown in FIG. 7A, the rotation direction in which the display surface of the second display unit 103 is directed to the upper surface side is defined as a plus direction, and the rotation direction directed to the lower surface side is defined as a minus direction. Further, the rotation angle around the axis C2 from the state shown in FIG.

  FIG. 8 is a block diagram showing a system configuration of the camera shown in FIG. In FIG. 8, the same components as those in the camera shown in FIG.

  The illustrated camera 200 includes a rotation detection sensor 112, and the rotation detection sensor 112 is connected to the tostem control unit 150. Similar to the open / close detection sensor 110, the rotation detection sensor 112 is disposed in or near the hinge mechanism 205 and detects the rotation angle θc2 of the second display unit 103. The rotation detection sensor 112 includes a single or a plurality of contact type switches. The rotation detection sensor 112 may be a non-contact detection unit using a hall element, a photo interrupter, or the like.

  In the illustrated example, the system control unit 150 determines the rotation state (that is, the rotation position) around the axis C2 in the second display unit 103 based on the output (detection result) of the rotation detection sensor 112. For example, the system control unit 150 determines the fourth and fifth rotation states as the rotation state around the axis C <b> 2 of the second display unit 102.

  The fourth rotation state is a state where the rotation angle θc2 is −15 degrees or more and less than 15 degrees. That is, the fourth rotation state is a state in which the second display unit 103 is located in a predetermined rotation range. The fifth rotation state refers to a state in which the rotation angle θc2 is any other angle, that is, −90 degrees or more and less than −15 degrees or 15 degrees or more and 180 degrees or less.

  Here, based on the output of the open / close detection sensor 110, the system control unit 150 determines whether the second display unit 103 is in the first to third rotation states described above.

  FIG. 9 is a diagram for explaining an imaging posture (camera posture) when imaging is performed using the camera 200 illustrated in FIG. 8. FIG. 9A is a diagram illustrating an example of the imaging posture, and FIG. 9B is a diagram illustrating another example of the imaging posture. FIG. 9C is a diagram showing still another example of the imaging posture.

  In the imaging posture shown in FIG. 9A, the grip portion 251 (see FIG. 7) of the camera 200 is held with the right hand, and the photographing lens attached to the lens mount 250 is held with the left hand. That is, the user holds the camera 200 in a so-called normal position, and takes an image while taking an eye on the optical viewfinder 252 (see FIG. 7). In the second embodiment, the imaging posture is referred to as “posture 1”.

  In the imaging posture shown in FIG. 9B, the grip unit 251 is held with the right hand and the photographing lens is held with the left hand, the camera 200 is held in a vertical position with the grip unit 251 side down, and the user is in the optical viewfinder 252. Have an eye. In the second embodiment, the imaging posture is referred to as “posture 2”.

  In the imaging posture shown in FIG. 9C, the grip unit 251 is held with the right hand and the photographing lens is held with the left hand, and the camera 200 is held in a vertical position with the grip unit 251 side on the upper side. I have an eye. In the second embodiment, the imaging posture is referred to as “posture 3”.

  By the way, in general, in a digital single lens reflex camera, the grip unit 251 is gripped with the right hand, and shooting is performed with the right hand index finger placed on the shooting switch 253 (see FIG. 7). For this reason, unlike the “posture 4” described in the first embodiment, the user is unlikely to take an imaging posture in which the right hand and the left hand are interchanged. Therefore, in the second embodiment, “posture 4” is not considered.

  FIG. 10 is a diagram illustrating an example of control according to the combination of the rotation state of the second display unit illustrated in FIG. 7 and the imaging posture. FIG. 11 shows the state of the camera 200 according to the combination of the imaging posture and the fully closed position, the transition position, and the fully open position when the second display unit shown in FIG. 7 is in the fourth rotation state. FIG. Further, FIG. 12 shows the state of the camera 200 according to the combination of the imaging posture and the fully closed position, the transition position, and the fully open position when the second display unit shown in FIG. 7 is in the fifth rotation state. FIG.

  11 and 12, a state where the angle θc1 is 0 degrees is shown as an example of the “fully closed position”, and a state where the angle θc1 is 90 degrees is shown as an example of the “transition position”. Further, as an example of the “fully open position”, a state where the angle θc1 is 180 degrees is shown. Further, FIG. 11 shows a state where the angle θc2 is 0 degree as an example of the fourth rotation state, and FIG. 12 shows a state where the angle θc2 is 180 degrees as an example of the fifth rotation state.

  First, referring to FIG. 10, “all off” means a state in which both the first display unit 102 and the second display unit 103 are turned off. “State priority control” is control for giving priority to the first display unit 102 or the second display unit 103 in accordance with the combination of the imaging posture and the rotation state. Further, “default control” refers to control performed according to a predetermined priority regardless of the combination of the imaging posture and the rotation state. Note that if the priority determination between “state priority control” and “default control” conflicts, the system control unit 150 performs “state priority control” with priority over “default control”.

  Next, referring to FIG. 11, when the angle θc1 is “fully closed position”, it is almost impossible for the user to check the first display unit 102 and the second display unit 103 regardless of the imaging posture. Since it is impossible, the system control unit 150 controls “all off”.

  When the imaging posture is “posture 1” and the angle θc1 is “transition position”, there is a high possibility that the user holds the first display unit 102 directly. For this reason, it becomes difficult for the user to check the second display unit 103. Therefore, the system control unit 150 performs “state priority control” that preferentially displays an image on the first display unit 102 and turns off the second display unit 103.

  In the second embodiment, “posture 1” is a state in which the axis C1 is substantially in the same position as the first display unit 102 (second display means in the second embodiment) in the direction of gravity. is there.

  When the imaging posture is “posture 2” and the angle θc1 is “transition position”, the user can raise the camera 200 upward and check the image on the second display unit 103, which is a so-called high-angle shooting posture. High nature. For this reason, it becomes difficult for the user to check the first display unit 102. Therefore, the system control unit 150 performs “state priority control” that preferentially displays an image on the second display unit 103 and turns off the first display unit 102.

  In the second embodiment, “posture 2” is a state in which the axis C1 is in a position above the first display unit 102 (second display means in the second embodiment) in the direction of gravity. is there.

  When the imaging posture is “posture 3” and the angle θc1 is “transition position”, the user holds the camera 200 on the lower side and confirms an image on the second display unit 103 in a so-called low-angle shooting posture. There is a high possibility. For this reason, it becomes difficult for the user to check the first display unit 102. Therefore, the system control unit 150 performs “state priority control” that preferentially displays an image on the second display unit 103 and turns off the first display unit 102.

  In the second embodiment, “posture 3” is a state in which the axis C1 is in a position below the first display unit 102 (second display means in the second embodiment) in the direction of gravity. It is.

  When the angle θc1 is the “fully open position”, it is difficult to determine the priority of the display unit depending on the combination of the imaging posture and the rotation state. Therefore, the system control unit 150 performs “default control” according to the default setting. That is, the system control unit 150 displays an image on a display unit with high priority according to the default setting, and puts the other display unit in the off state.

  When the angle θc1 is “fully open position”, the user may be able to easily check the display unit with a low priority. Therefore, the system control unit 150 may perform auxiliary display for improving operability such as setting display of the camera 200 on the display unit without turning off the display unit with low priority.

  Next, referring to FIG. 12, when the angle θc1 is “fully closed position”, the user can hardly check the first display unit 102 regardless of the imaging posture. Therefore, the system control unit 150 performs “state priority control” in which the image is preferentially displayed on the second display unit 103 and the first display unit 102 is turned off.

  When the angle θc1 is the “transition position” or the “full open position”, when the second display unit 103 is rotated to a position other than the angle θc2 of −15 or more and less than 15 degrees, the second display unit 103 of the camera 200 is moved. It becomes difficult to check from the back side. When such a rotation is performed, it is considered that the user intends to allow the second display unit 103 to be observed by persons other than the back side of the camera 200 (including the user himself / herself). Specifically, it is considered that the above-described rotation is performed in so-called self-shooting, high-angle shooting, low-angle shooting, or shooting in a special posture in which shooting is performed with the shooting lens facing the user. In addition, it is considered that the above rotation is performed also when an image obtained by photographing is reproduced and presented to a subject or the like.

  A point common to the above case is a situation where the second display unit 103 is preferentially observed. Considering this point, the system control unit 150 performs “state priority control” that preferentially displays an image on the second display unit 103 and turns off the first display unit 102.

  FIG. 13 is a flowchart for explaining an example of display control of the display unit performed by the camera 200 shown in FIG.

  The display control shown in FIG. 13 is performed by developing a program recorded in the nonvolatile memory 151 in the volatile memory 152 and executing it by the system control circuit 150. In FIG. 13, the same steps as those in the flowchart shown in FIG. 6 are denoted by the same reference numerals, and the description thereof is omitted.

  When display control is started, in S1301, the system control unit 150 detects the rotation angle θc2 of the hinge mechanism by the rotation detection sensor 112, and the second display unit 103 is in any of the fourth and fifth states. Determine whether. When the second display unit 103 is in the fourth state (when θc2 = −15 to 15 degrees), the process proceeds to step S601 described above. When the second display unit 103 is in the fifth state (when θc2 = −90 to −15 degrees or 15 to 180 degrees), the process proceeds to step S1302. In the second embodiment, it is determined in S601 whether the second display unit 103 is in the fully closed position, the transition position, or the fully opened position.

  In step S1302, the system control unit 150 performs state priority control that prioritizes the second display unit 103. Then, the system control unit 150 ends the display control.

  When the 2nd display part 103 is a transition position, it progresses to S602. When the 2nd display part 103 is a fully closed position, it progresses to S603. Thereafter, the system control unit 150 ends the display control. If the second display unit 103 is in the fully open position, the process proceeds to S604. Thereafter, the system control unit 150 ends the display control.

  If the imaging posture of the camera 200 is posture 1, the process proceeds to S1303. If the imaging posture of the camera 200 is posture 2 or 3, the flow proceeds to S1304.

  In step S <b> 1303, the system control unit 150 performs state priority control that prioritizes the first display unit 102. Then, the system control unit 150 ends the display control.

  In step S <b> 1304, the system control unit 150 performs state priority control that prioritizes the second display unit 103. Then, the system control unit 150 ends the display control.

  As described above, in the second embodiment of the present invention, the first display unit 102 and the second display unit 102 are controlled according to the rotation position of the second display unit 102 around the axes C1 and C2 and the attitude of the camera 200. The display unit 103 is turned off and priority display is controlled. Thereby, power consumption can be reduced without impairing user convenience.
