  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of an electronic camera 100 according to the first embodiment. As shown in FIG. 1, an electronic camera 100 includes an imaging optical system 1, a light amount adjustment unit 2, an imaging device 3, an A / D conversion unit 4, a CPU 5, a card memory 6, a built-in memory 7, an operation unit 8, and a position detection sensor. 9, a display unit 10, a focus lens driving unit 14, a zoom lens driving unit 15, and a light amount adjustment control unit 16. The CPU 5, the built-in memory 7, the operation unit 8, the position detection sensor 9, and the display unit 10 are connected via a bus 17 and can exchange information with each other.

  The imaging optical system 1 includes a plurality of optical lenses including a focus lens 12 and a zoom lens 13, and forms a subject image on the light receiving surface of the imaging element 3. The focus lens 12 and the zoom lens 13 are provided to be movable along the optical axis L1, and their positions are adjusted by a focusing operation by the focus lens driving unit 14 and a zooming operation by the zoom lens driving unit 15. . Note that the focus lens driving unit 14 and the zoom lens driving unit 15 are connected to the CPU 5, and control the position adjustment of the focus lens 12 and the zoom lens 13 according to a command from the CPU 5.

  The light amount adjustment unit 2 includes an aperture mechanism and a shutter mechanism, and captures a light flux from the subject (optical axis L1) for a time determined by the shutter speed (exposure time) in order to capture the subject image with the imaging device 3. The light is passed through the light receiving surface of the element 3. The diaphragm operation and shutter operation of the light amount adjusting unit 2 are controlled by the light amount adjusting control unit 16 based on a command from the CPU 5.

  An imaging element 3 that receives a light beam from the subject is provided on the planned focal plane of the photographing optical system on the optical axis L1. The image sensor 3 is composed of a device such as a CCD image sensor, a CMOS sensor, or a CID. The imaging device 3 generates and outputs analog image data corresponding to the subject image formed on the pixels of the imaging device 3 by the imaging optical system 1. Analog image data output from the image sensor 3 is converted into digital image data by the A / D converter 4 and transferred to the CPU 5. Here, the A / D conversion unit 4 may be built in the image sensor 3. When the A / D converter 4 is built in the image sensor 3, the image sensor 3 outputs digital image data.

  The CPU 5 performs image processing on the input digital image data. The image processing is, for example, gradation conversion processing or white balance processing. The CPU 5 also controls the entire electronic camera 100 such as detection of a focus adjustment state and an aperture adjustment state.

  A card memory 6 is detachably attached to a card I / F (not shown) of the electronic camera 100. The image data generated by the CPU 5 is stored in the card memory 6 via the card I / F.

  The built-in memory 7 stores a control program for the CPU 5 to control the electronic camera 100. The control program stored in the built-in memory 7 is referred to from the CPU 5 through the bus 17 as appropriate. As the built-in memory 7, any non-volatile memory among semiconductor memories can be appropriately selected and used.

  The operation unit 8 is a shutter release button, an input switch for setting various operation modes of the electronic camera 100, and the like, and can switch between an autofocus mode and a manual focus mode, for example. In the present embodiment, the operation unit 8 also includes a zoom button for driving the zoom lens 13 to change the shooting magnification. Various modes set by the operation unit 8 are sent to the CPU 5, and the operation of the entire electronic camera 100 is controlled by the CPU 5. The shutter release button includes a first switch SW1 that is turned on when the button is half-pressed and a second switch SW2 that is turned on when the button is fully pressed.

  The display unit 10 includes a display monitor 101. The display unit 10 displays an image indicated by the image data generated by the image sensor 3 on the display monitor 101. For example, a live view image or a captured image is displayed on the display monitor 101. 2A and 2B are external views of the electronic camera 100 according to this embodiment, and FIG. 2A shows a state in which the display unit 10 is accommodated along the camera body 20. FIG. 2B shows a state in which the display unit 10 is pulled out from the camera body 20. The display unit 10 according to the present embodiment is a vari-angle liquid crystal monitor (tilt angle liquid crystal monitor), and has a display monitor 101 and rotating shafts 102a and 102b as shown in FIGS. doing. Then, as shown in FIG. 2A, the display monitor 101 is rotated in the yaw direction D1 with respect to the optical axis about the rotation axis 102a in the state where the display unit 10 is accommodated along the camera body 20. After that, the display monitor 101 is further rotated about the rotation axis 102b in the pitch direction D2 with respect to the optical axis, whereby the display unit 10 is pulled out from the camera body 20 as shown in FIG. State.

  FIG. 3A shows a scene where the photographer performs high-angle shooting in which the electronic camera 100 is raised above the photographer's line of sight. When performing high-angle shooting, in order to check whether or not the subject is within the shooting range, the photographer moves the display monitor 101 of the display unit 10 downward as shown in FIG. 3B. The action of turning is performed.

  FIG. 4A shows a scene where the photographer performs low-angle shooting in which the electronic camera 100 is lowered below the photographer's line of sight. Even when performing low-angle shooting, in order to confirm whether or not the subject is within the shooting range, the photographer moves the display monitor 101 of the display unit 10 upward as shown in FIG. The action of turning is performed.

  Here, scenes where high-angle shooting is performed, for example, when shooting a child from a place far away from the photographer in an athletic meet, the photographer avoids obstacles ahead and exists relatively far away. There are many scenes to shoot. In such a case, as shown in FIG. 3A, the photographer holds the electronic camera 100 apart from the photographer's body, so that the photographer's posture becomes unstable and the display monitor 101 is held. In addition to the downward operation, the zoom button of the operation unit 8 is further operated to enlarge the subject image. With these operations, the shooting direction of the electronic camera 100 is directed in a direction contrary to the photographer's intention. The subject may be out of the shooting range.

  In addition, when performing low-angle shooting, for example, when a photographer photographs a subject that is relatively close, for example, when shooting a flower that exists nearby. Even in such a case, as shown in FIG. 4A, the photographer holds the electronic camera 100 away from the photographer's body, and thus the photographer's posture becomes unstable and the display monitor 101 In order to reduce the subject image, the zoom button of the operation unit 8 is further operated in order to reduce the subject image, so that these operations cause the shooting direction of the electronic camera 100 to be in a direction contrary to the photographer's intention. In some cases, the subject is out of the shooting range.

  Therefore, in the present embodiment, the CPU 5 controls the driving of the zoom lens 13 based on the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3. Specifically, the CPU 5 rotates the display monitor 101 in the pitch direction D2 about the rotation axis 102b, so that the high-angle shooting is performed when the display monitor 101 of the display unit 10 is directed downward. The zoom lens 13 is driven to the tele side so that the photographing magnification is increased. More specifically, the CPU 5 determines the angle θ in the pitch direction D2 formed by the optical axis of the camera body 20 and the normal line of the display monitor 101 when the display monitor 101 of the display unit 10 is directed downward in the vertical direction. The zoom lens 13 is driven to the tele side so that the photographing magnification increases as the (the pitch angle θ between the optical axis and the normal line of the display monitor 101) increases.

  For example, as shown in FIG. 5 (A), the CPU 5 does not change the pitch angle θ between the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 to 45 ° in FIG. 5 (B). As shown in the figure, the zoom lens 13 is driven to the tele side so that the shooting magnification is larger when the pitch angle θ between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 is 90 °. Let Accordingly, since the operation of the zoom button for enlarging the subject image can be omitted in the high angle shooting, the photographer further performs the zoom button operation in the high angle shooting where the posture of the photographer is likely to be unstable. Thus, it is possible to effectively prevent the photographing direction of the electronic camera 100 from being in a direction contrary to the photographer's intention and the subject from being out of the photographing range.

  On the other hand, the CPU 5 rotates the display monitor 101 in the pitch direction D2 about the rotation axis 102b, so that when the display monitor 101 of the display unit 10 is directed upward, low-angle shooting is performed. And the zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. More specifically, when the display monitor 101 of the display unit 10 is directed vertically upward, the CPU 5 increases the pitch angle θ between the optical axis of the camera body 20 and the normal line of the display monitor 101 as The zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. Accordingly, since the operation of the zoom button for reducing the subject image can be omitted in the low-angle shooting, the photographer further performs the zoom button operation in the low-angle shooting in which the posture of the photographer is likely to be unstable. Thus, it is possible to effectively prevent the photographing direction of the electronic camera 100 from being in a direction contrary to the photographer's intention and the subject from being out of the photographing range.

  The relative position of the display monitor 101 with respect to the image sensor 3 is detected by the position detection sensor 9. For example, in this embodiment, the position detection sensor 9 is provided in the vicinity of the rotation shafts 102a and 102b of the display unit 10, and the rotation angle of the display unit 10 around the rotation shafts 102a and 102b is detected by the position detection sensor 9. Thus, the pitch angle θ between the optical axis and the normal line of the display monitor 101, and the yaw angle in the yaw direction D1 formed by the optical axis of the camera body 20 and the normal line of the display monitor 101 are displayed on the display monitor. 101 is detected as a relative position.

  Further, the position detection sensor 9 may be constituted by a GPS unit or a gyro sensor, and may be configured to detect the height position of the electronic camera 100 (or the image sensor 3). In this case, in addition to the display monitor 101 being directed downward, when the electronic camera 100 is positioned higher than the photographer's line of sight, it is determined that high-angle shooting is performed, and the shooting magnification is increased. The zoom lens 13 can be driven to the telephoto side. Similarly, in addition to the display monitor 101 being directed upward, when the electronic camera 100 is positioned lower than the photographer's line of sight, it is determined as low angle shooting so that the shooting magnification is reduced. The zoom lens 13 can be driven to the wide side.

  Furthermore, when the display monitor 101 is directed downward in the vertical direction, the CPU 5 does not immediately drive the zoom lens 13 to the telephoto side, but after a certain time has elapsed after the display monitor 101 is directed downward in the vertical direction. In this case, the zoom lens 13 may be driven to the tele side. Thus, since the shooting range is wide immediately after the display monitor 101 is directed downward in the vertical direction, it is possible to appropriately fit the subject within the shooting range even in an unstable state immediately after the display monitor 101 is directed downward. Become.

  Further, the drive control of the zoom lens 13 may be continuously performed in accordance with the change in the relative position of the display monitor 101 with respect to the image pickup device 3 or the change in the relative position of the display monitor 101 with respect to the image pickup device 3. It is good also as a structure performed intermittently according to it. For example, the zoom lens 13 is continuously driven by driving the zoom lens 13 every time the pitch angle between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 changes by 0.1 degree. Alternatively, each time the pitch angle between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 changes by 5 degrees, the zoom lens 13 is driven, so that the zoom lens 13 is intermittently operated. It is good also as a structure to drive.

  Next, an operation example of the electronic camera 100 according to the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the electronic camera 100 according to the first embodiment.

  First, in step S <b> 101, the CPU 5 acquires the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3. In the present embodiment, as shown in FIGS. 5A and 5B, the CPU 5 detects the pitch angle between the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 detected by the position detection sensor 9. θ is acquired from the position detection sensor 9 as the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3.

  In step S102, the CPU 5 determines whether or not the display monitor 101 is directed downward in the vertical direction based on the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3 acquired in step S101. Is called. If it is determined that the display monitor 101 is directed downward in the vertical direction, the process proceeds to step S103, and the CPU 5 performs a process of driving the zoom lens 13 to the tele side so that the photographing magnification is increased. . In this case, the CPU 5 drives the zoom lens 13 to the telephoto side so that the photographing magnification increases as the pitch angle θ between the optical axis and the normal line of the display monitor 101 increases.

  On the other hand, if it is determined in step S102 that the display monitor 101 is not directed downward in the vertical direction, the process proceeds to step S104. In step S104, the CPU 5 determines whether or not the display monitor 101 is directed upward in the vertical direction based on the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the imaging device 3 acquired in step S101. Is called. If it is determined that the display monitor 101 is directed upward in the vertical direction, the process proceeds to step S105, and the CPU 5 performs a process of driving the zoom lens 13 to the wide side so that the photographing magnification is reduced. . In this case, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification decreases as the pitch angle θ between the optical axis and the normal line of the display monitor 101 increases.

  Then, after the focus lens 32 is driven in step S103 or step S105, the process returns to step S101. Thereby, whenever the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3 changes (every time the display monitor 101 is rotated upward or downward), the zoom lens 13 is changed based on the relative position. It will be driven repeatedly.

  As described above, the operation of the electronic camera 100 according to the first embodiment is performed.

  As described above, in the first embodiment, when the display monitor 101 is directed downward, it is determined that high-angle shooting is performed, and as the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101 increases. The zoom lens 13 is driven to the tele side so that the photographing magnification is increased. Further, when the display monitor 101 of the display unit 10 is directed upward, it is determined that low-angle shooting is performed, and the larger the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101, the higher the shooting magnification. The zoom lens 13 is driven to the wide side so as to decrease. As a result, in high-angle shooting or low-angle shooting where the photographer's posture is likely to be unstable, the zoom button operation can be omitted and the zooming operation can be performed. It is possible to effectively prevent the camera from being out of the shooting range.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described. The electronic camera 100 according to the second embodiment has the same configuration as the electronic camera 100 according to the first embodiment, and is the same as the electronic camera 100 according to the first embodiment except that it operates as described below. To work.

  In the second embodiment, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification decreases when the display monitor 101 of the display unit 10 is directed upward or downward. That is, in the first embodiment described above, when the display monitor 101 of the display unit 10 is directed downward, the zoom lens 13 is driven to the tele side so as to increase the photographing magnification, while the display unit 10 When the display monitor 101 is directed upward, the zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. However, in the second embodiment, the display monitor 101 of the display unit 10 is directed upward. The zoom lens 13 is driven to the wide side so that the photographing magnification is reduced both when it is directed and when it is directed downward.

  In the second embodiment, the CPU 5 drives to the wide side when a certain time has elapsed after driving the zoom lens 13 to the wide side according to the relative position of the display monitor 101 with respect to the image sensor 3. The lens position of the zoom lens 13 is gradually returned to the original lens position before driving. For example, when the imaging magnification increases as the focal length of the imaging optical system 1 increases, the CPU 5, as shown in FIG. 5A, when the display monitor 101 of the display unit 10 is directed downward, The lens before driving the zoom lens 13 so that the focal length returns from 600 mm to 800 mm when the zoom lens 13 is driven to the wide side so that the focal length changes from 800 mm to 600 mm and then a certain time has passed. Drive gradually to the position. Similarly, even when the display monitor 101 of the display unit 10 is directed upward, the CPU 5 moves the lens position of the zoom lens 13 driven to the wide side to the original position before driving after a predetermined time has elapsed. Return gradually.

  Thus, in the second embodiment, when the photographer performs high-angle shooting or low-angle shooting, first, the zoom lens 13 is driven to the wide side so that the shooting magnification is reduced. Can be easily accommodated. Then, when a certain period of time has elapsed after the zoom lens 13 is driven to the wide side, the photographer can gradually return the zoom lens 13 to the lens position before driving, so that the photographer does not operate the zoom button. While confirming the subject on the display monitor 101, it is possible to fit the subject within a photographing range with a desired size.

  Furthermore, in the second embodiment, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification decreases as the pitch angle θ between the optical axis of the camera body 20 and the normal line of the display monitor 101 increases. . For example, when the imaging magnification increases as the focal length of the imaging optical system 1 increases, the CPU 5 determines that the optical axis L1 of the camera body 20 is as shown in FIG. And the normal L2 of the display monitor 101 is 45 degrees, the zoom lens 13 is driven to the wide side so that the focal length is 800 mm to 600 mm. On the other hand, when the focal length is also 800 mm, the CPU 5 has a pitch angle θ formed by the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 as shown in FIG. When the angle is 90 degrees, the zoom lens 13 is driven to the wide side so that the focal length is 800 mm to 400 mm. Similarly, when the display monitor 101 of the display unit 10 is directed upward, the CPU 5 decreases the imaging magnification as the pitch angle θ between the optical axis of the imaging optical system 1 and the normal line of the display monitor 101 increases. Thus, the zoom lens 13 is driven to the wide side.

  In addition, in the second embodiment, the CPU 5 drives the zoom lens 13 in consideration of the photographing magnification before changing the relative position of the display monitor 101 with respect to the image sensor 3. Specifically, the CPU 5 drives the zoom lens 13 so that the amount of change in the photographing magnification before and after the rotation of the display monitor 101 does not increase as the photographing magnification before rotating the display monitor 101 increases. For example, when the imaging magnification increases as the focal length of the imaging optical system 1 increases, the CPU 5 increases the focal length change before and after the rotation of the display monitor 101 as the focal length before the display monitor 101 rotates. The driving of the zoom lens 13 is controlled so that is not large.

  For example, when the focal length before rotating the display monitor 101 is 800 mm, the CPU 5 has a pitch between the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 as shown in FIG. When the angle θ is 45 degrees, the zoom lens 13 is driven to the wide side so that the focal length is 800 mm to 600 mm. On the other hand, when the focal length before rotating the display monitor 101 is 500 mm, the CPU 5 similarly shows the optical axis L1 of the camera body 20 and the normal line of the display monitor 101 as shown in FIG. When the pitch angle θ with L2 is 45 degrees, the zoom lens 13 is driven to the wide side so that the focal length is 500 mm to 400 mm. That is, when the focal length before rotating the display monitor 101 is 800 mm, the CPU 5 drives the zoom lens 13 so that the focal length changes by 300 mm, while the focal point before rotating the display monitor 101. When the distance is 500 mm, the zoom lens 13 is driven so that the focal length changes by 100 mm. Similarly, when the display monitor 101 of the display unit 10 is directed upward, the CPU 5 increases the amount of change in the shooting magnification before and after the rotation of the display monitor 101 as the shooting magnification before the display monitor 101 is rotated is larger. The zoom lens 13 is driven so as not to exist.

  Further, the CPU 5 zooms so that the amount of change in the photographing magnification before and after the rotation of the display monitor 101 becomes larger when the display monitor 101 is directed downward than when the display monitor 101 is directed upward. The lens 13 is driven to the wide side. For example, when the imaging magnification increases as the focal length of the imaging optical system 1 increases, the CPU 5 turns the display monitor 101 downward as shown in FIG. 5A when the focal length is 800 mm. When the pitch angle θ between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 is 45 degrees, the zoom lens 13 is moved to the wide side so that the focal length is 800 mm to 600 mm. To drive. On the other hand, when the focal length is 800 mm, the CPU 5 has the display monitor 101 directed upward, and the pitch angle θ between the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 is 45 degrees. In this case, the zoom lens 13 is driven to the wide side so that the focal length is 800 mm to 700 mm.

  Next, an operation example of the electronic camera 100 according to the second embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the electronic camera 100 according to the second embodiment.

  First, in step S201, the CPU 5 detects the photographing magnification. For example, the CPU 5 can calculate the photographing magnification by dividing the focal length value of the imaging optical system 1 by the subject distance value. Note that the photographing magnification detected in step S201 is detected as the photographing magnification before the rotation operation of the display monitor 101.

  Next, in step S202, the CPU 5 determines whether or not the display monitor 101 has been rotated. If the photographer rotates the display monitor 101, the process proceeds to step S203. On the other hand, if the photographer does not rotate the display monitor 101, the process returns to step S201, and the shooting magnification is set. Detection is repeated.

  In step S <b> 203, the CPU 5 detects the relative position of the display monitor 101 with respect to the image sensor 3. Specifically, the CPU 5 displays the pitch angle θ between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 as shown in FIGS. 101 is detected as a relative position. In step S204, the CPU 5 detects the rotation direction of the display monitor 101.

  In step S205, the CPU 5 calculates the driving amount of the zoom lens 13 based on the detection results in steps S201, S203, and S204. Specifically, the CPU 5 detects the photographing magnification before the rotation operation of the display monitor 101 detected in step S201, and the current pitch angle between the optical axis of the camera body 20 detected in step S203 and the normal line of the display monitor 101. Based on the rotation direction of the display monitor 101 detected in step S204, the target shooting magnification is determined, and the driving amount of the zoom lens 13 is calculated so that the target shooting magnification is obtained.

  For example, as shown in FIGS. 5A and 5B, the CPU 5 increases the photographing magnification as the pitch angle θ between the optical axis L1 of the camera body 20 and the normal L2 of the display monitor 101 increases. Then, the driving amount of the zoom lens 13 is calculated. Further, the CPU 5 calculates the driving amount of the zoom lens 13 so that the amount of change in the photographing magnification before and after the rotation of the display monitor 101 increases as the photographing magnification before the rotation operation of the display monitor 101 increases. Further, the CPU 5 calculates the driving amount of the zoom lens 13 so that the change amount of the photographing magnification becomes larger when the display monitor 101 is directed downward than when the display monitor 101 is directed upward.

  In step S206, the CPU 5 drives the zoom lens 13 based on the driving amount of the zoom lens 13 calculated in step S205. In the second embodiment, the driving amount of the zoom lens 13 is calculated so as to reduce the photographing magnification, regardless of whether the display monitor 101 is directed upward or vertically downward. In step S206, the zoom lens 13 is driven to the wide side.

  In step S207, the CPU 5 determines whether or not a predetermined time has elapsed after the zoom lens 13 is driven. If it is determined that the fixed time has elapsed, the process proceeds to step S208. On the other hand, if it is determined that the fixed time has not elapsed, the process waits in step S207 until the fixed time has elapsed.

  In step S208, since it is determined that a fixed time has elapsed since the zoom lens 13 was driven, the CPU 5 returns the lens position of the zoom lens 13 to the original lens position before the display monitor 101 is rotated. Processing is performed. Specifically, the CPU 5 drives the zoom lens 13 to the tele side to the original lens position before the display monitor 101 is rotated so that the photographing magnification before the rotation operation of the display monitor 101 is obtained.

  Thus, the operation of the electronic camera 100 according to the second embodiment is performed.

  Next, the operation of the electronic camera 100 according to the second embodiment will be described with reference to FIGS. 8A to 8C. 8A to 8C are diagrams for explaining the operation of the electronic camera 100 according to the second embodiment. In FIGS. 8A to 8C, (A) to (E) show the driving state of the zoom lens on the left side of the drawing. The larger the lens barrel of the electronic camera 100 extends to the subject side, the larger the photographing magnification. As shown, the zooming operation is performed. Also, an example of an image displayed on the display monitor 101 is shown on the right side of the figure.

  Further, the scenes shown in FIGS. 8A to 8C are scenes where the photographer is photographing the subject as shown in FIG. 8A (A), and as shown in FIG. In order to take an enlarged image, the zoom button 13 is operated to drive the zoom lens 13 to the telephoto side. Then, as a result of the photographer operating the zoom button to enlarge the subject, the obstacle appears in front of the subject. Therefore, as shown in FIG. 8B (C), the electronic camera 100 is viewed from the photographer's line of sight. Also lifted up.

  In this manner, when the electronic camera 100 is raised above the photographer's line of sight while the subject is magnified (with a large photographing magnification), the electronic camera 100 is held away from the photographer's body. For this reason, due to camera shake or the like, the shooting direction of the electronic camera 100 may become a direction unintended by the photographer, and the subject may be out of the shooting range. For example, in the example shown in FIG. 8B (C), the subject is out of the shooting range because the electronic camera 100 is raised above the photographer's line of sight while the subject is enlarged (when the shooting magnification is large). I'm stuck.

  On the other hand, in the present embodiment, as shown in FIG. 8B (D), the photographer tilts the display monitor 101 downward to confirm the subject on the display monitor 101, thereby rotating the display monitor 101. The operation is detected (step S202 = Yes), and the detection of the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101 (step S203) and the detection of the rotation direction of the display monitor 101 (step S204) Done. The imaging magnification is reduced based on the imaging magnification before the rotation operation of the display monitor 101, the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101, and the rotation direction of the display monitor 101. Then, the driving amount of the zoom lens 13 is calculated (step S205).

  Then, based on the calculated driving amount of the zoom lens 13, an instruction to drive the zoom lens 13 is issued (step S206), and as shown in FIG. 8B (D), the zoom lens 13 is driven to the wide side. As a result, the subject is within the shooting range, and the photographer can check the subject on the display monitor 101.

  Further, in the present embodiment, it is determined whether or not a certain time has elapsed after the zoom lens 13 is driven (step S207). When a certain time has elapsed since the zoom lens 13 was driven (step S207 = Yes), the CPU 5 moves the zoom lens 13 before the rotation operation of the display monitor 101 as shown in FIG. 8C (E). Drive to the position (step S208). Thus, the photographer can photograph the subject at a desired magnification while checking the subject on the display monitor 101 without operating the zoom button. Therefore, the subject can be appropriately selected in high angle shooting or low angle shooting. Can be taken.

  As described above, in the second embodiment, when the display monitor 101 of the display unit 10 is rotated upward or downward, the larger the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101 is, The zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. Accordingly, even in high angle shooting or low angle shooting in which the posture of the photographer is likely to be unstable, the subject can be within the shooting range, and the subject can be appropriately shot. In particular, when the photographer sets the zoom magnification high, the subject is more likely to be out of the shooting range, but in the second embodiment, the optical axis of the camera body 20 and the normal line of the display monitor 101 The zoom lens 13 is driven to the wide side so that the larger the pitch angle is, the smaller the photographing magnification, so that the subject can be photographed even in high-angle photographing or low-angle photographing started with a large photographing magnification. The subject can be accommodated within, and the subject can be appropriately photographed.

  Further, in the second embodiment, when the display monitor 101 is rotated and the zoom lens 13 is driven to the wide side, when the predetermined time has elapsed, the zoom lens 13 is moved before the display monitor 101 is rotated. Drive to the lens position. In this way, in high angle shooting or low angle shooting, after the shooting magnification is reduced and the subject is within the shooting range, the photographer does not operate the zoom button so that the subject does not move out of the shooting range. The subject image can be taken at a desired magnification while confirming the subject on the display monitor 101.

  Furthermore, in the second embodiment, the zoom lens 13 is driven so that the amount of change in the photographing magnification before and after the rotation of the display monitor 101 does not increase as the photographing magnification before rotating the display monitor 101 increases. Thereby, according to the imaging magnification before the rotation operation of the display monitor 101, the imaging magnification after the rotation of the display monitor 101 can be set to an appropriate size. That is, in high angle shooting or low angle shooting, when the zoom lens 13 is driven to the wide side, the shooting magnification can be set to an appropriate size that allows the subject to be shot within the shooting range.

  Further, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification becomes smaller when the display monitor 101 is directed downward than when the display monitor 101 is directed upward. Here, the posture of the photographer tends to be unstable when the electronic camera 100 is held above the photographer's line of sight, rather than when the electronic camera 100 is held below the photographer's line of sight. Therefore, the subject tends to be out of the shooting range due to camera shake. Therefore, when it can be determined that the high-angle shooting is being performed because the display monitor 101 is directed downward, it can be determined that the low-angle shooting is being performed because the display monitor 101 is directed upward. By driving the zoom lens 13 to the wide side so that the shooting magnification becomes smaller than in the case, the subject can be properly placed in the shooting range at the time of high angle shooting in which the posture of the photographer tends to become more unstable. In addition, it is possible to effectively prevent the zoom lens 13 from being unnecessarily driven to the wide side during low-angle shooting.

<< Third Embodiment >>
Next, a third embodiment of the present invention will be described. The electronic camera 100 according to the third embodiment has the same configuration as the electronic camera 100 according to the first embodiment, and is the same as the electronic camera 100 according to the first embodiment, except that it operates as described below. To work.

  Specifically, in the third embodiment, as shown in FIGS. 3A and 3B, the CPU 5 can determine that the display monitor 101 is directed downward and high-angle shooting is being performed. In this case, the zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. Further, the CPU 5 can drive the zoom lens 13 to the wide side so that the photographing magnification decreases as the pitch angle θ between the optical axis of the camera body 20 and the normal line of the display monitor 101 increases.

  In the third embodiment, as shown in FIGS. 4A and 4B, the CPU 5 can determine that the display monitor 101 is directed upward and low-angle shooting is being performed. The zoom lens 13 is driven to the tele side so that the photographing magnification is increased. Further, the CPU 5 can drive the zoom lens 13 to the telephoto side so that the photographing magnification increases as the pitch angle θ between the optical axis of the camera body 20 and the normal line of the display monitor 101 is larger.

  Next, an exemplary operation of the electronic camera 100 according to the third embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing the operation of the electronic camera 100 according to the third embodiment.

  In step S301, as in step S101 of the first embodiment, the relative position of the display surface of the display monitor 101 with respect to the imaging surface of the image sensor 3 is acquired. In step S302, similarly to step S102 of the first embodiment, it is determined whether or not the display monitor 101 is directed downward in the vertical direction, and the display monitor 101 is directed downward in the vertical direction. If it is determined, the process proceeds to step S303. On the other hand, if it is determined that the display monitor 101 is not directed downward in the vertical direction, the process proceeds to step S304.

  In step S303, since it is determined that the display monitor 101 is directed downward in the vertical direction, in the third embodiment, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification is reduced. Is done. In this case, the CPU 5 drives the zoom lens 13 to the wide side so that the photographing magnification decreases as the pitch angle θ between the optical axis and the normal line of the display monitor 101 increases.

  On the other hand, if it is determined in step S302 that the display monitor 101 is not directed downward in the vertical direction, the process proceeds to step S304. In step S304, as in step S104 of the first embodiment, it is determined whether or not the display monitor 101 is directed upward in the vertical direction. If it is determined that the display monitor 101 is directed upward in the vertical direction, the process proceeds to step S305, and the CPU 5 performs a process of driving the zoom lens 13 to the tele side so that the photographing magnification is increased. . In this case, the CPU 5 drives the zoom lens 13 to the telephoto side so that the photographing magnification increases as the pitch angle θ between the optical axis and the normal line of the display monitor 101 increases.

  As described above, the operation of the electronic camera 100 according to the third embodiment is performed.

  As described above, in the third embodiment, when the display monitor 101 is directed downward and it is determined that high-angle shooting is performed, the larger the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101 is, the larger the pitch angle is. The zoom lens 13 is driven to the wide side so that the photographing magnification is reduced. Further, when the display monitor 101 is directed upward and it is determined that low-angle shooting is performed, the shooting magnification is increased as the pitch angle between the optical axis of the camera body 20 and the normal line of the display monitor 101 is increased. Then, the zoom lens 13 is driven to the tele side. Thus, in the third embodiment, as in the first embodiment, it is possible to omit the photographer from performing the zooming operation in an unstable posture, and thus effectively prevent the subject from being out of the shooting range. be able to.

<< 4th Embodiment >>
Next, a fourth embodiment of the present invention will be described. The electronic camera 100a according to the fourth embodiment has the same configuration as that of the electronic camera 100 according to the first embodiment except that the electronic camera 100a has the configuration described below, and operates as described below. It operates similarly to the electronic camera 100 according to the first embodiment.

  FIG. 10 is a block diagram of an electronic camera 100a according to the fourth embodiment. As shown in FIG. 10, in the electronic camera 100a according to the fourth embodiment, the display device 30 can be detached from the camera body 20a.

  The camera body 20 a includes a camera side communication unit 18, and the display device 30 includes a monitor side communication unit 31. The camera body 20a and the display device 30 can exchange information with each other by wireless communication via the camera side communication unit 18 and the monitor side communication unit 31. Accordingly, the camera body 20a transmits the live view image captured by the camera body 20a to the display device 30 via the camera-side communication unit 18, and thus the live view transmitted from the camera body 20a to the display device 30. An image can be displayed on the display monitor 32. The display monitor 32 of the display device 30 includes a touch panel, and the display device 30 transmits a photographer's instruction input on the touch panel of the display monitor 32 to the camera body 20 a via the monitor-side communication unit 31. This allows the camera body 20a to control the operation of the camera body 20a based on an instruction from the photographer.

  Further, the position detection sensor 9 a according to the fourth embodiment includes a GPS unit and a gyro sensor, and detects the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32. For example, the position detection sensor 9a detects the movement of the camera body 20a after the display apparatus 30 is detached from the camera body 20a, assuming that the position of the display device 30 is fixed at a certain position that is easy for the photographer to see. Thus, the relative position of the image sensor 3 with respect to the display monitor 32 can be detected.

  Further, the display device 30 also includes a position detection sensor 9a, and the position detection sensor 9a detects the relative position of the image sensor 3 with respect to the display monitor 32 by detecting the movement of the display device 30 and the camera body 20a. It is good. Further, the display device 30 is also provided with a position detection sensor 9a, and the position detection sensor 9a detects the absolute position of the camera body 20a and the display device 30 at the latitude and longitude and the height (position in the vertical direction). The relative position of the image sensor 3 with respect to 32 may be detected.

  The CPU 5 according to the fourth embodiment controls the driving of the zoom lens 13 included in the camera body 20 a based on the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32. Specifically, when the image pickup device 3 is above the display monitor 32, the CPU 5 determines that high-angle shooting is being performed and moves the zoom lens 13 to the tele side so that the shooting magnification is increased. To drive. On the other hand, when the image pickup device 3 is below the display monitor 32, the CPU 5 determines that low-angle shooting is being performed and drives the zoom lens 13 to the wide side so that the shooting magnification is reduced. .

  Further, the CPU 5 changes the driving amount of the zoom lens 13 according to the distance from the display monitor 32 to the image sensor 3. That is, when the image pickup device 3 is above the display monitor 32, the CPU 5 moves the zoom lens 13 to the telephoto side so that the photographing magnification increases as the distance from the display monitor 32 to the image pickup device 3 increases. Drive. On the other hand, when the image sensor 3 is below the display monitor 32, the CPU 5 moves the zoom lens 13 to the wide side so that the photographing magnification decreases as the distance from the display monitor 32 to the image sensor 3 increases. Drive.

  In addition to the relative position of the image sensor 3 with respect to the display monitor 32, the CPU 5 is taking a high-angle image by the photographer based on the attitude (tilt) of the camera body 20a (image sensor 3) or the low angle. It may be configured that the zoom lens 13 is driven by determining whether shooting is being performed. For example, when it can be determined that the image sensor 3 is above the display monitor 32 and the camera body 20a (image sensor 3) is facing downward, it is determined that high angle shooting is being performed, The zoom lens 13 may be driven to the telephoto side so that the photographing magnification is increased.

  Next, an operation example of the electronic camera 100a according to the fourth embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing the operation of the electronic camera 100a according to the fourth embodiment.

  First, in step S <b> 401, the CPU 5 acquires the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32. In step S402, based on the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 acquired in step S401 by the CPU 5, it is determined whether the imaging device 3 is above the display monitor 32. Judgment is made. If the image pickup device 3 is above the display monitor 32, the process proceeds to step S403, and the zoom lens 13 is moved by the CPU 5 so that the shooting magnification increases as the distance from the display monitor 32 to the image pickup device 3 increases. Processing to drive to the tele side is performed. The CPU 5 can determine that the image sensor 3 is above the display monitor 32 when the distance from the display monitor 32 to the image sensor 3 is equal to or greater than a predetermined distance.

  If it is determined in step S402 that the image sensor 3 is not above the display monitor 32, the process proceeds to step S404. In step S404, the CPU 5 determines whether the image sensor 3 is below the display monitor 32 based on the relative position of the image sensor 3 to the display surface of the display monitor 32 acquired in step S401. Is done. If the image pickup device 3 is below the display monitor 32, the process proceeds to step S404, and the zoom lens 13 is moved by the CPU 5 so that the shooting magnification decreases as the distance from the display monitor 32 to the image pickup device 3 increases. A process of driving to the wide side is performed. Similarly to step S <b> 402, the CPU 5 can determine that the image sensor 3 is below the display monitor 32 when the distance from the display monitor 32 to the image sensor 3 is equal to or greater than a predetermined distance.

  As described above, the operation of the electronic camera 100a according to the fourth embodiment is performed.

  Thus, in the fourth embodiment, in the electronic camera 100a in which the display device 30 can be detached from the camera body 20a, the zoom lens 13 is based on the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32. Control the drive. Specifically, when the image pickup device 3 is above the display monitor 32, it is determined that the shooting is at a high angle, and the shooting magnification is increased as the distance from the display monitor 32 to the image pickup device 3 is increased. The zoom lens 13 is driven to the tele side. On the other hand, when the image pickup device 3 is below the display monitor 32, it is determined that the shooting is at a low angle, and the zoom lens is set so that the shooting magnification decreases as the distance from the display monitor 32 to the image pickup device 3 increases. 13 is driven to the wide side. Thereby, even when the high-angle shooting and the low-angle shooting are performed in the electronic camera 100a in which the display device 30 can be detached from the camera body 20a, it is effective that the subject is out of the shooting range as in the first embodiment. Can be prevented.

<< 5th Embodiment >>
Next, a fifth embodiment of the present invention will be described. The electronic camera 100a according to the fifth embodiment has the same configuration as the electronic camera 100a according to the fourth embodiment, and is the same as the electronic camera 100 according to the second embodiment except that the electronic camera 100a operates as described below. To work.

  The CPU 5 according to the fifth embodiment controls the zoom lens 13 so that the imaging magnification is reduced with respect to the display surface of the display monitor 32, regardless of whether the imaging surface of the imaging device 3 is above or below. Drive to the wide side.

  Further, in the fifth embodiment, the CPU 5 zooms the zoom lens so that the photographing magnification is reduced even when the imaging surface of the imaging device 3 is shifted leftward or rightward with respect to the display surface of the display monitor 32. 13 is driven to the wide side.

  In the fifth embodiment, the display device 30 is also provided with the position detection sensor 9a, and the position detection sensor 9a provided in the camera body 20a detects the inclination of the imaging surface of the image sensor 3 and is provided in the display device 30. The relative position in the left-right direction of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 may be detected by detecting the inclination of the display surface of the display monitor 32 by the position detection sensor 9b. Specifically, it is determined that the photographer exists at a position where the direction opposite to the direction in which the imaging surface of the image sensor 3 faces and the direction in which the display surface of the display monitor 32 faces, and the image sensor 3, the display monitor 32, and the photographer can determine whether the imaging surface of the imaging device 3 is in the right direction or the left direction with respect to the display surface of the display monitor 32. . Further, for example, when the photographer carries a portable terminal such as a smartphone, the positional information of the photographer is acquired from the portable terminal, so that the positional relationship among the imaging element 3, the display monitor 32, and the photographer is obtained. Also, it can be configured to determine whether the imaging surface of the imaging device 3 is in the right direction or the left direction with respect to the display surface of the display monitor 32.

  Thus, in the fifth embodiment, for example, even when the photographer performs shooting while extending the arm holding the camera body 20a leftward or rightward in order to avoid obstacles ahead, the shooting magnification is high. Since the shooting range of the electronic camera 100 becomes smaller and the arm holding the camera body 20a extends leftward or rightward, the photographer's posture becomes unstable and hand shake is likely to occur. Can be easily kept within the shooting range.

  The CPU 5 can drive the zoom lens 13 to the wide side so that the photographing magnification decreases as the distance between the display monitor 32 and the image sensor 3 increases. Further, the posture of the photographer is likely to be unstable when the image pickup device 3 is above or below the display monitor 32 than when the image pickup device 3 is in the left direction or the right direction from the display monitor 32. Because of this tendency, the CPU 5 has a lower shooting magnification when the image sensor 3 is above or below the display monitor 32 than when the image sensor 3 is left or right than the display monitor 32. Thus, the zoom lens 13 can be driven to the wide side.

  Further, in the fifth embodiment, as in the second embodiment, the CPU 5 drives the zoom lens 13 to the wide side according to the relative position of the imaging device 3 with respect to the display monitor 32, and then a certain time has elapsed. In addition, the lens position of the zoom lens 13 driven to the wide side is gradually returned to the lens position before driving. Similarly to the second embodiment, the CPU 5 increases the amount of change in the photographing magnification before and after the change in the relative position of the image sensor 3 as the photographing magnification before the relative position of the image sensor 3 with respect to the display monitor 32 changes is larger. The zoom lens 13 is driven so that it is not large. Further, as in the second embodiment, when the image pickup device 3 is above the display monitor 32, the CPU 5 detects the relative position of the image pickup device 3 as compared with the case where the image pickup device 3 is below the display monitor 32. The zoom lens 13 is driven to the wide side so that the amount of change in the photographing magnification before and after the change in position becomes large.

  Next, an operation example of the electronic camera 100a according to the fifth embodiment will be described with reference to FIG. FIG. 12 is a flowchart showing the operation of the electronic camera 100a according to the fifth embodiment.

  First, in step S <b> 501, the CPU 5 detects the shooting magnification as a shooting magnification before the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 changes. In step S <b> 502, the CPU 5 detects the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32.

  In step S503, the CPU 5 determines whether or not the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 has changed. If the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 has changed, the process proceeds to step S503, while the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 has changed. If not, the process returns to step S501, and the detection of the photographing magnification and the detection of the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 are repeated. In this step S503, when the display surface of the display monitor 32 and the image pickup surface of the image pickup device 3 are changed by a predetermined distance or more, the CPU 5 determines the relative position of the image pickup surface of the image pickup device 3 with respect to the display surface of the display monitor 32. It can be judged that it has changed.

  In step S504, based on the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 detected in step S502, the CPU 5 determines the direction in which the imaging device 3 exists with respect to the display monitor 32. Detected. Specifically, the CPU 5 detects, with respect to the display monitor 32, whether the imaging device 3 exists in the upward, downward, rightward, or leftward direction.

  In step S505, the CPU 5 calculates the driving amount of the zoom lens 13 based on the detection results of steps S501, S502, and S504. Specifically, the CPU 5 determines the photographing magnification before the relative position of the image sensor 3 with respect to the display monitor 32 detected in step S501 changes, and the current relative position of the image sensor 3 with respect to the display monitor 32 detected in step S502. Based on the direction in which the image sensor 3 is present with respect to the display monitor 32 detected in step S504, the target shooting magnification is determined, and the driving amount of the zoom lens 13 is obtained so that the target shooting magnification is obtained. Is calculated. In step S506, the zoom lens 13 is driven based on the driving amount of the zoom lens 13 calculated in step S505.

  In steps S507 and S508, as in steps S207 and S208 of the second embodiment, after the zoom lens 13 is driven, it is determined whether or not a certain time has elapsed, and it is determined that the certain time has elapsed. In the case where the zoom lens 13 is set, the lens position of the zoom lens 13 is returned to the lens position before the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 changes.

  As described above, the operation of the electronic camera 100a according to the fifth embodiment is performed.

  As described above, in the fifth embodiment, in the electronic camera 100a in which the display device 30 can be removed from the camera body 20a, when the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 is changed, the imaging magnification is increased. By driving the zoom lens 13 to the wide side so as to decrease, even when performing high-angle shooting or low-angle shooting, it is possible to appropriately fit the subject within the shooting range as in the second embodiment. Therefore, it is possible to appropriately shoot the subject in high angle shooting or low angle shooting.

<< 6th Embodiment >>
Next, a sixth embodiment of the present invention will be described. The electronic camera 100a according to the sixth embodiment has the same configuration as the electronic camera 100a according to the fourth embodiment, and is the same as the electronic camera 100a according to the fourth embodiment except that the electronic camera 100a operates as described below. To work.

  Specifically, in the sixth embodiment, when it is determined that the imaging device 3 is above the display monitor 32 and the high-angle shooting is performed, the CPU 5 reduces the shooting magnification. Then, the zoom lens 13 is driven to the wide side. On the other hand, when it is determined that the image sensor 3 is below the display monitor 32 and low angle shooting is performed, the CPU 5 drives the zoom lens 13 to the tele side so that the shooting magnification is increased. .

FIG. 13 is a flowchart showing the operation of the electronic camera 100a according to the sixth embodiment.
Hereinafter, an operation example of the electronic camera 100a according to the sixth embodiment will be described with reference to FIG.

  First, in steps S601 and S602, the relative position of the imaging surface of the imaging device 3 with respect to the display surface of the display monitor 32 is acquired (step S601), as in steps S401 and S402 of the fourth embodiment. Whether or not the image sensor 3 is above is determined (step S602).

  If the image pickup device 3 is above the display monitor 32, the process proceeds to step S603, and the zoom lens 13 is moved by the CPU 5 so that the shooting magnification decreases as the distance from the display monitor 32 to the image pickup device 3 increases. A process of driving to the wide side is performed. On the other hand, if the image sensor 3 is not above the display monitor 32, the process proceeds to step S604, and whether or not the image sensor 3 is below the display monitor 32 is the same as in step S404 of the fourth embodiment. Judgment is made. If the imaging device 3 is below the display monitor 32, the process proceeds to step S605, and the CPU 5 causes the zoom lens 13 to be adjusted so that the photographing magnification increases as the distance from the display monitor 32 to the imaging device 3 increases. Processing to drive to the tele side is performed.

  As described above, the operation of the electronic camera 100a according to the sixth embodiment is performed.

  As described above, in the sixth embodiment, in the electronic camera 100a in which the display device 30 can be detached from the camera body 20a, it is determined that the image pickup device 3 is located above the display monitor 32 and high-angle shooting is performed. In this case, the zoom lens 13 is driven to the wide side so that the photographing magnification decreases as the distance from the display monitor 32 to the image sensor 3 increases. When it is determined that the image sensor 3 is below the display monitor 32 and low angle shooting is being performed, the shooting magnification increases as the distance from the display monitor 32 to the image sensor 3 increases. Then, the zoom lens 13 is driven to the wide side. Thus, even when the photographer performs high-angle shooting and low-angle shooting in the electronic camera 100a in which the display device 30 is removable from the camera body 20a, the posture is unstable to the photographer as in the fourth embodiment. Since the zooming operation can be omitted, it is possible to effectively prevent the subject from being out of the shooting range.

  The embodiment described above is described for facilitating the understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  For example, in addition to the above-described embodiment, whether or not a tripod is used is further determined, and if it is determined that a tripod is used, the operation of the electronic cameras 100 and 100a of the above-described embodiment (zoom lens) 13 drive control) may not be performed. This is because camera shake is unlikely to occur when using a tripod. The method for determining whether or not the tripod is used is not particularly limited. For example, whether or not the tripod is used by using a gyro sensor or a sensor that detects the connection between the electronic camera 100 and the tripod is used. Can be determined. Alternatively, when the photographer selects a shooting menu that requires the use of a tripod via the operation unit 8, it can be determined that the tripod is being used.

  In the above-described embodiment, a tracking function for tracking the subject may be further provided, and the driving of the zoom lens 13 may be controlled according to the tracking result of the subject. For example, in the second embodiment described above, the configuration in which the zoom lens 13 is driven to the wide side so that the photographing magnification becomes small when the display monitor 101 is directed upward or downward is exemplified. While the subject can be detected, the zoom lens 13 can be configured not to be driven to the wide side. Similarly, in the first embodiment and the third to sixth embodiments, when the zoom lens 13 is driven to the wide side, the zoom lens 13 is driven to the wide side while the subject can be detected by the tracking function. It can be set as the structure which is not made to do. Even when the subject is detected without using the tracking function, the zoom lens 13 can be configured not to be driven to the wide side while the subject is detected.

  Further, in the second embodiment or the fifth embodiment described above, the configuration in which the operation of returning the zoom lens 13 to the original lens position is started when a predetermined time has elapsed, but is not limited to this configuration. For example, the operation of returning the zoom lens 13 to the original lens position may be started at the timing when the subject is detected by the tracking function.

  Further, in the above-described embodiment, when the zoom lens 13 is driven to the tele side and the subject cannot be detected by the tracking function or normal subject detection, the driving of the zoom lens 13 is temporarily stopped. It is good also as composition to do. In this case, the driving of the zoom lens 13 may be temporarily stopped until the subject is detected again. For example, in the second embodiment and the fifth embodiment described above, the configuration in which the zoom lens 13 is driven to the tele side when a certain time has elapsed after the zoom lens 13 is driven to the wide side has been illustrated. In addition, when the subject cannot be detected, the driving of the zoom lens 13 to the tele side can be temporarily stopped.

  Furthermore, in the second embodiment described above, the zoom lens 13 is driven to the wide side so that the photographing magnification decreases as the pitch angle θ between the optical axis L1 of the camera body 20 and the normal line L2 of the display monitor 101 increases. In addition to or instead of this configuration, the camera body 20 is provided with a sensor for detecting the amount of movement of the camera body 20 such as a gyro sensor, and the amount of movement of the camera body 20 is large. The zoom lens 13 may be driven to the wide side so that the photographing magnification becomes smaller.

  In addition, in the second embodiment or the fifth embodiment described above, when the zoom lens 13 is driven to the wide side so as to reduce the photographing magnification, the subject detection frame is displayed superimposed on the subject. It is good also as a structure displayed on the monitor 101,32. Thereby, even when the zoom lens 13 is driven to the wide side, the photographer can appropriately recognize the subject.

  Furthermore, in the first embodiment and the second embodiment described above, the configuration in which the rotation shafts 102a and 102b are provided on the left side of the camera body 20 is exemplified, but the present invention is not limited to this configuration. For example, the rotation shafts 102a and 102b are provided. The camera body 20 may be provided on the upper side, lower side, or right side.

  Further, in the second embodiment described above, the configuration in which the zoom lens 13 is driven to the wide side so that the photographing magnification becomes small when the display monitor 101 is directed upward or downward is exemplified. In addition, by rotating the display monitor 101 about the rotation axis 102a, the zoom lens 13 is moved to the wide side so that the shooting magnification is reduced even when the display monitor 101 is directed leftward or rightward. It is good also as a structure driven to. Also, in this case, the amount of change in the photographing magnification is larger when the display monitor 101 is directed upward or downward than when the display monitor 101 is directed leftward or rightward. It is preferable to drive the zoom lens 13. Further, in this case, the driving amount of the zoom lens 13 is determined based on the yaw angle in the left or right direction of the display monitor 101 and the pitch angle in the upward or downward direction of the display monitor 101. It is good also as composition to do.

  In addition, in the second embodiment and the fifth embodiment described above, a configuration in which the zoom lens 13 is driven to the original lens position when a certain time has elapsed after the zoom lens 13 is driven to the wide side is illustrated. However, the present invention is not limited to this configuration. For example, the zoom lens 13 may not be driven to the original lens position. Further, when the photographer returns the display unit 10 to the original angle, the zoom lens 13 may be returned to the original lens position. Furthermore, the zoom lens 13 may be configured to return to the lens position on the wide side with respect to the original lens position of the zoom lens 13.

  Further, in the above-described fourth and fifth embodiments, the electronic camera 100a that can be detached from the camera body 20a has been described as an example. However, the display device 30 is not limited to this configuration, and for example, the display device 30. As, it is good also as a structure using a terminal provided with display monitors, such as a smart phone and a tablet terminal. In this case, the camera body 20 may be configured to include the display unit 10 as shown in FIG. 1, for example, or may be configured to not include the display unit 10 as shown in FIG.

  Furthermore, in embodiment mentioned above, although the structure provided with the zoom button in the camera main body 20 was illustrated, it is not limited to this structure, For example, the display part 10 or the display apparatus 30 is provided with a touch panel, and by operating a touch panel, It is good also as a structure which performs a zooming operation | movement. For example, in the second embodiment and the fifth embodiment, the configuration in which the zoom lens 13 is driven to the original lens position when a certain time has elapsed after the zoom lens 13 is driven to the wide side has been exemplified. When a certain time has elapsed, a zoom button is displayed on the touch panel, whereby the photographer can operate the touch panel to return the zoom lens 13 to the original lens position. In this case, the photographer is relatively difficult to operate in high angle shooting or low angle shooting, and is relatively easy to operate in high angle shooting or low angle shooting instead of the zoom button installed on the camera body 20. A zooming operation can be performed by operating a zoom button displayed on the touch panel.

  In the above-described embodiment, the operation of the electronic camera 100, 100a of the above-described embodiment is performed only when a mode for performing the operation of the electronic camera 100, 100a of the above-described embodiment is set by the photographer. It is good also as a structure to perform.

  Further, in the first embodiment described above, for example, when the photographer turns the display monitor 101 from the lower side in the vertical direction toward the photographer's line-of-sight direction el in order to return from high-angle shooting to the photographer's line-of-sight Contrary to the case where the display monitor 101 is directed downward in the vertical direction, the zoom lens 13 may be driven to the wide side so that the photographing magnification is reduced. Similarly, when the photographer turns the display monitor 101 from above in the vertical direction to the photographer's line-of-sight direction el in order to return from low-angle shooting to shooting at the photographer's line of sight, the display monitor 101 is in the vertical direction. Contrary to the case where it is directed upward, the zoom lens 13 may be driven to the tele side so that the photographing magnification is increased. Similarly, in other embodiments, when the photographer returns from high-angle shooting to shooting at the photographer's line of sight, or when returning from low-angle shooting to shooting at the photographer's line of sight, high-angle shooting is performed. Alternatively, the zoom lens 13 can be driven in the opposite direction to the case where low-angle shooting is performed.

  Note that the electronic camera 100 of the above-described embodiment is not particularly limited, and the present invention may be applied to other optical devices such as a lens interchangeable camera and a mobile phone camera.
