DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] [First embodiment] As an example, as shown in FIG. 1 and FIG. 2, the imaging device 10 is, for example, a compact digital camera and includes a device body 11. The device body 11 is a basic part of the imaging device 10 and is not a separate part. An imaging lens 13, an objective window 15 of a hybrid viewfinder 14, an image switching lever 16 of the hybrid viewfinder 14, and the like are arranged on a front surface 12 of the device body 11. In addition, a liquid crystal monitor 18, an eyepiece window 19 of the hybrid viewfinder 14, a diopter adjustment dial 20 of the hybrid viewfinder 14, a detection window 21, various operation buttons 22, and the like are arranged on a back surface 17 of the device body 11 facing the front surface 12. Furthermore, various operation members such as a power switch integrated release button 24 are arranged on a top surface 23 of the device body 11 connecting the front surface 12 and the back surface 17. The imaging device 10 may be a lens-interchangeable digital camera in which the imaging lens 13 is interchangeable.

[0026] The imaging lens 13 is disposed at approximately the center of the front surface 12. Meanwhile, the hybrid viewfinder 14 is disposed at the upper right end of the front surface 12. Therefore, the optical axis OAL of the imaging lens 13 is different from the optical axis OAF of the hybrid viewfinder 14. Due to the difference between the optical axis OAL and the optical axis OAF, a deviation occurs between the angle of view (imaging range) AV (see FIG. 12) of the image and the optical image (visible range) OI (see FIG. 3, etc.) by the hybrid viewfinder 14. This deviation is called parallax or parallax. In the following description, unless otherwise specified, the term "deviation" refers to the deviation between the angle of view AV of the image and the optical image OI by the hybrid viewfinder 14. The hybrid viewfinder 14 is an example of an "optical viewfinder" according to the technology of the present disclosure.

[0027] An imaging element 25 is disposed behind the imaging lens 13. The imaging element 25 is, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor. The imaging element 25 has a rectangular imaging surface 26 that captures an image of a subject. Two orthogonal sides of the imaging surface 26 are parallel to the Y-axis direction and the Z-axis direction, respectively. The center of the imaging surface 26 coincides with the optical axis OAL of the imaging lens 13. The imaging surface 26 receives subject light. As is well known, pixels that photoelectrically convert the received subject light and output it as an electrical signal are two-dimensionally arranged along the Y-axis direction and the Z-axis direction on the imaging surface 26.

[0028] Here, when the bottom surface 27 of the device body 11 facing the top surface 23 is placed on a horizontal surface, the Y-axis direction is the horizontal direction and the Z-axis direction is the vertical direction. The Y-axis direction is the width direction of the device body 11, and the Z-axis direction is the height direction of the device body 11. In addition, the term "orthogonal" related to angles includes the meaning of almost orthogonal including an error allowable in design and manufacturing, for example, an error of about ±10% of the design value, in addition to the meaning of completely orthogonal. Furthermore, the term "parallel" also includes the meaning of almost parallel including an error allowable in design and manufacturing, for example, an error of about ±10% of the design value, in addition to the meaning of completely parallel. Furthermore, the term "match" also includes the meaning of almost match including an error allowable in design and manufacturing, for example, an error of about ±10% of the design value, in addition to the meaning of completely matching.

[0029] The imaging element 25 is provided with a mechanical shake correction unit 28 for correcting blur of the subject image caused by vibrations applied to the device body 11. The mechanical shake correction unit 28 has a fixed part fixed inside the device body 11, a movable part to which the imaging element 25 is attached, and an actuator such as a voice coil motor that moves the movable part along the YZ plane relative to the fixed part. The mechanical shake correction unit 28 is an example of a "shake correction unit" according to the technology of the present disclosure.

[0030] Here, "blur" refers to a phenomenon that occurs when the optical axis OAL fluctuates relative to the subject image due to vibration. "Fluctuation of the optical axis OAL" means, for example, that the optical axis OAL tilts due to blur with respect to a reference axis (for example, the optical axis OAL before the blur occurs). "Blur correction" includes the meaning of reducing blur in addition to eliminating blur.

[0031] A grip section 29 is provided on the left side of the front surface 12, on which the user's right hand is placed when taking a picture or the like. An angular velocity sensor 30 is disposed in the grip section 29 to detect the amount of vibration (shake) applied to the device body 11. One angular velocity sensor 30 is provided for each of the three axes of pitch, yaw, and roll. The angular velocity sensor 30 is an example of a "detection sensor" according to the technology of the present disclosure. In this example, the roll axis is the X axis, the pitch axis is the Y axis, and the yaw axis is the Z axis. The angular velocity sensor 30 for the roll axis detects the amount of rotation around the X axis, which is the roll axis, that is, the amount of lateral vibration (lateral shake). The angular velocity sensor 30 for the pitch axis detects the amount of rotation around the Y axis, which is the pitch axis, that is, the amount of vertical vibration (vertical shake). The angular velocity sensor 30 for the yaw axis detects the amount of rotation around the Z axis, which is the yaw axis, that is, the amount of yaw vibration (lateral shake). In the following description, the amount of vibration (shake) detected by the angular velocity sensor 30 is referred to as a shake amount 102 (see FIG. 9). The shake amount 102 is an example of a "shake state" according to the technology of the present disclosure. The X-axis direction is a direction perpendicular to the Y-axis and Z-axis directions, and is a horizontal direction like the Y-axis direction when the bottom surface 27 of the device body 11 is placed on a horizontal surface. The X-axis direction is the depth direction of the device body 11.

[0032] A detection sensor 31 is disposed behind the detection window 21. The detection sensor 31 is, for example, a reflective infrared photosensor, and detects whether or not the user's eye 46 (see FIGS. 3 and 4) has approached the eyepiece window 19. In other words, the detection sensor 31 detects whether or not the user is looking into the hybrid viewfinder 14. When shooting, if the detection sensor 31 detects that the user is not looking into the hybrid viewfinder 14, a live view image (also called a through image) is displayed on the LCD monitor 18. On the other hand, when shooting, if the detection sensor 31 detects that the user is looking into the hybrid viewfinder 14, the LCD monitor 18 is turned off.

[0033] A screw hole 32 for attaching a fixture such as a tripod is formed in the center of the bottom surface 27. When a user wishes to take a stable image with minimal blurring, the user screws the screw of the fixture into the screw hole 32 and attaches the fixture to the device body 11. Note that the fixture may be a monopod, a stand, a folding umbrella, or the like, in addition to the tripod shown as an example.

[0034] As an example, as shown in Figures 3 and 4, the hybrid viewfinder 14 has, in addition to the objective window 15 and eyepiece window 19 mentioned above, a finder LCD monitor 40, an electronic image lens 41, an objective lens 42, a finder shutter 43, a half mirror 44, and an eyepiece lens 45.

[0035] The viewfinder LCD monitor 40 displays an electronic image EI. The viewfinder LCD monitor 40 is an example of a "display unit" according to the technology of the present disclosure. The electronic image EI includes an electronic image EIA for displaying various information and an electronic image EIB for displaying a live view image (see also FIGS. 5 and 6). The electronic image lens 41 guides the electronic image EI to a half mirror 44.

[0036] The objective lens 42 is a concave lens, which guides an optical image (subject image) OI incident through the objective window 15 to a half mirror 44. A finder shutter 43 is disposed between this objective lens 42 and the objective window 15. The finder shutter 43 opens as shown in FIG. 3 or closes as shown in FIG. 4 in conjunction with the operation of the image switching lever 16. Depending on whether the finder shutter 43 is opened or closed, the image that the user sees through the hybrid viewfinder 14 by the user's eye 46 looking through the eyepiece window 19 is switched between the optical image OI (strictly speaking, a composite image CI of the optical image OI and the electronic image EIA) and the electronic image EIB. In other words, the hybrid viewfinder 14 has the functions of both an optical viewfinder and an electronic viewfinder.

[0037] The half mirror 44 is formed by joining two right-angle prisms. In the state shown in FIG. 3 in which the finder shutter 43 is open, the optical image OI from the objective lens 42 is incident on the half mirror 44, and the electronic image EIA from the lens for electronic image 41 is incident on the half mirror 44. The half mirror 44 functions as an optical element for generating a composite image CI of the optical image OI and the electronic image EIA. The half mirror 44 outputs the composite image CI toward the eyepiece 45. On the other hand, in the state shown in FIG. 4 in which the finder shutter 43 is closed, the optical image OI from the objective lens 42 is blocked by the finder shutter 43 and does not enter the half mirror 44, and only the electronic image EIB from the lens for electronic image 41 is incident on the half mirror 44. The half mirror 44 outputs the electronic image EIB toward the eyepiece 45.

[0038] The eyepiece 45 is a convex lens, and guides the composite image CI or the electronic image EIB from the half mirror 44 to the eyepiece window 19. The convex eyepiece 45 and the concave objective lens 42 constitute an inverted Galilean optical viewfinder. The optical axis OAF of the hybrid viewfinder 14 is an axis that passes through the centers of the objective lens 42, eyepiece 45, etc.

[0039] As an example, as shown in Fig. 5, in addition to text information indicating shooting conditions such as shutter speed, aperture value, and ISO (International Organization for Standardization) sensitivity, a frame 50 indicating the angle of view AV of the image is displayed on the electronic image EIA. Therefore, a frame 50 indicating the angle of view AV of the image is also displayed on a composite image CI of the optical image OI and the electronic image EIA. The frame 50 is an example of an "indicator" according to the technology of the present disclosure. Note that instead of the frame 50, bracket-shaped marks indicating the four corners of the angle of view AV of the image may be displayed as "indicators".

[0040] 6, the electronic image EIB does not display a frame 50 as in the composite image CI, but displays a live view image together with text information indicating the shooting conditions. The live view image of the electronic image EIB is an example of an "image displayed by the display unit" according to the technology of the present disclosure.

[0041] As an example, as shown in FIG. 7, the imaging lens 13 has a plurality of kinds of lenses for forming a subject image on the imaging element 25. Specifically, the imaging lens 13 has an objective lens 55, a focus lens 56, and a zoom lens 57. These lenses 55-57 are arranged in this order from the object side (subject side) toward the image formation side (imaging element 25 side). Although simplified in FIG. 7, each of the lenses 55-57 is actually a lens group in which a plurality of lenses are combined. The imaging lens 13 also has an aperture 58. The aperture 58 is arranged on the imaging lens 13 closest to the image formation side. The optical axis OAL of the imaging lens 13 is an axis passing through the centers of the objective lens 55, the focus lens 56, the zoom lens 57, etc.

[0042] The focus lens 56 is provided with a focus lens drive mechanism 59, the zoom lens 57 is provided with a zoom lens drive mechanism 60, and the diaphragm 58 is provided with an diaphragm opening adjustment mechanism 61.

[0043] The focus lens driving mechanism 59 includes a focus cam ring that holds the focus lens 56 and has a cam groove formed on its outer periphery, a focus motor that rotates the focus cam ring around the optical axis OAL to move the focus cam ring along the optical axis OAL, and a driver for the focus motor. Similarly, the zoom lens driving mechanism 60 includes a zoom cam ring that holds the zoom lens 57 and has a cam groove formed on its outer periphery, a zoom motor that rotates the zoom cam ring around the optical axis OAL to move the zoom cam ring along the optical axis OAL, and a driver for the zoom motor. The focus cam ring and the zoom cam ring can also be rotated manually by the user from outside the lens barrel. That is, the imaging device 10 can adjust the focus and change the focal length electrically by the focus motor and the zoom motor, or manually by the user.

[0044] The aperture 58 is, for example, an iris aperture, and is configured by combining a plurality of aperture blades. The aperture 58 adjusts the amount of light passing through by simultaneously moving the aperture blades using a cam mechanism to open and close a central opening formed by the inner edges of the aperture blades, i.e., by changing the opening degree of the opening. The aperture opening adjustment mechanism 61 includes an aperture motor that opens and closes the aperture blades, and a driver for the aperture motor, etc. The aperture 58 can also be opened and closed manually by the user. In other words, the imaging device 10 can adjust the opening degree of the aperture 58 electrically using the aperture motor, or manually by the user.

[0045] The various motors such as the focus motor, zoom motor, and aperture motor are, for example, stepping motors. In this case, the positions of focus lens 56 and zoom lens 57 on the optical axis OAL and the opening degree of aperture 58 can be derived from the drive amounts of the focus motor, zoom motor, and aperture motor. Note that instead of the drive amounts of the focus motor and zoom motor, position sensors may be provided to detect the positions of focus lens 56 and zoom lens 57.

[0046] The motors (focus motor, zoom motor, and aperture motor) or electric components such as drivers of the drive mechanisms 59-61 are connected to the control unit 65. The electric components of the drive mechanisms 59-61 are driven under the control of the control unit 65. More specifically, the control unit 65 issues a drive signal according to an instruction from a user input via the operation unit 66 to drive the electric components of the drive mechanisms 59-61. For example, when an instruction to change the angle of view to the telephoto side is input via a view angle change switch included in the operation unit 66, the control unit 65 issues a drive signal to a driver of the zoom motor of the zoom lens drive mechanism 60 to move the zoom lens 57 to the telephoto side.

[0047] The operation unit 66 is a collective term for members operated by the user, such as the image switching lever 16, the diopter adjustment dial 20, the various operation buttons 22, and the power switch-integrated release button 24. Here, the power switch-integrated release button 24 is a two-stage push button that can be pressed halfway or fully. Pressing the power switch-integrated release button 24 halfway issues an instruction to prepare for shooting a still image or a video, and pressing it fully issues an instruction to start shooting a still image or a video.

[0048] The operation unit 66 also includes a mode changeover switch for switching the operation mode of the imaging device 10. The operation modes include a still image shooting mode, a video shooting mode, an image playback mode, and a setting mode. The still image shooting modes include a normal shooting mode in which one still image is shot, as well as a continuous shooting mode in which still images are shot continuously at a predetermined shooting interval (for example, a frame rate of 5 fps to 10 fps). The continuous shooting mode is activated, for example, when the power switch-integrated release button 24 is fully pressed for a predetermined time or more (for example, one second or more). The continuous shooting mode ends when the power switch-integrated release button 24 is released from the fully pressed state.

[0049] The focus motor, zoom motor, and iris motor output their drive amounts to the control unit 65. The control unit 65 derives the position of the focus lens 56 on the optical axis OAL, the position of the zoom lens 57, and the opening degree of the iris 58 from the drive amounts.

[0050] An imaging element driver 67 is connected to the imaging element 25. The imaging element driver 67 is connected to the control unit 65. Under the control of the control unit 65, the imaging element driver 67 controls the timing at which the imaging element 25 captures an image of a subject by, for example, supplying a vertical scanning signal and a horizontal scanning signal to the imaging element 25.

[0051] A correction unit driver 68 is connected to the mechanical shake correction unit 28. The correction unit driver 68 is connected to the control unit 65. The correction unit driver 68 outputs a control signal 104 (see FIG. 9) from the control unit 65 to an actuator such as a voice coil motor of the mechanical shake correction unit 28, thereby operating the mechanical shake correction unit 28.

[0052] A shutter 69 is provided between the imaging lens 13 and the imaging element 25. The shutter 69 is, for example, a focal plane shutter having a front curtain and a rear curtain. A shutter drive mechanism 70 is connected to the shutter 69. The shutter drive mechanism 70 includes an electromagnet that holds the front curtain and the rear curtain and releases the hold to cause the front curtain and the rear curtain to run, and a driver for the electromagnet. The shutter drive mechanism 70 is driven under the control of the control unit 65 to open and close the shutter 69.

[0053] The control unit 65 is connected to each unit such as an image input controller 73, an image memory 74, and an image processing unit 75 through a bus line 76. In addition, a VRAM (Video Random Access Memory) 77, a display control unit 78, a media controller 79, an instruction receiving unit 80, etc. are connected to the bus line 76. Although not shown in the figure, the bus line 76 is also connected to a strobe drive control unit that controls the drive of the strobe device, an external communication I / F (Interface) that communicates with an external device via a connection terminal such as a USB (Universal Serial Bus) terminal, or a wireless communication I / F that communicates with an external device via a wireless antenna, etc.

[0054] Image data obtained by capturing an image of a subject is input to the image input controller 73 from the imaging element 25. The image input controller 73 outputs the image data to an image memory 74. The image memory 74 is, for example, a Synchronous Dynamic Random Access Memory (SDRAM), and temporarily stores the image data.

[0055] The image processing unit 75 reads unprocessed image data from the image memory 74. The image processing unit 75 performs various image processing on the image data. The various image processing includes, for example, offset correction processing, sensitivity correction processing, pixel interpolation processing, white balance correction processing, gamma correction processing, demosaic processing, luminance signal and color difference signal generation processing, contour enhancement processing, color correction processing, etc. The image processing unit 75 writes the image data after the various image processing back to the image memory 74.

[0056] The VRAM 77 receives image data after various image processes, which is to be displayed as a live view image, from the image memory 74. The VRAM 77 has an area for storing image data for two consecutive frames. The image data stored in the VRAM 77 is sequentially rewritten with new image data. The VRAM 77 sequentially outputs the newer image data of the two consecutive frames of image data to the display control unit 78.

[0057] The display control unit 78 functions as a so-called video encoder, converting image data from the VRAM 77 into video data and outputting it to either the liquid crystal monitor 18 or the finder liquid crystal monitor 40 of the hybrid viewfinder 14. This allows the user to view a live view image through either the hybrid viewfinder 14 or the liquid crystal monitor 18. The display frame rate of the live view image is, for example, 60 fps (frames per seconds).

[0058] When the detection sensor 31 detects that the user is not looking through the hybrid viewfinder 14, the display control unit 78 outputs video data of the live view image to the LCD monitor 18. On the other hand, when the electronic image EIB is selected by the image switching lever 16 and the detection sensor 31 detects that the user is looking through the hybrid viewfinder 14, the display control unit 78 outputs video data of the live view image to the viewfinder LCD monitor 40.

[0059] When an instruction to start shooting a still image or a video is issued by fully pressing the power switch-integrated release button 24, the image processing unit 75 performs a compression process on the image data in the image memory 74. In the case of a still image, the image processing unit 75 performs a compression process on the image data in, for example, the Joint Photographic Experts Group (JPEG) format. In the case of a video, the image processing unit 75 performs a compression process on the image data in, for example, the Moving Picture Experts Group (MPEG) format. The image processing unit 75 outputs the compressed image data to the media controller 79.

[0060] The media controller 79 records the compressed image data from the image processing unit 75 on a memory card 81. The memory card 81 is detachably attached to a memory card slot (not shown). The memory card 81 is an example of a "recording unit" according to the technology of the present disclosure. The recording unit may be an internal memory that is non-removably provided in the device body 11.

[0061] When the image playback mode is selected via the mode changeover switch of the operation unit 66, the media controller 79 reads image data from the memory card 81 and outputs it to the image processing unit 75. The image processing unit 75 performs decompression processing on the image data from the memory card 81. The decompressed image data is output to the display control unit 78. The display control unit 78 converts the image data into video data and outputs it to the liquid crystal monitor 18. This allows the user to view the played back image through the liquid crystal monitor 18.

[0062] The instruction receiving unit 80 receives various operation instructions input by the user via the operation unit 66 and a touch panel 82 provided integrally with the liquid crystal monitor 18. The instruction receiving unit 80 outputs the received various operation instructions to the control unit 65 via the bus line 76. The touch panel 82 is superimposed on the display surface of the liquid crystal monitor 18. The touch panel 82 recognizes various operation instructions from the user by detecting contact with a dedicated indicator such as the user's finger or a stylus pen.

[0063] 8, the control unit 65 includes a storage 90, a CPU (Central Processing Unit) 91, and a memory 92. The storage 90, the CPU 91, and the memory 92 are interconnected via a bus line 93.

[0064] The storage 90 is a non-volatile storage device such as an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage 90 stores various programs and various data associated with the programs. Instead of the EEPROM, the storage 90 may be a Ferroelectric Random Access Memory (FeRAM) or a Magnetoresistive Random Access Memory (MRAM).

[0065] The memory 92 is a work memory for the CPU 91 to execute processing. The CPU 91 loads a program stored in the storage 90 into the memory 92 and executes processing according to the program. In this way, the CPU 91 comprehensively controls each unit of the imaging device 10. The memory 92 may be built into the CPU 91.

[0066] 9, an operating program 95 is stored in the storage 90. The operating program 95 is a program for causing the CPU 91 to perform various controls such as a control for correcting blur (hereinafter referred to as blur correction control) and a control for reducing deviation (hereinafter referred to as deviation reduction control). In addition to the operating program 95, the storage 90 also stores a threshold value 96 and deviation reduction position information 97.

[0067] When the operating program 95 is started, the CPU 91, in cooperation with the memory 92 and the like, functions as a determination unit 100 and a blur correction control unit 101. The determination unit 100 is an example of a "first determination unit" according to the technology of the present disclosure. The blur correction control unit 101 is an example of a "control unit" according to the technology of the present disclosure.

[0068] The determination unit 100 receives a threshold value 96 from the storage 90 and a blur amount 102 from the angular velocity sensor 30. The determination unit 100 determines the degree of blur correction (hereinafter referred to as blur correction). More specifically, the determination unit 100 determines whether or not blur correction is necessary by comparing the threshold value 96 with the blur amount 102 to determine the degree of blur correction. The determination unit 100 outputs a determination result 103 as to whether or not blur correction is necessary to the blur correction control unit 101.

[0069] The blur correction control unit 101 receives deviation reduction position information 97 from the storage 90 and a blur amount 102 from the angular velocity sensor 30. Furthermore, the blur correction control unit 101 receives a determination result 103 from the determination unit 100. The deviation reduction position information 97 has deviation reduction positions registered therein. The deviation reduction positions are positions on the YZ plane of the imaging element 25 that reduce deviation between the angle of view AV of the image and the optical image OI captured by the hybrid viewfinder 14. The deviation reduction positions are set in advance based on the positional relationship between the optical axis OAL of the imaging lens 13 and the optical axis OAF of the hybrid viewfinder 14. The deviation reduction position may be one point, or may be any point within a preset area.

[0070] The blur correction control unit 101 generates a control signal 104 for controlling the operation of the mechanical blur correction unit 28, according to the deviation reduction position information 97, the blur amount 102, and the determination result 103. The blur correction control unit 101 outputs the control signal 104 to the correction unit driver 68.

[0071] As an example, as shown in FIG. 10, when the amount of shake 102 is equal to or greater than the threshold value 96, more specifically, when at least one of the amounts of shake 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than the threshold value 96, the determination unit 100 outputs a determination result 103 indicating that shake correction is necessary to the shake correction control unit 101. In this case, the shake correction control unit 101 performs shake correction control. The shake correction control is a control for moving the image sensor 25 to a position where shake is corrected (hereinafter, referred to as a shake correction position). The shake correction position is derived from the amount of shake 102. The shake correction control unit 101 issues a control signal 104 for moving the image sensor 25 to the shake correction position. At this time, the mechanical shake correction unit 28 moves the image sensor 25 by moving a movable part only within a preset movable range based on the deviation reduction position.

[0072] On the other hand, as shown in Fig. 11 as an example, if the amount of blur 102 is less than the threshold value 96, more specifically, if all of the amounts of blur 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96, the determination unit 100 outputs a determination result 103 indicating that blur correction is not necessary to the blur correction control unit 101. In this case, the blur correction control unit 101 performs deviation reduction control. The deviation reduction control is control for moving the image sensor 25 to a deviation reduction position. The blur correction control unit 101 issues a control signal 104 for moving the image sensor 25 to the deviation reduction position.

[0073] As an example, as shown in FIG. 12A, when the displacement reduction control is not performed, the angle of view AV of the image and the optical image OI by the hybrid viewfinder 14 are displaced due to the difference between the optical axis OAL and the optical axis OAF. More specifically, the center OIC of the optical image OI and the center AVC of the angle of view AV are displaced by the amount of the displacement between the optical axis OAL and the optical axis OAF. Therefore, in the displacement reduction control, as shown in FIG. 12B, the image sensor 25 is moved so that the center AVC of the angle of view AV coincides with the center OIC of the optical image OI. When the displacement reduction position is one point, the position where the center AVC of the angle of view AV coincides with the center OIC of the optical image OI is the displacement reduction position. When the displacement reduction position is an arbitrary point within a preset region, for example, an arbitrary point within a circular region of a preset radius centered on the center OIC of the optical image OI is the displacement reduction position. The radius of the circular region is set to a value that does not make the user feel uncomfortable with the displacement between the angle of view AV and the optical image OI. As mentioned above, the term "match" used here not only means perfect match, but also includes an approximate match that includes an allowable error in design and manufacturing, such as an error of about ±10% of the design value.

[0074] Next, the operation of the above configuration will be described with reference to the flowchart shown in Fig. 13 as an example. The CPU 91 of the control unit 65 functions as a determination unit 100 and a blur correction control unit 101 by starting the operating program 95 as shown in Fig. 9.

[0075] A user operates power switch-integrated release button 24 to turn on the power of imaging device 10 (step ST100). When the power is turned on, blur correction control unit 101 performs displacement reduction control, and mechanical blur correction unit 28 is operated in response to control signal 104 from blur correction control unit 101, and imaging element 25 is moved to a displacement reduction position (step ST110).

[0076] The amount of blur 102 is detected by the angular velocity sensor 30 (step ST120). The amount of blur 102 is output to the determination unit 100 and the blur correction control unit 101. The determination unit 100 compares the threshold value 96 with the amount of blur 102, and determines whether or not blur correction is necessary (step ST130).

[0077] If the amount of blur 102 is equal to or greater than the threshold value 96 (YES in step ST130), blur correction control is performed by blur correction control unit 101 (step ST140), as shown in Fig. 10. Specifically, mechanical blur correction unit 28 is operated in response to control signal 104 from blur correction control unit 101, and image sensor 25 is moved to the blur correction position based on the deviation reduction position.

[0078] On the other hand, if the amount of blur 102 is less than the threshold value 96 (NO in step ST130), as shown in Figs. 11 and 12, the blur correction control unit 101 performs the displacement reduction control, and the mechanical blur correction unit 28 is operated in response to the control signal 104 from the blur correction control unit 101 to move the image sensor 25 to the displacement reduction position (step ST110). That is, the image sensor 25 continues to stay at the displacement reduction position until the amount of blur 102 becomes equal to or greater than the threshold value 96. In this way, the displacement reduction control is performed when the power is turned on, and the image sensor 25 continues to stay at the displacement reduction position until the amount of blur 102 becomes equal to or greater than the threshold value 96. Therefore, when correcting the blur, the mechanical blur correction unit 28 always moves the image sensor 25 based on the displacement reduction position to which the image sensor 25 was moved in the displacement reduction control as a reference.

[0079] The processes of steps ST110 to ST140 are repeatedly performed as long as the user does not operate the power switch-integrated release button 24 to turn off the power of the imaging device 10 (NO in step ST150).

[0080] As described above, the imaging device 10 includes the imaging element 25 that captures the subject image formed by the imaging lens 13 and outputs the image, the hybrid viewfinder 14 that has an optical axis different from that of the imaging lens 13, the mechanical blur correction unit 28 that corrects blur of the subject image, and the blur correction control unit 101 that controls the operation of the mechanical blur correction unit 28. The blur correction control unit 101 performs control to reduce the deviation between the angle of view AV of the image and the optical image OI by the hybrid viewfinder 14 caused by the difference between the optical axes OAL and OAF, that is, deviation reduction control. Since the deviation reduction control is performed using the existing mechanical blur correction unit 28, it is possible to obtain an image close to the optical image OI by the hybrid viewfinder 14 without providing a dedicated mechanism. It is possible to reduce the risk that a scene different from the scene viewed through the hybrid viewfinder 14 is captured in the image, causing the user to feel uncomfortable.

[0081] The camera includes an angular velocity sensor 30 that detects a blur amount 102 as a state of blur, and a determination unit 100 that determines the degree of blur correction based on the detected blur amount 102. A blur correction control unit 101 performs deviation reduction control based on a determination result 103 by the determination unit 100. More specifically, the determination unit 100 compares the blur amount 102 with a preset threshold value 96 to determine whether blur correction is necessary as the determination of the degree of blur correction. Therefore, when blur correction is not necessary, the mechanical blur correction unit 28, which has conventionally played no role, can be effectively utilized. On the other hand, when blur correction is necessary, the mechanical blur correction unit 28 can be made to perform blur correction, which is its original function.

[0082] The blur correction unit is a mechanical blur correction unit 28 that corrects blur by moving the image sensor 25. The blur correction control unit 101 performs displacement reduction control by moving the image sensor 25. The mechanical blur correction unit 28 is equipped as standard in general imaging devices. Therefore, the mechanical blur correction unit 28 can be used for displacement reduction control without any barriers.

[0083] 10 and 13, when performing blur correction, mechanical blur correction unit 28 moves image sensor 25 with reference to the displacement reduction position. More specifically, when performing blur correction, mechanical blur correction unit 28 moves image sensor 25 with reference to the displacement reduction position to which image sensor 25 was moved in the displacement reduction control. This makes it possible to further increase the possibility of obtaining an image close to the optical image OI captured by hybrid viewfinder 14.

[0084] 5, a frame 50 that is an indicator of the angle of view AV is displayed on the hybrid viewfinder 14. This allows the user to easily estimate the angle of view AV and shoot at the angle of view AV that he or she desires.

[0085] [Second embodiment] In the first embodiment, the mechanical blur correction unit 28 that performs blur correction by moving the image sensor 25 has been exemplified, but the present invention is not limited to this. As an example, as in an image pickup device 110 shown in Fig. 14, a mechanical blur correction unit 113 that performs blur correction by moving a blur correction lens 112 of an image pickup lens 111 may be used.

[0086] The imaging lens 111 has a blur correction lens 112 in addition to the objective lens 55, focus lens 56, zoom lens 57, etc. of the imaging lens 13 of the first embodiment. A mechanical blur correction unit 113 is connected to this blur correction lens 112. The mechanical blur correction unit 113 has a fixed part fixed in the device body 11, a movable part to which the blur correction lens 112 is attached, and an actuator such as a voice coil motor that moves the movable part along the YZ plane relative to the fixed part. The mechanical blur correction unit 113 is an example of a "blur correction unit" according to the technology of the present disclosure. Note that the blur correction lens 112 is actually a lens group formed by combining a plurality of lenses, similar to the focus lens 56, etc.

[0087] A correction unit driver 114 is connected to the mechanical shake correction unit 113. The correction unit driver 114 is connected to the control unit 65. The correction unit driver 114 outputs a control signal 104 from the control unit 65 to an actuator such as a voice coil motor of the mechanical shake correction unit 113, thereby operating the mechanical shake correction unit 113.

[0088] 15, when at least one of the shake amounts 102 detected by angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than threshold value 96 and the determination unit 100 determines that shake correction is necessary, the shake correction control unit 101 performs shake correction control to move the shake correction lens 112 to a shake correction position. The shake correction control unit 101 issues a control signal 104 for moving the shake correction lens 112 to the shake correction position. At this time, the mechanical shake correction unit 113 moves the shake correction lens 112 based on the deviation reduction position, as in the first embodiment.

[0089] 16, when all of the shake amounts 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96 and the determination unit 100 determines that shake correction is not necessary, the shake correction control unit 101 performs deviation reduction control to move the shake correction lens 112 to a deviation reduction position. The shake correction control unit 101 issues a control signal 104 to move the shake correction lens 112 to the deviation reduction position.

[0090] Thus, in the second embodiment, the blur correction unit is a mechanical blur correction unit 113 that corrects blur by moving the blur correction lens 112. The blur correction control unit 101 performs deviation reduction control by moving the blur correction lens 112. Like the mechanical blur correction unit 28 in the first embodiment, the mechanical blur correction unit 113 is equipped as standard in general imaging devices. For this reason, the mechanical blur correction unit 113 can be used for deviation reduction control without any barriers.

[0091] It is also possible to use both mechanical blur correction unit 28 that performs blur correction by moving image sensor 25, and mechanical blur correction unit 113 that performs blur correction by moving blur correction lens 112. In this case, mechanical blur correction unit 28 and mechanical blur correction unit 113 cooperate to perform blur correction control and deviation reduction control.

[0092] [Third embodiment] 17, an electronic blur correction unit 121 is connected to a bus line 76 of an imaging device 120 of the third embodiment in addition to an image processing unit 75, a display control unit 78, etc. The electronic blur correction unit 121 performs blur correction by changing the area to be cut out from the image output by the imaging element 25 in accordance with the blur.

[0093] As an example, as shown in Figures 18 and 19, when at least one of the blur amounts 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than the threshold value 96 and the judgment unit 100 judges that blur correction is necessary, the blur correction control unit 101 performs blur correction control to cause the electronic blur correction unit 121 to cut out an area CA in which blur correction is to be performed from the image IMG.

[0094] On the other hand, as an example, as shown in Figures 20 and 21, if all of the blur amounts 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96 and the judgment unit 100 judges that blur correction is not necessary, the blur correction control unit 101 performs deviation reduction control to cause the electronic blur correction unit 121 to cut out a predetermined area SA from the image IMG in accordance with the deviation between the optical axis OAL of the imaging lens 13 and the optical axis OAF of the hybrid viewfinder 14.

[0095] As shown in Fig. 21, when the determination unit 100 determines that blur correction is not necessary, conventionally, the electronic blur correction unit 121 cuts out an area DA whose center coincides with the center of the image IMG from the image IMG. However, if this is done, a scene different from the scene viewed through the hybrid viewfinder 14 is captured in the image, causing the user to feel uncomfortable. Therefore, in the third embodiment, the blur correction control unit 101 performs deviation reduction control by cutting out an area SA from the image IMG that is set in advance according to the deviation between the optical axis OAL of the imaging lens 13 and the optical axis OAF of the hybrid viewfinder 14. This provides an effect that, even if the blur correction unit is the electronic blur correction unit 121, it is possible to obtain an image close to the optical image OI by the hybrid viewfinder 14 without providing a dedicated mechanism.

[0096] The imaging device of the present disclosure may be an imaging device equipped with the mechanical blur correction unit 28 of the first embodiment and / or the mechanical blur correction unit 113 of the second embodiment, and the electronic blur correction unit 121 of the third embodiment.

[0097] [4_1 embodiment] As an example, as shown in Fig. 22, in the 4_1 embodiment, two types of thresholds 96, that is, a first threshold 961 and a second threshold 962, are stored in the storage 90. The first threshold 961 and the second threshold 962 are greater than the first threshold 961 (see Fig. 24). The first threshold 961 and the second threshold 962 are input to the determination unit 100. In addition to the blur amount 102, the detection result 125 is input to the determination unit 100 from the detection sensor 31. Although the mechanical blur correction unit 28 is illustrated in Fig. 22, the mechanical blur correction unit 113 may be used.

[0098] As an example, as shown in FIG. 23, when the detection sensor 31 detects that the user is not looking through the hybrid viewfinder 14, the determination unit 100 sets the threshold value 96 to be compared with the blur amount 102 to a first threshold value 961.

[0099] On the other hand, as an example shown in FIG. 24, when the detection sensor 31 detects that the user is looking through the hybrid viewfinder 14, the determination unit 100 sets the threshold value 96 to be compared with the blur amount 102 to a second threshold value 962.

[0100] Thus, in the 4_1 embodiment, when the detection sensor 31 detects that the user is looking into the hybrid viewfinder 14, the determination unit 100 sets the threshold value 96 to the second threshold value 962, which is a larger value, compared to when the user is not looking into the hybrid viewfinder 14. Therefore, when the user is looking into the hybrid viewfinder 14, that is, when the user is looking into the optical image OI through the hybrid viewfinder 14 to decide the composition, the blur correction control unit 101 performs the blur correction control less frequently and performs the deviation reduction control more frequently, compared to when the user is not looking into the hybrid viewfinder 14. Therefore, when the user is looking into the optical image OI through the hybrid viewfinder 14 to decide the composition, it is possible to further increase the possibility of obtaining an image close to the optical image OI through the hybrid viewfinder 14. Since an image close to the optical image OI through the hybrid viewfinder 14 is recorded in the memory card 81, the user can obtain an image as expected.

[0101] [4_2 embodiment] In the 4_2 embodiment, as in the above-mentioned 4_1 embodiment, the detection result 125 is input to the determination unit 100. However, while in the above-mentioned 4_1 embodiment, there are two types of thresholds 96 to be compared with the blur amount 102, a first threshold 961 and a second threshold 962, in the 4_2 embodiment, there is only one type of threshold, the threshold 96, to be compared with the blur amount 102.

[0102] 25, when the detection sensor 31 detects that the user is not looking through the hybrid viewfinder 14, and at least one of the amounts of blur 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than the threshold value 96, and the determination unit 100 determines that blur correction is necessary, the blur correction control unit 101 performs blur correction control to move the image sensor 25 and / or the blur correction lens 112 to a blur correction position. When the detection sensor 31 detects that the user is not looking through the hybrid viewfinder 14, and all of the amounts of blur 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96, and the determination unit 100 determines that blur correction is not necessary, the blur correction control unit 101 performs deviation reduction control to move the image sensor 25 and / or the blur correction lens 112 to a deviation reduction position.

[0103] On the other hand, as an example, as shown in FIG. 26, when the detection sensor 31 detects that the user is looking through the hybrid viewfinder 14, the blur correction control unit 101 performs blur reduction control to move the image sensor 25 and / or the blur correction lens 112 to a blur reduction position, regardless of whether blur correction is necessary or not (judgment result 103 of the judgment unit 100).

[0104] Thus, in the 4_2 embodiment, when the detection sensor 31 detects that the user is looking into the hybrid viewfinder 14, the blur correction control unit 101 performs the deviation reduction control. More specifically, when the detection sensor 31 detects that the user is looking into the hybrid viewfinder 14, the blur correction control unit 101 performs the deviation reduction control regardless of whether blur correction is necessary. For this reason, when the user is looking into the optical image OI through the hybrid viewfinder 14 to decide the composition, the blur correction control unit 101 always performs the deviation reduction control. Therefore, when the user is looking into the optical image OI through the hybrid viewfinder 14 to decide the composition, it is possible to further increase the possibility of obtaining an image close to the optical image OI by the hybrid viewfinder 14. Since an image close to the optical image OI by the hybrid viewfinder 14 is recorded in the memory card 81, the user can obtain an image as expected.

[0105] [5_1 embodiment] As an example, as shown in FIG. 27, in the 5_1 embodiment, a third threshold 963 and a fourth threshold 964 are stored in the storage 90, as in the above 4_1 embodiment. The third threshold 963 and the fourth threshold 964 are greater than the third threshold 963 (see FIG. 29). The third threshold 963 and the fourth threshold 964 are input to the determination unit 100. In addition to the blur amount 102, a switching signal 130 output from the instruction receiving unit 80 in response to the operation of the image switching lever 16 is also input to the determination unit 100. The switching signal 130 is also input to the hybrid viewfinder 14. The finder shutter 43 is opened and closed by this switching signal 130, so that the image that the user can see on the hybrid viewfinder 14 is switched between the optical image OI and the electronic image EIB. Although the mechanical blur correction unit 28 is illustrated in FIG. 27, the mechanical blur correction unit 113 may be used.

[0106] As an example, as shown in FIG. 28, when the image switching lever 16 is operated to switch from the optical image OI to the electronic image EIB and the image that the user sees in the hybrid viewfinder 14 is the electronic image EIB, the judgment unit 100 sets the threshold value 96 to be compared with the amount of blur 102 to a third threshold value 963.

[0107] On the other hand, as an example, as shown in FIG. 29, when the image switching lever 16 is operated to switch from the electronic image EIB to the optical image OI, and the image that the user sees in the hybrid viewfinder 14 is the optical image OI, the judgment unit 100 sets the threshold value 96 to be compared with the amount of blur 102 to a fourth threshold value 964.

[0108] Thus, in the 5_1 embodiment, when the image the user can see through the hybrid viewfinder 14 is the optical image OI, the determination unit 100 sets the threshold 96 to the fourth threshold 964, which is a larger value than when the image is the electronic image EIB. Therefore, when the image is switched to the optical image OI, that is, when the user is looking through the optical image OI through the hybrid viewfinder 14 to decide the composition, the blur correction control unit 101 performs the blur correction control less frequently and performs the deviation reduction control more frequently than when the image is the electronic image EIB. Therefore, when the user is looking through the optical image OI through the hybrid viewfinder 14 to decide the composition, it is possible to further increase the possibility of obtaining an image close to the optical image OI through the hybrid viewfinder 14. Since an image close to the optical image OI through the hybrid viewfinder 14 is recorded on the memory card 81, the user can obtain an image as expected.

[0109] [5_2 embodiment] In the 5_2 embodiment, as in the above-mentioned 5_1 embodiment, a switching signal 130 is input to the determination unit 100. However, while in the above-mentioned 5_1 embodiment, there are two types of thresholds 96 to be compared with the amount of blurring 102, a third threshold 963 and a fourth threshold 964, in the 5_2 embodiment, there is only one type of threshold 96 to be compared with the amount of blurring 102.

[0110] 30, when the image switching lever 16 is operated to switch from the optical image OI to the electronic image EIB, and at least one of the amounts of blur 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than the threshold value 96, and the determination unit 100 determines that blur correction is necessary, the blur correction control unit 101 performs blur correction control to move the image sensor 25 and / or the blur correction lens 112 to a blur correction position. When the image switching lever 16 is operated to switch from the optical image OI to the electronic image EIB, and all of the amounts of blur 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96, and the determination unit 100 determines that blur correction is not necessary, the blur correction control unit 101 performs deviation reduction control to move the image sensor 25 and / or the blur correction lens 112 to a deviation reduction position.

[0111] On the other hand, as an example, as shown in FIG. 31, when the image switching lever 16 is operated to switch from the electronic image EIB to the optical image OI and the image that the user sees in the hybrid viewfinder 14 is the optical image OI, the blur correction control unit 101 performs blur reduction control to move the image sensor 25 and / or the blur correction lens 112 to a blur reduction position, regardless of whether blur correction is necessary or not (determination result 103 of the determination unit 100).

[0112] Thus, in the 5_2 embodiment, when the image the user sees through the hybrid viewfinder 14 is the optical image OI, the blur correction control unit 101 performs the deviation reduction control. More specifically, when the image the user sees through the hybrid viewfinder 14 is the optical image OI, the blur correction control unit 101 performs the deviation reduction control regardless of whether blur correction is necessary. For this reason, when the electronic image EIB is switched to the optical image OI and the user is looking through the optical image OI through the hybrid viewfinder 14 to decide the composition, the blur correction control unit 101 always performs the deviation reduction control. Therefore, when the user is looking through the optical image OI through the hybrid viewfinder 14 to decide the composition, the possibility of obtaining an image close to the optical image OI through the hybrid viewfinder 14 can be further increased. Since an image close to the optical image OI through the hybrid viewfinder 14 is recorded on the memory card 81, the user can obtain an image as expected.

[0113] In each of the above embodiments, deviation reduction control is performed when all of the shake amounts 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are less than the threshold value 96, but this is not limited to the above. As an example, as shown in Fig. 32, blur correction control and deviation reduction control may be performed according to the state of shake around each of the pitch, yaw, and roll axes.

[0114] FIG. 32 illustrates a case where the amount 102 of lateral shake, which is a rotation around the roll axis (X axis), is less than the threshold value 96, and the amount 102 of vertical shake, which is a rotation around the pitch axis (Y axis), and the amount 102 of eccentric shake, which is a rotation around the yaw axis (Z axis), are all equal to or greater than the threshold value 96. In this case, the determination unit 100 determines that shake correction is not necessary for the lateral shake around the roll axis, and determines that shake correction is necessary for the vertical shake around the pitch axis and the eccentric shake around the yaw axis. The shake correction control unit 101 performs deviation reduction control without performing shake correction control for the shake around the roll axis, and performs shake correction control for the shake around the pitch axis and the yaw axis. In this way, the "shake state" according to the technology of the present disclosure may be the direction in which the shake is occurring, which is determined from the shake amount 102 for each of the pitch, yaw, and roll axes.

[0115] Also, as an example, it may be determined whether or not to perform deviation reduction control based on the judgment criteria shown in the flowchart of Fig. 33. In Fig. 33, a judgment unit 135 is provided in the CPU 91 instead of the judgment unit 100.

[0116] In FIG. 33, first, the determination unit 135 extracts high-frequency components of the shake amount 102 in a certain period (step ST200). The certain period is, for example, 2 or 3 seconds. Next, the determination unit 135 compares the extracted high-frequency components of the shake amount 102 with a preset threshold value (step ST210). If all of the high-frequency components of the shake amount 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes are less than the threshold value (YES in step ST210), the determination unit 135 determines that shake correction is not necessary (step ST220) and outputs the determination result to that effect to the shake correction control unit 101. In this case, the shake correction control unit 101 performs deviation reduction control (step ST230).

[0117] On the other hand, if at least one of the high-frequency components of the shake amount 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes is equal to or greater than the threshold value (NO in step ST210), the determination unit 100 outputs a determination result indicating that shake correction is necessary to the shake correction control unit 101. In this case, although not shown in the figure, the shake correction control unit 101 performs shake correction control. In this way, the "shake state" according to the technology of the present disclosure may be the high-frequency components of the shake amount 102.

[0118] If the high frequency components of the blur amount 102 are equal to or greater than a threshold, not performing blur correction control may result in a fatal deterioration in image quality, and therefore it is preferable to perform blur correction control. On the other hand, if the high frequency components of the blur amount 102 are less than the threshold, the quality of the blur does not have much effect on the image quality, and therefore it is preferable to perform displacement reduction control without performing blur correction control.

[0119] Alternatively, for example, it may be determined whether or not to perform deviation reduction control based on the judgment criteria shown in the flowchart of Fig. 34. In Fig. 34, a judgment unit 138 is provided in the CPU 91 instead of the judgment unit 100.

[0120] 34, the determination unit 138 times the state in which the shake amount 102 is less than the threshold value 96 (step ST300). If the state in which all of the shake amounts 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes are less than the threshold value continues for a preset period or more (YES in step ST310), the determination unit 138 determines that the device body 11 is stationary and shake correction is not necessary (step ST320), and outputs the determination result to that effect to the shake correction control unit 101. In this case, the shake correction control unit 101 performs deviation reduction control (step ST330). The determination unit 138 is an example of a "second determination unit" according to the technology of the present disclosure.

[0121] On the other hand, if the state in which all of the shake amounts 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes are less than the threshold does not continue for a preset period or more, that is, if at least one of the shake amounts 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes becomes equal to or greater than the threshold 96 (NO in step ST310), the determination unit 138 outputs a determination result that the device body 11 is not stationary and shake correction is necessary to the shake correction control unit 101. In this case, although not shown in the figure, the shake correction control unit 101 performs shake correction control.

[0122] In this way, the device may include a determination unit 138 that determines whether or not the device body 11 is stationary, and the blur correction control unit 101 may perform deviation reduction control based on the result of the determination by the determination unit 138. When the device body 11 is stationary and there is no need to perform blur correction control, the resources of the blur correction unit can be diverted to deviation reduction control, which can promote effective use of the blur correction unit. Note that the blur correction unit in this case may be any of the mechanical blur correction unit 28 of the first embodiment, the mechanical blur correction unit 113 of the second embodiment, and / or the electronic blur correction unit 121 of the third embodiment.

[0123] Furthermore, as an example, as shown in FIG. 35, a determination unit 150 may be constructed in the CPU 91 instead of the determination unit 100, and may determine whether or not to perform deviation reduction control as follows.

[0124] A detection signal 152 from an attachment detection sensor 151 is input to the determination unit 150. The attachment detection sensor 151 is, for example, a contact detection sensor, and detects whether a fixture such as a tripod is attached to the screw hole 32 and the device body 11 is attached to the fixture. The detection signal 152 is, for example, a high signal when a fixture is attached to the screw hole 32, and a low signal when a fixture is not attached to the screw hole 32. The determination unit 150 outputs a determination result 153 according to the detection signal 152 to the blur correction control unit 101. The determination unit 150 is an example of a "third determination unit" according to the technology of the present disclosure.

[0125] 36, when a detection signal 152 indicating that a fastener is attached to a screw hole 32 is input from an attachment detection sensor 151, the determination unit 150 outputs a determination result 153 indicating that blur correction is not necessary to the blur correction control unit 101. In this case, the blur correction control unit 101 performs deviation reduction control.

[0126] In this way, the device may include a determination unit 150 that determines whether or not the device body 11 is attached to a fixture, and the blur correction control unit 101 may perform deviation reduction control based on a determination result 153 by the determination unit 150. When the device body 11 is attached to a fixture and there is no need to perform blur correction control, the resources of the blur correction unit can be diverted to deviation reduction control, which can promote effective use of the blur correction unit. Note that the blur correction unit in this case may also be any of the mechanical blur correction unit 28 of the first embodiment, the mechanical blur correction unit 113 of the second embodiment, and / or the electronic blur correction unit 121 of the third embodiment.

[0127] [Sixth embodiment] 37 as an example, a device body 156 of an imaging device 155 of the sixth embodiment is provided with an attachment section 157. Any of the interchangeable hybrid viewfinders 141, 142, 143 that are separate from the device body 156 is detachably attached to the attachment section 157. The attachment section 157 has an identification section that identifies which of the hybrid viewfinders 141 to 143 has been attached. The identification section is realized by, for example, a communication section that receives identification signals from the hybrid viewfinders 141 to 143 via wired or wireless communication.

[0128] The hybrid viewfinders 141-143 have different heights in the Z-axis direction for the convenience of the user. Therefore, the positions of the optical axes OAF1, OAF2, and OAF3 are also different. Therefore, when the hybrid viewfinders 141-143 are attached to the attachment portion 157 and integrated with the device body 156, their positional relationships with the optical axis OAL of the imaging lens 13 are also different. Therefore, the deviation reduction positions of the hybrid viewfinders 141-143 are registered in the deviation reduction position information 97 of the sixth embodiment. The blur correction control portion 101 performs deviation reduction control by moving the imaging element 25 and / or the blur correction lens 112 to the deviation reduction position corresponding to the hybrid viewfinder 14 identified by the identification portion of the attachment portion 157.

[0129] Thus, in the sixth embodiment, the hybrid viewfinders 141-143 are separate from the device body 156 and can be removed and / or replaced. For this reason, a wide variety of hybrid viewfinders 14 can be used. Note that the types of hybrid viewfinders 14 are not limited to the three types shown in the example. There may be two types, or four or more types. Furthermore, the optical images OI of the multiple types of hybrid viewfinders 14 may be different.

[0130] [Seventh embodiment] As an example, as shown in FIG. 38, two hybrid viewfinders 144 and 145 are provided in a device body 161 of an imaging device 160 of the seventh embodiment. The hybrid viewfinder 144 is disposed at the upper right end of the device body 161, similar to the hybrid viewfinder 14 of the first embodiment and the like. In contrast, the hybrid viewfinder 145 is disposed at the lower left end of the device body 161, diagonally opposite to the hybrid viewfinder 144. The hybrid viewfinder 145 is provided for use in so-called vertical shooting. Vertical shooting is a method of shooting by holding the top surface 162 and the bottom surface 163 of the device body 161 in a state where they are substantially parallel to the Z-axis direction (vertical direction). Although not shown in the figure, a detection window is also provided near the hybrid viewfinder 145, in which a detection sensor is built in to detect whether or not a user is looking into the hybrid viewfinder 145.

[0131] Since the hybrid viewfinders 144, 145 are disposed at different positions, their optical axes OAF4, OAF5 are naturally different as well. Furthermore, their positional relationships with the optical axis OAL of the imaging lens 13 are also different. For this reason, also in the seventh embodiment, similarly to the sixth embodiment, the displacement reduction positions of each of the hybrid viewfinders 144, 145 are registered in the displacement reduction position information 97. The blur correction control unit 101 performs displacement reduction control by moving the imaging element 25 and / or the blur correction lens 112 to the displacement reduction position corresponding to the hybrid viewfinder 14 that is detected as the user is looking through.

[0132] In this way, in the seventh embodiment, a plurality of hybrid viewfinders 14 are provided. This can improve usability for the user. Note that in addition to or instead of the hybrid viewfinder 14, a plurality of imaging lenses 13 may be provided.

[0133] [Eighth embodiment] 39 as an example, in the eighth embodiment, zoom lens position information 170 is input to the blur correction control unit 101. As described above, the zoom lens position information 170 is information that indicates the position of the zoom lens 57 on the optical axis OAL, which is derived from the driving amount of the zoom motor.

[0134] The blur correction control unit 101 also receives change amount information 171. The change amount information 171 registers the amount of change in the deviation between the optical axis OAL and the optical axis OAF for each position of the zoom lens 57. The blur correction control unit 101 reads out the amount of change corresponding to the position of the zoom lens 57 indicated by the zoom lens position information 170 from the change amount information 171. Then, the blur correction control unit 101 corrects the deviation reduction position of the deviation reduction position information 97 by the amount of the read change, and then performs deviation reduction control.

[0135] Due to mechanical errors and the like, the optical axis OAL of the imaging lens 13 may change slightly as the zoom lens 57 moves, which may cause a change in the amount of deviation between the optical axis OAL and the optical axis OAF. In this eighth embodiment, the blur correction control unit 101 performs deviation reduction control by correcting the amount of change. This makes it possible to correctly deal with changes in the deviation between the image angle of view AV and the optical image OI captured by the hybrid viewfinder 14 that occur as the zoom lens 57 moves. It becomes possible to obtain an image close to the optical image OI captured by the hybrid viewfinder 14, regardless of the position of the zoom lens 57.

[0136] In addition, in FIG. 39, the movement of the zoom lens 57 is given as an example of the operation of the imaging lens 13 that changes the positional relationship between the optical axis OAL and the optical axis OAF, but the present invention is not limited to this. The movement of the focus lens 56 is also given as an example of the operation of the imaging lens 13 that changes the positional relationship between the optical axis OAL and the optical axis OAF. If the imaging lens 13 is provided with a tilt mechanism or a shift mechanism, the operation of the tilt mechanism or the shift mechanism also becomes a factor that changes the positional relationship between the optical axis OAL and the optical axis OAF. Furthermore, in addition to the operation of the imaging lens 13, if a zoom lens is installed in the hybrid viewfinder 14, the movement of the zoom lens also becomes a factor that changes the positional relationship between the optical axis OAL and the optical axis OAF. In either case, the blur correction control unit 101 may perform deviation reduction control by correcting the amount of change.

[0137] [Ninth embodiment] 40 as an example, in the ninth embodiment, tilt angle information 180 is input to the blur correction control unit 101. The tilt angle information 180 is information on the tilt angle of the image sensor 25 around the optical axis OAF and the optical axis OAL relative to the hybrid viewfinder 14, and is stored in the storage 90. The tilt angle information 180 registers the tilt angle of the image sensor 25 that is actually measured in an inspection of the imaging device 10 at the time of shipment.

[0138] The blur correction control unit 101 performs control to correct the tilt of the image sensor 25 in the tilt angle information 180 (hereinafter referred to as tilt correction control). Specifically, the blur correction control unit 101 outputs a control signal 104 to the correction unit driver 68, the content of which is to eliminate or reduce the tilt of the image sensor 25 registered in the tilt angle information 180, and operates the mechanical blur correction unit 28. Note that, as can be seen from the above-mentioned expression "eliminate or reduce the tilt of the image sensor 25", "correcting the tilt" includes the meaning of reducing the tilt in addition to eliminating the tilt.

[0139] As in the embodiment shown in FIG. 10, when the amount of shake 102 is equal to or greater than the threshold value 96, more specifically, when at least one of the amounts of shake 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes is equal to or greater than the threshold value 96, the determination unit 100 outputs a determination result 103 indicating that shake correction is necessary to the shake correction control unit 101. In this case, the shake correction control unit 101 performs shake correction control. On the other hand, as shown in FIG. 41 as an example, when the amount of shake 102 is less than the threshold value 96, more specifically, when all of the amounts of shake 102 detected by the angular velocity sensors 30 of the pitch, yaw, and roll axes are less than the threshold value 96, the determination unit 100 outputs a determination result 103 indicating that shake correction is not necessary to the shake correction control unit 101. In this case, the shake correction control unit 101 performs tilt correction control.

[0140] Ideally, the hybrid viewfinder 14 and the image sensor 25 are assembled into the device body 11 without tilting around the optical axis OAF and the optical axis OAL, but there are cases where tilting occurs due to an error during assembly. In this ninth embodiment, the blur correction control unit 101 performs control to correct the tilt of the image sensor 25 around the optical axis OAF and the optical axis OAL relative to the hybrid viewfinder 14, that is, tilt correction control. In this way, as shown in FIG. 42 as an example, it is possible to eliminate or reduce the deviation between the optical image OI by the hybrid viewfinder 14 and the image IMG output from the image sensor 25. Humans can sense that one of two images showing the same scene is tilted by even 0.5° with respect to the other. Therefore, by performing such tilt correction control, it is possible to further reduce the possibility that the user will feel uncomfortable.

[0141] 41, tilt correction control is performed when the shake amounts 102 detected by the angular velocity sensors 30 for the pitch, yaw, and roll axes are all less than the threshold value 96, but this is not limiting. For example, as shown in FIG 43, tilt correction control may be performed depending on the state of shake around the roll axis.

[0142] 43 illustrates an example in which the amount 102 of lateral shake, which is rotation around the roll axis (X axis), is less than the threshold value 96. In this case, the determination unit 100 determines that shake correction is not necessary for the lateral shake around the roll axis. Therefore, the shake correction control unit 101 performs tilt correction control.

[0143] 40, the mechanical blur correction unit 28 is shown as an example of the blur correction unit, but the present invention is not limited to this. The electronic blur correction unit 121 of the third embodiment may also be used. In the case of the electronic blur correction unit 121, tilt correction control is performed by cutting out an area that eliminates or reduces the tilt of the image sensor 25 from the image IMG output by the image sensor 25.

[0144] It is also possible to eliminate the angular velocity sensor 30 for the roll axis and to configure such that blur correction for lateral shake, which is rotation around the roll axis, is not performed.

[0145] In each of the above embodiments, the hybrid viewfinder 14 that combines the functions of an optical viewfinder and an electronic viewfinder has been exemplified, but the viewfinder may be a purely optical viewfinder that does not have the function of an electronic viewfinder.

[0146] The imaging device according to the technique of the present disclosure may be a single-lens reflex digital camera, a smartphone, or a tablet terminal.

[0147] In each of the above embodiments, the following various processors can be used as the hardware structure of the processing units that perform various processes, such as the image processing unit 75, the display control unit 78, the instruction receiving unit 80, the determination units 100, 135, and 138, the blur correction control unit 101, and the electronic blur correction unit 121. The various processors include the CPU 91, which is a general-purpose processor that executes software (operation program 95) and functions as various processing units, as well as programmable logic devices (PLDs) that are processors whose circuit configuration can be changed after manufacture, such as a field programmable gate array (FPGA), and / or dedicated electric circuits that are processors having a circuit configuration designed specifically for executing specific processes, such as an application specific integrated circuit (ASIC).

[0148] A single processing unit may be composed of one of these various processors, or may be composed of a combination of two or more processors of the same or different types (e.g., a combination of multiple FPGAs and / or a combination of a CPU and an FPGA). Also, multiple processing units may be composed of a single processor.

[0149] As an example of configuring multiple processing units with one processor, first, there is a form in which one processor is configured with a combination of one or more CPUs and software, as typified by computers such as client and server, and this processor functions as multiple processing units. Second, there is a form in which a processor is used that realizes the functions of the entire system including multiple processing units with one IC (Integrated Circuit) chip, as typified by System On Chip (SoC), etc. In this way, the various processing units are configured using one or more of the above various processors as a hardware structure.

[0150] Furthermore, more specifically, the hardware structure of these various processors can be an electric circuit that combines circuit elements such as semiconductor elements.
